Step-by-Step: Easy Sausage Breakfast Casserole

Step 1: Prepare the Bread

Trim the crusts off your bread slices and cut them into roughly one-inch cubes. Using slightly stale bread helps it soak up the custard perfectly without becoming mushy.

Step 2: Cook the Sausage

In a skillet over medium heat, cook your sausage until fully browned and crumbled. Drain any excess fat to keep the casserole from being greasy, then set aside.

Step 3: Mix the Custard

In a large mixing bowl, whisk together the eggs, milk, half and half cream, Dijon mustard, Worcestershire sauce, salt, pepper, and nutmeg until everything is well combined and smooth.

Step 4: Assemble the Casserole

Grease your casserole dish lightly. Spread half the bread cubes evenly across the bottom. Sprinkle half the cooked sausage and half the shredded cheddar cheese over the bread. Repeat with the remaining bread, sausage, and cheese layers.

Step 5: Pour the Custard

Slowly pour the egg mixture over the layered ingredients, pressing gently to help the bread absorb the custard. Let it sit for about 10 minutes to soak in fully.

Step 6: Bake

Preheat your oven to 350°F (175°C). Place the casserole dish in the oven and bake for 40-45 minutes, or until the top is golden brown and the custard is set in the center. A knife inserted should come out clean.

Step 7: Serve

Let the casserole cool slightly before cutting into squares. Serve warm, alongside fresh fruit or a light salad for a complete breakfast or brunch experience.

Quick Replacement Ideas

• Swap sausage with ground chicken or turkey for a leaner option.
• Use mozzarella or Monterey Jack cheese instead of cheddar for a milder flavor.
• Replace half and half cream with full-fat coconut milk for a dairy-free twist.
• Try different bread types like whole wheat, sourdough, or even croissants for a richer texture.

Troubles You Can Avoid

• Too soggy or too dry: Make sure to let the bread soak in the custard for at least 10 minutes but not longer than 20 to avoid a mushy texture.
• Under-cooked center: Ensure your oven temperature is accurate and bake until the custard is fully set.
• Greasy casserole: Drain the cooked sausage well to prevent excess fat pooling in the dish.
• Bland flavor: Don’t skip the mustard and Worcestershire sauce; these add essential depth to the dish.

Make Ahead Like a Pro

This Easy Sausage Breakfast Casserole is a fantastic make-ahead option. Assemble the casserole the night before, cover it tightly with plastic wrap or foil, and refrigerate overnight. In the morning, simply bake as directed, adding a few extra minutes to the cooking time since it’s cold from the fridge. This prep method not only saves time but also allows the flavors to meld beautifully, resulting in an even tastier dish.

Common Questions

Can I prepare this casserole without bread?

While bread helps create the classic texture and structure of this casserole, you can substitute with cooked rice or potatoes for a grain-free alternative. Just note the texture and soaking properties will differ.

Is it possible to freeze the casserole?

Yes! Prepare the casserole up to the assembly stage, cover tightly with foil, and freeze. When ready to eat, thaw overnight in the fridge and bake as usual, adding extra baking time if still partially frozen.

Can I make this casserole vegetarian?

Absolutely. Replace the sausage with sautéed mushrooms, diced bell peppers, or a plant-based sausage substitute to keep it hearty and flavorful.

What sides pair well with this breakfast casserole?

Fresh fruit salad, roasted vegetables, or a simple green salad complement the rich casserole nicely. For a twist, try it alongside our Cajun Sausage And Pasta Skillet for a complete brunch spread.
