Fajitas are such a mealtime win, aren’t they? They take such little work and are loaded with bold flavors the whole family will enjoy.

Sometimes we enjoy this chicken in tortillas (the classic way) but other times I love to serve them up on rice or lettuce.

And then of course there are so many toppings you can add to customize this delicious meal for each individual person. Want cheese? Add a sprinkle of shredded cheddar or crumbled feta! Love avocado? Add a few slices or guacamole! The list of possible toppings is long and however you serve up this chicken, you’ll be pleased!

For this recipe you’ll need (full list of ingredients and instructions are in the recipe card below):

  • Chicken breasts
  • Olive oil
  • Lime juice
  • Onion
  • Bell Peppers
  • Seasonings

We’ll start by slicing the chicken into strips. While you could of course sauté the chicken breasts whole, I’ve found that taking the extra two minutes to slice them means you’ll get more of that marinade on each bite.

Then toss the marinade ingredients and chicken together to marinate for at least 30 minutes. This gives your chicken so much flavor! That lime gives it all a bright punch that I really love!

Slice the peppers and onion into thin strips. Sauté both in olive oil in a large skillet so they start to get tender and have some charred edges. Then add your marinated chicken so that it cooks through.

That’s it! Now you’re ready to serve in a variety of ways. (I’ve listed my favorite serving ideas below.)

Is homemade fajita seasoning worth it?

Heck yes it is. While you can certainly use store-bought taco or fajita seasoning, I highly recommend making your own with just a few ingredients. It doesn’t take much time at all, but it produces some big flavor! And then you know that you’re avoiding all the unnecessary additives that often go into seasoning blends you’ll find at the grocery store.

Can you use chicken thighs?

Absolutely. You can always use boneless skinless thighs if you prefer.

What color bell pepper is best to use in fajitas?

I love a mix of colors! I usually use one green and one yellow, orange, or red. But any color bell pepper will work beautifully!

What color onion is best for fajitas?

White, yellow, or red onions are all great in fajitas. I tend to grab the red onion because I love that it’s a bit sweeter than the others and the color is so pretty with the other ingredients.

How long should you marinate the chicken

I always like to marinate this chicken for at least 30 minutes and up to 12 hours. The longer you marinate the more pronounced the flavor will be. I don’t recommend longer than 12 hours because your meat can start to breakdown and the texture changes if it sits in a marinade for too long. (That goes for any marinade.)

Are chicken fajitas good for meal prep?

They’re so great for meal prep, friend! Just portion out what you want to enjoy for the next few days in airtight containers. Store in the refrigerator for up to 5 days. Reheat on the stovetop or in your microwave.

How to serve this

The obvious way to serve these Skillet Chicken Fajitas is of course in tortillas. Load them up with the chicken, peppers, and onion. Serve with a side of rice!

Want to do something a bit different but still super satiating? I love to throw mine on Skillet Breakfast Potatoes or white rice.

Thinking of going more low carb? This chicken is delicious on Cilantro Lime Cauliflower Rice or on lettuce.

Whatever you choose to do with it, don’t forget to add your favorite toppings! Some ideas are Guacamole, Pico de Gallo, store-bought salsa, black beans, shredded cheese, feta crumbles, sour cream, avocado slices, and/or fresh cilantro. There’s so much you can do!
