Step‑by‑Step Instructions for Denver Omelet Egg Bake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven is warming up, take a moment to lightly grease a 9×13-inch baking dish with cooking spray or butter. This will ensure your Denver Omelet Egg Bake doesn’t stick, allowing for easy serving and clean-up when it’s time to enjoy your delicious breakfast.
Step 2: Whisk the Egg Mixture
In a large mixing bowl, crack open a dozen large eggs and whisk them together with 1 cup of milk, salt, and pepper. Aim for a light and airy texture, beating the eggs until they’re pale yellow. This step is crucial for creating a fluffy base for your omelet casserole.
Step 3: Add the Fillings
Next, fold in your diced ham, chopped red and green bell peppers, and finely chopped onion into the egg mixture. Stir in 1 to 2 cups of shredded cheddar cheese, ensuring everything is well-coated. These colorful ingredients will infuse your Denver Omelet Egg Bake with savory flavors, making each bite a delight.
Step 4: Pour and Bake
Carefully pour the egg and filling mixture into the prepared baking dish, spreading it evenly with a spatula. Place the baking dish in the preheated oven and bake for about 45 minutes. Keep an eye on it; your omelet should puff up and turn golden brown on top, which is a sign that it’s perfectly cooked.
Step 5: Cool and Slice
Once the baking time is up, remove the Denver Omelet Egg Bake from the oven and let it cool for about 10-15 minutes. This slight cooling period helps the dish set further and makes slicing easier. You’ll want the top to retain its beautiful golden hue while the inside remains fluffy.
Step 6: Serve and Enjoy
After cooling, cut the Denver Omelet Egg Bake into squares and serve warm. Consider garnishing each portion with fresh herbs or a dollop of sour cream for added flavor. This delightful breakfast casserole is perfect for any meal, making your family gatherings warm and memorable.
