Ingredients

• 4 large yellow onions
• 3 tablespoons unsalted butter
• 1 tablespoon olive oil
• 1 cup heavy cream
• 1.5 cups shredded Gruyere cheese
• 0.5 cup grated Parmesan cheese
• 0.75 cup breadcrumbs
• 2 tablespoons fresh parsley (chopped)
• 0.5 teaspoon garlic powder
• 1 teaspoon salt
• 0.5 teaspoon black pepper

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a medium-sized baking dish with butter or non-stick cooking spray.

Step 2

Peel and thinly slice the yellow onions into half-moon shapes.

Step 3

Heat a large skillet over medium heat. Add the unsalted butter and olive oil, allowing the butter to melt completely.

Step 4

Add the sliced onions to the skillet and cook for 20-25 minutes, stirring occasionally, until the onions are golden brown and caramelized. Lower the heat if necessary to prevent burning.

Step 5

Transfer the caramelized onions to the greased baking dish, spreading them out evenly.

Step 6

In a small saucepan over low heat, warm the heavy cream gently, then stir in 1 cup of the shredded Gruyere cheese, garlic powder, salt, and black pepper. Stir until the cheese is melted and the mixture is smooth.

Step 7

Pour the cheese and cream mixture over the onions in the baking dish, ensuring the onions are evenly coated.

Step 8

In a mixing bowl, combine the breadcrumbs, remaining 0.5 cups of Gruyere cheese, grated Parmesan cheese, and chopped parsley.

Step 9

Sprinkle the breadcrumb mixture evenly over the onions and cheese in the baking dish to form a topping.

Step 10

Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the top is golden brown and bubbling.

Step 11

Remove the onion bake from the oven and let it rest for 5 minutes before serving. Garnish with additional parsley if desired.
