Just put it in the slow cooker, go to sleep while it’s cooking, and serve it up in the morning! Consider getting a programmable crock pot with a timer. That way, you don’t have to worry about getting distracted or oversleeping and overcooking!

What to Serve with Crockpot Breakfast Casserole

  • Serve it with lots of fresh toppings like avocado, cherry tomatoes, red onions, sour cream, salsa, or hot sauce.
  • If you’re trying to stretch it a little bit for a crowd, you can also serve it with fresh fruit or a simple fruit salad, like this one.
  • Toast, bagels, muffins, or English muffins would also make excellent sides and fill everyone up a little more.
  • I love to serve it as a buffet with fruit, maybe biscotti or scones, and juice and coffee.

How to make Slow Cooker Breakfast Casserole: 

  • Cook the bacon in small pieces, and save a few whole pieces for the top.
  • Mix the eggs with green chilis and milk.
  • Layer the ingredients (hash browns, bacon, cheese, red onion, peppers, and cheese). Pour the egg mixture. Top with whole slices of bacon.
  • Don’t forget the toppings: sour cream, salsa, and green onions.
  • Make the night before; cook through the night. Wake up to a delicious breakfast, ready to serve with sour cream and fresh salsa.

Extra tips:

COOKING: Not all slow cookers cook at exactly the same temperature. You may need to adjust the cook time to avoid overcooking.

HASH BROWNS: Use frozen hash browns or you can make your own. Only use Yukon Gold potatoes (do not use Russet potatoes) if you make your own.

ADDITIONS: Add other meats like diced ham or other veggies like mushrooms or spinach.

This recipe is the best when topped with LOTS of fresh toppings such as sour cream, tomatoes, salsa, avocado, green onion, or chives.

LEFTOVERS: Scoop out a serving and pop it in the microwave.

Can you freeze it? No! Eggs do not freeze well.

Lastly, as we move into the week of Thanksgiving, I love this quote so much.

“Do not spoil what you have by desiring what you have not; remember that what you now have was once among the things you only hoped for.” —Epicurus

Happy weekend and ENJOY!
