This Crockpot Breakfast Casserole cooks overnight so you can wake up to a hearty potato casserole oozing with cheese without all the work!
You guys, I can’t (and won’t) stop adapting recipes for my slow cooker. I’m obsessed.
This crockpot breakfast casserole is a delicious twist off of my ham and cheese breakfast casserole. It’s perfect for holiday or weekend brunches or for easy weekday breakfasts. It’s quick, simple, makes a TON, and oh yeah, is SO DELICIOUS!
A hearty breakfast casserole made with a few frozen items, pantry staples, eggs, and cheese!
- Potatoes O’Brien – frozen potatoes with onions and peppers. The onions and peppers add a ton of fresh flavor.
- Breakfast Sausage Links – use mild, medium or spicy, frozen fully cooked breakfast sausage links.
- Black Beans – for some delicious, healthy protein.
- Pepperjack Cheese – adds some creaminess and spice.
- Cheddar Cheese – gives the casserole a nice, sharp flavor.
- Eggs – creates a fluffy casserole that’s packed with protein!
- Evaporated Milk – makes it extra creamy and provides a hint of sweetness.
- Green Chiles – gives the casserole a mild heat!
- Salt, Chili Powder, Cumin, Garlic Powder, and Pepper – the perfect spice blend for some serious tex-mex flavor.
- Sour Cream, Cilantro, Pico de Gallo, and Salsa – for serving!

How long do you cook breakfast casserole?
Breakfast casserole cooks in the crockpot on HIGH for 4 hours or LOW for 8 hours.
Prep this the night before, let it cook overnight, then enjoy it in the morning! If you’re pressed for time, or planning a breakfast for dinner meal, cook on high instead!
Can breakfast casserole be baked?
- Preheat oven to 350 degrees F and grease a 9×13 inch baking dish with cooking spray.
- Combine the ingredients as listed in the recipe then pour the mixture into the prepared pan.
- Bake, uncovered, for about 1 hour – 1 hour 15 minutes, or until the eggs have set and the potatoes are tender. (*not tested)

Is breakfast casserole gluten-free?
This crockpot breakfast casserole is gluten free, but other recipes may not be. This casserole uses potatoes and other ingredients that are naturally gluten free, but many breakfast casseroles use bread, which unless noted, are not gluten free.
As always, make sure you check all of your ingredients to verify that they are gluten-free before using in your casserole.
This breakfast casserole is perfect just the way it is, but here are some ways you can change it up if you’re looking for some different flavors and textures.
- Add veggies. Try adding in extra diced peppers and onion. Sauté them until tender before placing them in the crockpot for the best texture. I don’t recommend adding other veggies, because it might make the dish too watery.
- Try different cheeses. Mozzarella, gouda, swiss, monterey-jack, provolone, gruyere, you name it! Top with crumbled feta for extra tang and creaminess!
- Play around with the spices. Use your favorite spice blend!
- Sub the meat. Sub the sausage for some cubed ham or try my ham and cheese breakfast casserole!
- Use different potatoes. Not a fan of peppers and onions? Replace the potatoes o’brien with frozen diced hash browns instead.
- Make vegetarian. Swap the sausage with vegetarian sausage!
- Spice it up. Add some red pepper flakes to go with the green chiles or top the final dish with your favorite hot sauce!
There’s literally nothing you can do to make this taste bad. It’s just THAT good. 😉
