Spinach Mushroom Omelette
This easy Spinach Mushroom Omelette is a delicious keto vegetarian breakfast recipe easy to whip in 10 minutes any day of the week.
Plus, this omelette recipe has a dairy-free option!
I love French omelette for breakfast or a simple dinner and even more vegetarian omelette for a ketotarian breakfast.
What’s A Spinach Mushroom Omelette
Spinach Mushroom omelettes are a delicious version of the classic omelette.
But to make a fulfilling vegetarian omelette, you need to add two key components:
- High-fiber low-carb vegetables like spinach, kale, and broccoli.
- High-protein ingredients like cheese mushrooms, asparagus, avocado, sundried tomatoes, or kale like in my kale omelette recipe.
Are Mushrooms Low-Carb?
Absolutely yes! Mushrooms are high-protein vegetables and a great plant-based protein to add to your keto diet if you want to skip the meat.
A portion of 100 grams (3.5oz) of button mushrooms contains only 2 grams of net carbs and 3 grams of proteins.
Is Spinach Low-Carb?
Yes, spinach is a low-carb keto-friendly vegetable with only 0.4 grams of net carbs per cup of packed spinach.
Therefore, a spinach and mushroom omelette is an ideal vegetarian keto breakfast, high in protein and fiber to keep you full for hours.
How To Make A Spinach And Mushrooms Omelette
Here are my tips to make a delicious mushroom spinach omelette.
Let’s have a look at the ingredients you need:
- Large Eggs
- Mushrooms – you can use cremini mushrooms or button mushrooms.
- Baby spinach leaves or frozen spinach, you don’t need to thaw the spinach before.
- Olive oil
- Garlic cloves
- Shredded mozzarella or cheddar
First, beat the eggs in a mixing bowl and whisk vigorously with salt and pepper.
Set aside while cooking the vegetables.
Stir-Fry The Vegetables
Next, in a non-stick pan, warm and melt butter. Stir in the finely sliced mushrooms and stir fry with garlic until fragrant and roasted on all sides. Add salt and pepper if desired.
Push the cooked mushrooms on one side of the pan and add the baby spinach leaves. Stir and cook the spinach until wilted – about 1 minute.
If you are using frozen spinach, it will release some water in the pan and take longer to cook. Cook until all liquid is evaporated.
Cooking The Eggs
Set aside the cooked vegetables on a plate. Cover the plate with foil to keep the omelette filling hot and warm.
Warm some olive oil over medium heat in the same pan. If you used frozen spinach, I recommend wiping the pan with absorbent paper to remove all the water released into the pan by defrosting the spinach.
Cook the beaten egg mixture in the hot oiled pan, tilting it to spread the eggs evenly.
Lift edges to let the uncooked eggs run under.
Fill The Omelette With The Mushroom Mixture
When the sides of the omelette are cooked and crisp, add half shredded cheese on half of the omelette, then add spinach and mushrooms.
Top up with the remaining cheese.
Lift the omelette by sliding a spatula under the other side of the omelette,
Fold over the filling ingredients and keep cooking on low heat until the cheese has melted.
Serve the spinach omelette immediately, with some chopped fresh parsley, salt and pepper, and extra chili flakes for a spicy touch.
You can tweak this keto omelet recipe, adding some of the ingredients below.
For example, you can add mushrooms with onion or red pepper.
Cook the onion and mushrooms until golden brown, then cook and stir red bell pepper and spinach.
How To Make The Omelette Fluffy
To make a fluffier omelette, whisk the eggs with 2 teaspoons of heavy cream, almond milk, or even cold water.
Frequently Asked Questions
Can I Use Frozen Spinach?
Yes, you can use frozen spinach in this recipe.
You don’t have to thaw the vegetables before using them. Cook the spinach longer until all the water evaporates.
Can I Make Dairy-free Omelette?
Yes, you can skip the cheese in the recipe. For a cheesy dairy-free flavor, you can add a pinch of nutritional yeast to your beaten eggs.
Can I Freeze The Omelette?
Yes, you can freeze the cooked omelette in an airtight container.
Thaw the omelet in the fridge the day before and preferably rewarm in an oiled saucepan, with a lid on top to bring back some moisture.
I don’t recommend rewarming the omelette in the microwave. The eggs become hard, dry, and chewy.
Can I Cook Omelette In The Air Fryer?
You can air fry omelette in a small air-fryer-safe pan. The result is closer to an egg-bake than an omelette, but it creates puffy, fluffy eggs.
Air fry the beaten eggs with cooked vegetables at 350°F (180°C) for 6 to 8 minutes or until set in the center.

Unfortunately I don’t have fresh mushrooms on hand, can I use a small can instead or would it throw the flavor off completely?
I never tried canned mushrooms in omelette but I sure it will taste good if drained and stir fry in butter and garlic as mentioned in the recipe. Enjoy.
I have never in my life made an omelet correctly haha- but I found myself with too many eggs, mushrooms, and some spinach I needed to use. This was the first recipe I found, and it came out PERFECT! The fold, just the right amount of browning, even the melty cheese! I am an omelet convert! *Next time I will experiment with adding more spices integrated into the spinach or the whisked eggs but otherwise I was very satisfied! Thank you!
