Key Ingredients to Keep on Hand

- Eggs: The binder of the casserole, eggs help hold everything together while adding richness.
- Cheese: Sharp cheddar is classic, but feel free to mix it up with Monterey Jack, mozzarella, or pepper jack for extra flavor.
- Breakfast Meat: Cooked sausage, bacon, or ham add a smoky, savory element that complements the creamy potatoes and cheese.
- Onions and Peppers: Optional but highly recommended for added sweetness and color.
- Milk or Cream: Adds moisture and creaminess to the egg mixture.
- Seasonings: Salt, pepper, garlic powder, and paprika help elevate the flavors.
Step-by-Step Guide to Making Cheesy Potato Breakfast Casserole
Step 1: Prep Your Ingredients
If using raw potatoes, peel and dice them into bite-sized pieces. If you prefer shredded potatoes, frozen hash browns are a convenient shortcut. Cook your chosen breakfast meat until browned and crispy, then drain excess fat. Chop onions and bell peppers if using.
Step 2: Layer the Casserole
Grease a 9×13-inch baking dish. Spread half the potatoes evenly on the bottom. Layer half the cooked meat over the potatoes, then sprinkle with half the chopped onions and peppers. Add a generous layer of cheese on top. Repeat the layers with the remaining potatoes, meat, onions, and cheese.
Step 3: Mix the Egg Mixture
In a large bowl, whisk together eggs, milk or cream, salt, pepper, garlic powder, and paprika until well combined. Pour the egg mixture evenly over the layered casserole.
Step 4: Bake Until Golden and Set
Preheat your oven to 350°F (175°C). Cover the casserole loosely with foil and bake for 40 minutes. Remove the foil and bake for an additional 15-20 minutes until the eggs are set, and the top is golden and bubbly.
Step 5: Let It Rest and Serve
Allow the casserole to rest for 5-10 minutes before slicing. This helps it set up perfectly and makes serving easier.
Tips to Customize Your Breakfast Casserole
- Vegetarian Version: Skip the meat and add sautéed mushrooms, spinach, or tomatoes for a veggie-packed dish.
- Spicy Kick: Add diced jalapeños or a dash of hot sauce to the egg mixture.
- Cheese Variety: Experiment with smoked gouda, feta, or Swiss cheese for different flavor profiles.
- Make-Ahead Convenience: Assemble the casserole the night before, cover tightly, and refrigerate. Bake fresh in the morning for a stress-free breakfast.
- Gluten-Free: Ensure your breakfast meat and seasonings are gluten-free, and use naturally gluten-free potatoes and cheese.
