Why you’ll love this recipe

• Fast and simple. Air frying butternut squash takes about 20 minutes and gives the same roasted flavor and texture as the oven, but much faster.
• Great texture. A mix of garlic and onion powder plus smoked paprika produces tender, sweet centers and crisp, caramelized edges.
• Nutritious. Butternut squash is rich in vitamins A and C, fiber and minerals. This recipe uses minimal oil for a lighter side dish.
• Customizable. Swap spices to make it sweet (cinnamon + brown sugar), savory (Italian herbs), or spicy (chili powder or cayenne).

Key ingredients

• Cubed butternut squash — cut yourself or buy pre-cut. Aim for pieces around ¾–1 inch; don’t cut them too small because squash shrinks while cooking.
• Smoked paprika — adds a warm, smoky balance to the squash’s natural sweetness.
• Garlic and onion powder — an easy way to add depth of flavor without extra work.
• Oil, salt and pepper — a tablespoon of oil helps the spices stick and encourages browning; season to taste.

How to cut a butternut squash

• Tools: cutting board, vegetable peeler, sharp knife and a spoon.
• Rinse and dry the squash to remove dirt. Trim off both ends.
• Peel the tough skin with a vegetable peeler.
• Cut where the neck meets the round bottom, then halve each section lengthwise.
• Scoop out seeds from the rounded section with a spoon.
• Cut the halves into ¾–1 inch cubes. Larger pieces retain texture and won’t overcook.

How to make air fryer butternut squash

• Preheat the air fryer to 400°F (204°C).
• In a large bowl, combine 4 cups cubed butternut squash, 1 tablespoon oil, ½ teaspoon garlic powder, ½ teaspoon onion powder, ½ teaspoon smoked paprika, ¼ teaspoon salt and ¼ teaspoon black pepper. Toss until evenly coated.
• Arrange squash in a single layer in the air fryer basket. Avoid overcrowding so pieces roast instead of steam.
• Cook 18–22 minutes, shaking the basket a couple of times during cooking for even browning. Start checking for tenderness at 15 minutes; a fork should pierce easily.
• Optional: spray a light mist of oil with about 7–8 minutes left and shake again for extra crisping.
• When tender, remove carefully, taste and adjust seasoning. Garnish with chopped fresh parsley if desired and serve.

Tips

• Don’t overcrowd the basket. Cook in batches if needed so pieces crisp instead of steaming.
• Expect shrinkage. Four cups raw will yield roughly 2½–3 cups cooked.
• Adjust seasonings. Make it sweet, savory or spicy to match your meal.
• Storage: Refrigerate leftovers in an airtight container up to 4 days.
• Reheat: Warm in the air fryer for a few minutes to refresh crisp edges, or use the microwave for convenience.
