Preparation Time:
- Prep Time: 20 minutes
- Cook Time: 45 minutes
- Total Time: 1 hour 5 minutes
Servings: 6-8 portions
Ingredients:
- 4 large sweet onions (such as Vidalia), thinly sliced
- 3 tablespoons unsalted butter
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon thyme (dried or fresh)
- 1/2 cup sour cream
- 1/2 cup mayonnaise
- 1 cup shredded sharp cheddar cheese
- 1/2 cup grated Parmesan cheese
- 1 cup crushed butter crackers (like Ritz)
- 2 tablespoons melted butter
Instructions:
1. Prepare the Onions:
In a large skillet over medium heat, melt the butter. Add the sliced onions and cook them slowly, stirring occasionally, until they become soft and golden brown—about 15-20 minutes. This step is essential to bring out the sweetness in the onions. Season with salt, pepper, garlic powder, and thyme during the last few minutes of cooking.
2. Mix the Base:
Preheat your oven to 350°F (175°C). In a large mixing bowl, combine the cooked onions with sour cream, mayonnaise, cheddar cheese, and half of the Parmesan cheese. Stir until well blended.
3. Assemble the Casserole:
Transfer the onion mixture to a greased 2-quart baking dish. Smooth the top evenly. In a small bowl, mix the crushed crackers with melted butter, then sprinkle the mixture over the onion base. Top with the remaining Parmesan cheese.
4. Bake:
Place the casserole in the preheated oven and bake uncovered for about 25 minutes, or until the top is golden and bubbly. Let it cool for a few minutes before serving to allow the flavors to set.
