I love when I go out to brunch and there's an omelet station. I thought it would be fun to create one at home for when my friends and family come over. Everyone can customize their omelets with their favorite ingredients. For my omelet, I love to add crabmeat, shrimp, sauteed peppers and onions, and Havarti cheese. It's so good!
Preheat the oven to its warm setting, or 200 degrees F.
Heat the oil and 1 tablespoon butter in a large skillet over medium-high heat until hot. Add the onions and cook until softened, about 5 minutes. Transfer to a bowl. Add the peppers to the skillet and cook until softened, about 3 minutes. (Add additional oil to the skillet if the vegetables are dry.) Transfer to a bowl.
Add another tablespoon butter to the skillet. Add the shrimp. Sprinkle with 1 teaspoon seafood seasoning and 1 teaspoon lemon juice. Cook until the shrimp are done and turn pink, about 3 minutes. Transfer to a bowl. Combine the crab, remaining teaspoon seafood seasoning and remaining teaspoon lemon juice in a bowl.
Set up the omelet bar: In addition to the onions, pepper and seafood, arrange the cheeses, mushrooms, diced ham, green onions and herbs in bowls on a serving platter.
Whisk together the eggs, milk, salt and pepper in a large bowl. For each omelet, melt 1 tablespoon butter in an 8-inch nonstick skillet over medium-low heat. Ladle one-quarter of the egg mixture into the skillet (enough to fill the bottom of the skillet.) Tilt the pan to spread the egg mixture evenly. Use a spatula and loosen the edges and run the uncooked yolk underneath as the omelet cooks.
Once the eggs are set, place 2 slices of cheese in a single layer to cover the egg. Sprinkle with the desired toppings on one side of the omelet. Carefully fold the omelet in half. Slide the omelet onto a serving plate and repeat with the remaining ingredients. Place the cooked omelets in the warm oven while cooking the remaining omelets, if desired.
