Why You’ll Love This Recipe
Make-Ahead Magic
The beauty of this casserole lies in its convenience. You can assemble the entire dish, cover it, and let it sit in the refrigerator overnight. This allows the bread to soak up the egg mixture completely, resulting in a soufflé-like texture that is fluffy and delicious.
Versatile & Customizable
Think of this recipe as a blank canvas. While sausage and cheddar are classic, you can easily swap in bacon, ham, or a variety of vegetables like peppers, onions, and spinach to suit your taste preferences or use up leftovers.

- 0.5 tsp Salt

Ingredient Highlights & Substitutions
Essential Ingredients
The base requires stale bread (cubed), eggs, milk, ground breakfast sausage, and plenty of shredded cheddar cheese. Dry mustard powder is a key seasoning that enhances the cheesy flavor without being overpowering.
Smart Substitutions
Sourdough or French bread works best for the structure, but even regular sandwich bread can be used in a pinch. For a lighter version, use turkey sausage and skim milk, though whole milk or half-and-half yields the richest custard.
Step-by-Step Instructions
Prep Phase
Brown your sausage in a skillet and drain the fat. Cube your bread into 1-inch pieces. Grease a 9×13 baking dish. Whisk the eggs, milk, and seasonings together in a large bowl.
Cooking Phase
Spread the bread cubes in the baking dish. Top evenly with the cooked sausage and shredded cheese. Pour the egg mixture over everything, ensuring all the bread is soaked. If making ahead, refrigerate now. When ready, bake at 350°F (175°C) for 40-50 minutes until the center is set and the top is golden brown.
Pro Tips for Perfect Results
Technique Secrets
Letting the casserole sit for at least 15 minutes before baking (even if not doing it overnight) is crucial. This resting time ensures the bread absorbs the custard rather than just floating in it, preventing a watery bottom layer.
Common Mistakes to Avoid
Don’t cover the casserole with foil for the entire baking time, or the top won’t get crispy. If you find the top is browning too fast, tent it with foil only for the last 10 minutes. Also, let it rest for 10 minutes after taking it out of the oven to set before cutting.
Serving Ideas & Pairings
Presentation & Plating
Cut the casserole into squares and serve warm. A garnish of chopped chives or green onions adds a fresh bite. Hot sauce or salsa on the side is a popular addition for those who like a kick.
Pairing Suggestions
Serve this hearty main with a fresh fruit salad or yogurt to balance the richness. If you love savory, one-pan sausage dishes, you might also enjoy these Cheesy Ranch Potatoes with Smoked Sausage for a similarly satisfying meal.
