Step 1: Prepare the Onions
Preheat your oven to 375°F (190°C).
Peel the onions and slice them into thick rounds (about ½-inch thick). Try to keep the slices uniform so they cook evenly.
Lightly grease a baking dish with butter or cooking spray.
Step 2: Layer the Onions
Arrange the onion slices in the baking dish in a single layer. It’s okay if they slightly overlap, but avoid stacking them too thickly.
Sprinkle the onions evenly with:
-
Salt
-
Black pepper
-
Garlic powder
-
Dried thyme
Dot the butter cubes evenly over the onions. This butter will melt down and create the rich base of the dish.
Step 3: Add the Cheese 🧀
In a bowl, mix together:
-
Cheddar cheese
-
Mozzarella cheese
-
Parmesan cheese
Sprinkle the cheese mixture generously over the onions, covering them completely.
This combination gives you:
-
Sharp flavor from cheddar
-
Stretchy melt from mozzarella
-
Nutty depth from Parmesan
Step 4: Bake to Perfection
Cover the baking dish loosely with aluminum foil and bake for 30 minutes.
After 30 minutes, remove the foil and continue baking for another 20–25 minutes, or until:
-
The onions are fork-tender
-
The cheese is bubbly and golden on top
If you want extra browning, you can broil the dish for 2–3 minutes at the end—just keep an eye on it!
