Step 1: Ingredients and Tools

You may print the recipe here if you like.


  • 2 tsp. table salt (10g)
  • 1/2 tsp. chili powder (1g)
  • 1/2 tsp. black ground pepper (1g)
  • 2 tsp. ground cumin (6g)
  • 2 tsp. paprika (5g)
  • 4 large bell peppers
  • 1 large onion
  • 8 chicken tenderloins (about 2 lbs, approx 900g)
  • 3 to 4 garlic cloves
  • 3 to 4 tbsp of oil (olive oil, vegetable oil, etc.)
  • Avocado (optional)
  • Sour cream (optional)
  • Cheddar cheese (optional)
  • Lime juice (optional)
  • Cilantro (optional)


  • Tongs
  • Bowls
  • Knife
  • Cutting board
  • Sheet pan
  • Silicone mat or parchment paper or use kitchen spray

Step 2: Mix Those Spices

Preheat the oven to 400 F/205 C. In a small bowl combine the salt, chili powder, black ground pepper, ground cumin, and paprika. If you want yours a bit spicier add more chili powder or add in some cayenne as well. Mix them all together with a whisk or fork and set aside.

Step 3: Cut the Veggies

Wash the bell peppers and cut them however you like. I like to cut them in long strips. Slice the onion as well, again, however you like. I like to remove the outer skin and then just cut the onion in half. And then slice it about 1/4 inch wide or so. Then you can separate the pieces and add them to the bowl with the peppers. If you like some heat add a few jalapenos.

Step 4: Slice the Chicken

Now it is time to slice the chicken. I prefer to use chicken tenderloins, but you can use chicken breast, chicken thighs, etc. The tenderloins turn out nice and juicy and are very easy to work with. I usually will slice the tenderloin into 3 pieces lengthwise.

Once done add the chicken to the bowl with the veggies. Don't use your hands with the raw chicken, use tongs.

Next, add the minced garlic and the oil. You can always add more garlic or less too if you like.

Step 5: Mix in the Spices

Add the spices to the bowl. Then if you have a lid place the lid on it and shake the bowl to evenly coat the chicken and veggies. You can also just mix them with the tongs. Or place everything in a large freezer bag and shake it. After that pour out the ingredients onto a sheet pan lined with a silicone mat, parchment paper, or spray the pan with kitchen spray.

Step 6: Bake and Serve!

Bake the fajita ingredients for 20 to 30 minutes. After 10 minutes stir the ingredients so they cook evenly. The chicken should be at least 165 in the center. If you don't have a meat thermometer, slice open a piece of chicken and make sure there isn't any pink. In my oven 23 to 24 minutes is perfect.

Once the veggies are soft and chicken is done remove the pan from the oven and allow it to cool for a few minutes. During this time you can slice your avocado and prepare your other optional ingredients.

Add them to a flour tortilla and serve! Enjoy! :)
