Recipe Information
Ingredients
- 5 large Vidalia onions
- 4 tablespoons unsalted butter
- 1 cup sour cream
- 1.5 cups shredded sharp cheddar cheese
- 1.5 cups crushed butter crackers (e.g., Ritz)
- 2 large eggs
- 1 teaspoon kosher salt
- 0.5 teaspoons black pepper
- 0.5 teaspoons garlic powder
- 2 tablespoons milk
Instructions
Preheat your oven to 350°F (175°C). Grease a 9-inch square or similarly sized casserole dish and set it aside.
Peel and thinly slice the Vidalia onions into rings.
In a large skillet, melt the butter over medium heat. Add the sliced onions and cook, stirring occasionally, for 10-15 minutes, or until they are soft and beginning to caramelize.
While the onions are cooking, in a large mixing bowl, whisk together the sour cream, eggs, milk, salt, pepper, and garlic powder until well combined.
Once the onions are caramelized, remove the skillet from the heat and let the onions cool slightly. Stir the onions into the sour cream mixture until evenly distributed.
Pour the onion mixture into the prepared casserole dish. Spread it out evenly.
Evenly sprinkle the shredded sharp cheddar cheese over the onion mixture.
In a separate bowl, mix the crushed butter crackers with 2 tablespoons of melted butter (optional) until combined. Spread the cracker mixture evenly on top of the cheese layer.
Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and the casserole is bubbling around the edges.
Remove from the oven and let it rest for 5-10 minutes before serving. Serve warm.
