Crockpot recipes are great on busy mornings, but they're even better for Christmas morning breakfast.
This overnight crockpot breakfast casserole handles all the cooking time for you, so you won't miss a festive minute of the whole family gathering joyfully around the tree.
🧾 Ingredients
This is an overview of the ingredients. You'll find the full measurements and instructions in the green recipe card (printable) at the bottom of the page.
🔪 Instructions
This is an overview of the instructions. Full instructions are in the green recipe card at the bottom of the page.
- Whisk the eggs, milk, salt, and pepper together in a large bowl.
- Lay 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.
🥫 Storage
This crockpot breakfast casserole recipe usually doesn't 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.
📖 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.
- Ground sausage gives the best texture in my opinion, but you could thinly slice some breakfast sausage links and use those for faster prep.
- Stir in bacon bits—it takes a great breakfast to a perfect breakfast!
- 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.
💭 Things to know
Expert Tip: 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.
- 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 as much air as possible into the eggs.
- Want breakfast now? Prepare as directed, layering the ingredients into a large skillet. Bake at 375 degrees F for about 30 minutes, or until the eggs are cooked all the way through.
👩🍳 FAQs
Oh, you are in for a treat! Classic breakfast casserole is made of layers of potatoes, sausage, and cheese, then it's all covered with an egg and milk mixture, which bakes up to savory perfection. The best thing about crockpot breakfast recipes is that they taste just like eating all of the wonderful breakfast foods, without a ton of stressful prep work!
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.
