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

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease a 9-inch square or similarly sized casserole dish and set it aside.

Step 2

Peel and thinly slice the Vidalia onions into rings.

Step 3

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.

Step 4

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.

Step 5

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.

Step 6

Pour the onion mixture into the prepared casserole dish. Spread it out evenly.

Step 7

Evenly sprinkle the shredded sharp cheddar cheese over the onion mixture.

Step 8

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.

Step 9

Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and the casserole is bubbling around the edges.

Step 10

Remove from the oven and let it rest for 5-10 minutes before serving. Serve warm.
