Our air fryer acorn squash recipe is an easy Fall dish that’s ready in under 20 minutes. It’s roasted to perfection and seasoned with balsamic vinegar and sprinkled with feta cheese. 

Now that we are officially in the Fall season, I’ve been experimenting with squash recipes. In case you missed it, I have already mastered spaghetti squash in the air fryer. So I thought I would try acorn squash next.

If you haven’t had much experience with this type of squash, it has a slightly sweet and naturally nutty flavor, especially when compared to butternut squash. While you can make a sweet version, I really enjoy a savory flavor profile because it complements cold weather meals. 

How to Choose Acorn Squash 

When shopping the produce section, ripe acorn squash will be dark green and the stem will be dry. You’ll also want the skin to be firm. As always, steer clear of squash with bruises, mold, or blemishes.

You may also notice that when you pick it up, it feels heavy for the size. 

Unlike other popular produce items, acorn squash stored in a cool dry place can stay fresh for 1 to 2 months. If you cut into it and it’s a little slimy or the seeds have a gray tint, you’ll want to toss it in the trash. These are indicators that it has spoiled.

How to Make Air Fryer Acorn Squash

Dip each slice into the balsamic mixture and turn to coat completely. 

Spray the air fryer basket with oil (I use this refillable oil mister). Add the squash and cook for 6 minutes. Turn the slices and cook for an additional 6 minutes.

How to Make Oven Baked Acorn Squash 

Line a baking sheet with parchment paper. Follow the instructions above for cutting and dipping in seasoning mix.

Place the squash slices on the sheet pan and bake for 25 minutes at 375 degrees F. Flip each slice and continue cooking for another 15 or 20 minutes until tender. 


Tips for Making


  • When cutting the acorn squash make sure you use a knife that is heavy and sharp.
  • To save time you can check the produce section for pre-sliced acorn squash.
  • If desired, drizzle with maple syrup instead of honey.
  • Instead of greasing the basket you can use a parchment paper liner.
  • For a sweet version, use butter cinnamon, and sugar in place of the balsamic and feta.

Can You Eat the Skin of Acorn Squash? 

Sometimes the skin on these squash is described as being tough. When air frying, it does get tender so it’s really a personal preference when making this recipe. Once it’s cooked, it’s really easy to peel the skin off if you don’t want to eat it. 

Can You Cook Whole Acorn Squash in the Air Fryer? 

Sure can! This is perfect when you want to make soup or mash it up. Simply slice it in half (scoop out the insides) and place it face down in the basket. Air fry for 20 minutes at 400 degrees F until it’s fork tender. 

Before adding it to soup, let it cool slightly. You can then mash it by hand or use an immersion blender

How to Store 

Keep leftovers in an airtight container for 3 to 4 days in the refrigerator. Reheat in the air fryer for 3 to 5 minutes at 375 degrees F.
