This overnight crock pot breakfast casserole makes getting out of bed worth it—your hearty, nutritious breakfast cooked to perfection in the slow cooker while you slept! Hash brown potatoes, eggs, and ham team up in this breakfast casserole along with lots of shredded cheddar cheese and seasonings. 

Chopped green onions and red and green bell peppers season the easy crockpot casserole. Mild chile peppers may be used as well, or change it up even more with some Tex-Mex seasonings. Feel free to tailor the casserole to suit your family's tastes. Serve this tasty crock pot egg casserole with buttered toast or biscuits and sliced tomatoes or fresh fruit for a fabulous breakfast. With the festive look of the multicolored peppers, the dish is a great choice for the holiday mornings.

The recipe calls for refrigerated hash brown potatoes, but partially thawed hash browns are good, too, and they might even help extend the cooking time slightly. See the tips and variations for how to thaw frozen hash browns and some additional ingredient ideas.

  7. Pour the egg mixture over the cheese; it will sink into the potatoes.

  • If you use frozen hash browns, thaw them in the refrigerator for a few hours or put them in a colander and partially thaw them under cold running water. Pat them dry with paper towels before adding them to the recipe. Ensure they are thawed enough to break apart into shreds.

Recipe Variation

  • Add 1 small can of mild chile peppers along with the bell peppers and green onions.
  • Replace the cheddar cheese with cheddar jack cheese or a Mexican blend, pepper jack, or taco seasoned cheese.
  • Add a cored, seeded, and chopped tomato to the layers.
