Crispy Roasted Butternut Squash in the Air Fryer

The most delicious, savory air fryer butternut squash — a quick, healthy side dish that’s tender, flavorful, and a perfect addition to your favorite butternut squash recipes.

Air Fryer Butternut Squash

I kept getting asked, “Is butternut squash good in the air fryer?” After testing different temperatures and timings, I landed on this simple method that delivers tender, slightly caramelized cubes every time. This sweet-and-savory winter squash pairs beautifully with roasted chicken, baked pork chops, turkey breast, or can be folded into salads, bowls, and breakfast dishes. It’s gluten-free, dairy-free, vegan, high in fiber, and low in calories — a reliable side that’s both healthy and crowd-pleasing.

A Quicker Way to Cook Butternut Squash

Air frying cuts cooking time compared to the oven and avoids heating up your kitchen. If you want to save even more time, use pre-cut butternut squash. If you prefer to cut and peel your own, use a sharp peeler and a sturdy chef’s knife and cut into roughly 1-inch cubes for even cooking.

Ingredients

These quantities yield about 4 cups of diced squash (roughly 24 ounces), serving four.

• Butternut squash: 4 heaping cups peeled and diced into 1-inch cubes (about 24 ounces)
• Olive oil: 1 tablespoon plus spray for the basket
• Onion powder: 1 1/2 teaspoons
• Garlic powder: 1 1/2 teaspoons
• Sweet paprika: 1/2 teaspoon
• Cayenne pepper: 1/8 teaspoon (optional — omit if you prefer no heat)
• Kosher salt: 1/2 teaspoon
• Brown sugar: 1 teaspoon (optional, adds a touch of caramelized sweetness)

How to Make Butternut Squash in the Air Fryer

1. Preheat the air fryer to 340°F (170°C) if your model requires preheating.
2. Place the diced squash in a single layer in the air fryer basket. A little overlap is fine, but avoid overcrowding for best browning. Lightly spray the squash with olive oil spray.
3. Air fry for about 20–23 minutes at 340°F, shaking the basket a few times during cooking so the pieces brown evenly and become fork-tender.
4. While the squash cooks, mix the onion powder, garlic powder, sweet paprika, cayenne, salt, and brown sugar (if using) in a small bowl.
5. When the squash is tender, transfer it to a bowl, drizzle with 1 tablespoon olive oil, and toss gently to coat.
6. Add the spice mixture and toss lightly so each cube is evenly seasoned.
7. Return the spiced squash to the air fryer for 3–4 more minutes to set the seasoning and develop a bit more color. Serve hot.

Do I need to peel butternut squash before roasting?

Yes. If you’re cutting the squash into cubes, peel it first with a vegetable peeler or a sharp knife. Using pre-cut squash saves time and is an excellent shortcut.

What to Serve with Air Fryer Butternut Squash

This squash is versatile and works well as a side, topping, or component in many meals. Ideas:

• Add to scrambled eggs or a breakfast bowl for a savory-sweet morning boost.
• Serve alongside roasted chicken, baked pork chops, turkey breast, or grilled fish.
• Use in meal-prep bowls with a lean protein (like chicken breast) and a green vegetable such as broccoli or Brussels sprouts.
• Place warm squash over mixed greens with nuts and dried fruit to create a harvest-style salad.

Tips and Variations

• For a sweeter profile, swap brown sugar for a drizzle of maple syrup before adding spices.
• Try cinnamon or pumpkin pie spice with a pinch of salt for a fall-inspired twist.
• If you dislike heat, simply omit the cayenne pepper.
• Pre-cut squash pieces can be larger and may require a few extra minutes in the air fryer — test for tenderness with a fork.
• For crispier edges, give the squash a light spray of oil halfway through cooking and increase the last 3–4 minutes to a slightly higher temperature if your air fryer allows.

Storage and Reheating

Store cooled squash in an airtight container in the refrigerator for up to 4 days. Reheat in the air fryer at 325°F for 4–6 minutes to revive a bit of crispness, or warm gently in the oven. You can also reheat in the microwave, though it will be softer.
