Ingredients for Hash Brown and Egg Casserole Recipe
Frozen shredded hash browns: These provide the base for the casserole, offering a crispy and hearty texture.
Cheddar cheese: Adds a rich, creamy flavor that complements the other ingredients.
Diced cooked ham: Brings a savory, meaty element to the dish.
Onion: Adds a bit of sharpness and depth of flavor.
Bell pepper: Provides a sweet and slightly tangy taste, along with a pop of color.
Eggs: Bind all the ingredients together and create a custard-like texture when baked.
Milk: Helps to create a creamy consistency in the egg mixture.
Salt: Enhances the overall flavor of the dish.
Pepper: Adds a bit of heat and depth to the flavor profile.
Technique Tip for This Recipe
When preparing this hash brown and egg casserole, ensure that the frozen shredded hash browns are fully thawed before mixing them with the other ingredients. This will help prevent excess moisture from making the casserole soggy. Additionally, for a more evenly cooked dish, sauté the diced onion and bell pepper in a little oil until they are slightly softened before adding them to the mixture. This step enhances their flavor and ensures they are perfectly tender in the final bake.

How to Store or Freeze This Dish
- Allow the hash brown and egg casserole to cool completely at room temperature before storing. This helps to prevent condensation, which can make the dish soggy.
- For short-term storage, transfer the casserole to an airtight container or cover the baking dish tightly with plastic wrap or aluminum foil. Store in the refrigerator for up to 3-4 days.
- If you plan to freeze the casserole, cut it into individual portions for easier reheating. Wrap each portion tightly in plastic wrap, then place the wrapped portions in a freezer-safe bag or container. Label with the date to keep track of freshness.
- For best results, consume frozen portions within 2-3 months. This ensures the hash browns and eggs maintain their texture and flavor.
- When ready to reheat, thaw the desired portion in the refrigerator overnight. This gradual thawing helps maintain the integrity of the cheese and vegetables.
- Preheat your oven to 350°F (175°C). Place the thawed portion in an oven-safe dish and cover with aluminum foil to prevent drying out. Heat for 20-25 minutes or until warmed through.
- Alternatively, you can reheat individual portions in the microwave. Place the portion on a microwave-safe plate, cover with a microwave-safe lid or another plate, and heat on medium power for 2-3 minutes, checking and stirring halfway through.
- For a crispier texture, consider reheating in a skillet over medium heat. Add a small amount of olive oil or butter to the pan and cook until the edges are crispy and the center is heated through.
- Always ensure the casserole reaches an internal temperature of 165°F (74°C) when reheating to ensure food safety.
