How to make Crockpot Breakfast Casserole

This Crockpot Breakfast Casserole is perfect for meal prep, and if you store it correctly it's a grab and go breakfast!

You don't have to worry about what you're going to eat in the morning and you can also take it with you to go, so you can eat it at work instead of wolfing down some food first thing in the morning before you're even hungry.

Here's how to make this breakfast casserole:

Cook the bacon over med-high heat in a large skillet, about 5-10 minutes until cooked through (timing will depend on type of bacon used – I use turkey bacon to keep it lower in calories).
Spray inside of slow cooker with cooking spray, then add frozen hashbrowns, cooked bacon, peppers and onion in two even layers.
Mix salt and pepper with eggs, then pour overtop of other layers and top with cheese.
Cook on high for 4 hours. Serve and enjoy!

Breakfast Casserole Ingredient Substitutions

The great thing about this crockpot breakfast casserole is that you can put just about anything in it!

Because I'm obsessed with hash browns, they had to make an appearance – I just used the frozen diced breakfast potatoes that McCain makes but you could layer in some tater tots or shredded frozen potatoes too. From there, you'll pile in the veggies and your protein.

Cooked up breakfast sausage works as well as turkey bacon or regular pork bacon. You can even get creative and use up some leftover meat if you have any in the fridge. Leftover ham, for instance would work well, or even some deli turkey, salami or ham would taste amazing.

I just used some diced up bell peppers and red onion and then added in some cheddar cheese to top it all off but even the cheese is optional! If you're really in a bind you can just throw some spinach in there too and skip the other veg. Don't be afraid to mix it up!

Making breakfast casserole in the oven

This Crockpot Breakfast Casserole is SO simple to make!

You can technically even make it in the oven too – like you would in the slow cooker, spray an oven-safe dish with cooking spray and then layer in all your ingredients. Pour the eggs and cheese overtop, then bake!

If you're going to bake this breakfast casserole, make sure you preheat the oven to 350 F and cook for 45 min to 1 hour.

Otherwise, let the crockpot do all the work! All you need to worry about ahead of time is prepping your protein, so fry up your bacon or sausage and dump it in with the rest of the ingredients. I sometimes cook the meat a day or two before so it's easy to just cook everything when it's time.

Making this Crockpot Breakfast Casserole ahead

Part of what I love about this slow cooker breakfast casserole is that you can make it a few days in advance. If you're celebrating something special and want to have everything cooked before guests arrive, you can have this breakfast casserole going a few days before. And it will last in the fridge up to 5 days so it's also perfect for your weekly meal prep.

If you are going to be entertaining and want this crockpot breakfast casserole to be ready fresh, you can plan the timing accordingly so it finishes up just as everyone arrives. If you have a brunch around noon or 1pm for instance, you can cook this breakfast casserole on high for 4 hours starting at 8 or 9am so you will have time in the morning to get everything together.

You can also assemble the night before – you just need to keep the crockpot in the fridge so the ingredients don't go bad.

Storing and reheating

You can store this breakfast casserole in the fridge up to 5 days. I recommend storing individual portion sizes in glass meal prep containers so that all you have to do is take one out of the fridge and reheat for 2-3 minutes. Sprinkle a little bit of water overtop before reheating to ensure it doesn't dry out, and the leftovers will taste just like new!

Freezing this recipe

You can also freeze the cooked leftovers! Store individual portions in glass containers with lids. You can reheat in the microwave straight from frozen. Sprinkle a bit of water overtop then reheat for 6-7 minutes, checking on it halfway through the cooking time.
