Easy High Protein Breakfast Casserole with Diced Potatoes
This breakfast casserole with diced potatoes is an amazing tool to use on many occasions from meal prepping for busy mornings to hosting a large gathering for breakfast or brunch. This is a deliciously savory and hearty meal that is perfect for fueling your day with good quality protein!
When to Serve a Breakfast Casserole
Breakfast casseroles are perfect for serving a large crowd. You may find they work well for Easter, Christmas or Thanksgiving morning when there are many people gathered together. Making a breakfast casserole allows you to enjoy your company and still serve a delicious meal!
If you grow or buy bulk produce to preserve by canning, you know canning days can be long. Preparing a breakfast casserole the night before a big canning day can resolve the sometimes cumbersome task of preparing a meal on that long day. Since this breakfast casserole will be filled with lots of good, filling protein, you will be energized to keep going all day!
Baking a breakfast casserole ahead of time is also an excellent option for meal prepping! Once the casserole is completely cooked, it’s easy to divide into daily portions to heat and take on the go or heat whenever you need it.
Sides to Serve with a Breakfast Casserole
Although a breakfast casserole tends to be pretty hearty due to the higher protein content, it can be nice to include side offerings when you’re hosting a breakfast or brunch. Many people will find that any kind of pastry works well. Any seasonal fruit or yogurt is also delicious to include in your spread to make a well rounded meal.
Substitutions
One of the best things about breakfast casseroles is that the ingredients are extremely flexible. Any combination of meat and vegetables mixed into a base of whisked eggs and some seasonings is likely to turn out delicious.

Other Additions
Since there are practically endless combinations of ingredients for making a breakfast casserole with diced potatoes, this recipe does not include all of the possible ingredient options. Depending on your dietary restrictions or preferences, the below are just a few items that you can include in addition to what is listed in the written recipe. When choosing different additions, be mindful about how much of each ingredient you use and how much your making dish can carry. With all of the options, it’s easy to over fill.
Meats – bacon, a second flavor of ground sausage, sausage links and turkey bacon pieces.
Cheeses – cheddar, parmesan, goat cheese, herbed cheese, gouda and blue cheese.
Vegetables – chopped spinach, broccoli, tomatoes, zucchini (chopped or shredded), shredded hash browns, mushrooms, bell pepper and diced sweet potatoes.
Fresh Herbs- Chives, basil, parsley, oregano, garlic, rosemary, thyme and dill.
Preparing a Breakfast Casserole With Diced Potatoes Ahead
Preparing breakfast casserole ahead of a hosting event is an excellent idea. Doing so will eliminate a large majority of the mess that is normally made by preparing food. Additionally, this will allow you to spend more quality time with your guests instead of cooking and cleaning.
To ensure the freshest possible flavors, I suggest cooking/premixing the components no more than 2 days ahead of serving. If you want to prepare as much as possible ahead, I suggest cooking the meat, potato and onion mixture first. Instead of adding it to your glass baking dish, add it to a glass container with an airtight lid. Let the meat and veggies cool before securing the lid and storing in the refrigerator. Similarly, you can whisk the eggs and spices together and store in an airtight glass container. Canning jars are fantastic to store mixed eggs. Canning jars also make it really easy to pour the egg mixture.
Breakfast Casserole With Diced Potatoes Ingredients and Tools
12 Eggs
1 Medium Onion, finely diced
3 cups Small Diced Potatoes
1 Lb Breakfast Ground Breakfast Sausage
1 tsp Salt – I like to use Redmond Real Salt to add extra minerals
1/2 tsp Pepper
2 tsp Garlic Powder
2 tsp Parsley
9×13 glass baking pan
Medium bowl
Whisk or fork
Directions
Preheat your oven to 350℉.
While the oven is preheating, start browning the ground sausage in a pan on the stovetop on medium-low heat.
When about half of the meat has cooked, add the diced potatoes and onion to the meat to begin the cooking process. Season the potatoes with salt an pepper. Since potatoes take longer to cook than eggs, this will help ensure the potatoes become fully cooked when baking in the oven. The onions will also develop a more caramelized flavor.
While the potatoes and onions begin to cook, crack all 12 eggs to a medium bowl. Whisk together with salt, pepper, garlic powder and parsley.
Oil your 9×13 glass baking dish with your desired cooking oil (I like butter, tallow, lard or coconut oil).
When the breakfast sausage is fully cooked, transfer all ingredients from the stovetop to the baking dish. Pour the seasoned eggs over the meat and vegetable mixture.
Place in the oven for 25-30 minutes or until the eggs are fully cooked.
Remove from the oven and let cool for 5 minutes before serving.
