Why We Love This Blackstone Chicken Fajitas Recipe
Fajitas are one of my favorite meals. After all, they are simple to make and always taste great. I love the combo of flavors in the marinade and how the chicken sizzles while it cooks on the flat-top grill.
Plus, these griddle fajitas are perfect for feeding a large crowd. Serve them with tortillas, cooking rice in an Instant Pot, and our easy cook pinto beans in Instant Pot for a complete Mexican-inspired meal.
FYI, you don’t need a flat top griddle (like Blackstone or Camp Chef) to make these fajitas! So, see the recipe notes (other cooking methods) below to make them in a cast iron skillet or on an electric griddle.

Ingredient Notes and Substitutions

For The Marinade
- Olive oil – You can also use any neutral flavored oils such as vegetable or canola oil.
- Seasoning – You can use a fajita or chicken taco seasoning recipe.
- Spicy V-8 juice, Clamato juice, or red salsa
- Lime juice – This is the most important ingredient for the marinade. If you don’t have one, use lemon juice instead.
- Lime – Omit this if you don’t have one in the pantry or fridge.
- Onion – Used for both marinade and fajitas. So don’t skip this one.
For The Fajitas
- Chicken – What to make with chicken tenderloins, sliced into strips. Or use breasts if preferred.
- Vegetables – Bell pepper and onions are used for this recipe. Any color of bell pepper or type of onion can be used.
- Jalapeno pepper – This gives heat to the recipe. If you prefer less spicy, omit this or use milder pepper like a banana pepper.
- Oil – This is needed for cooking on the griddle. We used Avocado oil, but you can use any high heat oil.
- Flour tortillas – These are needed to wrap our fajitas. If you don’t have any, you can also use corn tortillas.
- Optional toppings – fresh cilantro, salsa, sour cream, or guacamole.

Recipe Variations
- Blackstone Steak Fajitas – Try these fajitas with steak instead of chicken. Just substitute the same amount of flank steak for chicken in the recipe.
- Add more spice – If you want to add some spice to your fajitas, use chili powder, hot sauce, or salsa in the marinade.
- Vegetarian fajitas – remove the chicken and double the number of vegetables. You could also try using tofu in place of chicken.
Equipment for This Recipe
- Blackstone griddle – griddle grill (or a skillet!)

How to Cook Blackstone Chicken Fajitas
- Prepare the Marinade
Put the ingredients for the marinade in a Ziplock bag. Then seal the bag and shake it to mix the marinade. Add the chicken strips and the marinade to a resealable bag and seal.

Let chicken marinate in the refrigerator for at least 8 hours. This will help the chicken absorb all of the flavors from the marinade.

Save This Recipe!
Preheat one side of the griddle to medium-high heat to 400º. This will help cook your food evenly.
Use an infrared temperature gun to check the temperature of the grill so you can make sure it is at the right temperature.
Once the griddle is ready, add 2 tablespoons of cooking oil. Then, put the bell, jalapeno peppers, and onions on the griddle.

Preheat the other side of the griddle to low heat. Cook the vegetables for 2-3 minutes, until they are starting to become softer.
Then use the metal spatula to move them to the other side of the griddle. Keep them warm at low heat.
Add the chicken to the hot side of the griddle and let it sit for 2 minutes to let it char a little before flipping it with the metal spatula.

Once you have turned the chicken, combine it with the veggies and stir frequently until the chicken is cooked through or reaches 165º internally.

Remove the fajitas from the oven and put them on a plate, then cover them with foil while you heat the tortillas.

You can then garnish fajitas with chopped cilantro, salsa, sour cream, and guacamole.

Serving Suggestions
Blackstone fajitas are a crowd-pleaser and this is part of our Cinco de Mayo recipes! To complement the sizzling flavors, consider a refreshing lime cilantro rice or avocado crema for a cool contrast. A vibrant Mexican corn salad adds a burst of texture and sweetness, while a zesty pico de gallo offers a tangy kick. Serve it with lime wedges and fresh tomatoes on the side. Shrimp or sautéed zucchini and mushrooms is also a great addition. You may add more spices like ground cumin, cayenne pepper, onion powder, paprika, or salt.
Recipe FAQs
Yellow onions are slightly sweeter than white onions. However, we prefer red onions in this recipe. They look like sticking with the bell pepper and chicken in fajitas.
You don’t have to add shredded cheese to your fajitas, but many people do. So, use a Mexican style like queso fresco or Monterey Jack.
Serve fajitas with rice and pinto beans or a green cowboy salad on the side.
Store leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm them in a skillet over medium heat until hot, or use the microwave in short bursts to avoid drying them out. Keep tortillas separate to prevent them from getting soggy, and heat them separately in a pan or microwave.
