Air Fryer Butternut Squash

Butternut squash is a versatile vegetable, offering a sweet and slightly nutty flavor that complements both savory and sweet dishes. When cooked in an air fryer, just like a ventilated oven, it develops a crispy exterior while maintaining its tender, flavorful interior, making it the perfect side for any meal or a nutritious snack on its own.

Using an air fryer also means a healthier option with less oil than traditional roasting, and it cuts down the cooking time without compromising flavor. Plus, the convenience of minimal cleanup is always a win! This method locks in the squash's natural sweetness and allows for a crispy texture that's hard to resist. If you're short on time or just love easy, healthy recipes, this one will quickly become a favorite.

🧾 Ingredients

• Butternut Squash: Look for a firm, medium-sized butternut squash with a smooth skin. Avoid any that have soft spots or bruises. You'll want about 1½ pounds for this recipe, which will give you around 3-4 servings.
• Olive Oil: A little bit goes a long way to help crisp up the squash in the air fryer. You can also use avocado oil or another high-smoke-point oil. Around 1-2 tablespoons will be enough. You can brush a thin layer or spray it.
• Salt: Enhances the natural sweetness of the butternut squash. Use sea salt or kosher salt for a more subtle taste.
• Seasonings: Garlic powder, sage, red chilli pepper flakes, rosemary, and thyme pair beautifully with butternut squash.

🍳 Substitutions

• Butternut Squash: You can substitute it with acorn squash, kabocha squash, or even sweet potatoes. These vegetables will have a similar texture and flavor profile when air-fried.
• Olive Oil: Swap with avocado oil, grapeseed oil, or coconut oil. Each will give a slightly different flavor but still promote crispiness.
• Garlic Powder: If you're out of garlic powder, onion powder or smoked paprika can also add depth to the flavor.
• Fresh Herbs: Dried herbs can work just as well as fresh. If you don't have rosemary or thyme, oregano or basil are great alternatives.

🥣 Variations

• Sweet Butternut Squash: For a sweeter twist, drizzle honey or maple syrup over the squash before cooking. Add a pinch of cinnamon or nutmeg to bring out warm, sweet flavors.
• Spicy Butternut Squash: If you like a bit of heat, toss the squash in chili powder, cayenne, or red pepper flakes before air frying. This variation pairs well with a cooling dip like yogurt sauce or sour cream.
• Parmesan-Crusted Squash: Add freshly grated Parmesan cheese during the last 5 minutes of air frying for a crispy, cheesy topping. This variation adds richness and a touch of savory flavor.
• Butternut Squash Fries: Cut the butternut squash into fry shapes instead of cubes. Season with your favorite spices, and you've got a healthier version of fries in no time!

📋 Instructions with Photos

Step 1. Brush a thin layer of olive oil on the butternut squash slices. Mix the spices in a bowl and sprinkle on both sides, together with salt.

Step 2. Cook in the air fryer for 20-25 minutes or until fork tender, flipping the slices halfway through.

🔪 Equipment

• Air Fryer: The essential tool for this recipe. Look for an air fryer with a basket large enough to hold the squash in a single layer. If your air fryer is smaller, you may need to cook the squash in batches to ensure it crisps up evenly.
• Peeler: A sturdy vegetable peeler will make peeling the tough skin of the butternut squash much easier.
• Sharp Knife: A large, sharp knife is essential for cutting through the firm squash.
• Cutting Board: A stable cutting board will give you the surface you need to peel and chop the squash safely.

❄️ Storage & Reheating

Fridge: Once your butternut squash has cooled, store any leftovers in an airtight container in the fridge for up to 3-4 days. Reheating is easy - simply pop the squash back into the air fryer for 2-3 minutes to regain its crispy texture. Alternatively, you can reheat it in the oven at 375°F (190°C) for about 5-7 minutes.

Freezer: While it's best enjoyed fresh, you can freeze air-fried butternut squash if needed. Let it cool completely, then place it in a single layer on a baking sheet. Freeze until solid (about an hour), then transfer to a freezer-safe bag or container. It will keep for up to 2 months. To reheat, use the air fryer directly from frozen, cooking for 8-10 minutes at 350°F (175°C) or until heated through and crispy again.
