Sausage Breakfast Casserole Ingredients
You’ll need:
- 5 cups potatoes O’Brien, thawed
- 1 tablespoon butter
- 1 pound mild sausage
- 3 green onions
- 32 ounces Egg Beaters Original or 14 eggs
- ¾ cup milk
- ½ teaspoon black pepper
- 1½ teaspoons salt (or omit the regular salt, garlic & onion powders and replace it with 2 teaspoons of seasoned salt)
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- 1 (10-ounce) can RO*TEL Original Diced Tomatoes and Green Chilies
- 2 cups shredded cheddar and Monterey Jack cheese blend
PRO TIP:
The 5 cups of potatoes is equal to 1 (32-ounce) bag of frozen diced potatoes. If you cannot find “O’Brien” potatoes, you can add ½ cup diced red bell pepper and/or green bell pepper and 1 cup of diced onions to the skillet to cook with the sausage.
SUBSTITUTIONS AND ADDITIONS
GREEN ONIONS: You can omit the green onions and add 1 cup of diced yellow onions to the breakfast sausage as it cooks and crumbles.
SPICE: Spice up this easy breakfast casserole recipe with pepper Jack cheese. A dash of hot sauce will also give you an extra kick.
SAUSAGE: Any sausage will work for this easy recipe depending on your preference. Pork sausage, spicy hot sausage, or mild sausage would all work.
How To Make This Sausage Breakfast Casserole Recipe
STEP ONE: Preheat the oven to 350°F and grease a 9×13 casserole dish with 1 tablespoon of butter. Set aside.
STEP TWO: To thaw the potatoes, measure out 5 cups and place them in the fridge until thawed. Or to thaw quickly, place in a microwave-safe bowl. Cook on 50% power for 2 minutes at a time until they are just thawed (they should still be slightly cool, you don’t want to cook the potatoes). Set aside.
STEP THREE: In a medium skillet over medium-high heat, break up the ground sausage and cook until the sausage is brown and cooked through. Turn off the stove, remove the pan from the heat and let the sausage cool slightly.
PRO TIP:
PRO TIP: If you are substituting diced yellow onions for green onions, you can cook them with the sausage in the skillet.
STEP FOUR: Transfer the cooked sausage to a paper towel-lined plate to absorb the excess fat from the sausage before combining it with the microwaved potatoes. Make sure to mix well as this will ensure that you have an even distribution of both sausage and potatoes.
STEP FIVE: In a medium mixing bowl, pour in the eggs, milk, salt, pepper, garlic powder, and onion powder. Drain the tomatoes and add to the mixture.
STEP SIX: Chop the whites and greens of the green onions and add to the egg mixture. Then stir in the shredded cheese.
STEP SEVEN: Layer the sausage on top of the potatoes and pour the egg mixture on top, spreading it out evenly. Shake the pan just a little bit so it settles in between the potatoes.
STEP EIGHT: Bake in the preheated oven for 1 hour and 15 minutes until brown and the center is no longer jiggly. Check at the 45-minute mark to see if it is getting too brown. If so, tent it with a piece of foil.
STEP NINE: Remove from the oven and let sit for 20 minutes before serving.

Martha paiz says
If I donโt use the egg beater. How many eggs can I use.
Layne Kangas says
Hi, Martha – I haven’t done it using eggs instead. Google is telling me it’s one egg for every 1/4 cup of Eggbeaters, so I think that would be about 16 eggs. Enjoy!
Julie says
This was so good. Adding it to my favorite recipe book
Diane Lamain says
This recipe was easy to follow and didnโt require a lot of time to prepare. It was such a hit with my breakfast guests. You could easily customize it with a spicy sausage, hot peppers, or favourite veggies like mushrooms. I will definitely make this one again!
