Introduction

Looking for a breakfast that’s hearty, fuss-free, and sure to win over a crowd? This Easy Sausage and Egg Casserole is your answer. Combining savory sausage, fluffy eggs, melty cheese, and bread in one dish, it’s the ultimate make-ahead breakfast or brunch centerpiece—ideal for holidays, meal prep, or feeding hungry guests without the morning rush.

Why This Easy Sausage and Egg Casserole Works

This casserole’s brilliance lies in its balance of rich sausage, creamy eggs, and crispy bread. As it bakes, the flavors meld into each bite, while the golden, cheesy top adds a hint of decadence. Plus, you can prep it the night before, making your morning routine a breeze.

Smart Prep Tips for the Best Casserole

Using prepped ingredients is key to speeding up the process. Quickly dice onions, peppers, or mushrooms (if using) with the Mueller Pro-Series 10-in-1, 8 Blade Vegetable Chopper to save time and ensure even cooking. If shredding your own cheese, a countertop blender like the Ninja BL610 Professional 72 Oz Countertop Blender makes prep extra efficient.

A reliable nonstick skillet, such as the SENSARTE Nonstick Frying Pan Skillet, 9.5 Inch, helps brown your sausage perfectly and makes cleanup simple. Layering the toasted bread adds texture, preventing a soggy bottom.

Assembling and Baking Your Casserole

Grease your baking dish and layer bread, sausage, and cheese before pouring the savory egg mixture over the top. For even baking and easy release, line your dish with a sheet of Reynolds Kitchens Brown Parchment Paper Roll. This helps lift out slices cleanly and keeps your pan pristine.

Letting the casserole rest (or refrigerating overnight) allows the flavors to deepen. When ready to bake, simply slide the dish into the oven and enjoy the mouthwatering aroma as it cooks to golden perfection.

Serving, Storing, and Enjoying

After baking, let the casserole rest a few minutes before slicing. Serve it hot with a side of fresh fruit or a tossed green salad. Leftovers keep well—store tightly sealed portions in Rubbermaid Brilliance Food Storage Containers for a satisfying breakfast on the go.

This casserole is easily customizable. Add sautéed vegetables, swap in turkey sausage, or use a different cheese for a dish that suits your taste.

Instructions

1. Preheat your oven to 350°F. Lightly grease a 9×13-inch baking dish or line it with Reynolds Kitchens Brown Parchment Paper Roll for easy removal.
2. In a skillet, cook the sausage over medium heat, breaking it up with a Farberware Professional Heat Resistant Nylon Meat and Potato Masher until browned and cooked through. Remove from the pan and set aside.
3. If using, sauté onion and bell pepper in the same skillet until softened (about 3 minutes).
4. Layer cubed bread evenly in the prepared baking dish. Sprinkle the cooked sausage, sautéed vegetables, and shredded cheese over the bread.
5. In a large bowl (a pour spout bowl is handy), whisk together eggs, milk, salt, pepper, and dry mustard (if using) until smooth. You can use the Ninja BL610 Professional 72 Oz Countertop Blender for an extra-fluffy egg mixture.
6. Pour the egg mixture evenly over the layered ingredients in the dish. Press down lightly to help the bread soak up the mixture. Cover and refrigerate for at least 30 minutes, or overnight for best results.
7. Uncover and bake for 40–45 minutes, or until puffed, golden brown, and set in the middle. To check doneness, insert a ThermoPro TP19H Digital Meat Thermometer for Cooking; the center should read 160°F.
8. Let the casserole cool for 5–10 minutes, garnish with fresh parsley, then slice and serve.
