👨‍🍳 How To Make Fajitas

For the Chicken Fajitas Marinade

  2. Place the sliced chicken into a large mixing bowl and set it to one side.
  3. In a large bowl, combine the marinade ingredients and whisk them together.
  4. Add the sliced chicken to the marinade, cover it, and place it in the fridge until the chicken is fully marinaded.

Cooking the Fajitas on the Blackstone

  1. Preheat the Blackstone griddle.
  2. Once the griddle is hot, add the avocado oil.
  3. Remove the chicken from the bowl and discard the excess marinade.

😉 Pro Tips for Perfect Fajitas

  • Be sure to have a well-seasoned Blackstone griddle! You don’t want a sticky mess!
  • Because every Blackstone is different, you need to carefully control the heat to get the perfect char on your veggies. If you’re remotely unsure, test a few pieces first!
  • The chicken cooks fast, so I add it to the Blackston after I start cooking the veggies. To avoid overcooking your veggies (I like them tender with a snap!), test them throughout the cooking process. If you are doing steak fajitas, it will also cook fast – aim for a medium-rare.
  • Even if you don’t want to use avocado oil, it’s important to use oil with a high smoke point. Your Blackstone will be getting incredibly hot, so don’t think this is something I’m saying lightly!
  • Slice your chicken thinly and evenly. This probably goes without saying, but you’ll want to make sure you have consistent slices of chicken. If not, they will cook unevenly, leaving you with some undercooked and some charred bits (AKA: no bueno!). Whether you are making chicken fajitas or steak fajitas, cut against the grain for tender and juicy bites.

 How do restaurants get their fajitas so tender?

Marinade the meat in an acid to help tenderize the meat. Let the meat marinate for 24 hours. You can help to accelerate the marinade process by storing it in a vacuum-sealed bag. Try ingredients like pineapple juice, soy sauce, or vinegar.
Also, be sure to cut the meat across the grain. This prevents the sliced meat from being chewy and allows the natural fibers in the meat to tear apart more easily when eaten.
And don’t overcook the meat. For steak, cook it to a perfect rare or medium-rare. For chicken breast, don’t cook it any higher than a 160°F to 165°F internal temperature.

What’s the best way to reheat fajitas?

If you need to reheat your Blackstone fajitas, put the filling in the microwave for short bursts of 30 seconds. Adding a bit of water to your container should help the chicken stay moist. The important thing is not fully cooking them again. You just want to make sure the filling is fully warmed through.

Heat the tortillas on a griddle, either the Blackstone or on your stove.

What are the best toppings for fajitas?

Oh man, the options are virtually endless! Salsa and Pico de Gallo are classic options, but you can’t go wrong with sour cream, guacamole, corn, or cheese. If you want a bit of extra crunch, throw some lettuce into the mix.

How do I prevent veggies from sticking to the Blackstone griddle when making fajitas?

It’s important to oil up your griddle properly before adding any vegetables. Use a large turner or spatula to spread the oil across the griddle. Pair that with plenty of mixing and scraping on the grill, and you should have a stick-free experience on your hands! It is also essential to have a properly seasoned griddle.

🤔 Fajitas – Substitutions and Variations

You can easily switch out the chicken in this recipe with pork, shrimp, or beef. Just make sure you don’t overcook it! If you want to go veggie, use tofu in place of the meat or just focus on the veggies!

Blackstone steak fajitas are another great option. Replace the chicken with either flank or skirt steak. Slice it across the grain, nice and thin, before adding it to the marinade.

I like to use a large blend of seasonings to whip up these Blackstone fajitas. But if you’re short on time, you can use a packet mix of taco or fajita seasoning!

If you want even hotter fajitas, add hot sauce or cayenne powder to your marinade!

⏱️ Storing and Reheating Leftover Fajitas

You can place any leftovers in an airtight container in the fridge for up to 4 days.

You can technically freeze the uncooked combination of veggies, spices, and chicken – but these Blackstone fajitas taste best fresh or reheated!

If you have the time, reheat the fajitas filling on the Blackstone. Heat them on a well-oiled, low-med heat griddle until warmed through. For extra points, use a basting dome and cover the fajita mixture while it heats up. Splash in some water under the basting dome to keep things moist.

You can also heat up the leftovers in the microwave, using short 30-second bursts until it is warmed through.

  • Every Blackston is different. Control the heat to get the perfect char on the veggies without burning them.

  • Use an instant-read thermometer to get the perfect cook on your meat. For chicken breast, target 160°F to 165°F internal.
