🛒 Ingredient notes

Butternut squash – Peel, deseed and cube into roughly 2cm (¾ inch) pieces for even cooking. Other firm squashes can be substituted.

Olive oil – A light coating helps the cubes crisp. Use a tablespoon or swap for a low-calorie cooking spray if preferred.

Dried thyme – Adds an earthy note; rosemary, oregano, smoked paprika or garlic powder are great alternatives.

Salt & pepper – Season to taste; sea salt is recommended for a clean finish.

How to prepare a whole butternut squash for the air fryer

1. Wash and dry the squash. Trim both ends so it sits securely on the board.
2. Peel the skin away with a sharp knife or a sturdy vegetable peeler. The skin can be left on if you prefer, but peeled cubes crisp more reliably.
3. Slice the squash lengthwise and scoop out seeds and fibrous bits from the cavity.
4. Place a half cut-side down and slice into 1.5–2cm (½–1 inch) thick slabs, then stack a few and dice into cubes.
5. Repeat with the remaining half until all the squash is cubed evenly.

🔪 How to cook butternut squash in the air fryer

The recipe card with quantities and step-by-step instructions appears below.

Step 1: Preheat your air fryer to 180°C (350°F).

Step 2: Toss the diced squash in a bowl with olive oil, thyme, salt and pepper until evenly coated.

Step 3: Spread the cubes in a single layer in the air fryer basket and cook for 15–18 minutes, shaking the basket or stirring gently every 5 minutes so pieces brown evenly. Cook until the outsides are golden and the interiors are easily pierced with a knife.

Tip: If your air fryer is small, cook in batches so pieces have space and crisp properly.

🍴 Serving suggestions

Serve air fryer butternut squash alongside roast turkey, chicken, or vegetarian mains. It also makes a tasty addition to grain bowls, warm salads, or as part of a festive plate. For a quick meal, toss the warm cubes with mixed greens, goat’s cheese and a light vinaigrette.

📖 Variations

• Season with smoked paprika and garlic for a spicier profile.
• Drizzle honey over the cubes before cooking for a glazed finish.
• Sprinkle grated Parmesan after cooking for a cheesy topping.
• Swap in sweet potato for a similar texture with different flavour notes.
• Cut into batons and air fry for squash fries—great for dipping.

🥡 Storage

Best served fresh, but leftovers keep in an airtight container in the fridge for up to 3 days. Reheat in the air fryer at 180°C for a few minutes to restore crispness, or warm in the oven. Freezing is not recommended as the texture degrades.

❓ Frequently asked questions
