Ingredients
Scale:
4 large sweet onions (such as Vidalia), thinly sliced
1 cup sour cream
1 cup mayonnaise
2 cups shredded cheddar cheese, divided
1 cup crushed buttery crackers (such as Ritz)
1 teaspoon garlic powder
1 teaspoon onion powder
Salt and pepper, to taste
1 cup crushed buttery crackers (for topping)
2 tablespoons butter, melted
Instructions
Preheat the oven: Set your oven to 350°F (175°C) to preheat while you prepare the casserole.
Prepare the onions: In a large skillet over medium heat, add a drizzle of oil and sauté the sliced sweet onions for about 10-12 minutes, until they are soft and translucent.
Mix the base: In a large mixing bowl, combine the sautéed onions, sour cream, mayonnaise, 1 cup of shredded cheddar cheese, garlic powder, onion powder, salt, and pepper. Stir well.
Add the crushed crackers: Gently fold in 1 cup of crushed buttery crackers into the onion mixture.
Transfer to baking dish: Pour the mixture into a greased 9x13-inch baking dish, spreading it evenly.
Prepare the topping: In a small bowl, mix the remaining crushed crackers with the melted butter and sprinkle over the casserole.
Bake: Place the dish in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and the casserole is bubbling.
Cool and serve: Once baked, remove the casserole from the oven and let it cool for about 5-10 minutes before serving.
