The Key Ingredients in this Cheesy Potato Breakfast Casserole

The magic of this dish lies in its simple, accessible ingredients. Here’s what you’ll need to create this breakfast masterpiece.

For the Potato Base

• Potatoes: We recommend Russet or Yukon Gold potatoes for their fluffy texture when baked. You can also use red potatoes, but the texture will be slightly waxier.
• Olive Oil: Used to roast the potatoes, giving them a crispy exterior.
• Seasonings: A simple mix of garlic powder, onion powder, smoked paprika, salt, and black pepper gives the potatoes an incredible flavor foundation.

For the Egg & Sausage Filling

• Breakfast Sausage: A pound of your favorite breakfast sausage adds a hearty, savory element. You can use mild, hot, or even a maple-flavored variety.
• Eggs: The star of any casserole, providing a fluffy, custardy binder for all the ingredients.
• Milk & Heavy Cream: A combination of milk and heavy cream creates the richest, most tender egg custard. Whole milk is preferred for the best texture.
• Cheddar Cheese: Sharp cheddar cheese provides the best flavor and a glorious cheese-pull. Feel free to substitute with Monterey Jack, Colby, or a blend.
• Green Onions: For a mild, fresh onion flavor that cuts through the richness of the casserole.

How to Make Potato Breakfast Casserole Step-by-Step

Making this casserole is incredibly simple. Just follow these steps for a perfect result every time.

1. Prep Your Potatoes: Start by dicing your potatoes into uniform ½-inch cubes. Toss them with olive oil and seasonings until they are evenly coated.
2. Roast the Potatoes: Spread the seasoned potatoes on a baking sheet in a single layer. Roast at 400°F (200°C) for 20-25 minutes, or until they are tender and lightly browned. This step is crucial for ensuring the potatoes are perfectly cooked in the final casserole.
3. Cook the Sausage: While the potatoes are roasting, cook the breakfast sausage in a large skillet over medium-high heat, breaking it apart with a spoon, until it’s browned and cooked through. Drain off any excess grease.
4. Assemble the Casserole: Grease a 9×13-inch baking dish. Layer the roasted potatoes evenly across the bottom, followed by the cooked sausage. Sprinkle half of the shredded cheddar cheese and most of the sliced green onions over the top.
5. Prepare the Egg Mixture: In a large bowl, whisk together the eggs, milk, and heavy cream. Season with a bit of salt and pepper. Pour this mixture evenly over the layers in the baking dish. Top with the remaining cheese.
6. Bake to Perfection: Bake at 375°F (190°C) for 35-45 minutes, or until the eggs are set and the top is golden brown and bubbly. You can check for doneness by inserting a knife into the center; it should come out clean.
7. Rest and Serve: Let the casserole rest for about 10 minutes before slicing. This allows it to set up properly. Garnish with the remaining green onions and serve warm.

Expert Tips and Variations

Tips for Success

• Don’t Skip Roasting the Potatoes: Pre-roasting the potatoes guarantees they will be tender and flavorful, preventing any hard, undercooked bites in your casserole.
• Shred Your Own Cheese: For the best melt, buy a block of cheese and shred it yourself. Pre-shredded cheeses often contain anti-caking agents that can affect the texture.
• Let It Rest: Allowing the casserole to rest for at least 10 minutes after baking is key. This helps it set, making it much easier to slice and serve clean portions. Speaking of potatoes, if you’re a fan, you might also love our creamy scalloped potatoes recipe.

Easy Variations

• Different Meats: Swap the sausage for cooked and crumbled bacon, diced ham, or even chorizo for a spicy kick. For a similar hearty meal for dinner, our Tuscan sausage and potato soup is a fantastic choice.
• Add More Veggies: Feel free to add sautéed onions, bell peppers, mushrooms, or spinach for extra flavor and nutrients. Just be sure to cook them before adding them to the casserole to remove excess moisture.
• Spice It Up: Add a pinch of red pepper flakes to the egg mixture or use a spicy sausage for a bit of heat. A dash of hot sauce on top when serving is also delicious.

How to Store, Reheat, and Freeze

This Potato Breakfast Casserole is just as delicious the next day, making it perfect for leftovers.

• Storage: Cover the cooled casserole tightly with plastic wrap or transfer individual slices to an airtight container. Refrigerate for up to 4 days.
• Reheating: For best results, reheat individual slices in the microwave for 1-2 minutes or until warmed through. You can also reheat the entire casserole in an oven preheated to 350°F (175°C) for about 20 minutes, or until hot.
• Freezing: To freeze, allow the casserole to cool completely. You can freeze it whole or in individual portions. Wrap it tightly in plastic wrap, followed by a layer of aluminum foil, and freeze for up to 3 months. Thaw in the refrigerator overnight before reheating.
