Preheat the air fryer (5 min): Set your air fryer to 375°F and let it preheat while you prep the squash. This helps everything crisp up right away.
Prep the squash (5 min): Use a vegetable peeler to remove the skin, then cut the squash in half lengthwise. Scoop out the seeds, and dice the flesh into even 1-inch cubes.
1 medium butternut squash
Season the squash (2 min): In a large mixing bowl, combine the diced squash with olive oil, maple syrup, garlic powder, paprika, salt, and optional cinnamon. Toss well until every piece is coated.
1 Tablespoon olive oil, 1-2 Tablespoons maple syrup, 1 teaspoon garlic powder, 1/2 teaspoon paprika, 1 teaspoon kosher salt, 1/2 teaspoon cinnamon
Air fry the squash (20 min): Spread the squash in a single layer in the air fryer basket. Avoid overcrowding—cook in batches if needed. Air fry for 10 minutes, then shake the basket and cook another 8–10 minutes, or until the edges are golden brown and the centers are fork-tender. Finish with the broil setting for 1-2 minutes if your air fryer has the setting.
Serve and enjoy: Serve warm as a side dish or let cool and store for meal prep. It pairs perfectly with grilled chicken, fall salads, or a cozy Thanksgiving spread.
