Step-by-step method
Step 1
First things first, preheat your oven to 350 degrees F. Sometimes I forget and have to wait impatiently, but trust me, it’s worth it. Lightly grease a 9×13 inch baking dish with a little cooking spray, so nothing sticks and cleanup is easy. Then, scatter the cubed white bread evenly across the bottom. It doesn’t have to be perfect—some uneven edges just make it homier.
Step 2
Next, sprinkle the cooked sausage on top. If you want to swap for turkey sausage or a veggie version, that’s totally fine. After that, toss on the diced red pepper and sweet onion. The colors always look so festive, don’t they? Then, sprinkle the cheddar cheese right over everything. Sometimes I use a little extra cheese, but that’s just me.
Step 3
Now, in a bowl, whisk together eggs, milk, Worcestershire, dijon, salt, and pepper. Pour this mixture evenly over the casserole layers, making sure it soaks in everywhere. Pop the dish in the oven for 50-55 minutes until it’s set and golden on top. While you wait, maybe check out some other cozy ideas like Blueberry French Toast Casserole Breakfast Recipes for next time.
Tips and tricks to make this recipe shine
Let the casserole rest for 10 minutes before slicing so it sets up nicely. If you like a crispier top, broil it for a minute at the end, but watch closely. You can prep everything the night before and bake in the morning for less stress—perfect for busy holiday mornings. Oh, and don’t worry if it puffs up a little unevenly in the oven; that’s just part of its charm.
What to serve with this recipe
Honestly, this christmas breakfast casserole feels like a meal all on its own, but you can always pair it with a fresh fruit salad for some brightness. Maybe serve with a side of roasted potatoes or even some flaky biscuits. If you love breakfast casseroles, you might want to try something like Biscuit Gravy Casserole Breakfast Recipes next time for a little southern flair.
How to store and reheat
Leftovers are a gift—just cover the dish tightly and refrigerate for up to 3 days. To reheat, pop single servings in the microwave for about a minute, or warm larger portions in the oven at 325 degrees F until heated through. If you notice it’s a bit dry, a splash of milk before reheating helps bring back that just-baked texture. Sometimes I eat it cold, honestly, and it’s still delicious.
