Gluten-Free Fried Onion Topping

This is a delicious, gluten-free onion topping for casseroles or even to top a hamburger. They are “oven fried” and are similar to the popular fried-onions-in-a-can that are often used in the traditional green been-bean casserole. This will be a great Thanksgiving meal addition. Enjoy!
