Roast spaghetti squash in less than half the time by using this Ninja Foodi Air Fryer Spaghetti Squash recipe. It takes about 20 minutes and a few simple ingredients to have a low carb noodle replacement to pair with my Italian Sausage Meatballs, Cajun Shrimp Alfredo or Shrimp Scampi.

Why Make This
- Takes less than half the time: If you’ve ever roasted a spaghetti squash in the oven, then you know it takes at least 40 minutes. Sometimes, it can take over an hour. With this recipe, you pop your spaghetti squash in the air fryer and it’s ready in about 20 minutes.
- Simple & easy: this recipe requires five simple ingredients and two main steps to make.
Ingredients Needed
- Spaghetti Squash: I cut it in half lengthwise.
- Avocado Oil: I divided this evenly between the two halves. If you don’t have avocado oil, you can use any other oil for air frying that you prefer.
- Sea Salt: I divided this evenly between the two halves
- 24 Herb Sprinkle Seasoning: I divided this evenly between the two halves
- Parmesan Cheese: I used the refrigerated grated kind and divided it evenly between the two halves

How to Make Spaghetti Squash Using an Air Fryer
- Drizzle the avocado oil, sea salt, and sprinkle seasoning on top of the squash.
- Add both pieces (so that they are open side up) to the air fryer basket.
- Air Crisp on 400 degrees for 20-22 minutes, or until tender.
- Top with parmesan cheese. Use a fork to scrape some of the “noodles” free.

Top Tips & FAQs
- Consider the size of your air fryer when getting squash: I prefer to have one big enough so that two pieces can sit side-by-side in the air fryer basket.
- Cut the squash with a sharp knife: I simply cut my squash in half with a sharp knife. But, if you’re having trouble, then you can soften the spaghetti squash before cutting it. I included a link to a more detailed post below about strategies to cut your squash
- Adjust the cook time if you soften your squash: if you need to soften your squash in the microwave in order to cut it, then it will take less time to cook in the air fryer. I recommend checking on your squash at the 10 and 15 minute mark.
- Face the squash up: the heating element in the Ninja Foodi is above the food. So, I face my squash up to have it roast evenly.
Yes. I haven’t tried this, but some people put their spaghetti squash to the microwave to soften it. You cut slits in the squash and heat it for a few minutes.
Generally, you can reheat food in your air fryer by using a lower temperature. I haven’t tried reheating my squash though since I use the entire squash for a meal.
I personally just used a sharp knife and found cutting a spaghetti spaghetti squash easily. But, if you’re having trouble some tips to cut a spaghetti squash are in the linked tutorial.
