What Kind of Butternut Squash to Use

You can buy it “pre-cubed” or whole. If you purchase a whole squash, Katie over at Hey Nutrition Lady has a great tutorial on how to cut a butternut squash.

I have used frozen squash in the air fryer. I find it works best if the air fryer has been preheated for two minutes before adding the squash. And do not defrost the squash before cooking. Related: How to Roast Frozen Vegetables

I also highly recommend tossing the frozen squash cubes in 1 tsp of cornstarch (arrowroot for Whole30 or paleo) to make it the crispest ever.


I like to use it as a side for my paleo roasted chickenPaleo Salmon Cakes, or incorporate it into a sheet pan dinner. And we love to top it with Sweet Potato Fries Dipping Sauce or Homemade Cilantro Chimichurri.

And if you have any squash leftover, make some Spicy Vegan Butternut Squash Soup or this Butternut Squash Chili. And if you want to make something fun, check out these Baked Butternut Squash Fries.

Pro Tips/Recipe Notes

  • Do your best to cut the squash into uniform pieces to ensure even cooking.
  • If you’d like the squash to cook faster, cut the pieces small; almost diced. Check after 10 minutes of cooking.
  • You can cook the squash ahead of time as part of your easy healthy meal prep. To reheat, pop them back into the air fryer for 5 minutes at 400 degrees F.
  • Every person prefers their veggies roasted to a specific level. Use common sense and check on your squash during the cooking process to see what works best for you.


  • Like a sweeter version? Add 2 tbsp of maple syrup (fine for paleo but not Whole30), 1/2 tsp of cinnamon, and a pinch of cayenne pepper. 
  • Add other root veggies like air fryer brussels sprouts, parsnips, turnips, onion, and air fryer roasted beets for an amazing ginormous roasted veg extravaganza.
  • If you have leftovers, mash them up and add flour (use almond flour to make it paleo, gluten-free, and Whole30 compliant) tablespoon by tablespoon until the mixture is barely sticky. Make into patties. Heat avocado or coconut oil in a skillet over medium heat. Cook until the bottom is light brown and has a crunchy sear (2-3 minutes). Flip and cook the other side. Remove to a plate lined with a paper towel or newspaper.
