Cut acorn squash in half then spray it with olive oil spray and dust salt/pepper.
Place squash halves open side up in your air fryer.
Air fry for 25 mins at 300F. (Or broil in oven)
Let squash cool then spoon out the flesh into your food processor.
Add all ingredients to the food processor along with the squash.
Process until well combined. If you want a thinner sauce, add more milk/water!
