Tips on Making Tomato and Mushroom Omelette

Make breakfast or lunch fun with this delicious tomato mushroom omelette made with simple ingredients. What makes omelette recipes extra wonderful to make is that you can include other kinds of ingredients for something even tastier. You can mix and match some of your favorite mushrooms or cheese. Our helpful tips below will let you know what are the best things to put in an omelette. 

  • Mix up your choice of mushrooms. Instead of adding one type of mushroom, why not try adding in other mushrooms like button mushrooms, cremini mushrooms, or baby portabella mushrooms. You can also try a chestnut mushroom variation which has a slightly deeper flavor and is a bit denser than cremini. These are just some of the mushroom types that you can use to enhance the flavor of your omelette. 
  • Add in a bit of butter. If you prefer a subtle buttery taste to your tomato mushroom omelette, then we recommend adding ½ teaspoon of butter. You can also use butter as a substitute for the cooking spray or olive oil when cooking the omelette.
  • Try adding in cheese. Classic omelette dishes add cheese to enhance the flavor of the egg dish. If you want a slightly salty taste to the egg, then mix in some grated or shredded cheese like provolone, fontina cheese, cheddar cheese, or even a low-fat cream cheese. Just remember to choose a cheese that melts quickly so you can enjoy the taste and texture more.
  • Garnish with fresh herbs. Finish off the dish with some additional herbs like fresh chives, basil, or a chopped flat leaf parsley. This will not only give the dish herby flavor, but will also make the tomato mushroom omelette look extra appetizing.

Frequently Asked Questions

What is the difference between a French omelette and an American omelette?

A French omelette is different from its American counterpart. The classic French omelette is only made using eggs and butter. It’s only soft, fluffy, and moist in texture which makes it really delicious and tender to eat. On the other hand, an American omelette always has fillings. It’s also cooked folded in half while the French version is rolled up into an oval. With the American omelette, you can make a lot of variations like this tasty tomato mushroom omelette recipe. You’re free to customize your omelette however you like to match your taste.

Do you add milk to omelette?

No. Most of the time, only water is added to omelette recipes. Never add milk to the egg mixture as it can make the omelette watery. The milk also doesn’t blend well with the eggs. Water is usually added to make omelettes fluffy. As soon as water hits the pan, the steam rises through the omelette and helps the egg fluff up.
