The Key Ingredients
Sausage: The Star Protein
The choice of sausage can define the flavor profile of your casserole. Whether you prefer spicy breakfast sausage, mild turkey sausage, or a plant-based alternative, this ingredient adds richness and depth.
Potatoes: The Hearty Base
Potatoes are the backbone of this dish, providing a starchy, satisfying texture. You can use frozen hash browns for a quick shortcut, or dice fresh potatoes for a more rustic touch. Either way, they serve as the perfect foundation for the layers of flavor to come. You can even swap regular potatoes for sweet potatoes for a healthier twist.
Eggs: The Binding Agent
Eggs are essential for holding the casserole together and adding fluffiness and structure. Whisking the eggs thoroughly with milk creates a creamy egg mixture that evenly coats all the ingredients, ensuring every bite is delicious.
Cheese: The Creamy Element
A combination of sharp cheddar cheese and Monterey Jack cheese gives the casserole its gooey, melty finish. You can experiment with different cheeses like Swiss, mozzarella, or even a bit of feta for variety.
Step-by-Step: How to Make Sausage and Egg Breakfast Casserole with Potatoes
Ingredients

- 1 lb breakfast sausage (or turkey sausage, plant-based sausage)
- 6 large eggs
- 1 cup milk
- 3 cups potatoes (diced or shredded hash browns)
- 1 cup shredded cheddar cheese
- 1/2 cup Monterey Jack cheese
- 1 bell pepper, diced (you can use red pepper for extra color)
- 1/2 cup onions, chopped
- 1 tsp onion powder
- 1/2 tsp garlic powder
- Salt and pepper, to taste
- Olive oil or non-stick spray for greasing the baking dish
Instructions
- Preheat the Oven
Set your oven to 375°F (190°C). Grease your baking dish with olive oil or cooking spray to prevent sticking. - Brown the Sausage
In a large skillet, cook the breakfast sausage over medium heat until browned and fully cooked. Remove from the skillet and set aside. - Prepare the Vegetables
Using the same skillet, sauté the diced potatoes, onions, and bell peppers (or red pepper) until they are tender. Season with onion powder, garlic powder, salt, and pepper. - Assemble the Egg Mixture
In a large bowl, whisk together the eggs, milk, and a pinch of salt and pepper until fully combined. - Layer the Ingredients
In the greased baking dish, layer the sautéed potatoes and vegetables at the bottom, followed by the cooked sausage. Pour the egg mixture evenly over the layers. - Add the Cheese
Sprinkle shredded cheddar cheese and Monterey Jack over the top for a gooey, melty finish. - Bake
Pop it in the oven and bake for 35-40 minutes, or until the eggs are fully set and the top is golden brown. - Cool and Serve
Let the casserole cool for 5-10 minutes before slicing into portions and serving.

Tips for Perfect Results
- Use Fresh Ingredients
Fresh potatoes, eggs, and sausage make a noticeable difference in flavor and texture. - Don’t Overbake
