Air Fryer Butternut Squash

Air Fryer Butternut Squash

Butternut squash cooks fast and evenly in an air fryer, turning tender in the centre with caramelized, golden edges in well under half an hour. Cut the squash into even 1.5 cm cubes, toss with a little oil, salt, and pepper, and let the machine do the rest.

From there the dish splits in two directions. Go sweet with cinnamon and a finish of maple syrup, or go savory with garlic powder, onion powder, paprika, and a pinch of cayenne. Both start from the same base and the same technique — only the seasoning changes.

This isn’t a recipe with a long history behind it; it’s a modern side dish built around a modern kitchen tool. The squash needs peeling first — the skin stays tough even after air-frying — and a single layer in the basket matters more than anything else. Crowd the basket and the squash steams instead of browning.

Serve it warm alongside roasted meat or a grain bowl, or eat it on its own as a simple vegetable side.

Ingredients

Serves 4

The base

  • 1 medium butternut squash (about 680 g prepped flesh), peeled, seeded, and cut into 1.5 cm cubes
  • 1 tbsp olive oil
  • 3/4-1 tsp kosher salt
  • 1/4 tsp ground black pepper

The sweet finish (choose one style)

  • 1 tbsp pure maple syrup
  • 1/2 tsp ground cinnamon
  • 2 tsp fresh rosemary, chopped (optional garnish)

The savory finish (alternative to sweet)

  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1/2 tsp sweet paprika
  • 1 pinch cayenne pepper (optional)

Directions

The base

Peel the squash with a vegetable peeler, cut it in half lengthwise, and scoop out the seeds with a spoon. Cut the flesh into even cubes about 1.5 cm (1 inch) across — uniform pieces cook at the same rate, so take a moment to keep them consistent.

Toss the cubes in a bowl with the olive oil, salt, and pepper. If you’re going sweet, stir in the cinnamon at this point too, so it coats the squash before cooking.

Spread the cubes in a single layer in the air-fryer basket, without crowding — work in two batches if your basket is small, since crowded cubes steam rather than brown. Air-fry at 375°F (190°C).

After 10 minutes, pull out the basket and shake or toss the cubes. Put it back in and cook another 8 to 12 minutes — 18 to 22 minutes total — tossing once or twice more, until the squash is fork-tender inside and caramelized at the edges. For a gentler cook, use 340–356°F (170–180°C) instead and expect 20 to 25 minutes total; the lower the temperature, the longer it takes to brown.

To finish

For the sweet version, tip the cooked squash back into the bowl and toss with the maple syrup, adding the rosemary if using, then taste and add a little more salt if needed. For the savory version, toss the spice blend — garlic powder, onion powder, paprika, and cayenne — through the cubes either at the 10-minute shake or once cooking is done, then return the basket to the air fryer for 3 to 4 minutes to set the spices.

Serve warm.

Notes

Pre-cut squash from the store saves prep time, but the pieces are often larger and less even, so add a few minutes and expect less uniform browning.

For extra-crisp edges, avoid crowding the basket and finish with a minute or two under the broiler.

Refrigerate leftovers up to 5 days, or freeze up to 3 months.
