A nonstick skillet is essential if you want to make an egg-cellent omelet!
In 10-inch nonstick skillet, melt butter over medium heat until hot, swirling to evenly coat skillet, about 1 minute.
Add eggs to skillet and stir gently with rubber spatula until eggs just begin to set, about 10 seconds.
Use spatula to gently pull and lift cooked eggs into center of skillet. Tilt and swirl skillet so uncooked eggs run to cleared edges of skillet. Cook until egg on top is mostly set but still moist, 1 to 2 minutes.
In addition to substituting your favorite cheese for the cheddar, you can customize your omelet with add-ins (use one or make your own combo): quartered cherry tomatoes, diced ham, chopped baby spinach, chopped scallions, minced chives, or minced parsley. Sprinkle 2 tablespoons of your favorite add-in ingredients over half of omelet after you sprinkle with cheese.
A nicely cooked omelet is a thing of beauty. Some well-known French restaurant chefs like to evaluate potential new kitchen hires by asking them to make an omelet. It seems so simple, but it’s not easy. Practice often and you will get the hang of it! This recipe is best done with adult supervision.
