A simple mixture of breakfast sausage, bell pepper, and cheeses mixed with potatoes and mild green chiles. It’s all topped with an egg mixture and baked until browned and bubbly. Loaded with everyone’s favorites, it makes a great breakfast or dinner and reheats well for quick meals throughout the week.

Easy Breakfast Casserole

Make and bake right away or… make-ahead, cover, and bake the next day! No-fuss, no muss! Just like a shredded hashbrown breakfast casserole, versatile so you can add in your favorite veggies or even leftover taco meat! Save time and use precooked sausages or pre-cooked bacon. Frozen hashbrowns can be found with onions and bell peppers already mixed in, too!

Ingredients & Variations

Use either bulk sausage or breakfast sausage links (even turkey sausages will work). No sausage? Add cooked bacon pieces or even Italian sausage! Red bell peppers are colorful and while mild green chiles add flavor, but this casserole is a great vehicle for other vegetables too. Sliced mushrooms, fresh chopped spinach, leftover roasted veggies, or even a bag of frozen peppers and onions can be added to the casserole. Frozen diced potatoes make this quick and easy. If you’d like to use your own fresh potatoes, peel and dice 1/2-inch. Cook the diced potatoes (either boil, roast, or panfry) until tender. Shredded hashbrowns work too. Eggs and milk give a light fluffy texture and hold everything together. Cheddar and pepper jack are bold and delicious. They pair well with the flavors in this recipe but almost any shredded cheese works. While I usually recommend shredding your own cheeses, pre-shredded work well in this recipe (and save time!).

Tips for the Best Breakfast Casserole

Use large eggs and whisk well. If adding other vegetables, be sure to pre-cook any that have a lot of water (like mushrooms). Remove the casserole from the fridge while the oven preheats. After baking, let the casserole rest for about 10-15 minutes before cutting into squares and serving.
