Spaghetti Squash (Air Fryer)

This Spaghetti Squash (Air Fryer) is the perfect healthy and low carb dinner recipe. It takes less than 30 minutes to roast the squash in the air fryer and comes out perfectly caramelized and tender. I like to top the spaghetti squash boats with a mixture of cheeses, garlic, and herbs for a healthier and easier take on alfredo.

  • 1 medium spaghetti squash (about 2 ½ pounds), halved and seeds removed*
  • 1 Tablespoon olive oil
  • 1 teaspoon salt
  • ½ teaspoon pepper

Optional Cheese Topping

  • 2 ounces cream cheese softened to room temperature
  • 2 Tablespoons unsalted butter softened to room temperature
  • 3 cloves garlic
  • 1 Tablespoon Italian seasoning
  • ¾ cup shredded mozzarella cheese*
  • ¼ cup shredded parmesan cheese


  • Brush the inside of each squash half with olive oil. Season each with salt and pepper. Place the squash halves cut side up in the air fryer basket.
  • Air fry at 360 degrees for 22-28 minutes, or until the squash is fork tender.
  • While the squash is cooking, make the cheesy topping. Using a fork mash together the cream cheese, butter, garlic, and Italian seasoning. Stir in the mozzarella and parmesan cheese.
  • Once the spaghetti squash is done, spread the topping evenly on top of each half.
  • Air fry at 400 degrees for 2-3 minutes or until the cheese has melted.
  • Use a fork to scrape and fluff the “spaghetti” strands until the cheese topping is well incorporated. Serve in the skin as a boat or remove and transfer it to a bowl.


Spaghetti Squash: See the section below for details about how to prepare a spaghetti squash.
Mozzarella: Reduce to ½ cup for a less cheesy squash.
Refrigerator: Store leftover air fryer spaghetti squash in an airtight container in the fridge for 3-4 days.
Freezer: If you are going to freeze the spaghetti squash (air fryer), remove the “spaghetti” strands from the skin completely and transfer them to an airtight container or bag. Store in the freezer for 2-3 months.
Cut the spaghetti squash evenly in half. This ensures each half takes about the same time to cook.
Every air fryer cooks differently. With all air fryer recipes, I recommend quickly checking on the food at least once during the cooking process. If it appears to be browning too quickly, lower the temperature by 10 degrees. If it seems like it is cooking too slow, increase the temperature by 10 degrees. You can also add more time at the end.
