  • 8 eggs (or use 4 eggs and 6 egg whites)
  • 1 cup 2 % milk (or sub with whole milk or cream)
  • ½ teaspoon seasoned salt
  • 6 ounces (about ¾ cup) diced cooked ham
  • ½ cup shredded cheddar cheese
  • ½ cup finely chopped onion
  • ½ cup finely chopped green bell pepper
  • ½ cup finely chopped red bell pepper
  • Optional garnish: chopped fresh chives


  • Whisk together eggs, milk, and seasoned salt in a large bowl. Stir in ham, cheese, onion, and bell peppers.
  • Pour egg mixture into a greased 8-inch-square baking dish.
  • Bake at 350 degrees for 45 minutes – 1 hour, or until eggs are cooked and omelet is set.
  • Cut into squares and garnish with chives, if desired.



  • This recipe yields 4 very large slices, or 6 moderately sized slices. If you're including the omelet as a part of a larger brunch, you can cut smaller squares and even get 9 servings from the pan.
  • Lighten it up! For a lower-calorie, lower-fat meal, try omitting some of the egg yolks and adding additional egg whites in their place. Nobody will know the difference (trust me!).
  • I recommend using 2% milk, whole milk, or cream in this recipe. The fat in the milk gives the egg custard the best texture.
  • Reheat the leftover casserole by placing a slice on a microwave-safe plate and heating in the microwave for about 1 minute.
  • Want to prep ahead? You can prepare the omelet in advance, bake the dish as instructed, and cool the casserole to room temperature. Serve the omelet at room temperature (like a quiche), or reheat the omelet in a 325 degree F oven just until warmed through (about 10-15 minutes).
  • You can freeze leftovers, too! The eggs and vegetables will release some liquid when thawed, so be sure to place the slices on paper towels in the refrigerator (or on a plate) to absorb this excess moisture. Reheat a thawed omelet according to the instructions above.
  • Alternative ingredients to add to your egg omelet: The classic Western (or “Denver”) omelet usually includes bell peppers, onion, ham, and cheese, so that’s exactly what I did here. However, you can feel free to play around with the ingredients and pick all of your favorites – bacon or sausage, Swiss or American cheese, and any fresh veggies that you might have on hand.
  • Cooking for a larger group? Double the ingredients and bake the omelet in a 9 x 13-inch pan. You may need to extend the baking time by 5-10 minutes.
