This breakfast casserole is made in the Crockpot or slow cooker and is super versatile, making it perfect for entertaining, the holidays, or Christmas morning. With hashbrowns, eggs, onions, cheese, and your protein of choice (with vegetarian options!), it’s loaded with flavor and is so easy and quick to make.
Why This Casserole is So Good
- This breakfast casserole is so quick and easy to make, you just have to fry the bacon and then dump everything in the slow cooker.
- You can easily make this casserole vegetarian.
- You can set this casserole overnight for an easy to grab breakfast in the morning.
How to Make This Recipe
- Cook the diced bacon until crisp. Drain and set aside.
- Spray the sides and bottom of Crockpot. Spread half of the hash browns in the bottom then sprinkle over half of onions, then half of the cheese, then half of the bacon. Repeat with the remaining ingredients: hash browns, onions, cheese, bacon.
- In a medium bowl, whisk eggs with half-and-half, salt, garlic, black Pepper. Pour eggs over. Low 8-9 hours
Such an Easy Overnight Recipe
This casserole is perfect if you have overnight guests that need feeding in the morning. It takes around 8 to 9 hours to cook the casserole in the slow cooker, so pop everything in just before you go to bed and you will wake up to a ready to serve hot breakfast.
Variations
I love this recipe, as it’s so easy to adapt it to different tastes and diets.
- You can use 1 pound of breakfast sausage in place of the bacon. Brown and crumble the breakfast sausage then drain and continue with the recipe as written.
- It’s so easy to make this Crockpot breakfast casserole vegetarian. You can simply omit the bacon, or you could substitute it for vegetarian bacon or sausage.
- If you prefer, you can use non-dairy milk or half-and-half. I like Ripple’s Half and Half.
How Long Does It Keep?
This is such a great make-ahead breakfast, not only can you cook it the night before serving, but it also stores well too. Transfer the cooked casserole to an airtight container and it will keep well in the fridge for about three to four days and then you can reheat it in the oven.
Top Tips For Making
- When sprinkling on the cheese, leave a slight border from the sides of the crockpot. This will prevent as much burning of the edges as possible
- There will be SOME burning on the edges but it won’t affect the rest. just leave a small border when cutting into the casserole to serve
- You must spray the crockpot first. this dish cooks for quite a long time and will burn or stick otherwise

Any ideas on how many crockpots I would need to feed approx 75 people? This is my first time feeding a group this large.
As written, this casserole yields approximately 10 servings, so you’d need 7-8 casseroles for that number of people, depending on the size of your servings. You may be able to use a larger Crockpot with 1.5-2x the ingredients so you don’t need to make as many casseroles, but we haven’t tested it so we can’t say for sure what size you’d need or how much of each ingredient. If you’ve got time between now and your event, I recommend making a test casserole to get a better idea of what you’ll need!
Can I use regular milk instead of half and half? Really want to make, but only have regular milk! Thanks!!!
So glad you enjoyed it! 🙂
Hi, I have a 3.5 qt casserole crock pot. I’m presuming I can easily halve the recipe, but how would it impact cooking time?
You can cook on low for 4-6 hours and see how that works! You can always cook longer if needed. 🙂
Would full fat coconut milk work ok? I want to try this as a Whole30 compliant version (sadly w/o cheese).
Sure! Let us know how it goes! 🙂
Can you use corned beef instead?
We’ve never tried that, but it sounds like it could work!
If I wanted to make this in my crockpot instapot how would I do that?
Hi 🙂 Do you mean you would like to cook it in the Instant Pot?
