Denver Omelet Ingredients

• Egg and Egg Whites: A combination of 4 whole eggs and 6 egg whites (I don’t recommend substituting for whole eggs) adds fluff and lean protein without excess calories from the yolks. For extra protein, you can replace the whole eggs with more egg whites (8 additional whites).
• Greek Yogurt: Adds lean protein and creaminess to the casserole, making it extra fluffy. Cottage cheese is a good alternative. Dairy-free options aren’t recommended for consistency purposes, except this high-protein dairy-free yogurt option.
• Ham: Provides smoky flavor and meaty texture. You can swap it with Canadian bacon, cooked turkey bacon, or tempeh for a vegetarian version.
• Veggies: Green and red bell peppers, plus onions, provide color and nutrition to the wholesome oven omelette.
• Cheddar Cheese: Adds a melty element and flavor. I used low-fat shredded cheese, but you can use any cheese you like or opt for dairy-free cheese or nutritional yeast.

Variations & Dietary Modifications

• Protein Combo: Boost the protein in this recipe for Denver omelet and the flavor by adding ground turkey or crumbled sausage for an even heartier oven baked omelette.
• Make it Spicy: Add diced jalapeños, a dash of hot sauce, or a sprinkle of red pepper flakes if you like your breakfast with a spicy kick.
• Vegetarian Version: Skip the ham and cheese, and load up on non-starchy vegetables like zucchini, summer squash, spinach, mushrooms, or asparagus for a filling, vegetarian option.

How To Make An Omelet Casserole

Ready to whip up a delicious baked Denver omelet casserole in just 3 steps? Simply preheat your oven to 400°F, grab your greased 9-inch by 13-inch casserole dish, gather your prepped ingredients, and let’s get whisking!

Step 1: Whisk and Mix. In a large mixing bowl, whisk together the eggs, egg whites, and Greek yogurt until smooth and fluffy. Then, stir in the ham, bell peppers, onion, and seasoning until well combined.

Step 2: Transfer and Top. Pour the egg mixture into your greased dish and top with the shredded cheese.

Step 3: Bake, Rest and Serve. Bake at 400°F for 25-28 minutes, or until golden brown with crispy edges. Let the dish rest for 15 minutes before slicing and serving!

Expert Tips

• Cook Veggies First: If you have the time, sauté the veggies briefly in a skillet before adding them to the egg mixture. This will help release excess moisture and enhance the flavors.
• Whisk Well: The longer you whisk the eggs and egg whites, the more air you incorporate, which results in a fluffier texture and better overall consistency in this oven omelette recipe.
• Storing: Store any leftovers in an airtight container in the refrigerator for up to 4 days or freeze for up to 3 months.
• Reheating: To reheat, thaw the casserole in the refrigerator overnight, or heat directly in the oven. For individual slices, microwave for 30-second intervals until heated through, or place slices on a sheet pan at 350°F for 10 minutes, or until warmed throughout.
