Why Choose Butternut Squash in the Air Fryer?

Before diving into the recipe, it’s helpful to understand why the air fryer is such a fantastic option for cooking whole butternut squash:

Time-Saving: Unlike conventional ovens, air fryers preheat in just a few minutes and cook more efficiently thanks to rapid air circulation.
Even Roasting: The air fryer creates a beautifully roasted outer layer while keeping the inside soft and rich.
Oil-Free or Low-Oil Option: Butternut squash has a naturally creamy and slightly oily texture, so minimal or no added oil is required.
Flavor Concentration: The circulating hot air intensifies the squash’s sweetness, creating a rich, caramelized flavor.
Less Cleanup: Cooking in the air fryer reduces mess and cleanup time significantly.

Ingredients and Equipment

Ingredients:

1 whole medium butternut squash (around 2 to 3 pounds)
1 tablespoon olive oil (optional)
Salt and pepper to taste (optional)
Optional flavor add-ins: ground cinnamon, smoked paprika, garlic powder, rosemary, or maple syrup (based on desired use)

Equipment:

Air Fryer (recommended basket size: at least 6 quarts)
Sharp chef’s knife
Cutting board
Spoon (for scooping seeds)
Tongs
Kitchen brush (for applying oil if used)

Step-by-Step Recipe: Air Fryer Whole Butternut Squash

Step 1: Choosing the Right Squash

Look for a firm, evenly colored butternut squash with a matte finish. Avoid any with soft spots, cracks, or mold. A medium-sized squash (2–3 pounds) typically fits into most large air fryer baskets.

Step 2: Clean the Squash

Wash the skin thoroughly under running water to remove dirt or residues. Since we’ll be cooking it with the skin on, this step is important.

Dry the squash with a kitchen towel.

Step 3: Poke Holes for Steam Release

Use a fork or small paring knife to poke several holes all around the squash, especially the bulbous end. This step prevents the squash from bursting in the air fryer as steam builds up inside.

Pro Tip: If you prefer a slightly softer, steamed interior, poke fewer holes. For a drier, more roasted texture, poke more.

Step 4: Air Fry the Whole Squash (First Roast)

Place the whole butternut squash directly in the air fryer basket.

Temperature: 375°F (190°C)
Time: 30 minutes

After the first 30 minutes, check the squash using tongs. If it has started to soften and slightly brown, it’s time to move to the next step.

Step 5: Cut and Clean

Carefully remove the hot squash using tongs or oven mitts and place it on a cutting board. Let it cool for about 5–10 minutes.

Then:

Slice the squash in half lengthwise.
Use a spoon to scoop out the seeds and discard them or set them aside for roasting later.
Optional: Brush the exposed flesh with olive oil and sprinkle with salt, pepper, or desired spices.

Step 6: Air Fry Flesh Side Down (Second Roast)

Return the squash halves, flesh side down, into the air fryer basket.

Temperature: 375°F (190°C)
Time: 15–20 minutes

Check for doneness by piercing the thickest part with a fork—it should slide in effortlessly, and the flesh should be golden and caramelized.

Step 7: Serve or Store

Remove the squash from the air fryer. Allow it to cool slightly before serving.

You can:

Scoop out the flesh and mash it for a side dish.
Cube it for salads or bowls.
Blend it into soups or sauces.
Stuff the halves for a gourmet presentation.

Flavor Variations & Serving Ideas

The beauty of roasted butternut squash lies in its versatility. Here are some ways to elevate the dish:

1. Sweet Variation (Dessert-Style)

After the first roast, brush the inside with melted butter, sprinkle brown sugar, cinnamon, and a touch of maple syrup.
Air fry face down again as instructed.

2. Savory & Herb-Infused

Brush with olive oil and sprinkle rosemary, thyme, garlic powder, and a pinch of smoked paprika.

3. Parmesan Crusted

After the first roast, sprinkle grated Parmesan cheese on the flesh, then roast face up for the second round to create a crispy cheesy crust.

4. Stuffed Butternut Squash

Use the halves as edible bowls and fill them with:

Quinoa, spinach, and chickpeas
Wild rice with cranberries and nuts
Ground sausage and kale
Couscous, roasted peppers, and feta

Tips for Best Results

Don’t overcrowd the air fryer basket. Cook only one squash at a time to ensure even roasting.
If your squash is too large, you can cut off the bulb and cook the neck and bulb separately.
For a softer texture, lower the air fryer temperature to 350°F and increase the time slightly.
If you’re short on time, consider microwaving the whole squash for 3–4 minutes before air frying—it softens the flesh and reduces cooking time.

Storage and Reheating

Storing Leftovers:

Let the cooked squash cool completely.
Scoop the flesh into an airtight container.
Store in the refrigerator for up to 5 days.
Freeze for up to 3 months (best if mashed or pureed first).

Reheating Tips:

Reheat in the air fryer at 350°F (175°C) for 5–7 minutes.
Or microwave on medium power for 1–2 minutes.
