Before you start cooking, gather these simple ingredients that come together for a hearty make-ahead brunch.

How To Make Overnight Crockpot Christmas Breakfast Casserole
Get ready to let your Crockpot do all the heavy lifting! From greasing the insert to layering the custardy egg mixture over bread cubes, these steps will guide you through assembling the casserole before bedtime so you can wake up to a fully cooked holiday breakfast.
1. Grease the Crockpot
Spray the inside of your Crockpot with cooking spray or drizzle with olive oil to prevent sticking and make serving a breeze.
2. Cook the sausage
In a skillet over medium heat, brown the crumbled breakfast sausage until no pink remains. Drain any excess fat and set the sausage aside to cool slightly.
3. Whisk the eggs
Crack the 6 large eggs into a large mixing bowl and whisk until the yolks and whites are fully combined and slightly frothy.
4. Add the milk
Pour in 2 cups of milk and continue whisking until the mixture is smooth, pale, and uniform in consistency.
5. Stir in the mix-ins
Add shredded cheddar, diced hash browns, bell pepper, onion, garlic powder, salt, black pepper, paprika, and optional cayenne. Stir until every ingredient is evenly distributed.
6. Fold in the sausage
Gently fold the cooked breakfast sausage into the egg mixture, making sure it’s spread throughout.
7. Layer the bread cubes
Place the cubed bread in an even layer at the bottom of the greased Crockpot, then pour the egg-sausage mixture on top, pressing lightly so every cube soaks up the custard.
8. Cook on low
Cover with the lid and set your Crockpot to Low. Let it cook for 8 hours, or until the eggs are fully set and the top is firm.
9. Let it rest
Turn off the Crockpot and let the casserole sit, covered, for 10 minutes. This resting step allows steam to escape and helps the casserole firm up for neat slices.
10. Serve warm
Scoop out portions and top with extra cheese, chopped herbs, or your favorite breakfast toppings for an extra festive touch.

Serving this casserole is half the fun—pick a cozy spot around the table or let guests help themselves buffet-style. A variety of toppings and side dishes can turn it into a full holiday spread.

Frequently Asked Questions
Curious about timing, tweaks, or reheating? Here are answers to some common queries to help you get the best results from your Overnight Crockpot Christmas Breakfast Casserole.
- How long does it take to prepare and cook the Overnight Crockpot Christmas Breakfast Casserole?
Preparation takes about 20–30 minutes, which includes browning the sausage, chopping vegetables, whisking eggs with milk, and assembling the casserole in the Crockpot. Cooking on the low setting requires 8 hours, and after cooking you should let it rest for 10 minutes before serving. In total, plan for roughly 8½ to 9 hours from start to finish.
- Can I assemble the casserole the night before and refrigerate?
Yes. You can layer the bread cubes, pour in the egg and sausage mixture, cover the Crockpot insert, and refrigerate overnight. In the morning, simply place the insert into the Crockpot base and set to low for 8 hours. Allowing the mixture to soak overnight helps the bread absorb more of the egg mixture for a moister texture.
- What should I do if my casserole turns out too wet or soggy?
If the casserole is too wet, first ensure you’re draining any excess liquid from thawed hash browns before adding them. You can also reduce the milk to 1½ cups. After cooking, let it rest with the lid slightly ajar for an additional 10–15 minutes to allow steam to escape and the casserole to firm up.
- Can I substitute or add other ingredients?
Absolutely. You can swap breakfast sausage for cooked bacon, diced ham, or a plant-based sausage. Feel free to mix in vegetables like spinach, mushrooms, or tomatoes, and experiment with cheeses such as pepper jack, Swiss, or feta. Just be mindful of moisture content when adding vegetables—sauté mushrooms or drain excess liquid from fresh spinach.
- What if I don’t have 8 hours to cook on Low—can I use a High setting?
Yes, you can cook on High for approximately 4–5 hours, though texture may vary slightly. The eggs may set faster but the flavors have less time to meld and the bread might not absorb as fully. If you choose this option, check doneness with a knife or toothpick inserted in the center; it should come out clean when the casserole is fully cooked.
- How should I store and reheat leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place individual portions on a microwave-safe plate and heat on medium power for 1–2 minutes, or until warmed through. You can also reheat slices in a toaster oven at 350°F for 8–10 minutes for a crisper top.
- Can I freeze this casserole?
You can freeze cooked and cooled portions for up to 2 months. Wrap each portion tightly in plastic wrap and aluminum foil before placing in a freezer bag. Thaw overnight in the refrigerator, then reheat in the microwave or oven until heated through. Freezing the uncooked assembled casserole is not recommended, as texture and rise may be affected.
