I get a lot of questions about air-fryers and whether or not it’s worth adding another appliance to your kitchen. I was also skeptical of getting an air-fryer but now I really love mine and use it daily.

Most air-fryers don’t have to be pre-heated either, which makes cooking faster and simpler. New to air-frying? Check out my post with the pros and cons of air frying. Or, see my list of the best air fryers under $100.

This recipe for Air Fryer Butternut Squash Cubes is a perfect example of a simple and great side dish that you make without having to use your big kitchen oven.

Why You Need This Recipe

  • Use your air-fryer to make this recipe if you don’t have space in your oven, or you don’t want to heat up your entire oven.

  • Increase the cooking time to 45 minutes if you want to make this in a regular oven.

  • Butternut squash is high in beta-carotene, fiber, and antioxidants.

Key Ingredients

I used pre-cut butternut squash for this recipe because I don’t like peeling and cutting a whole squash. You can buy pre-cut squash in the grocery store in one or two-pound boxes, but you’ll likely need to cut the pre-cut cubes in half.

You’ll need a melted fat to cook the squash. If you are on a dairy-free diet, use melted coconut oil or another liquid fat. You can use melted butter or ghee if you can tolerate dairy.

Ground cinnamon, salt and pepper complement the squash perfectly. Leave out the cinnamon if you don’t have it or don’t like it. You can also use a sparkling of garlic powder if you love garlic.

Recipe Steps

Step One

The easiest and fastest way to make this recipe is to start with pre-cubed butternut squash. You can use 1-2 pounds depending on how big your air-fryer is.

If you buy pre-cubed squash, make sure the pieces aren’t large than an inch. If you start with a whole butternut squash, then you will need to peel it using a vegetable peeler, cut it in half, remove the seeds, and then chop up the squash (see this butternut squash tutorial).

Next, place the cubed squash pieces in a large bowl and toss them with coconut oil, salt, pepper, and ground cinnamon.

Step Two

Put the butternut squash cubes in a single layer in the basket of your air fryer, and set the temperature to 390 degrees F for 30 minutes.

If you are using a regular oven, then place your cubes on a baking sheet and bake for 45 minutes at 425 degrees F.

Step Three

Once your squash is fully cooked, the cubes will be slightly browned. You can sprinkle a pinch of salt and pepper on top and serve them warm.

Recipe FAQs

Can I bake these in a regular oven instead of an air fryer?

Yes! You can make roasted squash cubes in an oven. Set the temperature to 425 degrees F for about 45 minutes, tossing once during the cooking process.

Can I cook a whole butternut squash in the air fryer?

Yes, but you’ll need to slice it in half first and scoop out the seeds. See my recipe for Air Fryer Acorn Squash to see the method for cooking a halved squash.

What can I do with roasted butternut squash?

It can be served as a simple side dish. Or, you can blend it in to a 3-ingredient butternut squash soup!

Can I add brown sugar to the squash?

Yes, but I find that butternut squash is usually naturally sweet enough that it doesn’t need any added sugar. That said, you can add up to 2 tablespoons of brown sugar or coconut sugar to the squash before you cook it to add even more of a sweet flavor. You could also just drizzle on some maple syrup before serving.
