Serve air fryer acorn squash as a simple side dish as the recipe recommends. Or use this recipe to make mashed acorn squash. It would be superb (with a little ricotta) as a filling for ravioli or another homemade pasta. Another idea: before plating, you can add rice, quinoa, or anything else you’d like inside the hollow part of the cooked squash. That would turn this into a stuffed acorn squash.
