Ingredients You’ll Need
Serves 6–8
For the Dish:
- 4 large sweet onions (Vidalia or Walla Walla work best), thinly sliced
- 2 tbsp unsalted butter
- 2 tbsp olive oil
- 1 tsp sugar (optional, to enhance caramelization)
- Salt and pepper , to taste
- 1 cup heavy cream
- 1 cup shredded cheddar cheese
- 1/2 cup grated Parmesan cheese
- 1/4 tsp garlic powder (optional, for extra flavor)
Optional Toppings:
- Crumbled cooked bacon
- Chopped fresh parsley
- Extra shredded cheese
Step-by-Step Instructions
Step 1: Preheat the Oven
- Preheat your oven to 375°F (190°C) . Lightly grease a baking dish (about 8×8 inches or similar size).
Step 2: Caramelize the Onions
- In a large skillet over medium heat, melt the butter with the olive oil. Add the sliced onions and cook, stirring occasionally, for 15–20 minutes , until they soften and turn golden brown.
- Sprinkle the sugar over the onions during the last 5 minutes of cooking to enhance caramelization. Season with salt and pepper to taste.
Step 3: Assemble the Dish
- Spread the caramelized onions evenly in the prepared baking dish.
- Pour the heavy cream over the onions, ensuring they’re evenly coated.
- Sprinkle the shredded cheddar cheese and Parmesan cheese over the top. Add garlic powder, if using, for an extra layer of flavor.
Step 4: Bake
- Bake for 25–30 minutes , or until the cheese is melted, bubbly, and lightly golden on top. If you’d like a deeper golden crust, broil for 2–3 minutes at the end (watch closely to avoid burning).
Step 5: Garnish and Serve
- Remove from the oven and let cool slightly. Garnish with optional toppings like crumbled bacon or chopped parsley for added flair.
- Serve warm as a side dish or snack, and enjoy the cheesy, caramelized goodness!
