Ingredients:
- 3 large sweet onions (such as Vidalia or Walla Walla), sliced into 1/4-inch rings
- 2 cups shredded Gruyère cheese (or cheddar, if preferred)
- 1 cup heavy cream
- 1/2 cup grated Parmesan cheese
- 1/4 cup unsalted butter
- 1 teaspoon garlic powder
- 1/2 teaspoon smoked paprika
- 1 teaspoon fresh thyme leaves (optional)
- Salt and pepper to taste
- Fresh parsley, chopped (for garnish)
- Panko breadcrumbs (optional for extra crunch)
Instructions:
- Preheat the Oven: Preheat your oven to 350°F (175°C).
- Prepare the Onions: Peel and slice the onions into rings about 1/4 inch thick. Separate the rings gently.
- Arrange the Onions: In a greased 9×13-inch baking dish, layer the onion rings evenly.
- Make the Cheese Mixture: In a medium saucepan over medium heat, melt the butter. Stir in the heavy cream, garlic powder, smoked paprika, and thyme (if using). Slowly add the shredded Gruyère cheese, stirring constantly until the cheese is melted and the mixture is smooth. Season with salt and pepper to taste.
- Pour Over the Onions: Pour the creamy cheese mixture over the onions, making sure they are fully coated.
- Top with Parmesan: Sprinkle the grated Parmesan cheese over the top of the onions. If you’d like a bit of extra crunch, you can also sprinkle some panko breadcrumbs on top.
- Bake: Bake in the preheated oven for 25-30 minutes, or until the onions are tender, the cheese is bubbly, and the top is golden brown.
- Garnish and Serve: Remove from the oven and let the dish cool for a few minutes. Garnish with fresh parsley and serve warm as a side dish or even as a delicious main with crusty bread.
Enjoy this Southern-inspired dish that’s cheesy, creamy, and absolutely irresistible!
