Ingredients
• 1 cup whole milk
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1 cup shredded cheddar cheese
• 1 cup diced bell peppers (a mix of red, green, and yellow for color)
• 1 cup diced onions
• 2 tablespoons unsalted butter, melted
The key ingredients that make this Denver omelette casserole truly special are the eggs and the combination of bell peppers and onions. The eggs provide a rich, custard-like texture that’s the hallmark of a classic omelette, while the peppers and onions add a flavor-packed punch that perfectly complements the cheese and eggs.
For the eggs, be sure to use large, fresh eggs for the best results. The whole milk helps create a luxuriously creamy texture, and the salt and pepper enhance the overall flavor. As for the vegetables, feel free to adjust the ratios or use your favorite bell pepper and onion varieties to suit your taste preferences.
Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C). This ensures the casserole bakes evenly and develops a beautiful golden-brown top.
- Prepare the Egg Mixture: In a large mixing bowl, whisk together the eggs, milk, salt, and black pepper until well combined. The milk helps create a light and fluffy texture, while the seasoning enhances the overall flavor.
- Add the Fillings: Stir in the shredded cheddar cheese, diced bell peppers, and diced onions. Gently fold the ingredients together until they are evenly distributed throughout the egg mixture.
- Grease the Baking Dish: Lightly grease a 9×13-inch baking dish with the melted butter. This will prevent the casserole from sticking to the sides and ensure easy slicing.
- Pour and Bake: Pour the egg mixture into the prepared baking dish, making sure to distribute the fillings evenly. Bake for 35-40 minutes, or until the center is set and the top is golden brown and slightly puffed.
- Let it Rest: Remove the casserole from the oven and let it rest for 5-10 minutes before slicing. This allows the eggs to finish cooking and the casserole to firm up, making it easier to serve.

How to Customize This Recipe ?
• To Make it Vegetarian: To make this Denver omelette casserole vegetarian, simply omit the bell peppers and onions, and substitute them with your favorite vegetable fillings, such as sautéed mushrooms, spinach, or diced tomatoes.
• To Add a Spicy Kick: For a little extra heat, try adding a diced jalapeño or a sprinkle of cayenne pepper to the egg mixture. You can also serve the casserole with a side of your favorite hot sauce for those who want to amp up the spice level.
Elevate Your Meal with These Serving Tips
• Garnish Suggestions: Garnish the top of the casserole with a sprinkle of chopped fresh chives or parsley, a dollop of sour cream, and a few slices of avocado for a visually stunning and flavor-packed presentation.
• Beverage Pairing: This dish pairs wonderfully with a crisp, chilled white wine or a refreshing mimosa for a delightful brunch experience. For a non-alcoholic option, a glass of freshly squeezed orange juice or a creamy hot chocolate would also be a perfect complement.
Troubleshooting Common Recipe Issues
• Mistake 2 – Using Cold Ingredients: For the best texture and cooking results, make sure all the ingredients are at room temperature before starting. Cold eggs and milk can cause the casserole to bake unevenly and result in a dense, rubbery texture.
• Mistake 3 – Not Preheating the Oven: Properly preheating the oven is crucial for ensuring the casserole rises and bakes evenly. If the oven is not hot enough, the casserole may not set properly and could end up underbaked or soggy.
Smart Storage for Maximum Flavor
• Freezing: This casserole freezes exceptionally well. To freeze, allow the casserole to cool completely, then cut it into individual portions and wrap them tightly in aluminum foil or plastic wrap. Freeze for up to 3 months.
• Reheating: To reheat, simply place the frozen or refrigerated casserole in a preheated 350°F (175°C) oven for 10-15 minutes, or until heated through. Alternatively, you can microwave individual slices for 1-2 minutes, or until hot.
FAQs

Can I use a different type of cheese?
Yes, you can definitely experiment with different cheese varieties. While cheddar cheese is the classic choice for a Denver omelette, you could also try using Monterey Jack, pepper Jack, or a blend of cheeses to suit your taste preferences.
How can I make this recipe dairy-free?
To make this Denver omelette casserole dairy-free, simply substitute the whole milk with unsweetened almond milk or oat milk, and use a dairy-free shredded cheese or a nut-based cheese alternative. Just be sure to adjust the seasoning as needed to compensate for the changes in flavor and texture.

Absolutely! For a heartier, protein-packed version, you can easily add cooked and crumbled sausage, diced ham, or crispy bacon to the egg mixture. Just be sure to adjust the overall seasoning and fillings to balance the added meat.
