This Baked Western Omelet is a classic breakfast favorite turned into an easy casserole. Loaded with ham, peppers, onions, and cheese, it bakes up fluffy and golden—perfect for a no-fuss brunch or meal prep breakfast.
Set your oven to 350°F. Lightly grease a 10-inch square baking dish with nonstick spray.
Sauté the veggies by starting with melting the butter. Add the diced onions and cook until they begin to soften, about 5 minutes. Stir in the bell peppers and cook for another 2 minutes. Remove from heat and let them cool slightly.
Whisk together the eggs, milk, salt, and black pepper until well combined.
Stir in the diced ham, shredded cheese, and the cooled sautéed vegetables.
Pour the mixture into the prepared baking dish. Bake for 45 minutes to 1 hour, or until the eggs are fully set and the omelet is cooked through.
Slice into squares and garnish with parsley, chives, green onion, avocado, or salsa if desired.
Notes
Chef Jenn’s Tips
Use a 9×13-inch baking dish instead of a square pan. This will spread out the mixture more, allowing it to cook in about 30 minutes.
Mushrooms, spinach, or tomatoes make great additions for extra flavor and texture.
Cut into squares and store in an airtight container for an easy grab-and-go breakfast throughout the week.
A pinch of cayenne or some diced jalapeños can add a little heat.
