How to Make Cheesy Baked Onion Stacks
Step 1: Prepare the Onions
Preheat your oven to 375°F (190°C).
Peel the onions and slice them horizontally into ½-inch thick rings. Carefully separate the rings into individual layers.
Step 2: Season the Onions
Place the onion rings on a baking sheet or in an oven-safe dish.
Drizzle the melted butter and olive oil over the onion slices, ensuring they are evenly coated.
Sprinkle garlic powder, smoked paprika, thyme, salt, and pepper over the onions for a burst of flavor.
Step 3: Stack the Onions
Create stacks by layering onion rings from largest to smallest. Aim for 3-4 layers per stack, pressing down gently to secure them.
Step 4: Add the Cheese
Sprinkle the shredded mozzarella cheese generously over the onion stacks.
Top each stack with a layer of Parmesan cheese for an extra cheesy crust.
Step 5: Bake the Onion Stacks
Cover the baking dish with aluminum foil and bake for 20 minutes.
Remove the foil and bake for another 15-20 minutes, or until the cheese is melted and golden brown.
Step 6: Garnish and Serve
Remove from the oven and let the stacks cool for 5 minutes.
Garnish with fresh parsley before serving.
