Ingredients for Holiday Brunch Casserole
Here’s what you’ll need to make this delicious Holiday Brunch Casserole:
8 large eggs – The foundation of your casserole, giving it that fluffy texture. Fresh eggs work best for optimal flavor.
1 cup whole milk – Adds creaminess to the dish, making each bite indulgently rich. You could also use a dairy-free alternative if preferred.
1 cup shredded sharp cheddar cheese – This cheese brings a tangy flavor and gooey texture that stretches tantalizingly with every slice.
2 cups cooked bacon or sausage, chopped – Choose your favorite protein for a savory punch. Crispy bacon adds crunch, while sausage lends a heartier bite.
2 cups fresh baby spinach – Not only does it add vibrant color, but it also balances out the richness of the dish with its fresh, slightly earthy taste.
1 medium onion, diced – Brings sweetness and depth of flavor. Cooked until translucent, it mellows out beautifully.
Salt and pepper to taste – Essential seasonings that enhance every layer of flavor in your casserole.
Nonstick cooking spray – Keeps everything from sticking and ensures a beautiful golden-brown finish.
How to Make Holiday Brunch Casserole
Follow these simple steps to prepare this delicious Holiday Brunch Casserole:
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and generously spray a 9×13-inch baking dish with nonstick cooking spray. This step is crucial to ensure your casserole comes out perfectly without any mishaps.
Step 2: Cook the Meat
In a skillet over medium heat, cook the bacon or sausage until crispy. Once done, drain the excess fat on paper towels, and chop the meat into bite-sized pieces. Trust me, this is the best part to sneak a piece mid-cooking.
Step 3: Sauté the Vegetables
In the same skillet that held your meat, toss in the diced onion. Sauté until translucent, and then add the baby spinach, cooking until it wilts. This aromatic duo sets the stage for your casserole, providing a savory base.
Step 4: Whisk the Eggs and Milk
In a large mixing bowl, whisk together the eggs and milk until fully combined. Season generously with salt and pepper to taste. This mixture is the star of the show; it cradles all those delicious ingredients together.
Step 5: Combine All Ingredients
Stir in the chopped bacon or sausage, the sautéed onion and spinach, and half of the shredded cheddar cheese into the egg mixture. Pour this delightful concoction into the prepared baking dish, spreading everything evenly.
Step 6: Bake and Serve
Sprinkle the remaining cheese on top, and bake in your preheated oven for 30 to 35 minutes, or until the casserole is set in the center and a glorious golden-brown crust forms on top. Let it cool for a few minutes before slicing and serving. Pair it with some fresh fruit or a light salad for the ultimate brunch experience.
This Holiday Brunch Casserole is more than just a meal; it’s a celebration of flavors and camaraderie. Picture your friends and family gathered around a table filled with laughter and joy. Enjoy every delicious bite of this casserole, and don’t forget to take a moment to appreciate the special times spent with loved ones during the holidays.
