Cheesy Baked Onion Stacks Recipe

by

These cheesy baked onion stacks are a delightful appetizer or side dish. Sweet onions are layered with cheese, breadcrumbs, and herbs, then baked until tender and golden. They’re easy to make and perfect for any occasion.  

Ingredients:

  • 2 large sweet onions (such as Vidalia or Walla Walla)  
  • 1 cup shredded cheese (cheddar, mozzarella, Gruyère, or a blend)
  • 1/2 cup breadcrumbs (plain or panko)  
  • 2 tablespoons olive oil
  • 1 tablespoon fresh thyme leaves (or 1 teaspoon dried thyme)
  • 1 tablespoon fresh parsley, chopped
  • 1/2 teaspoon garlic powder
  • Salt and pepper to taste
  • Optional: a pinch of red pepper flakes for heat

Instructions:

  1. Prepare the Onions:
    • Preheat your oven to 375°F (190°C).
    • Peel the onions and cut them in half through the root.
    • Carefully separate the layers of each onion half, keeping the layers intact as much as possible.
  2. Combine the Filling:
    • In a medium bowl, combine the shredded cheese, breadcrumbs, olive oil, thyme, parsley, garlic powder, salt, pepper, and red pepper flakes (if using). Mix well.
  3. Assemble the Stacks:
    • Take a large onion layer and place a spoonful of the cheese mixture inside.
    • Place another layer on top and add more cheese mixture.
    • Continue layering until you have a stack about 2-3 inches high.
    • Repeat the process with the rest of the onion layers and cheese mixture.
    • If you have very small onion layers, they can be added to the larger stacks.
    • If you have a few breadcrumb cheese mixture left over, you can sprinkle it over the tops of the stacks.
  4. Bake the Stacks:
    • Place the onion stacks in a baking dish.
    • Bake for 30-40 minutes, or until the onions are tender and the cheese is melted and golden brown.
    • If the tops are not golden enough, you can broil them for the last two minutes of baking. Watch them closely so they do not burn.
  5. Serve:
    • Let the onion stacks cool slightly before serving.
    • Serve warm as an appetizer or side dish.

Tips and Variations:

  • For a richer flavor, use a combination of cheeses.
  • Add cooked crumbled bacon or sausage to the cheese mixture.
  • Drizzle with balsamic glaze before serving.
  • For a sharper flavor, add a small amount of dijon mustard to the cheese mixture.
  • Using a muffin tin can help keep the stacks from falling over.
