Step‑by‑Step Instructions for Loaded Baked Egg Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 180°C (350°F). While it warms up, grab a 9×13-inch baking dish and generously grease it with olive oil or butter to prevent the Loaded Baked Egg Casserole from sticking. This initial step is crucial for achieving that perfect golden top when baking!
Step 2: Prepare the Mix-Ins
In a large skillet over medium heat, cook your bacon or sausage until it’s nicely browned and crispy, which should take about 5–7 minutes. Drain the excess grease and transfer the meat to a plate. Next, chop your bell peppers and onion, and if you’re using fresh spinach, give it a rough chop too. Set these aside; they’ll add color and flavor to your casserole.
Step 3: Whisk the Eggs
In a big mixing bowl, crack in the large eggs and add your choice of milk or heavy cream, along with a generous pinch of salt, pepper, and garlic powder. Whisk everything together until it’s slightly frothy, which should take around 2 minutes. This egg mixture helps bind all the ingredients in the Loaded Baked Egg Casserole, contributing to its fluffy texture.
Step 4: Assemble the Casserole
Now, layer your prepped ingredients in the greased baking dish. Begin with the cooked bacon or sausage, followed by the diced bell peppers, onions, and chopped spinach. Finally, sprinkle shredded cheddar cheese over the top. Pour the egg mixture evenly across all the layered ingredients, ensuring everything is well coated.
Step 5: Bake the Casserole
Place the baking dish in your preheated oven and bake the casserole for 35–40 minutes. You’ll know it’s ready when the edges are lightly golden, and the center is set but still a little jiggles. If the top browns too quickly, feel free to cover it with foil to prevent burning while the inside cooks through.
Step 6: Rest and Serve
Once baked, remove the Loaded Baked Egg Casserole from the oven and let it rest for 5–10 minutes. This resting time makes it easier to slice and serve while allowing the flavors to meld together. Cut into squares and serve warm, and enjoy the comfort of a homemade meal with your loved ones!

Make Ahead Options
These Loaded Baked Egg Casserole preparations are ideal for busy home cooks looking to save time! You can chop the vegetables and cook the bacon or sausage up to 24 hours in advance. Just store the prepped ingredients in separate airtight containers in the refrigerator. Additionally, you can whisk the egg mixture the night before and refrigerate it overnight to keep it fresh. When you’re ready to bake, simply assemble the casserole with the prepped components, pour the egg mixture over, and bake as directed. This approach maintains quality, ensuring your Loaded Baked Egg Casserole is just as delicious when ready to serve, offering you a comforting meal with minimal effort during hectic mornings!
