Ingredients

  • 1 medium whole spaghetti squash
  • 3 tablespoons olive oil, divided
  • 1 tablespoon kosher salt, divided
  • 1 tablespoon Italian seasoning, divided
  • 1 teaspoon black pepper, divided
  • 1 medium yellow onion, diced
  • 3 cloves garlic, minced
  • ½ teaspoon red pepper flakes
  • 8 ounces ricotta cheese
  • 4 ounces mozzarella cheese
  • 3 ounces parmesan cheese

Instructions

  • Preheat your air fryer to 400°F. Cut the spaghetti squash in half lengthwise, then scoop out the seeds. Season the insides of the squash generously with about 2 teaspoons of salt, ½ teaspoon black pepper, 1 teaspoon of Italian seasoning, and 2 tablespoons of olive oil. Air fry until soft and tender, about 15-20 minutes.
  • Meanwhile, in a skillet on the stovetop, heat the remaining olive oil, then add onion with a pinch of salt. Cook until softened, about 3-5 minutes, then add garlic, Italian seasoning, and red pepper flakes and cook until garlic is fragrant- about 30 seconds. Add the onion, garlic, and seasoning mixture to the ricotta, parmesan, and mozzarella and mix well.
  • Add the cheese mixture to the insides of the spaghetti squash and air fry for 3-5 minutes at 400°F until cheese is golden brown. Garnish with fresh herbs, salt, and pepper. Enjoy!
  • Store in an airtight container in the fridge for up to 3 days.

Notes

  • Feel free to swap garlic and onion for garlic and onion powder.
  • Red pepper flakes and fresh herbs are optional and to taste.
  • If you like, you can skip the cheesy herbed filling altogether, but please note the nutrition facts include these ingredients.
