The magic of this Easy Denver Omelet Hash Brown Casserole Recipe lies in its classic, straightforward ingredients that each bring something essential to the table.

- 6 large eggs: The perfect base for the casserole, binding all ingredients with richness and fluffiness.
- 1 cup whole milk: Adds creaminess to the eggs for a tender, custard-like consistency.
- 1/2 teaspoon salt: Enhances all the flavors without overpowering the dish.
- 1/4 teaspoon black pepper: Gives a subtle heat and balance to the savory notes.
- 2 cups frozen hash browns (thawed): Provides a crispy yet soft texture that forms the hearty base.
- 1 cup diced cooked ham: Adds savory, smoky flavor and protein for substance.
- 1/2 cup diced green bell pepper: Offers a fresh, slightly bitter crunch and vibrant color.
- 1/2 cup diced red bell pepper: Brings sweetness and brightness to the mix.
- 1/2 cup diced onion: Energetic aroma and a touch of sweetness when baked.
- 1 1/2 cups shredded cheddar cheese: Melts beautifully to add gooey, sharp flavor and a golden topping.
- Nonstick cooking spray or butter: For greasing the baking dish to ensure easy serving and perfect crust.
How to Make Easy Denver Omelet Hash Brown Casserole Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 375°F (190°C). This steady temperature ensures your casserole cooks evenly and develops that irresistible golden crust on top. Lightly grease a 9×9-inch or 8×11-inch baking dish with nonstick cooking spray or a bit of butter, which keeps the casserole from sticking and helps achieve a perfect slice.
Step 2: Whisk the Egg Mixture
In a large mixing bowl, whisk together the 6 eggs, 1 cup whole milk, 1/2 teaspoon salt, and 1/4 teaspoon black pepper until the blend is smooth and cohesive. This egg mixture is what holds everything together, creating a rich and fluffy texture that mimics the comforting softness of a Denver omelet but in casserole form.
Step 3: Add the Main Ingredients
Now, fold in 2 cups of thawed hash browns, 1 cup diced cooked ham, 1/2 cup each of diced green and red bell peppers, 1/2 cup diced onion, and 1 cup of shredded cheddar cheese. Make sure the ingredients are evenly mixed so that every bite delivers the perfect balance of savory ham, fresh veggies, and melty cheese.
Step 4: Assemble the Casserole
Pour the mixture into your prepared baking dish, using a spatula to spread it out evenly. Sprinkle the remaining 1/2 cup of shredded cheddar cheese on top to create a delightful melted topping that browns beautifully in the oven, sealing in the flavors and adding an irresistible texture.
Step 5: Bake to Perfection
Bake the casserole for 40 to 45 minutes, until the center is fully set and the top is a gorgeous golden brown. Let it cool for 5 to 10 minutes before slicing into it; this rest period helps the flavors settle, making serving easier and bites neater.
How to Serve Easy Denver Omelet Hash Brown Casserole Recipe
Garnishes
To elevate your presentation and add an extra layer of flavor, consider garnishing with fresh chopped chives or parsley. A dollop of sour cream or a few slices of ripe avocado also create a lovely contrast, adding creaminess and freshness that complements the casserole’s richness.
Side Dishes
This casserole shines on its own but pairs wonderfully with a crisp mixed green salad to balance the indulgence. Fresh fruit like melon or berries provides a refreshing, juicy counterpoint that wakes up your palate. For heartier brunches, some toasted crusty bread or buttery croissants make an excellent accompaniment.
Creative Ways to Present
If you want to impress your guests or switch things up, serve this casserole in individual ramekins for a personalized touch. You could also layer it with additional veggies or swap ham for breakfast sausage or bacon for variety. Add some hot sauce or salsa on the side to spice things up and customize each serving.
Make Ahead and Storage
Storing Leftovers
After enjoying your first serving, store any leftovers in an airtight container in the refrigerator for up to 3 days. The casserole holds its flavor and texture well, making for easy next-day breakfasts that feel just as special.
Freezing
This Easy Denver Omelet Hash Brown Casserole Recipe freezes beautifully. Simply wrap cooled portions tightly in plastic wrap and foil or place in freezer-safe containers. It can last up to 2 months in the freezer, ready for quick reheating when you need a comforting meal on short notice.
Reheating
Reheat slices in the microwave for about 1 to 2 minutes or until warmed through. For a crispier finish, pop it in a preheated oven at 350°F (175°C) for 10–15 minutes. Both methods bring back that casserole charm, making leftovers just as dreamy as fresh.
FAQs
Can I use fresh potatoes instead of frozen hash browns?
Absolutely! If you prefer fresh potatoes, grate them and rinse well to remove excess starch, then pat dry before using. Keep in mind fresh potatoes might need a bit more cook time to fully soften in the casserole.
Is it possible to make this casserole vegetarian?
Yes, you can easily omit the ham and add extra bell peppers, mushrooms, or cooked spinach instead. Using a vegetarian cheese or skipping the meat altogether still creates a satisfying breakfast dish.
Can I prepare this casserole the night before?
Definitely. Prepare the casserole as directed, cover, and refrigerate overnight. When ready to bake, add an extra 5 to 10 minutes to the cooking time to ensure it’s thoroughly heated through.
What type of cheese works best in this recipe?
Cheddar is classic for this recipe because of its sharp flavor and good melting quality. However, feel free to experiment with Monterey Jack, Colby, or even a blend for a slightly different taste profile.
Can I add other spices or herbs?
Sure! While the recipe keeps things simple and perfect as is, adding a pinch of smoked paprika, garlic powder, or fresh herbs like thyme or oregano can add a lovely depth that personalizes your casserole.
