Make-Ahead Christmas Brunch Casserole Recipe

Ingredients

• 1 pound bacon
• 2 medium onions, chopped
• 2 cups fresh sliced mushrooms
• 1 tablespoon butter
• 4 cups frozen hash brown potatoes, thawed
• 1 teaspoon salt
• 0.5 teaspoon ground black pepper
• 0.25 teaspoon garlic salt
• 4 medium eggs
• 1.5 cups milk
• 1 pinch dried parsley
• 1 cup shredded Cheddar cheese

Instructions

1. Assemble all casserole ingredients.
2. Cook bacon in a large skillet over medium-high heat, flipping occasionally, until crisp and evenly browned, approximately 10 minutes. Move bacon to a paper towel-lined plate to drain and crumble once cooled. Discard bacon grease from the skillet.
3. Sauté onions and mushrooms in the skillet with the remaining bacon grease until onions become translucent and mushrooms are soft, about 5 minutes.
4. Grease a 9x13-inch baking dish with 1 tablespoon of butter. Arrange hash brown potatoes in the bottom of the dish; season with salt, pepper, and garlic salt. Sprinkle with crumbled bacon, followed by the sautéed onions and mushrooms.
5. In a mixing bowl, whisk together milk, eggs, and parsley; pour the egg mixture over the casserole ingredients and sprinkle with Cheddar cheese. Cover the dish and refrigerate for a minimum of 8 hours or overnight.
6. When ready to bake the casserole, preheat oven to 400 degrees F (200 degrees C). Bake uncovered in the preheated oven until the casserole is set and golden brown, about 1 hour.
7. Cut into squares, serve hot, and enjoy your Christmas brunch casserole!
