This hearty breakfast casserole layers savory sausage, golden bread, fluffy eggs, and tangy cheddar into one irresistible bake. It is a lifesaver for busy mornings when you need to feed a crowd or set up easy leftovers for grab-and-go breakfasts.
I first made this when hosting a holiday brunch for my family. Everyone went back for seconds and now it is my most requested special breakfast.
Ingredients
- Breakfast sausage pork or turkey: adds a rich savory base to every bite Find the freshest local sausage for the best flavor and check for seasoning
- Day-old bread like French bread or sourdough: gives structure and soaks in all the goodness Opt for sturdy loaves that hold up well
- Shredded sharp cheddar cheese: brings a tangy bite and creamy melt Look for a block you can shred yourself to avoid fillers
- Whole milk: creates that custardy egg texture Choose full fat for a richer flavor
- Eggs: bind everything together and create the fluffy, baked texture Use large fresh eggs
- Onion and red bell pepper: add subtle sweetness and color Choose firm vegetables
- Salt black pepper dried mustard and paprika: build layers of savory taste Smoked paprika adds depth if using
- Chopped chives or parsley for garnish: give freshness and color Snip right before serving for best flavor
Instructions
- Prepare the Baking Dish:
- Grease a 9 by 13 inch baking dish with butter or nonstick spray making sure to cover every corner so nothing sticks
- Brown the Sausage:
- Crumble the sausage into a large skillet over medium heat Cook for about seven minutes stirring to break apart until browned throughout and no pink remains Transfer to a plate and drain any extra fat for a lighter casserole
- Sauté the Vegetables:
- In the same skillet add chopped onion and red bell pepper Cook over medium until they are soft and smell sweet about three minutes Remove from heat
- Make the Egg Custard:
- In a large mixing bowl whisk eggs until smooth Add whole milk salt pepper dried mustard and paprika Continue whisking until fully blended and a little frothy
- Layer the Ingredients:
- Scatter the cubed bread evenly in the greased baking dish Sprinkle cooked sausage on top followed by sautéed onion and pepper Spread one and a half cups of the shredded cheddar over everything
- Pour the Egg Mixture:
- Slowly pour the egg custard evenly over all the layers Press down gently with a spatula so the bread absorbs the liquid
- Top with More Cheese:
- Sprinkle the remaining cheddar cheese over the surface for maximum melty goodness
- Bake the Casserole:
- Place uncovered into a preheated 350 degree oven Bake for forty to forty five minutes until golden brown on top and no longer jiggly in the center
- Rest and Garnish:
- Let the casserole cool for about ten minutes before slicing so it sets up Sprinkle with fresh herbs if you like Serve warm with coffee or juice

Sharp cheddar has become my favorite part of this casserole because its tangy bite cuts through the richness My kids love helping me layer the bread and sprinkle cheese and watching it transform in the oven always brings out excited smiles
