This sheet pan dinner has quickly become one of my favorites. First, it comes together in less than 30 minutes and clean up is a breeze. Second, flavorful chicken is always a hit with my family (check out the tips for tender chicken below the recipe).  Third, the ingredients are usually part of my staples and the toppings can vary based on what’s in the fridge. And finally, leftovers are equally delicious and make a great wrap for lunch the next day – my kids don’t even bother reheating anything – they just fill their tortilla and go!

How to Get Tender Chicken Fajitas

I like using boneless, skinless chicken breasts for this recipe because they make ideal fajita strips. Boneless, skinless chicken breasts are also a staple ingredient in my house – I always keep some in my freezer. Ideally, I would thaw frozen chicken breasts the night before – but sometimes I don’t know what I’m making until 2 minutes before supper! Just in case that ever happens to you, I’ve included instructions for thawing chicken breasts in the microwave in the tips below. If you’re using thawed or fresh chicken breasts for this recipe, go directly to Step 2.

Step 1 – Thawing Frozen Chicken Breasts

  • If you remember, thaw frozen chicken breasts the night before by placing the wrapped chicken in a container on the bottom shelf of your fridge for 12-16 hours.
  • For last minute thawing, use your microwave to thaw frozen chicken breasts. To ensure you don’t end up with partially cooked chicken – use the defrost setting or 30% power. Place chicken breasts on a large plate and defrost for 2 minutes per breast (e.g. 6 minutes for 3 breasts). Remove chicken from microwave, take off any packaging and separate breasts if possible. Continue using the defrost setting for 2 minute/breast intervals until chicken is thawed.
  • Always follow safe chicken handling practices. Thawing chicken on the counter or the sink is not an option.

Step 2 – Prepping the Chicken Breasts

  • Use a sharp knife and a cutting board that can go in the dishwasher and is dedicated to just the chicken. Do not cut chicken and veggies on the same board – ever!
  • Remove the filet from the breasts (if present) and trim any excess fat or tendons from the chicken as you desire.
  • Even out the thickness of the chicken breasts. Place a breast on a cutting board and cover with plastic wrap. Use a rolling pin, heavy glass or the flat side of a meat mallet to gently but firmly even out the thickness of the chicken breast. You want a nice even thickness across the breast – not a pancake so don’t pound too hard and don’t use the pointy tenderizer side of the meat mallet.

Step 3 – Cutting the Chicken Breasts

  • Place a chicken breast on cutting board so the long side of the breast is parallel to the long side of the cutting board.
  • Hold the chicken firmly in place with your free hand (curl under your finger tips), then use long even strokes to cut 1/4 to 1/2 inch (.6 to 1.2 cm) slices across the breast at a slight angle.
  • Place slices on clean plate and repeat with remainder of the chicken.

In no time at all, you’ll have your chicken fajitas on the pan, ready to go in the oven.

How To Use a Meat Thermometer for Tender Chicken Pieces

Another way to ensure your chicken is nice and tender is to use a meat thermometer. Not only is using a meat thermometer good for making sure meat is cooked to a safe temperature, it can help prevent you from overcooking your chicken. For boneless chicken strips and pieces, Manitoba Chicken Producers recommend an internal temperature of 165°F or 74°C.

They also recommend letting chicken rest for 5-10 minutes before serving.

Serve your fajitas direct from the sheet pan or get fancy and serve on a platter – your call.

The fresh toppings we serve with our fajitas changes every time we make them. Sometimes we add salsa and sour cream, other times it’s refried beans and fresh slices of avocado and sometimes, as shown below it’s shredded cabbage and avocado lime sauce.
