Ingredients You’ll Need
The beauty of this Easy Denver Omelet Hash Brown Casserole Recipe is how it transforms simple, everyday ingredients into a vibrant, satisfying meal. Each component plays a special role, from the creamy eggs to the crisp hash browns and the colorful mix of veggies and ham.
- Frozen shredded hash browns (26 oz): Using thawed hash browns gives your casserole a soft, hearty base that soaks up all the savory flavors.
- Olive oil or butter (1 tablespoon): A touch of fat helps sauté the ham and veggies until they’re sweet and golden.
- Diced ham (1 cup): Ham adds smoky, salty flavor and lots of protein; feel free to use leftovers or deli ham.
- Diced green bell pepper (1/2 cup): Green peppers bring a subtle bitterness and beautiful color.
- Diced red bell pepper (1/2 cup): Red peppers provide a sweet pop that balances the savory notes.
- Diced onion (1/2 cup): Onion caramelizes as it cooks, adding depth and a hint of sweetness.
- Large eggs (8): Eggs are the heart of the casserole, binding everything together and making it fluffy.
- Milk (1 cup): Milk helps create a tender, custardy texture in the baked eggs.
- Shredded cheddar cheese (1 1/2 cups): Cheddar melts into gooey, tangy layers that make every bite irresistible.
- Salt (1/2 teaspoon): A little salt brings out all the other flavors in the casserole.
- Black pepper (1/4 teaspoon): Pepper adds just the right amount of gentle heat and earthiness.
- Garlic powder (1/4 teaspoon): Garlic powder gives the eggs a savory, aromatic boost with zero fuss.
How to Make Easy Denver Omelet Hash Brown Casserole Recipe
Step 1: Prep the Oven and Baking Dish
Start by preheating your oven to 375°F (190°C). Give your 9×13-inch baking dish a light greasing with oil, butter, or nonstick spray. This step ensures your Easy Denver Omelet Hash Brown Casserole Recipe comes out cleanly and has those coveted golden edges.
Step 2: Sauté the Ham and Vegetables
Heat the olive oil or butter in a large skillet over medium heat. Add your diced ham, green and red bell peppers, and onion. Sauté everything together for about 5 to 7 minutes, stirring occasionally, until the veggies are tender and just starting to caramelize. Not only does this deepen the flavors, but it also brings out the natural sweetness in the veggies and gives the ham a deliciously crisp edge.
Step 3: Assemble the Casserole Layers
Spread the thawed hash browns evenly across the bottom of your prepared baking dish. They form the sturdy, comforting base. Next, layer on your warm ham and veggie mixture, making sure every bite is loaded with color and flavor.
Step 4: Whisk the Eggs and Cheese
In a large bowl, whisk together the eggs, milk, salt, black pepper, and garlic powder until smooth. Stir in 1 cup of the shredded cheddar cheese to give the casserole a rich, cheesy interior. This custard mixture will puff up beautifully as it bakes, enveloping the veggies and ham.
Step 5: Pour, Top, and Bake
Pour the egg mixture evenly over the hash browns and veggie-ham layer, gently tilting the dish if needed to cover every nook. Sprinkle the remaining 1/2 cup of cheddar cheese over the top for that signature bubbly, golden finish. Slide the dish into your oven and bake uncovered for 40 to 45 minutes, or until the center is set and the top is irresistibly browned. Let it rest for 5 to 10 minutes before you slice and serve—this helps the casserole hold its shape and makes serving a breeze.
How to Serve Easy Denver Omelet Hash Brown Casserole Recipe
Garnishes
Brighten up your Easy Denver Omelet Hash Brown Casserole Recipe with a sprinkle of fresh herbs like chopped chives or parsley just before serving. A dollop of sour cream or a dash of hot sauce adds extra flair and flavor. For a little crunch, try a handful of crispy fried onions or even some sliced green onions on top.
Side Dishes
Pair your casserole with some simple sides to create a balanced brunch spread. Fresh fruit salad brings a sweet contrast, while a mixed greens salad with a tangy vinaigrette keeps things light. Toasted English muffins or warm, flaky biscuits are fantastic for soaking up every last bit of eggy goodness.
Creative Ways to Present
If you want to take your presentation up a notch, try baking the casserole in individual ramekins for personalized servings—perfect for brunch parties. Or, cut the casserole into small squares and serve as finger food at a breakfast buffet. You can also wrap slices in tortillas for a quick breakfast burrito twist!
Make Ahead and Storage
Storing Leftovers
Leftover Easy Denver Omelet Hash Brown Casserole Recipe keeps beautifully in the fridge. Cover the casserole dish tightly with foil or transfer slices to an airtight container. Refrigerate for up to 4 days, and you’ll have a ready-made breakfast that reheats in minutes.
Freezing
This casserole is wonderfully freezer-friendly. Once cooled, wrap individual portions or the whole dish tightly in plastic wrap and foil. Freeze for up to 2 months. When you’re ready, just thaw overnight in the fridge and reheat as needed—breakfast meal prep doesn’t get easier!
Reheating
To reheat, simply pop a slice in the microwave for about a minute, or warm larger portions in a 350°F oven until heated through (about 15 minutes). If you’re reheating from frozen, allow it to thaw first for the best texture. The casserole stays moist and cheesy, making leftovers just as yummy as the first day.
FAQs
Can I make the Easy Denver Omelet Hash Brown Casserole Recipe the night before?
Absolutely! Prepare the casserole as directed, cover, and refrigerate overnight. In the morning, let it sit at room temperature while the oven preheats, then bake as usual for a stress-free, delicious breakfast.
Can I use fresh potatoes instead of frozen hash browns?
Yes, you can use freshly shredded potatoes. Just be sure to squeeze out excess moisture with a clean kitchen towel before layering them in the dish—this helps avoid a soggy casserole and gives you that perfect, crisp texture.
Is there a dairy-free option for this casserole?
Definitely! Swap the milk for your favorite unsweetened non-dairy milk (like almond or oat), and use a plant-based cheese alternative. The Easy Denver Omelet Hash Brown Casserole Recipe is very adaptable and still tastes fantastic with these swaps.
What other proteins can I use besides ham?
Feel free to substitute cooked bacon, turkey sausage, or even leftover roast chicken for the ham. Each protein brings its own delicious twist, making this casserole a great way to use what you have on hand.
Can I add extra veggies or swap in others?
Absolutely! Mushrooms, spinach, or even diced tomatoes can be stirred into the sautéed veggies. Just be sure to cook out any excess moisture before adding them to the casserole, so everything bakes up perfectly.
