A Healthy Omelette recipe that tastes as fresh and delicious as it looks! A folded golden omelette, stuffed with sauteed mushrooms, spinach and melty mozzarella. An easy and healthy breakfast!

This is not a fussy breakfast. it’s the perfect balance of simple ingredients, fresh flavors and wonderful textures. I used olive oil to sauté the veggies and cook the omelet because it brings mild fruity-grassy taste to the dish and keeps saturated fat in check.
Why this Healthy Omelette is so good
- A healthier breakfast, packed with veggies, that uses olive oil to keep the saturated fats down.
- Fresh and delicious. Perfectly browned omelette, fluffy with lightly crisp edges and silky sauteed veggies.
- Easy: Just a handful of ingredients needed, all cooked in one pan.
Ingredients
- Eggs: Ideally opt for organic/free range.
- Veggies: Kale (with stems removed), portobello mushrooms and onions.
- Butter: For the omelette.
- Extra Virgin Olive Oil: To sauté the veggies.
- Cheese: I’ve gone for mozzarella, but you could use cheddar. Ideally grate you own cheese, as it melts better than pre shredded.
How to make this Healthy Omelette
Saute mushrooms and onions in a non stick pan, then set aside and saute the kale and set that aside.
In a bowl, whisk the eggs and pour into a pan with the butter, flip the omelette so it’s cooked on each side. Then add the cheese, allow it to melt, then load in the veggies.
Serve and Enjoy


Are omelettes healthy?
It all depends on what you put into your omelette, but loaded up with veggies and cooked with minimal butter, omelettes are a healthy way to kick off your day!
Along with nutrient packed kale and mushrooms, there are a lot of great reasons to eat eggs. They’re rich in vitamin E, lutein, selenium, and folate, which play important roles in brain health, vision, and fighting inflammation in the body. They also contain protein (about 6 grams per egg), which can help squash hunger and keep you feeling full for hours.
What other vegetable go well in an omelette?
Kale and mushrooms pack a nutrient rich punch and are a delicious filling. If you want to mix things up with other veggies, here are some other great fillings.
- Broccoli
- Bell Peppers
- Spinach
- Asparagus
- Green onions
- Zucchini ribbons


Omelettes for dinner!
An omelette doesn’t just have to be for breakfast, it’s hearty enough for a supper, especially with a nice side. Here are some tasty side ideas for an omelette supper:

Room Temperature Eggs
Make sure the eggs are at room temperature before cooking. Cold eggs take longer to set and this may result in overcooking.
Top Tips
- Beat the eggs well until no more flecks of white can be seen. It should be frothy and light.
- Melt the butter before adding the eggs to the pan. For a richer texture.
- Shake the pan gently to loosen any egg or filling from edge, then slide the omelet to edge of skillet.

This was absolutely delicious; however, I subbed spinach and added a little unsweetened almond milk into my eggs. I also only used a half cup of cheese.
Side note: the ingredient list says 3 eggs, but the directions say 2. I used 3 and it turned out perfect – just thought I’d let you know!
Thank you for the yummy recipe:)
