Chicken fajita omelette is a flavorful way to enjoy protein and vegetables for breakfast
As much as I enjoy sweet recipes, I love a hearty breakfast that’s full of veggies and protein. This chicken fajita omelette recipe is an easy breakfast, and I love it because:
- It’s full
- Perfect for using up leftover chicken
- Full of vegetables
- Quick to make
- Delicious with guacamole and sour cream
Using leftover chicken, this chicken fajita omelette recipe is not only quick, but also delicious and filling.


This fajita omelette recipe is perfect for using up leftover chicken
This fajita chicken omelette is a great way to use up leftover chicken from dinner the night before. In fact, when I serve chicken for dinner, I often put some aside to use for breakfast the next morning.
It’s great if you use leftover rotisserie chicken, but almost any rotisserie chicken will do
Rotisserie chicken is very cheap and easy to use in this recipe. But almost any grilled chicken will work. To make this omelette, just remove the meat from the bone and remove the skin.
If you’re in a pinch, you can even use grilled chicken breasts from the supermarket. You often find it whole like deli meat, but cut it into thick slices or chunks instead of thin slices.
And this isn’t the only leftover chicken omelette recipe you can use chicken for.


How to make this Chicken Fajita Omelette
Ready to start cooking? I have a few basic tips for getting the texture of chicken fajita omelettes.
Sauté the vegetables first
Start by tossing the vegetables with a little olive oil. When the vegetables are nice and soft, transfer them to a plate until it’s time to add them to the omelette.
Tip: Cooking the vegetables first will ensure they are soft and remove some of their water so you don’t end up with too much water in your omelette.
For presentation, you can save a few cooked peppers to put on top of the fajita chicken omelettes before serving to add color.
Add the vegetables as soon as the bottom of the egg is set
Then, pour the beaten egg into the pan. Wait for a while and then add the toppings.
TIP: Do not add filling to your omelette until the eggs are slightly cooked on the bottom. This will prevent the vegetables and chicken from sinking to the bottom.
However, you also don’t want to wait so long that you won’t be able to close and seal the omelette. Ideally, you can add the filling when the bottom of the egg is set and the top is just starting to pop.
Tips for making a chicken fajita omelette
Once all your filling is added, it’s time to fold.
Calling all omelette lovers: Here’s the perfect spatula for folded omelettes!
Although it tastes delicious no matter how you fold it, I didn’t fold it all over so you could see the chicken and vegetable filling inside.
To make sure the cheese melts well, sprinkle it on top while the omelette is still warm. Although you can add cheese to a chicken fajita omelette, I still recommend sprinkling half of it on top so you can see it.


What to add to your Fajita Chicken Omelette
To make this fajita omelette recipe, you will need a few ingredients:
- Onions
- bell pepper
- eggs
- Mexican spice mix
- cooked chicken
- Monterey Jack cheese
- Oil for sautéing
Onions and peppers are common fajita vegetables, but you can also add any additional vegetables you like or have in the fridge. I personally think mushrooms, spinach, or jalapeños are good additions.
For true fajita flavor, this fajita seasoning is the best. Of course, you can also make your own, like this recipe.
Toppings for chicken fajita omelettes
For a full fajita experience, I like to top off leftover chicken omelets with guacamole, salsa, sour cream and extra cheese.
Other topping ideas include:
- Corn salsa or pico de gallo for flavor and texture
- Fresh cilantro for a pop of color
- Jalapeno food for warmth


Looking for a different way to have chicken for breakfast?
Although not a common breakfast for many of us, chicken is a healthy way to add protein to your morning. I personally find that eating a high protein breakfast helps me feel fuller for longer and gives me energy for the rest of the morning.
Lately I’ve been alternating between this chicken fajita omelette recipe and the chicken omelette with asparagus.
Another family favorite is the breakfast quesadilla with chicken recipe. In addition to protein and vegetables, these quesadillas are high in fiber thanks to wheat tortillas and black beans. It’s a hit with the kids!
For brunch parties, I like to make breakfast chicken enchiladas because I can prepare the casserole the night before. Then in the morning, all I have to do is put it in the oven and put out all the topping options for the guests to help themselves to.
And that’s not all. I have more ideas for using leftover chicken for breakfast in this post.


Chicken Fajita Omelettes are a great way to use up leftover chicken and add some veggies too
The next time you have leftover chicken for dinner, try making a simple fajita omelette. Between the roasted veggies, melted cheese, and all the toppings, it’s a very satisfying way to start the day.
I really hope this breakfast is on your table soon. It’s definitely a recipe we make when we want a filling breakfast. Any questions? Feel free to ask in the comments below.

- ½ LITTLE green bell – cut into small pieces

instructions
-
Heat a little oil in a small saucepan over medium heat. Add the onion, red bell pepper and green pepper. Simmer until everything is melted, about 5 minutes. Transfer to a plate.
-
In a large bowl, beat the eggs and Mexican seasoning.
-
In a large 12-inch (30 cm) saucepan, melt butter over medium-high heat. When the pan is hot, pour in the egg mixture. It should spread all over the bottom of the pan. Allow to cook for about 2-3 minutes, undisturbed. The egg should be completely placed at the bottom, and start looking at the top.
-
On half of the omelette, pour the onion, pepper and chicken. Gently fold the omelette over, leaving about 1 inch of space so you can see the inside of the omelette.
-
Reduce the heat to medium. Let the omelette cook for another 5-7 minutes, until the eggs are completely cooked.

Remove from heat and sprinkle with cheese. Mix with salsa, guacamole and sour cream. Serve immediately.
