How to Make California Sheet Pan Omelette

Preheat: Begin by preheating your oven to 350°F. While it’s heating up, line the bottom of a rimmed sheet pan with parchment paper for easy cleanup, then lightly grease it with oil or cooking spray.
Whisk Together: In a large mixing bowl, whisk together 12 large eggs, ½ cup half and half, 1 teaspoon kosher salt, and ½ teaspoon black pepper. You want the mixture to be a pale yellow, indicating it’s well combined.
Pour and Bake: Pour the egg mixture into the prepared sheet pan, making sure it spreads evenly. Sprinkle 2 cups shredded cheddar cheese and 4 ounces of sliced fresh mushrooms over the top. Place the pan in the preheated oven and bake for about 25 minutes, or until the eggs are completely set and the edges are lightly golden.
Slice and Serve: Once your omelette is perfectly cooked, remove it from the oven and allow it to cool slightly. Use a sharp knife or a pizza cutter to slice the omelette into 8 equal servings. Serve warm, topped with slices of avocado and diced tomato for added freshness and flavor.
Storing & Reheating
To store leftovers of your California Sheet Pan Omelette, keep them at room temperature for a maximum of 2 hours after cooking. If needed, place them in an airtight container and refrigerate for up to 3 days. You can also freeze this omelette for up to 3 months—just cut it into portions and wrap them well. For reheating, pop it in the oven at 350°F for about 10-15 minutes or until warmed through, though the texture may vary slightly after freezing. A quick blast in the microwave will also do if you’re in a hurry.
Chef’s Helpful Tips
- Avoid overcooking the omelette; keep an eye on it while it bakes to ensure it stays fluffy and moist.
- Use room temperature eggs for a softer, fluffier omelette.
- Feel free to get creative with your veggies and proteins—spinach, bell peppers, or sausage also work beautifully.
- To enhance the flavor, try adding herbs like chives or parsley before baking.
- Make your sheet pan omelette ahead of time for easy brunch prep; just reheat before serving.
