Ingredients
Gather these simple ingredients to create your irresistible Loaded Baked Egg Casserole. Each component contributes to the casserole’s rich flavor and satisfying texture.
- 1 pound bacon, cooked and chopped
- 12 ounces breakfast sausage, uncooked
- 28 ounces frozen potatoes with peppers and onions, thawed
- 2 cups shredded cheddar cheese
- 12 large eggs
- 1/2 cup whole milk
- 1 1/2 teaspoons kosher salt
- 1 teaspoon fresh ground black pepper
- 1 teaspoon garlic powder
Notes & Substitutions
Ensure your bacon is fully cooked and chopped before adding it for the best texture and flavor. Use bulk breakfast sausage (from a roll) for easy browning and crumbling. Always thaw your frozen potatoes completely to prevent a watery casserole. Medium-sharp cheddar offers a great balance of flavor, but mild works too. Whole milk helps create extra tender, fluffy eggs. For substitutions, you can use any milk alternative, different shredded cheeses like Colby Jack or Monterey Jack, or even pre-cooked ham instead of bacon or sausage.
Equipment
You only need a few basic kitchen tools to make this delightful baked egg casserole:

Instructions
Creating this Loaded Baked Egg Casserole is straightforward. Follow these steps for a perfectly cooked, golden-brown breakfast bake.
Step 1: Prep Oven & Dish
Preheat your oven to 375°F (190°C). Lightly grease a 9 by 13-inch baking dish with nonstick cooking spray. This prevents the casserole from sticking and makes cleanup easier.
Step 2: Cook Sausage
Place a large skillet over medium heat. Add the 12 ounces of uncooked breakfast sausage. Cook, breaking it up with a spatula, until it is browned and fully cooked through. No pink should remain. Remove the skillet from heat and drain any excess grease thoroughly.
Step 3: Combine Fillings
Add the cooked sausage, 1 pound of cooked and chopped bacon, 28 ounces of thawed frozen potatoes with peppers and onions, and 2 cups of shredded cheddar cheese to the prepared baking dish. Gently toss these ingredients together to ensure they are evenly distributed across the bottom of the dish.
Step 4: Prepare Egg Mixture
In a large mixing bowl, combine the 12 large eggs, 1/2 cup whole milk, 1 1/2 teaspoons kosher salt, 1 teaspoon fresh ground black pepper, and 1 teaspoon garlic powder. Whisk everything together thoroughly until the mixture is fully combined and smooth.
Step 5: Assemble Casserole
Pour the prepared egg mixture evenly over the potato, meat, and cheese mixture in the baking dish. Use a spoon to gently press down on the solid ingredients. This helps the eggs settle around and throughout the filling for an even cook.
Step 6: Bake
Place the uncovered baking dish into the preheated oven. Bake for 35 to 40 minutes. The Loaded Baked Egg Casserole is ready when the center is set and a knife inserted into the middle comes out clean. The top should be lightly golden brown.
Step 7: Rest and Serve
Once baked, remove the casserole from the oven. Let it rest for 5 to 10 minutes before slicing and serving. Resting allows the eggs to set further, creating cleaner, firmer slices that hold their shape beautifully.
Pro Tips & Troubleshooting
Achieve the perfect baked egg casserole every time with these helpful tips:
- Thaw potatoes completely: This crucial step prevents excess moisture, ensuring your casserole is not watery.
- Pre-cook all meats: Fully cook bacon and sausage to render fat and enhance flavor. This also prevents a soggy casserole.
- Don’t overmix eggs: Whisk just enough to combine ingredients. Overmixing can lead to tougher eggs.
- Press fillings gently: After pouring the eggs, gently press the solids down. This ensures everything is submerged for even cooking.
- Check for doneness: If the center is still wobbly, it needs more baking time. The internal temperature should be 160°F. To ensure food safety, the USDA recommends that all egg dishes, including casseroles, reach a safe minimum internal temperature for egg dishes.
- Allow resting time: Resting sets the eggs, making for neat, firm slices without crumbling.
- Adjust seasonings: Taste your egg mixture before adding to the casserole. Adjust salt and pepper as needed.
- Prevent sticking: Grease your baking dish generously with cooking spray or butter for easy removal.
Serving Suggestions, Storage & Variations
This versatile breakfast bake offers many possibilities for enjoyment.
Serving Ideas
Serve your hearty baked egg casserole alongside fresh fruit salad, crispy toast, or flaky biscuits. Top individual servings with a dash of hot sauce, a dollop of sour cream, or fresh green onions for extra flavor. Pair with a hot cup of coffee, a celebratory mimosa, or a spicy Bloody Mary for brunch.
Storage & Reheating
Store leftover Loaded Baked Egg Casserole in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 1-2 minutes until warm. You can also reheat the entire casserole in a 300°F oven for about 15-20 minutes, covered, until heated through.
Make Ahead & Freezing
Assemble the entire casserole the night before, cover it tightly, and refrigerate. Bake it fresh in the morning, adding about 5-10 minutes to the baking time. For freezing, cook the casserole completely, let it cool, then slice into individual portions. Wrap each piece tightly in plastic wrap, then foil, and freeze for up to 2 months. Thaw overnight in the refrigerator and reheat as desired.
Flavor Variations
Experiment with different ingredients to customize your egg bake. Try adding sautéed mushrooms, fresh spinach, or diced bell peppers for extra vegetables. Swap cheddar for Colby Jack, Pepper Jack, or a Mexican cheese blend. For a spicy kick, use hot breakfast sausage or add diced jalapeños. You can also include other proteins like diced ham, cooked ground turkey, or even smoked salmon.
