Omelettes are a breakfast classic. They are quick and easy to make. Mushrooms are a great omelette filling, and can be easily upgraded with other things, such as cheese or onion. If you don't like eggs for breakfast, you can always have your omelette for lunch or dinner.

Ingredients^{[1]

2 teaspoons (10 grams) unsalted butter, divided

2 eggs (or 4 egg whites)
2 tablespoons (30 milliliters) water
Salt (to taste)
Pepper (to taste)

You can leave the stems on, or discard them. Be sure to scrub the mushrooms with a soft-bristled brush to remove any dirt. You don't need to peel them.

Heat 1 teaspoon (5 grams) of unsalted butter in a medium-sized frying pan over medium heat. Save the rest of the butter for frying the eggs. Wait until the butter starts to sizzle and foam.
- Alternatively, add a little avocado oil to a nonstick frying pan over medium heat and let it warm.

How much salt you use is up to your personal tastes. For extra flavor, add 1 clove of minced garlic.^{[2]

Place them into a bowl or onto a plate. Cover them with a lid, plate, or a piece of foil to keep them warm. You will be adding the mushrooms to your omelette just before serving it.

For a lighter omelette, use 4 egg whites instead.^{[5]

If you are using whole eggs (instead of whites), make sure that you break the yolks up. You won't be scrambling the eggs once you add them into the frying pan.
The butter will start to sizzle and foam. Don't add the eggs yet. Instead, wait until the foam starts to disappear.^{[7]

Tilt pan to coat the bottom with oil, then add the eggs. Once you have the eggs on the pan, continue tilting the pan around until the entire bottom is evenly covered with the egg mixture.^{[8]

Research source} If necessary, use the tip of your spatula to help spread the egg mixture across the bottom of the pan.
- For extra flavor, add 2 chopped, green shallots.^{[9]

This will happen after only a few seconds. Pulling the edges of the omelette away from the pan will allow the raw egg mixture to flow onto the hot pan and cook. ^{[10]

As it continues to cook, it will turn opaque and set. Don't "scramble" the omelette during this time, or you will get scrambled eggs instead.

Add the mushroom mixture when the omelette still has some raw egg on top. Only cover half of the omelette with the mushroom mixture; you will be folding the omelette in half. Don't worry, the omelette will continue to cook, even after you take it off the frying pan.
- If you'd like some extra flavor, add ¼ cup (25 grams) of shredded cheese. Popular choices include: cheddar, parmesan, and gruyere.^{[11]

Use your spatula to gently separate the edges of the omelette from the frying pan. Then, slip the spatula under the bare side of the omelette, and flip it over onto the mushroom side.^{[13]

If you'd like, you an garnish the omelette with some chopped chives, parsley, or grated cheese. Don't wait too long, however, or the mushrooms will turn greasy and cold.

Yes, but it will be less flavorful and won't taste quite as good as with fresh mushrooms.

Question

Can I use milk instead of water?

King Derekus of Tesco

Community Answer

I find using milk makes the omelette so much better, as you get a better consistency and a creamier flavor. If you really want that creamy flavor, try yogurt or cream.
