Step-by-Step Instructions

This sheet pan omelette recipe is simple and forgiving. Follow along with the process photos and you will see how easy it is to bake an omelette on a sheet pan.

Step 1: Turn the broiler on high and move the oven rack at least 12 inches from the element. Spray a small sheet pan with nonstick spray and scatter the peppers, onions, and ham evenly across the pan. Seasonal with a little bit of the salt and pepper. Broil until lightly charred.

Step 2: While the vegetables broil, shred the cheese and whisk the eggs, cream, salt, and pepper together until fully combined.

Step 3: Remove the pan from the oven and lower the temperature to 375°F. Slowly pour the egg mixture over the vegetables and ham, using the back of a spoon to avoid disturbing the ingredients.

Step 4: Sprinkle the shredded cheddar evenly over the top and bake until the center is just set, about 18 to 20 minutes.

Serve: Let the omelette cool slightly, then slice into portions. Serve as is or build it into a breakfast sandwich, pair with breakfast potatoes, or serve alongside a simple salad.

• Store leftovers in the refrigerator for up to 4 days.
• Reheat gently in the microwave in 20 second bursts to avoid drying out.

Serving Suggestion

Sometimes all I'm craving is one of these simple sheet pan omelettes with a little fresh berry salad in a little dish on the side, but sometimes I wanna make an entire loaf of sandwich bread, toast a couple of slices, and slide a piece of this omelette in between with some crispy bacon and melty cheese. I am a woman of many moods.
