History and Origins

Sausage Breakfast Casserole: A Hearty and Satisfying Morning Delight

Breakfast casseroles have been a part of American cuisine for decades, reflecting the nation’s love for hearty, one-dish meals that can feed a crowd. The sausage breakfast casserole, in particular, likely evolved from the tradition of breakfast bakes and stratas, which combine bread, eggs, cheese, and various meats or vegetables. These dishes were designed for convenience and versatility, allowing cooks to use up leftovers and prepare a filling meal with minimal effort. Over time, the sausage breakfast casserole has become a classic, enjoyed in households across the country and often featured in holiday and special occasion menus.


The ingredients for a sausage breakfast casserole are simple and flexible, allowing for numerous variations. Here are the basic components you will need:

  1. Sausage: Bulk breakfast sausage or sausage links that have been removed from their casings.
  2. Eggs: The base of the casserole, providing structure and richness.
  3. Milk: Adds creaminess and helps the eggs to set.
  4. Cheese: Shredded cheddar or a combination of cheeses for flavor and gooey texture.
  5. Bread: Cubed bread serves as the base and absorbs the egg mixture. Day-old or slightly stale bread works best.
  6. Seasonings: Salt, pepper, and optional seasonings such as garlic powder, onion powder, and herbs.
  7. Vegetables (optional): Diced onions, bell peppers, spinach, or mushrooms can be added for extra flavor and nutrition.


Preparing a sausage breakfast casserole is straightforward and can be done in advance. Here’s a step-by-step guide:

  1. Cook the Sausage: In a large skillet over medium heat, cook 1 pound of breakfast sausage until browned and cooked through, breaking it into crumbles as it cooks. Drain any excess fat and set aside.
  2. Prepare the Bread: While the sausage is cooking, cut 6-8 slices of bread into 1-inch cubes. Arrange the bread cubes in a single layer in a greased 9×13-inch baking dish.
  3. Add the Sausage: Sprinkle the cooked sausage evenly over the bread cubes.
  4. Prepare the Egg Mixture: In a large bowl, whisk together 8 large eggs, 2 cups of milk, 1 teaspoon of salt, 1/2 teaspoon of pepper, and any additional seasonings you prefer (such as 1/2 teaspoon each of garlic powder and onion powder).
  5. Add Cheese and Vegetables: Stir in 2 cups of shredded cheddar cheese and any optional vegetables into the egg mixture. Pour this mixture evenly over the bread and sausage in the baking dish, pressing down gently to ensure the bread absorbs the liquid.
  6. Chill (optional): For best results, cover the casserole with plastic wrap and refrigerate for at least 1 hour or overnight. This allows the bread to fully absorb the egg mixture. However, if you are short on time, you can bake it immediately.
  7. Bake: Preheat the oven to 350°F (175°C). Remove the plastic wrap and bake the casserole for 45-50 minutes, or until the top is golden brown and a knife inserted into the center comes out clean. Let the casserole rest for 5-10 minutes before serving.
