This is such an easy, weeknight meal that doesn’t require many ingredients and ends up SUPER tasty!  I love it!  Husband approved, too – he always goes back for seconds!  Reheating this for leftovers is quite yummy, as well.

Chicken Fajitas in the Oven

  • Servings: 2-4
  • Difficulty: easy
  • Print


  • 2-4 boneless, skinless chicken breasts, trimmed
  • 1-2 Tbsp Taco seasoning mix (the link is to the one I use from Trader Joe’s; you can purchase in a Trader Joe’s store or on Amazon)
  • 1 red bell pepper, sliced
  • 1 green bell pepper, sliced
  • ½ red onion, sliced
  • ¼ – ½ cup shredded sharp cheddar cheese (I actually ran out and tried mozzarella cheese on one of the chicken breasts pictured – still tasted great!)
  • 1 jalapeno, chopped (optional)
  • ½ avocado, sliced (optional)
  • Salsa or hot sauce for topping (optional)


  • Preheat oven to 375°F
  • Spray oven safe cooking pan (I usually use a glass container) with olive oil spray
  • Season both sides of each piece of chicken with taco seasoning mix (spread out the 1-2 Tbsp evenly)
  • Place sliced onions, bell peppers, and jalapeno (if using) over chickenIMG_20171203_181913
  • Place in oven and cook for 25-30 minutes, until chicken is cooked through (until at least 165F internal temp)
  • Remove from oven, sprinkle cheddar cheese evenly on each chicken breast. Return to oven for 3-5 minutes, until cheese is melted
  • Top with avocado, salsa, or sriracha sauce to taste! Enjoy!  May also serve this over brown rice, but I’ve found that we’re often stuffed without the added rice!

As I noted in the ingredients, I ran out of sharp cheddar cheese so I placed mozzarella on another piece of chicken – still tasted great.  Or you have the option of no cheese, if dairy doesn’t sit well with you!  Very versatile!IMG_20171203_190015

This recipe is so convenient – it takes hardly any time to chop up the veggies and season the chicken while the oven is pre-heating. Then pop it in and just wait!  With a mix of vegetables, protein, and healthy fats, it serves as a healthy AND tasty dish
