Spinach Mushroom and Feta Omelet on a white plate

Spinach Mushroom Omelette

If you’re looking for an easy, savory breakfast that will keep you full, this omelette is perfect. A savory breakfast omelette is a classic dish that’s not only versatile, but easy to make.

This omelette is packed full of eggs, mushrooms, spinach, and feta cheese. The technique of making an omelette can feel overwhelming, but with a few basic ingredients, you’ll have a filling breakfast the family will love.

Even though the omelette is vegetarian, the mushrooms pack a meaty punch that will not have you missing the usual ham or sausage. You can also top it with extras too. Some great toppings include onions, garlic, pico de gallo, sriracha, and roasted green chile for a spicy kick.

Ingredients for Spinach and Mushroom Omelette with Feta

  • Baby Bella Mushrooms (sliced) – Baby bella mushrooms are meatier than other variaties, but white and button also work well in this recipe.
  • Baby Spinach – Kale can be substituted for the baby spinach, but will require a little extra cooking time.
  • Whole Egg
  • Egg White – You can use two whole eggs instead of using egg whites. The use of egg whites helps add a fluffier texture to the omelet.
  • Reduced Fat Feta Cheese – Full fat feta works as well or you could substitute gorgonzola or even blue cheese.
  • Salt & Pepper

How many eggs go into an Omelette?

2 eggs (or 1 whole egg and 1 egg white) are used when making an omelette for one.

How to Make Spinach Feta Omelette

  1. Start by spraying a skillet with nonstick spray.

  2. Add in the sliced mushrooms and saute, stirring occasionally until the mushrooms begin to soften.

  3. Once the mushrooms have softened, add in the baby spinach. Saute until wilted, adding in the salt and pepper to taste.

  4. Once the mushrooms have cooked through and spinach is wilted, remove them from the skillet and set aside.

  5. To a small bowl, add the egg and egg white whisking until light and fluffy.

  6. Return the skillet to the heat and spray again with nonstick spray.

  7. Pour the eggs into the skillet. Be sure not to stir or break up the eggs.

  8. Once they begin to firm (about 1-2 minutes), run a rubber spatula around the edges and then flip it completely over.

  9. Add the spinach, mushrooms, and feta to half of the omelet. Fold the other side over the mix.

  10. Remove from the stove and serve with extra feta on top.

    Looks deeeeeeeeelish. Lately I’ve been having intense cravings for mushrooms (is that weird?) and I’ve decided that they won’t go away until I give in so I’ve been looking up tons of tasty recipes that I can incorporate mushrooms into. This omelette looks like a perfect candidate and only 145 calories?? That’s what I’m talkin’ about.
