Crockpot recipes are great on busy mornings, but they're even better for Christmas morning breakfast.

📖 Make it your own: yummy variations
Slow cooker breakfast recipes are easy to adapt, so you can make something your entire family will love! Here are some ideas:
- I prefer to use regular sausage, but for a hearty breakfast that's just a touch lighter on the calories, swap in some turkey sausage.
- Some people like to use frozen tater tots instead of shredded potatoes.
- No Pepper Jack? Monterey Jack is good in this breakfast Christmas casserole, too.
- Add a can of diced green chiles to the green peppers mixture for spice!
- Garnish with green onions or parsley for a delicious herbal flavor.
- Don't forget your favorite toppings. Serve with hot sauce, pico de Gallo, a scoop of sour cream, ketchup, or even some maple syrup for a sweet touch.

Whisk the eggs, milk, salt, and pepper together in a large bowl.
Place ⅓ of the potatoes on the bottom of the crockpot.
Spoon ⅓ of the sausage, red and green bell peppers, and diced yellow onions on top of the potatoes.
Top with cheese, repeat layers twice, and pour egg mixture over top.
🤫 Marye's secret for zhuzhing it up -
I will often switch Pepper Jack for the Monterey Jack cheese and stir in a handful of chopped cilantro to give it more of a Tex-Mex flavor.
zhuzh: verb. To make something more interesting or attractive

🥫 Leftover love: how to store and reheat a Crockpot breakfast casserole
This crockpot breakfast casserole recipe usually doesn't often yield any leftovers. The delicious smells wafting out of the kitchen by 7 AM means everyone is ready to scarf down breakfast!
However, if you do have leftovers, spoon them into an airtight container. Like most egg bake recipes, the leftovers will last for about three days in the refrigerator.
Microwave individual servings until just warm for an easy breakfast, days after the festivities have ended.
This freezes well. Let the casserole cool then cut into serving sized squares. Freeze in individual freezer bags for a quick and easy breakfast.
Marye's Tip o' the day
Spray the crockpot well with nonstick cooking spray, because the cheese and potatoes tend to get all crispy around the edges. It's yummy but can stick if not greased well.
💭 Insider tips: things to know
- Use a
slow cooker liner if you prefer no clean-up at all. Just be careful not to cut the liner and accidentally serve it stuck to the bottom of your breakfast casserole! - Drain off the excess fat if you're browning the sausage yourself. Breakfast meat tends to have a lot of extra grease, and you don't need that in the casserole.
- Beating the eggs with a whisk is the key to fluffy eggs. Try to incorporate in as much air as possible.
- Want breakfast now? Prepare as directed, layering the ingredients into a large, oven-proof skillet. Bake at 375 degrees F for about 30 minutes, or until the eggs are cooked all the way through.
- No
slow cooker ? Here are some options for when your slow cooker is out of commission.
👩🍳 Let's answer those questions: FAQs
Have other questions? Ask me in the comments!
You can! Thankfully, there's a little bit of lee-way when it comes to eggs out of their shells. After prep, cover the crockpot dish with plastic wrap or the lid and put it in the fridge until later that night.
I don't love how this Crockpot Christmas casserole comes out when the crockpot cook time and temperature have been altered. However, see the Things to Know section to cook this recipe in a cast iron skillet, instead.
⏲️ Marye's time saving hacks -
Grab diced onions and diced bell peppers in the produce section of your grocery store. You'll save 10 minutes of chopping time.

🍽️ No waste: creative ways to repurpose
Here are five delicious ways to repurpose leftover crockpot breakfast casserole:
- Breakfast Burritos – Scoop portions of the casserole into tortillas, add some salsa, avocado, or extra cheese, and roll them up for quick breakfast burritos. Perfect for freezing and reheating, too!
- Hash Brown Bowl – Reheat a serving, then top with fresh ingredients like diced tomatoes, green onions, hot sauce, and a dollop of sour cream for a hearty breakfast bowl with extra flavor.
- Egg Muffins – Press spoonfuls of the casserole into a greased muffin tin, add a sprinkle of cheese on top, and bake until heated through. They’re easy to grab and go!
- Breakfast Quesadilla – Spread some casserole filling on a tortilla, add shredded cheese, then fold it in half and cook in a skillet until the tortilla is crispy and the cheese is melted. Great with a side of salsa!
- Loaded Breakfast Sandwich – Layer a slice of the casserole on a toasted English muffin or bagel, add some fresh spinach, and top with a slice of tomato or avocado for a filling breakfast sandwich.
These creative twists will help you enjoy every last bite!
📞 Wrapping it up: the last word

Katie Rowland says
The casserole made a hearty, savory breakfast. The left-overs reheat well in the microwave. My only suggestion would be to decrease the hash brown potatoes to 1 pound instead of 2.
Ashley says
This wasn’t very good. Texture was weird, cheese got chewy, it all got watery in the bottom of the crockpot. Lacked flavor. My kids like egg bakes but wouldn’t eat this. Now have to choke down what we can of the leftovers, most will prob get thrown out. Going back to tried & true recipes in the future.
Shelley says
Made this for Christmas breakfast today- was great! Modified for my family, used two packages of sausage, used tator tots, omitted peppers, subbed onion powder for onions, used two 2 cup pkgs of shredded cheese and added an extra cup of milk as my vintage weather rectangular crockpot runs hot— even on heat/cook setting “1”. Was done nicely, (not soupy, even with the extra liquid). Everyone liked this.
Next time I might add 3-4 extra eggs.
Robyn says
I love all the ingredients in this recipe and prepared overnight for Christmas morning. I followed the recipe exactly, with some extra seasoning, and my family found it pretty bland. We had to season heavily to eat and the kids weren’t fans. I like crispy hash browns, which these definitely aren’t. I’m glad others enjoyed! It simply wasn’t our taste at all and the leftovers will not be eaten.
Richard Gamble says
I did not make this, yet, but have had variations of this recipe over the years. This one looks much better because it has peppers and you can almost never go wrong cooking things in the crock pot. But, I would definitely say to have 8 people over to eat it all while it's right out of the crock pot because the refrigerated leftovers are never quite as good as the fresh, hot meal.
Tedi says
I’m definitely making this for Christmas breakfast! Only question I have is are the hashbrowns frozen or thawed
Marye says
either way.
Judi Schafman says
Oh that looks sooo good. May try this on Christmas morning instead of my old recipe
Pam says
In our newspaper today, there were recipes to make breakfast casseroles that you refrigerate overnite. This one is better-it cooks while you're sleeping! I don't have
company for breakfast, but will have for "brunch" and this will be perfect!
Thanks

I love Breakfast casseroles for dinner. I think I'll use sweet Italia sausage and make it for dinner on the 26th.

This casserole has saved Christmas lunch many times, it's not only delicious but it makes the whole house smell so good! It's been requested by seven of the guests staying here for Christmas again. Sure makes my life simpler.
Janet Martin says

Sue Turcsany says
Have made similar breakfast casseroles but always baked in the oven. Didn't really think that eggs would work well in the crockpot, but if you say it does, I'll give it a try---looks delicious and easy.
