Denver Omelette Bake
Luna and I grew up in a house where Saturday mornings always meant a big, boisterous breakfast. My sister, Luna, usually took charge of the stovetop while I handled the heavy lifting of chopping and prep work. One of our all-time favorite orders at the local diner was the classic Western omelette.
However, as we started hosting our own brunch gatherings, we realized that flipping individual omelettes for a crowd was nearly impossible. That challenge led us to create this Denver Omelette Bake. This Denver Omelette Bake brings those iconic diner flavors to your kitchen table without the stress of standing over a hot pan all morning.

Ingredients You’ll Need
To create the best Denver Omelette Bake, you need fresh and high-quality ingredients. We recommend using large, fresh eggs and high-quality smoked ham for the most authentic flavor profile. The combination of red and green bell peppers provides a beautiful color contrast in your Denver Omelette Bake.
Make sure you grate your own cheese if possible, as pre-shredded cheese often contains anti-clumping agents that affect the melt. Every ingredient in this Denver Omelette Bake plays a vital role in creating that signature savory taste.

| Large Eggs | 12 units | Room temperature is best. |
| Whole Milk | 1 cup | You can use heavy cream for extra richness. |

Substitutions & Variations
You can easily modify this Denver Omelette Bake to match whatever you have in your pantry. If you prefer a bit of heat, substitute the green bell peppers with diced jalapeños in your Denver Omelette Bake. Instead of smoked ham, feel free to use cooked breakfast sausage or even crispy bacon bits.
For a vegetarian version of the Denver Omelette Bake, simply omit the meat and add mushrooms or spinach. You can also experiment with different cheeses in your Denver Omelette Bake, such as Monterey Jack or Pepper Jack for a spicy kick. If you need a dairy-free Denver Omelette Bake, replace the milk with unflavored almond milk and use a dairy-free cheese alternative.
Some people like to add a pinch of garlic powder or onion powder to their Denver Omelette Bake for deeper savory notes.

Step-by-Step Instructions
First, preheat your oven to 375 degrees Fahrenheit. Grease a 9×13 inch baking dish generously with butter or non-stick spray to ensure your Denver Omelette Bake does not stick. Next, place a medium skillet over medium heat and melt the tablespoon of butter.
Add the diced onions and bell peppers to the skillet. Sauté these vegetables for about 5 to 7 minutes until they soften slightly. This step is crucial for the Denver Omelette Bake because it prevents the vegetables from being too crunchy. Once the vegetables finish cooking, set them aside to cool for a few minutes.
In a large mixing bowl, crack all 12 eggs. Pour in the milk and add the salt and black pepper. Whisk the mixture vigorously until the eggs and milk are fully combined and no streaks of egg white remain.
This aeration helps make your Denver Omelette Bake incredibly light and airy. Now, stir in the diced ham and half of the shredded cheddar cheese. Add the sautéed peppers and onions to the egg mixture and stir gently to distribute the ingredients evenly.
Pour the entire mixture into your prepared baking dish. Carefully spread the ham and vegetables so they are not all clumped in one spot. Sprinkle the remaining cup of cheddar cheese over the top of the Denver Omelette Bake.
Place the dish in the center of the preheated oven. Bake the Denver Omelette Bake for 25 to 30 minutes. You will know it is done when the center is set and no longer jiggles, and the edges are slightly golden brown.
Finally, remove the Denver Omelette Bake from the oven and let it rest for at least 5 minutes before slicing. Resting allows the Denver Omelette Bake to firm up, making it much easier to serve clean squares.
Pro Tips for Success
To achieve the best results with your Denver Omelette Bake, always start with room temperature eggs. Cold eggs can sometimes lead to uneven baking in a Denver Omelette Bake. Another secret for a perfect Denver Omelette Bake is to avoid overcooking the eggs.
Eggs continue to cook even after you take them out of the oven, so pull your Denver Omelette Bake out when it just barely stops wobbling. If you want a more decadent Denver Omelette Bake, use heavy cream instead of milk. This change adds a velvety richness that mimics a high-end restaurant omelette.
Additionally, finely dicing your ham and vegetables ensures that you get a bit of everything in every single bite of your Denver Omelette Bake. Always sauté your onions and peppers before adding them to the egg mixture. This step removes excess moisture that could otherwise make your Denver Omelette Bake watery. Lastly, use a sharp knife to cut the Denver Omelette Bake to maintain those beautiful, clean layers.
