History
While modern breakfast casseroles delight our senses with their visual appeal, the origins of this beloved dish stretch back to mid-20th century America, when home cooks began experimenting with make-ahead breakfast solutions.
You’ll find that casseroles gained popularity during the post-war era, as convenient, all-in-one dishes became essential for busy families juggling work and home life. The addition of eggs and breakfast meats transformed the traditional casserole into a morning staple, while the rise of low-carb dieting in the 1970s paved the way for today’s keto variations.
You might be surprised to learn that your grandmother’s cheese and egg bake wasn’t far from today’s keto versions – they’ve simply evolved to meet modern nutritional preferences while maintaining that comforting, home-cooked essence.
Recipe

A keto breakfast casserole combines the heartiness of a traditional breakfast with the low-carb requirements of a ketogenic diet. This versatile dish can be prepared ahead of time and reheated throughout the week, making it perfect for busy mornings when a nutritious breakfast is essential.
This protein-rich casserole features eggs as its base, complemented by various meats, cheeses, and low-carb vegetables. The combination creates a filling meal that helps maintain ketosis while providing sustained energy throughout the morning.
- 12 large eggs
- 1 pound breakfast sausage
- 8 slices bacon, chopped
- 2 cups heavy cream
- 2 cups shredded cheddar cheese
- 1 cup diced bell peppers
- 1/2 cup diced onions
- 2 cloves minced garlic
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon dried oregano
- 1/4 teaspoon red pepper flakes
Preheat oven to 375°F and grease a 9×13 inch baking dish. Brown the sausage in a large skillet, then set aside. Cook bacon until crispy in the same skillet, then remove. Sauté onions, peppers, and garlic in the remaining fat until softened.
In a large bowl, whisk eggs, cream, salt, pepper, and oregano. Layer the meat and vegetables in the baking dish, top with cheese, then pour the egg mixture over everything. Bake for 35-40 minutes until set and golden brown.
For a dairy-free version, substitute coconut cream for heavy cream and dairy-free cheese alternatives. The vegetables can be swapped based on preference – spinach, mushrooms, or asparagus work well.
When reheating portions, add a splash of water and cover with foil to prevent drying. The casserole can be frozen for up to three months when wrapped properly in freezer-safe containers.
