Chicken Fajitas For One

Homemade Chicken Fajitas For One! One tender and juicy chicken breast cooked in a skillet, sliced and served with sweet onions, crisp peppers, cheese and tortillas. So easy and so delicious!

A small baking dish filled with three chicken fajitas filled with avocado slices, red and green bell peppers, and shredded cheese next to a half of an avocado and a small jar of sour cream.

This sizzling hot chicken fajitas recipe is a great go-to recipe for a quick and easy meal. Tender cooked chicken, sweet onions, and crunchy fresh bell peppers are the main ingredients needed for this fast but flavorful dish.

Healthy Chicken Fajitas

If you're looking for a healthy meal option, consider chicken fajitas. The chicken and vegetables by themselves are low in calories. If you're looking for a low carb option, use low carb tortillas or skip the tortilla altogether. One of my favorite ways to eat fajitas is by using a lettuce wrap instead of a tortilla.

For another low carb option, enjoy the cooked chicken and cooked vegetables over a plate of chopped salad greens: truly spectacular!

See recipe box below for ingredient amounts and full recipe instructions.

  • butter
  • boneless, skinless chicken breast or thigh (sliced)
  • salt and black pepper
  • sliced onions
  • sliced red or green bell pepper
  • garlic
  • 2-3 flour tortillas

Optional Fajita Toppings:

  • sliced avocado
  • shredded cheddar cheese
  • sour cream
  • chopped cilantro
  • homemade queso

How To Make Chicken Fajitas

  1. Melt the butter in a medium-sized skillet over medium-high heat. Season all sides of the chicken pieces with salt and pepper and cook 6 minutes, until all pieces are cooked through. Transfer to a plate, cover and set aside.
  2. Add the onions and peppers to the skillet (add a little extra butter or a drizzle of olive oil to the pan if needed), and cook until the onions and peppers have softened.
  3. Spoon the sliced chicken into a warm tortilla and top with the vegetables. Add cheese or slices of avocado, if desired.

Pro Tip: I prefer to season the chicken minimally. You might like to add a squeeze of lime juice, a pinch of dried oregano or ground cumin, or chopped jalapeños to the chicken and/or vegetables for extra flavor.

You could also make sheet pan chicken fajitas by cooking the chicken and the vegetables all on the same pan. Our Sheet Pan Chicken and Vegetables recipe explains the cooking process perfectly.

Tips For Making The Best Chicken Fajitas

  • Cook the chicken and vegetables separately.
  • Use whatever combination of peppers you like. You can even add more if you prefer.
  • Slice the onions and the peppers roughly the same size, this will help them cook at the same time.
  • As mentioned above, you don't need a whole lot of fancy seasonings to make this dish delicious. Season with jalapeños, lime juice, and extra garlic for lots of flavor.
  • Try adding small chunks of pineapple to your fajitas for a fresh, sweet flavor.

    Having lost my husband last June, I’m struggling with how to cook for one, yet still eat things I like. I found this recipe today and made it this evening. It was simple and delicious. I’ll be adding it to my menu rotation for the future.

    1. I’m so sorry for your loss, Karen. Thank you so much for taking the time to let me know you enjoyed the fajitas.
