Tips & Variations
-
Use sweet onions (Vidalia, Walla Walla) for natural sweetness.
-
For extra flavor, sprinkle red pepper flakes or smoked paprika.
-
Can be served as a side or as a topping for burgers or sandwiches.
-
Make-ahead: slice and season onions in advance; add cheese and bake when ready.
This dish is rich, cheesy, and melts in your mouth, making it a great alternative to traditional fried onion rings.
If you want, I can provide a metric version of this recipe and a lighter cheese or lower-carb version too.
