It’s a slow cooker breakfast casserole that will soon become a family favorite for holiday breakfasts and brunches!
Tips on how to make a crockpot breakfast casserole
There are a few tricks to making the best crock-pot breakfast casserole.
Spray or line your crock: First, make sure to spray the inside of your crockpot with non-stick cooking spray or line with a slow cooker liner for easy cleanup.
If you don’t want to do any precooking, use ham or a precooked sausage. Make sure to cut the sausage into bite-sized pieces.
Drain off any grease from the cooked sausage or bacon. Then blot cooked sausage and bacon with paper towels so the crockpot breakfast casserole doesn’t end up too greasy
Chop up bacon into smaller pieces and set all the meat aside.
Then follow the recipe as directed below.
How do you know when your breakfast casserole is done?
Cooking for 3-4 hours on high or low for 7-8 hours should be plenty of time to cook the eggs properly.
The eggs shouldn’t be runny. And the cheese should have melted nicely.
The edges of the breakfast egg casserole should be nice and brown.
How to serve: Spoon up this tasty breakfast casserole with guacamole, salsa and sour cream. Add a little hot sauce, too!
Making this crock-pot breakfast casserole even easier
Veggies: Chopping vegetables can take a lot of time. Luckily, you can buy already chopped fresh peppers in the produce area of your grocery store.
Or you can use frozen three pepper and onion blend instead of fresh peppers and green onions.
This is my favorite thing to do since you can keep a supply of frozen peppers along with frozen hash browns so you can make this breakfast casserole anytime!
Cheese: Buying shredded cheese, instead of shredding your own, also makes this a easy to make crock-pot breakfast casserole.
Eggs: You can use liquid whole eggs instead of whole eggs. Check the label to find how much liquid eggs you’ll need.
You can also do a combination of liquid whole eggs and liquid egg whites if you wish for a much more healthy crockpot breakfast casserole.
Breakfast casserole in crockpot variations
Hash browns: While this is a crockpot breakfast casserole with hash browns, you can substitute tater tots if you wish. Just make sure not to make the tot layer too thick.
Use different types of cheese: Try other types of cheese, instead of cheddar or Colby-Jack. Try a Mexican blend, Italian blend, Monterey Jack, and so on.
Vegetables: You can use other vegetables like zucchini, squash, and tomatoes instead of peppers.
Mexican style: Try Crockpot Taco Meat instead of sausage. Substitute salsa for the mustard and use shredded Mexican blend cheese for a Mexican breakfast casserole.
Just note that some vegan cheeses do not melt as well as regular cheeses.
Perfect for potlucks: After cooking, wrap your slow cooker in an insulated carrier bag to bring to a brunch potluck.
