How to Make Easy Make-Ahead Breakfast Casserole
Start by cooking your meat until crispy. In a skillet over medium heat, add chopped bacon or sausage and cook until golden brown, creating that delightful sizzle sound that says breakfast is coming.
Next, sauté the onions and bell peppers. In the same skillet, toss in diced onion and bell pepper; cook until they’re soft and aromatic—about five minutes should do it.
Whisk together the eggs and milk. Grab a bowl and whisk together six large eggs with one cup of milk until it looks beautifully frothy—this adds volume to your casserole!
Combine everything in a baking dish. In a greased 9×13 inch baking dish, layer the cooked meat, sautéed veggies, and shredded cheese before pouring the egg mixture on top.
Bake to perfection. Preheat your oven to 350°F (175°C) before popping the casserole in for about 30-35 minutes or until golden brown on top.
Let it rest before serving. Once baked, allow it to cool slightly so it sets well—this will help you cut those perfect squares later.
Enjoy! Serve warm with a sprinkle of fresh herbs on top for an extra touch—get ready for compliments from family and friends.
Now you’ve mastered the art of crafting an Easy Make-Ahead Breakfast Casserole that will leave everyone craving more!
