Air fryer brown sugar butternut squash is the perfect fall side dish. The brown sugar gives the butternut squash an extra bit of sweetness and the squash caramelizes beautifully in the air fryer.
Brown sugar butternut squash is so delicious. I made this recipe once, and it was so good, I made it two more times in the same week.
It's just something about the combination of the brown sugar, the butternut squash, and the cayenne pepper. It's that spicy-sweet combo that I just cannot get enough of.
Ingredients
- Butternut squash - You'll need 3 ½ cups of butternut squash cut into cubes about ¾ inch. This is the equivalent of 15 oz. You can either peel and cut the cubes yourself, or buy pre-cut cubes.
- Olive oil - The olive oil will help your butternut squash roast in the air fryer.
- Brown sugar - The brown sugar gives the perfect amount of sweetness to this recipe.
- Smoked paprika - The smoked paprika helps to balance out the sweet and spicy flavors by adding a touch of smoky flavor to the butternut squash.
- Ground cayenne pepper - This adds that nice spiciness to the squash.
- Salt - Salt helps to flavor the dish!

How to customize
- Don't want it spicy? Either use only a pinch of the cayenne pepper, no cayenne pepper, or substitute out chili powder instead.
- For an added boost of savory flavors, add some garlic powder or onion powder.
- Add some ground cinnamon or pumpkin pie spice for extra fall vibes.
How to store leftovers
Cool the butternut squash completely, then store in the refrigerator in an airtight container for up to three days.
To reheat, simply pop back into the air fryer for a few minutes. You can also place on a baking sheet, toss in a bit more olive oil, and roast in the oven at 400 degrees F for 10 minutes until hot.

Recipe tips
- If you are sensitive to spice, either leave out the ground cayenne or just add a small pinch.
- If using precut butternut squash, the sizes may vary. You may need to add or subtract cooking time based on the size of your butternut squash cubes.
