Ingredients for Holiday Brunch Casserole
Here’s what you’ll need to make this delicious Holiday Brunch Casserole:
8 large eggs – Fresh eggs are key for a fluffy casserole; consider pasture-raised for extra flavor.
1 cup whole milk – This adds creaminess and richness, making your casserole irresistibly smooth.
1 cup shredded sharp cheddar cheese – Sharp cheddar gives a bold flavor that perfectly complements the dish.
2 cups cooked bacon or sausage, chopped – Use your favorite breakfast meats here for that hearty, savory goodness.
2 cups fresh baby spinach – Spinach adds color and nutrients, and wilts down to enhance the flavor without overpowering it.
1 medium onion, diced – A pop of sweetness when sautéed; it enhances the overall taste profile of the casserole.

Nonstick cooking spray – A must for preventing any sticking mishaps, ensuring that perfect slice at serving time.
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). This is important because starting with a hot oven ensures even cooking for your casserole. While the oven warms up, grab a delicious 9×13-inch baking dish and spray it lightly with nonstick cooking spray to prevent any sticking.
Step 2: Cook the meat
In a skillet over medium heat, cook your bacon or sausage until it’s nice and crispy. When done, drain it on paper towels to absorb the excess grease, and chop it into bite-sized pieces. This step adds rich flavor and texture to your casserole.
Step 3: Sauté the veggies
Using the same skillet, toss in your diced onion and cook until it turns translucent—about 3–5 minutes. Then, add in the fresh baby spinach and stir until it wilts, which should take about 2 minutes. This adds not just flavor but also beautiful green specks to your dish.
Step 4: Whisk the egg mixture
In a large bowl, whisk together the 8 large eggs and 1 cup of whole milk until well combined. Season this mixture generously with salt and pepper. This creates a creamy base that’s crucial for that omelet-like texture.
Step 5: Combine and pour into the dish
Now it’s time to combine everything! Stir in the cooked bacon or sausage, sautéed onion, spinach, and half of your shredded cheddar cheese into the egg mixture. Once it’s well blended, pour this delicious concoction into your prepared baking dish.
Step 6: Bake and serve
Sprinkle the rest of the cheese on top and slide the baking dish into the oven. Bake for 30-35 minutes, until the center is set and the top is beautifully golden brown. This is the moment you’ve been waiting for; slice and serve it warm, pairing it with fresh fruit or a light salad for a complete brunch experience.
Remember to prepare for the tasty compliments coming your way each time someone takes a bite of this Holiday Brunch Casserole! Enjoy the laughter and love shared around the table, savoring every mouthful of this delightful concoction.
