Breakfast casseroles make an easy option when you need to feed a group or prep ahead for the week. These recipes use eggs and hash browns as the main ingredients and add simple mix ins like vegetables or cheese. You can adjust them based on what you have in the fridge. Here are 12 ideas that come together with basic steps and store well for leftovers. They work for regular mornings without much extra effort.
Helpful Tips Before You Start
These tips will help your egg and hash brown casseroles cook evenly with good texture and flavor.
Brown the Hash Browns First
Frozen hash browns hold a lot of water. Cook them in a skillet until golden before mixing them in to prevent a soggy base.
Whisk Eggs Thoroughly
Beat the eggs with milk or cream until smooth. This step creates a custard-like layer that sets evenly around the potatoes.
Add Cheese in Layers
Mix some cheese into the filling and sprinkle more on top. The middle layer melts into the eggs while the top forms a golden crust.
Rest Before Serving
Let the baked casserole sit for 10 minutes after it comes out of the oven. This helps the slices hold together when you cut them.
Assemble Ahead if Needed
You can build the dish the night before and cover it in the fridge. Add 10 to 15 minutes to the bake time if it goes in cold.

Ingredients

- Heat the olive oil in a large skillet over medium heat. Add the frozen hash browns and cook for 6 to 8 minutes, stirring occasionally, until they begin to turn golden.
- Stir the spinach and sun-dried tomatoes into the skillet. Cook for 2 minutes until the spinach wilts, then remove the pan from the heat.
- In a mixing bowl, whisk the eggs, milk, salt, and black pepper until smooth. Stir in half of the feta cheese.
