How to Make Chicken Fajitas on the Grill

• Step 1 – Prepare the Chicken – First, I like to the filet the chicken. This way they are roughly about the same size about 1 inch thick.  This ensures that they all take about the same time to cook. They’ll be ready around the same time on the grill.

• Step 2 – Cut chicken into strips – To filet a chicken breast, you cut it in half long wise. It’s not as thick as the chicken breast is in its original state.  If your chicken breasts are thinner, this step would not be required.

• Step 3 – Combine Chicken and Seasoning – Next, I put the chicken breasts and then pour fajita seasoning in a bag. Then shake so the chicken is thoroughly coated with this seasoning.

• Step 4 – Drizzle with Oil and Lime – Then you add the chicken to a small bowl.  Next you drizzle the oil and squeeze the fresh lime juice over the chicken.

• Step 5 – Allow Chicken to Marinate – Stir these ingredients to combine in the chicken fajita marinade. Then allow the chicken breasts to marinade for at least 20 minutes. 

• Step 6 – Marinate overnight if possible – I like to do this part the night before. So that the chicken has plenty of time to soak up the delicious flavor from the fajita marinade in the plastic bag.

• Step 7 – Grill Chicken – After the chicken marinades, place chicken breasts on a pre-heated grill or on grill pan.  Next, cook the chicken on the grill on medium high heat for at least 20 minutes (10 minutes per side).
  
• Step 8 – Remove Chicken – Once the chicken is finish grilling, remove from the grill.

Prepare the Peppers and Onions

• Step 1 – Cut Peppers and Onions – Next cut the bell peppers into quarters. Then slice the onions into fat rings so they don’t fall through the grill grate.

• Step 2 – Grill Vegetables – Then place the cut peppers and onions directly on the grill. This makes the best Grilled Chicken Fajitas Recipe!
• Step 3 – Continue cooking – Grill the peppers and onions for approximately 5 minutes. Or until they are the tenderness that you prefer for your fajita recipe.

How to Heat up Tortillas

• Step 1 – Grill the Tortillas – Next you place the flour tortillas on the grill to heat them as well.  I prefer to put them on the bottom rack so that they get these beautiful grill marks.

• Step 2 – Assemble Chicken Fajita – Slice the grilled chicken, peppers, and onions. Assemble with your cooked flour tortillas, chicken and veggies and serve with your favorite side dish and toppings.

Are Fajitas Better on Grill or Skillet?

It depends on the flavor that you are wanting. If you prefer a smoky flavor, then I would cook fajitas on the grill. But if it to cold to cook outside we prefer Fajitas in a cast iron skillet.

The chicken cooks with the perfect sear and tons of flavor. You may need to let the chicken cook in batches for the perfect coloring. Add your favorite topping and sides for a crowd pleasing meal. See Cast Iron Skillet Chicken Fajitas for more tips.

How to Make Grilled Chicken Fajitas in Foil
