Ingredient Notes & Substitutions

Crafting the perfect Air Fryer Spaghetti Squash begins with understanding your ingredients. Here’s a closer look at what you’ll need and how to customize it:

• Spaghetti Squash: The star of our show! For optimal results and to ensure it fits perfectly in most air fryer baskets, aim for a medium-sized squash, typically around 2.5 pounds. You’ll find detailed instructions on how to select and prepare your spaghetti squash in the sections below. Its mild, slightly sweet flavor is what makes it such a versatile base for various toppings.
• Mozzarella Cheese: This cheese contributes to the wonderful gooey, melty texture of our topping. The recipe calls for 3/4 cup, but feel free to adjust to your preference. For a lighter, less intensely cheesy squash, you can reduce the amount to 1/2 cup. Conversely, if you’re a true cheese lover, a full cup will make it extra decadent. Other great melting cheeses like provolone or a Monterey Jack blend can also work as substitutions.
• Cream Cheese & Unsalted Butter: These are crucial for creating the rich, creamy base of our topping. Ensure both are softened to room temperature before mixing. This allows for a smooth, lump-free blend, making it easier to spread over the cooked squash. Using unsalted butter gives you better control over the overall sodium content.
• Fresh Garlic: While garlic powder is convenient, fresh minced garlic offers an unparalleled depth of flavor. It brings a pungent, aromatic kick that really brightens the cheesy topping. Don’t skip this for the best results!
• Italian Seasoning: A blend of dried herbs like oregano, basil, thyme, and rosemary, Italian seasoning provides a classic, savory profile to the cheese mixture. If you don’t have a pre-made blend, you can combine individual herbs from your pantry.
• Parmesan Cheese: Adds a salty, umami depth that complements the mozzarella and cream cheese beautifully. Freshly grated Parmesan will always offer superior flavor compared to pre-grated varieties.
• Olive Oil, Salt, and Pepper: These basic seasonings are essential for flavoring the spaghetti squash itself before air frying. A good quality olive oil helps in caramelization and ensures the squash doesn’t dry out, while salt and pepper enhance its natural taste.

A complete list of ingredients and precise amounts is conveniently located on the recipe card below for your convenience.

How To Pick Spaghetti Squash

Selecting the right spaghetti squash is the first step to a successful and delicious meal. Here’s what to look for to ensure you get a perfectly ripe and flavorful squash:

• Size Matters: Aim for a squash that is approximately 2.5 pounds. This size is ideal for fitting comfortably into most air fryer baskets, ensuring even cooking. Always use the scale at the grocery store to confirm the weight, as an overly large squash may require longer cooking times or might not fit at all.
• Inspect the Exterior: Carefully examine the squash for any imperfections. Avoid squashes with brown spots, soft or mushy areas, or visible cracks. These can indicate spoilage or damage, which will affect the texture and taste. A healthy squash will have a smooth, unblemished surface.
• Firmness and Weight: Pick up the squash and feel its weight. It should feel firm and heavy for its size. This indicates a good moisture content and ripeness. A squash that feels light or hollow might be dried out or underripe.
• Color is Key: The color of your spaghetti squash is a crucial indicator of its ripeness. Look for a squash with a bright, vibrant yellow hue. A pale yellow or greenish tint usually means the squash is not fully ripe and might lack the characteristic flavor and tender, stringy texture you desire. The brighter the yellow, the sweeter and more flavorful the squash is likely to be.
• Stem Condition: While not as critical as other factors, a dry, firm stem is generally a good sign. Avoid squashes with soft or moldy stems, which can suggest decay.

How To Prepare Spaghetti Squash

Preparing spaghetti squash can seem daunting due to its tough exterior, but with a few careful steps, it becomes quite manageable. Follow these instructions to get your squash ready for the air fryer:

1. Wash and Dry Thoroughly: Begin by washing the exterior of the spaghetti squash under cool running water. Use a vegetable brush to scrub away any dirt or debris. Once clean, dry the squash completely with a towel. This ensures a clean cutting surface and prevents your knife from slipping.
2. Careful Halving: Place the squash on a stable cutting board. Using a sharp, sturdy chef’s knife, carefully cut the squash in half lengthwise from stem to end. This can be challenging due to its hard shell. Work slowly and apply steady pressure. If the squash is particularly hard, you can carefully pierce it a few times with the tip of your knife or microwave it for 2-3 minutes to soften the skin slightly before cutting. Try to get the halves as even as possible to ensure uniform cooking.
3. Remove the Seeds: Once halved, you’ll see the fibrous strands and seeds in the center. Use a sturdy spoon or an ice cream scoop to scrape out all the seeds and stringy pulp. Discard these, leaving the inner cavity clean. This step is similar to preparing a pumpkin for carving.
4. Keep the Ends Intact: There’s no need to remove the stem or the very end of the squash. Leaving the ends intact serves a practical purpose: it helps contain the “spaghetti” strands within the shell during cooking. This allows you to serve and eat directly out of the squash halves like natural bowls, making for a beautiful presentation and less mess.

How To Make Spaghetti Squash

Creating this cheesy Air Fryer Spaghetti Squash is a straightforward process, broken down into a few simple stages. Get ready to enjoy a healthy and satisfying meal with minimal fuss.

Quick Overview

• First, you’ll prepare and season the squash halves.
• Next, the squash cooks to tender perfection in your air fryer.
• While the squash roasts, you’ll whip up the delectable cheesy topping.
• Finally, the cooked squash is generously topped with the cheese mixture and air-fried until golden and bubbly.

Step by Step Instructions

Step 1: Prepare the squash halves by brushing the inside, cut-side up, with a tablespoon of olive oil. Ensure an even coating to promote browning and prevent sticking. Generously season each half with one teaspoon of salt and half a teaspoon of freshly ground black pepper. Carefully place the seasoned squash halves cut side up in the air fryer basket. Arranging them cut side up allows moisture to escape, leading to a more tender and flavorful result.

Step 2: Air fry the spaghetti squash at 360 degrees Fahrenheit (approximately 182 degrees Celsius) for 22-28 minutes. The exact cooking time may vary slightly depending on the size of your squash and the specific model of your air fryer. The goal is for the squash to be fork-tender, meaning a fork should easily pierce through the flesh with little resistance. This indicates it’s cooked through and ready for the next step.

Step 3: While the spaghetti squash is air frying, prepare the irresistible cheesy topping. In a medium bowl, combine the softened cream cheese, unsalted butter, minced fresh garlic, and Italian seasoning. Use a fork to thoroughly mash these ingredients together until they form a relatively smooth, well-combined mixture. Then, stir in the shredded mozzarella and Parmesan cheese until everything is fully incorporated. The mixture will be thick and rich.

Step 4: Once the spaghetti squash is perfectly fork-tender and removed from the air fryer, it’s time to add the delicious topping. Divide the cheesy mixture evenly between the two squash halves. Use the back of a spoon or a spatula to spread the topping smoothly and generously over the entire cut surface of each squash half, ensuring every bite will be full of cheesy goodness.

Step 5: Return the topped spaghetti squash halves to the air fryer basket. Air fry them at a higher temperature of 400 degrees Fahrenheit (approximately 200 degrees Celsius) for a short duration of 2-3 minutes. This quick burst of high heat is just enough to perfectly melt the cheese topping until it’s bubbly and slightly golden. Watch it closely to prevent burning, as air fryers can heat quickly at this temperature.

Recipe Serving Suggestions

Spaghetti squash, with its naturally mild flavor and pasta-like strands, serves as an exceptional low-carb substitute for traditional pasta or rice. Its subtle taste makes it incredibly versatile, pairing beautifully with a vast array of flavors and sauces. The possibilities for customization are truly endless, allowing you to tailor this healthy dish to your cravings. Here are some of my favorite go-to suggestions to inspire your next meal:

• Hearty Marinara Sauce: A classic pairing! The bright, tangy notes of a good marinara sauce complement the creamy cheese topping perfectly. Consider my Hearty Marinara Sauce recipe for a homemade touch, and feel free to add ground beef, Italian sausage, or a medley of sautéed vegetables for an even more substantial meal.
• Creamy Alfredo Sauce: Lean into the “fettuccine alfredo” vibes by drizzling your air-fried spaghetti squash with a rich and velvety alfredo sauce. This creates an incredibly indulgent yet still low-carb meal. Grilled chicken or sautéed shrimp would be fantastic additions here.
• Elegant Pink Lobster Ravioli Sauce: For a more gourmet experience, try serving it with a luscious pink sauce, similar to my Pink Lobster Ravioli Sauce. The delicate flavors of such a sauce elevate the squash into a sophisticated dish.
• Fresh Pesto: Brighten up your meal with a generous dollop of basil pesto. Its herbaceous, garlicky, and nutty notes provide a wonderful contrast to the rich cheese topping. Sun-dried tomato pesto is another excellent variation.
• Roasted Vegetables: Enhance the nutritional profile and add textural variety by serving alongside or mixed with a medley of roasted vegetables. Kale, onions, zucchini, broccoli, cauliflower, or mushrooms all roast beautifully and provide earthy flavors.
• Savory Proteins: Transform this side into a complete main course by adding your favorite protein. Ideas include juicy Olive Garden Slow Cooker Chicken, lean chicken sausage, flavorful ground beef (seasoned with Italian herbs), or simply pan-seared sliced chicken breast.

Ultimately, don’t hesitate to experiment! Use your favorite pasta sauce, or get creative with seasonings and other vegetables to make this Air Fryer Spaghetti Squash truly your own.

Expert Tips & Variations

Mastering Air Fryer Spaghetti Squash is easy, but a few expert tips and creative variations can elevate your dish from good to gourmet. Here’s how to perfect your technique and customize your meal:

• Even Halving is Key: When cutting the spaghetti squash in half lengthwise, strive for halves that are as even as possible. This ensures both pieces cook uniformly in the air fryer, reaching fork-tender doneness at roughly the same time. Uneven halves can lead to one side being overcooked or undercooked.
• Adjust Cook Time as Needed: Remember that not all air fryers are created equal; cooking temperatures and times can vary between models. Always use a fork to test the squash for tenderness. If it’s not easily pierced after the initial cooking time, return it to the air fryer for additional 3-5 minute increments until it reaches the desired softness. Similarly, smaller squashes may cook faster.
• Don’t Overcrowd the Air Fryer: For the best results, ensure there’s enough space around the squash halves for air to circulate freely. If your air fryer basket is small, you might need to cook the halves one at a time, especially if they are larger. Overcrowding can lead to steaming rather than roasting, preventing proper caramelization and tenderness.
• Enhance the Topping: Get creative with your cheesy topping! Consider adding a pinch of red pepper flakes for a subtle kick, a sprinkle of fresh herbs like chopped parsley or chives for brightness, or a dash of nutmeg for a hint of warmth. You can also experiment with other cheeses like smoked gouda, white cheddar, or a touch of Asiago for different flavor profiles.
• Add Vegetables to the “Boat”: For an all-in-one meal, sauté some finely diced vegetables such as bell peppers, onions, spinach, or mushrooms, and mix them into the cheesy topping before the final air fry. This adds more nutrients, flavor, and texture.
• Introduce a Protein: To make it a complete meal, consider adding cooked, shredded chicken, crumbled bacon, or small pieces of cooked sausage directly into the squash boats along with the cheesy topping before the final air fry.
• Spice it Up: Beyond Italian seasoning, explore other spice blends. A sprinkle of smoked paprika, a touch of cumin, or even a curry powder blend can transform the flavor profile of your squash.
• Sweet Spaghetti Squash: While this recipe is savory, spaghetti squash can also go sweet! Omit the savory topping and instead drizzle with maple syrup, cinnamon, and a pat of butter for a delightful dessert or breakfast side.

How To Store & Reheat

This Air Fryer Spaghetti Squash is wonderful for meal prepping or enjoying as leftovers. Proper storage and reheating ensure that its delicious flavor and texture are preserved. Here’s a comprehensive guide:

• Refrigerator Storage: If you have leftover spaghetti squash still in its shell with the cheesy topping, allow it to cool completely to room temperature. Then, wrap each half tightly in plastic wrap or aluminum foil, or transfer them to an airtight container. Store in the refrigerator for 2-3 days. The key is to minimize air exposure to maintain freshness.
• Freezer Storage: For longer storage, it’s best to remove the “spaghetti” strands from the skin completely. Use a fork to scrape out the squash strands, leaving the skin behind. Transfer the plain squash strands (without the cheesy topping) to an airtight freezer-safe container or a heavy-duty freezer bag. Squeeze out as much air as possible if using a bag to prevent freezer burn. You can store spaghetti squash in the freezer for 2-3 months. If you wish to freeze the cheesy topping separately, store it in a small airtight container.
• Reheating from the Fridge (Whole Halves): To reheat individual squash halves with the topping, you have a couple of options.
  • Microwave: Place a squash half on a microwave-safe plate. Cover it loosely with a damp paper towel to help retain moisture. Microwave on medium power for 2-4 minutes, or until heated through.
  • Air Fryer: For best results, especially if you want to crisp up the cheese again, reheat in the air fryer at 350 degrees Fahrenheit (175 degrees Celsius) for 5-8 minutes, or until the squash is hot and the cheese is bubbly.
• Reheating from the Fridge (Strands): If you’ve stored just the strands, reheat them in the microwave, or sauté them gently in a pan with a splash of water or broth to prevent drying.
• Reheating from Frozen (Strands): When reheating frozen spaghetti squash strands, transfer them to a saucepan and heat covered over medium-low heat on the stove. Stir frequently to break up any ice and ensure even heating. The squash will release some liquid as it thaws and heats; uncover at the end and increase the heat slightly to cook off any excess liquid and prevent sogginess. Once heated through, you can then add your fresh or frozen/thawed cheesy topping and finish in the air fryer or microwave.

Oven Method

While the air fryer offers unmatched speed and efficiency for this recipe, you can certainly achieve equally delicious results using a traditional oven. This method is particularly useful if you don’t own an air fryer or are cooking a larger quantity of squash. Here’s how to roast spaghetti squash in the oven:

1. Preheat and Prepare: Start by preheating your oven to 400 degrees Fahrenheit (200 degrees Celsius). Prepare the spaghetti squash as outlined above: wash, dry, carefully cut in half lengthwise, and scoop out the seeds and fibrous strands.
2. Pierce and Season: Before seasoning, use a fork to pierce the skin of each squash half a few times. This helps steam escape during roasting, preventing the squash from bursting and ensuring even cooking. Brush the inside of each squash half with olive oil, then season generously with salt and pepper, just as you would for the air fryer method.
3. Bake to Tenderness: Place the seasoned squash halves cut side down on a baking sheet lined with parchment paper. Parchment paper is essential for easy cleanup and prevents the squash from sticking. Roasting cut side down allows the squash to steam in its own moisture, resulting in a very tender interior. Bake for 40-50 minutes, or until the squash is completely fork-tender. The exact time will depend on the size of your squash; larger ones may need a bit longer.
4. Add Topping and Broil: Once the squash is cooked, carefully remove the baking sheet from the oven. Flip the squash halves so they are cut side up. Spread the prepared cheesy mixture evenly on top of each half. Return the baking sheet to the oven and switch your oven to the broiler setting. Broil for 2-4 minutes, keeping a very close eye on it, until the cheese is beautifully melted, bubbly, and lightly browned to your preference. Be cautious, as broilers can quickly burn food.
5. Serve: Allow to cool slightly before using a fork to scrape out the spaghetti-like strands and incorporating the melted cheese. Serve hot, either in its shell or transferred to a bowl.
