Mother’s Day weekend is upon us, and fast, delicious brunch options are a must! Especially, if you’re the mom doing the cooking this weekend! This Easy Hash Brown Breakfast Casserole is so tasty, satisfying, and filled with all the best things. It comes together in a snap, and makes enough for a crowd!

You just can’t go wrong with sausage and peppers, those flavors are a match made in heaven. My husband is a bit of a carnivore, so I made this breakfast casserole with 2 kinds of meats. That’s the great thing about this recipe, you can add in whatever meats, vegetables, or cheeses you have on hand! We made it with ham, sausage, cheddar, and onion in the photos.

Preparing the Ingredients

You simply need to take a few steps before getting started:

  • Thaw the hash brown potatoes in the fridge overnight
  • Dice a red or green bell pepper and half a medium yellow onion
  • Brown the breakfast sausage over medium heat with the diced onions and peppers (don’t forget to drain the fat), set aside
  • If using, dice or slice some leftover ham (or deli ham)
  • Whenever possible, shred the cheese by hand instead of buying pre-shredded. It really makes the cheese melt so much easier, and the cheese goes further in the dish. Not to mention, it makes the cheese texture much creamier too!

Assembling the Hash Brown Casserole

Preheat the oven to 375 degrees. Lightly spray the baking dish with non-stick cooking spray. Add the prepared meat and vegetable mixture to the pan with the thawed potatoes.

Next, add 1.5 cups of shredded cheese, and stir all of the ingredients together to combine.

Whisk the milk and 12 eggs together. Season with ground mustard and salt and pepper. Pour the eggs over the meat, vegetables, and potatoes.
