Buttery, sweet, tender, and beautifully caramelized, this Air Fryer Acorn Squash is one of the easiest ways to turn a simple winter squash into an irresistible side dish.
The air fryer works wonderfully for acorn squash because it cooks the squash until the flesh is tender while helping the edges develop delicious golden-brown, caramelized spots. A simple topping of butter and brown sugar melts into the squash, creating a sweet, rich flavor that makes even squash skeptics reach for another serving.
And the best part? You can easily change the seasonings depending on whether you want your acorn squash sweet, savory, or somewhere in between.

How to Make Air Fryer Acorn Squash
1. Prepare the Acorn Squash
Wash the acorn squash thoroughly and dry them.
Using a sharp chef’s knife, carefully cut each squash in half from stem to tip. If the squash is particularly difficult to cut, microwave it for about 1–2 minutes first to soften the skin slightly.
Use a spoon to scoop out the seeds and stringy fibers from the center.
You can save the seeds for roasting if you’d like!
2. Season the Squash
Brush the cut sides of the squash lightly with olive oil or melted butter.
Season with salt and black pepper.
For this recipe, place the squash cut-side down in the air fryer basket.
3. Air Fry
Preheat your air fryer to 375°F (190°C) if your model requires preheating.
Air fry the squash cut-side down for approximately 15–20 minutes, depending on the size of the squash.
The squash should be starting to become tender.
4. Add the Brown Sugar Butter
While the squash cooks, combine the melted butter, brown sugar, cinnamon, and salt in a small bowl.
Carefully turn the squash over so the cut side is facing upward.
Brush the brown sugar butter generously over the flesh.
If you’re using maple syrup, stir it into the butter mixture before brushing it onto the squash.
5. Finish Cooking
Return the squash to the air fryer and cook for another 5–10 minutes, or until the flesh is completely tender and the topping is melted and caramelized.
The exact cooking time will depend on the size and thickness of your squash.
To test for doneness, insert a fork into the thickest part of the flesh. It should slide in easily.
6. Serve
Let the squash cool for a couple of minutes before serving.
Spoon some of the buttery caramelized topping over the squash and serve warm.
Sweet Seasoning Variations
The brown sugar and cinnamon combination is delicious, but don’t be afraid to experiment.
Maple Cinnamon
Replace part of the brown sugar with maple syrup for a deeper, maple flavor.
Brown Sugar & Nutmeg
Add a small pinch of nutmeg to the butter mixture for a warm, classic fall flavor.
Honey Butter
Replace the brown sugar with honey and add a pinch of cinnamon.
Cinnamon Sugar
For an extra-simple version, brush the squash with butter and sprinkle with cinnamon sugar before finishing it in the air fryer.
Savory Acorn Squash
Acorn squash doesn’t have to be sweet!
Skip the brown sugar and cinnamon and try:
- Garlic powder
- Onion powder
- Fresh rosemary
- Fresh thyme
- Smoked paprika
- Parmesan cheese
- Black pepper
- A little chili powder
For a savory version, brush the squash with olive oil or butter and season generously before air frying.
Tips for Perfect Air Fryer Acorn Squash
Choose squash that feels heavy for its size. A good acorn squash should feel firm and have smooth, unblemished skin.
Be careful when cutting. Acorn squash can be surprisingly tough. Use a sturdy, sharp knife and keep your hands away from the blade.
Don’t overcrowd the air fryer. The squash halves should have enough room for the hot air to circulate.
Cooking time varies. Smaller squash halves may cook much faster than large ones, so start checking them early.
Don’t throw away the seeds! Clean them, dry them thoroughly, season them, and roast them for a crunchy snack.
Can You Eat the Skin?
Yes! Acorn squash skin is edible and becomes softer as it cooks. Whether you enjoy it or not is completely up to you.
For the easiest serving option, simply scoop the tender flesh from the skin with a spoon.
What to Serve With Air Fryer Acorn Squash
This squash makes a wonderful side dish for fall and winter meals.
Try serving it alongside:
- Roast chicken
- Turkey
- Pork chops
- Glazed ham
- Steak
- Meatloaf
- Roasted vegetables
- Green beans
- Mashed potatoes
- Wild rice
- A hearty grain salad
It also makes a lovely vegetarian main dish when paired with grains, beans, nuts, or a fresh salad.
Storage and Reheating
Store leftover cooked squash in an airtight container in the refrigerator for up to 4 days.
To reheat, place the squash in the air fryer at 350°F (175°C) for several minutes until warmed through.
The air fryer is preferable to the microwave when you want to bring back some of the caramelized texture.
