Recipe Information
Ingredients
- 4 units large yellow onions
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 teaspoon fresh thyme leaves
- 2 units garlic cloves, minced
- 0.25 cup dry white wine
- 0.5 cup panko bread crumbs
- 0.25 cup Parmesan cheese, grated
- 0.5 teaspoon kosher salt
- 0.25 teaspoon ground black pepper
- 1 tablespoon fresh parsley, chopped
Instructions
Preheat your oven to 375°F (190°C).
Cut each onion in half lengthwise, keeping the root intact to hold the layers together. Peel off the outer skin and trim the stem end slightly.
Using a small knife, carefully hollow out the center of each onion, leaving about three layers intact along the edges. Finely chop the removed onion centers and set them aside.
In a large skillet over medium heat, melt the butter with the olive oil. Add the chopped onion centers and cook for 5-7 minutes until softened and starting to caramelize.
Add the garlic and thyme to the skillet, cooking for an additional minute until fragrant. Stir in the white wine and cook until the liquid is almost fully evaporated.
Season the mixture with salt and pepper. Remove from heat and fold in the panko bread crumbs and half of the Parmesan cheese.
Place the hollowed-out onion halves on a baking sheet, cut-side up, and season them lightly with salt and pepper.
Fill each onion half with the bread crumb mixture, pressing gently to pack it in.
Sprinkle the remaining Parmesan cheese on top of each filled onion.
Bake the onions in the preheated oven for 40-45 minutes, or until the onions are tender and the tops are golden brown.
Garnish with chopped parsley before serving warm.
