🍳 STEP-BY-STEP how to make Oven Baked Denver Omelette

Step 1 — Preheat & Prep Pan

1. Preheat oven to 375°F (190°C).
2. Lightly grease a 9×13-inch baking dish with olive oil or butter.
   • Pro Tip: Grease thoroughly so the omelette releases easily after baking.

Step 2 — Prep Vegetables & Ham

1. Dice bell peppers and onions into small, even pieces for uniform cooking.
2. Dice ham into ½-inch cubes.
3. Optional: lightly sauté vegetables in 1 teaspoon olive oil for 2–3 minutes to soften and reduce excess moisture.

Step 3 — Whisk Eggs

1. In a medium bowl, whisk together 6 eggs, ½ cup milk, salt, and pepper until frothy and well combined.
2. Tip: Whisking incorporates air for a fluffier omelette.

Step 4 — Combine Ingredients

1. In the prepared baking dish, layer vegetables and ham evenly.
2. Pour the egg mixture over the top.
3. Sprinkle shredded cheese evenly over the entire dish.
   • Pro Tip: Cheese on top creates a golden, bubbly crust during baking.

Step 5 — Bake

1. Bake at 375°F for 20–25 minutes, or until eggs are set in the center.
2. Test for doneness: Insert a knife into the center — it should come out clean.
3. Optional: Broil for 1–2 minutes to brown the cheese lightly.

Step 6 — Serve

1. Let the omelette rest for 3–5 minutes before slicing.
2. Garnish with fresh parsley or a dash of hot sauce/salsa.
3. Slice into squares or rectangles for easy serving.
