Step‑by‑Step Instructions for Overnight Sausage and Egg Breakfast Casserole
Step 1: Cook the Sausage
In a large skillet over medium heat, cook the breakfast sausage for about 5–7 minutes. Use a wooden spoon to crumble the meat as it browns, ensuring it’s no longer pink. Once cooked, transfer the sausage to a paper towel-lined plate to drain any excess grease, keeping it flavorful for your Overnight Breakfast Casserole.
Step 2: Whisk the Eggs
In a large mixing bowl, whisk together 8 jumbo eggs, salt, black pepper, cayenne pepper (if using), ground mustard, dried sage, and dried chives. Slowly add in 1 cup of half-and-half while continuing to whisk until the mixture is smooth and well combined. This egg mixture will form the custard base of your casserole, providing richness to every bite.
Step 3: Layer the Ingredients
Grease a 13″x9″ baking dish with cooking spray or butter. Start layering by evenly distributing the cubed bread across the bottom of the dish. Next, sprinkle in the cooked sausage, followed by a generous portion of yellow and extra sharp white cheddar cheeses. This layering structure allows the flavors of the sausage and cheeses to infuse the bread as it bakes.
Step 4: Combine the Mixtures
Pour the egg mixture evenly over the layered ingredients, ensuring that all the bread pieces are submerged. Use a spatula to gently press down on the bread, allowing it to absorb the custard. Cover the dish tightly with plastic wrap and refrigerate overnight, letting the Overnight Breakfast Casserole soak up all those delicious flavors.
Step 5: Prepare for Baking
The next morning, preheat your oven to 350°F (175°C). Take the casserole out of the refrigerator and allow it to sit at room temperature for 15-20 minutes. This step ensures even cooking, helping prevent a cold center in your Overnight Breakfast Casserole when it bakes.
Step 6: Bake the Casserole
Place the baking dish in the preheated oven and bake for 45-50 minutes. Keep an eye on the casserole—it’s done when the top is golden brown and a knife inserted in the center comes out clean. Allow the casserole to rest for about 5 minutes before cutting into squares, serving up fluffy, cheesy perfection for your holiday breakfast.

Overnight Sausage and Egg Breakfast Casserole Recipe FAQs
How do I choose the best breakfast sausage?
Absolutely! When choosing breakfast sausage, look for fresh, high-quality options that are well-seasoned. If you’re looking for leaner alternatives, turkey or chicken sausage works wonderfully and has a similar flavor profile. Aim for sausages without artificial additives or preservatives for a cleaner taste.
What’s the best way to store leftovers?
You can refrigerate your leftovers in an airtight container for up to 3-4 days. Make sure to let it cool completely before storing, as this will help prevent condensation which can make it soggy. Just reheat individual portions in the microwave or warm it in the oven until heated through — about 20 minutes at 350°F should do the trick!
Can I freeze my casserole before baking it?
Yes, you can! I often make a double batch and freeze one for later. Wrap the unbaked casserole tightly in plastic wrap and aluminum foil to prevent freezer burn. It can stay fresh for up to 3 months. When you’re ready to bake, simply thaw it in the fridge overnight before popping it in the oven — this ensures even cooking!
What if my casserole is too dry after baking?
If you find that your casserole turns out dry, there are a couple of things you can do next time. Make sure the bread is thoroughly soaked in the egg custard overnight. If you notice it becoming dry during baking, cover it with foil to retain moisture. Also, adding more cheese or using a richer milk like half-and-half can help enrich the dish!
Are there any dietary considerations for this casserole?
Very! For those with dietary restrictions, you can easily modify this casserole. Use egg whites or a plant-based egg alternative for everyone watching cholesterol. Gluten-free bread works well if you need a gluten-free option. Additionally, for a vegetarian version, simply omit the sausage and load it up with veggies like spinach or bell peppers for extra nutrition!
How can I make sure the casserole cooks evenly?
To ensure even cooking, allow the casserole to sit at room temperature for 15-20 minutes before baking. This helps bring it to a uniform temperature, preventing a cold center. Also, if you’re using denser bread, keep an eye on the soaking time—thicker slices might need a little more time to absorb the custard for optimal flavor and texture.
