• In a large mixing bowl, toss up the butternut squash cubes along with olive oil, maple syrup, and cinnamon.
• Preheat your air fryer (I used my Instant Vortex) at 370 F (190 C).
• Once preheated, add the seasoned cubes of butternut squash in a single layer without crowding.
• Cook at 370 F for 10 minutes, flipping once midway. Add the salt mid-way through, toss and continue to air fry until the 10 minutes cycle is complete.
• Take out the cooked squash and garnish with chopped-up parsley (optional). Air Fryer butternut squash is now ready to be served.

Alternative method - in the oven

• Follow the same steps as above to season the butternut squash cubes in a mixing bowl.
• Then transfer the butternut squash to a baking tray, in a single layer.
• Bake the squash at 400 degrees for 20 minutes, until caramelized and cooked. Season with salt and serve.
