Blackstone chicken fajitas are one of those meals that instantly feel like a win. You get juicy, well-seasoned chicken, tender peppers and onions, and that signature sizzling finish right on the griddle. The high heat of the Blackstone gives everything a slight char that adds so much flavor, while also cooking everything fast and evenly.

This is a go-to recipe when you want something quick, customizable, and perfect for feeding a group. It is also great for meal prep since the leftovers reheat well and can be used in bowls, wraps, or salads. Once you make fajitas on the Blackstone, it is hard to go back to cooking them any other way.

Ingredients Needed for Blackstone Fajitas

- Skinless chicken breasts, sliced into thin strips - Theyโre lean and quick-cooking and always come out juicy and tender. Use an instant-read thermometer to make sure that the chicken is not over cooked. When reading labels for chicken breasts try to find ones that say Organic or Free Range.
- Bell peppers - Use a mix of colors like red, green, and yellow for flavor and visual appeal.
- Onion - Yellow or white onions work best and add sweetness as they cook.
- Olive oil - Use an organic olive oil, I really like the Simply Nature brand from Aldi.
- Chicken fajita seasoning - You can use a store-bought blend or make your own with chili powder, cumin, paprika, garlic powder, and onion powder.
- Tortillas - I really like the Street Style zero net carb tortillas from Mission. Flour or corn will work.
- Optional toppings for fajitas: shredded cheese, sour cream, guacamole, salsa

How to Make Blackstone Fajitas
Step 1: Preheat your Blackstone griddle to medium-high heat. Grease the Blackstone griddle with oil and spread it out.
Step 2: Once the griddle is hot, add the chicken and vegetable mixture to the griddle. Season the chicken and vegetables with Fajita seasoning.
Recipe Note: This can also be made on a Ninja Foodi Outdoor Grill with the griddle attachment plate. I actually made this recipe on both.

Step 3: Cook, stirring occasionally with a spatula, until the chicken is cooked through and the vegetables are tender and slightly charred, about 8-10 minutes.

Serve on tortillas with desired toppings. Enjoy!
Pro Tips for Blackstone Chicken Fajitas
- Slice everything evenly so it cooks at the same rate.
- Do not overcrowd the griddle. Cook in batches if needed to avoid steaming.
- Let the chicken sit undisturbed at first to develop a good sear.
- Use chicken thighs if you want extra juicy results.
- Add a squeeze of fresh lime juice at the end for the best flavor.
Storage
Store leftover chicken fajitas in an airtight container in the refrigerator for up to 4 days.
To reheat, place the mixture back on the Blackstone or in a skillet over medium heat until warmed through. You can also microwave it, but reheating on a hot surface helps maintain texture.
You can freeze the cooked chicken and vegetables for up to 2 months. Thaw in the refrigerator before reheating.
Serving Suggestions
Serve Blackstone chicken fajitas with warm tortillas and classic toppings like sour cream, shredded cheese, 3 Ingredient Guacamole Recipe, and Smoked Salsa.
They also work great as Weight Watchers Burrito Bowls Low Smart Points with rice, beans, and lettuce for a lower-carb option.
You can use the leftovers in salads, wraps, or even quesadillas the next day.
For a complete meal, pair them with sides like grilled corn, chips and salsa, or seasoned rice.
Recipe FAQs
Yes, but you will miss out on the fresh sear and flavor from cooking it on the griddle.
Chicken thighs are more flavorful and stay juicy, but chicken breasts are a leaner option.
Do not overcook it and consider using thighs for extra moisture.
