Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
- Eggs
- Milk
- Salt and pepper
- Shredded cheese (cheddar, mozzarella, or your favorite blend)
- Breakfast sausage, or ham (cooked and crumbled)
- Hash browns (shredded or diced, fresh or frozen)
- Vegetables (such as bell peppers, onions, or spinach, diced)
- Butter or cooking spray (for greasing the dish)
Directions
- Preheat the Oven
Start by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray to prevent the casserole from sticking. - Cook the Meat and Vegetables
If using breakfast sausage or ham, cook it thoroughly until it’s crispy and browned. If you prefer veggies in your casserole, sauté them until they’re tender and fragrant, which will bring out their natural flavors. - Layer the Ingredients
Spread the hash browns evenly at the bottom of the prepared baking dish. Then, layer the cooked meat and sautéed vegetables on top. Sprinkle half of the shredded cheese over the mixture to add a cheesy layer of goodness. - Mix the Egg Mixture
In a separate bowl, whisk together the eggs, milk, salt, and pepper. Pour this mixture evenly over the layered ingredients in the casserole dish, ensuring every bit of the hash browns and toppings is covered. - Top with Cheese
Sprinkle the remaining shredded cheese generously on top. This will melt into a gooey, golden topping as the casserole bakes. - Bake the Casserole
Place the casserole in the oven and bake, uncovered, for 35-40 minutes. The casserole is done when the eggs are fully set, and the top is golden and bubbly. - Cool and Serve
Allow the casserole to cool for a few minutes before slicing and serving. This will help the layers set and make it easier to serve.

FAQs
Can I use fresh potatoes instead of hash browns?
Yes! Shred or dice fresh potatoes, but make sure to remove any excess moisture by squeezing them out before using them in the casserole. This will help prevent the dish from becoming too watery.
Can I prepare this casserole the night before?
Absolutely! You can assemble the casserole the night before and store it in the refrigerator. In the morning, simply bake it fresh for a warm, comforting breakfast.
How do I prevent the casserole from being watery?
The key is to make sure any frozen ingredients, like hash browns or vegetables, are completely thawed and patted dry before assembling the casserole. This helps remove excess moisture, ensuring a perfectly baked dish.
Can I make this dairy-free?
Yes, you can easily make this casserole dairy-free by substituting regular milk with a non-dairy alternative like almond milk, soy milk, or oat milk. You can also use dairy-free cheese to keep it entirely dairy-free.
How do I know when the casserole is done?
The casserole is done when the top is golden brown, and a knife or toothpick inserted into the center comes out clean.
Can I add bread instead of hash browns?
Yes! You can use cubed bread, like French bread or sourdough, in place of the hash browns. This will give the casserole a different texture and flavor while still being delicious.
Can I double the recipe?
Yes, you can easily double this recipe. Just use a larger baking dish or prepare two separate casseroles to feed a larger crowd.
What toppings pair well with this dish?
Some great topping options for this casserole include sour cream, salsa, avocado, or fresh herbs like cilantro or parsley for a burst of color and freshness.
Can I use egg whites instead of whole eggs?
Yes, you can substitute whole eggs with egg whites or a combination of both for a lighter version of this casserole.

Of course! Adding cheese both inside the casserole layers and on top ensures that every bite is bursting with cheesy goodness.
