What You’ll Need for Perfect Pellet Grill Chicken Fajitas
Before we dive into the cooking process, let’s make sure you’ve got everything you need:
- Boneless, skinless chicken breasts (or thighs if you prefer juicier meat)
- Bell peppers (red, green, yellow – mix it up!)
- Onions (I like red onions, but any type works)
- Fajita seasoning (store-bought or homemade)
- Olive oil
- Tortillas
- Your favorite toppings (guacamole, sour cream, salsa, etc.)
- Reliable meat thermometer (seriously, don’t skip this!)
- Pellet grill (duh!)
Preparing Your Chicken Fajitas
The secret to amazing fajitas starts way before they hit the grill. Here’s how I prep mine:
-
Marinate the chicken – For the best flavor, marinate your chicken breasts in your favorite fajita seasoning mixed with a bit of olive oil for at least 30 minutes, but 4 hours or overnight is even better!
-
Slice your veggies – Cut bell peppers and onions into thin strips. I usually toss these with a bit of olive oil, salt and pepper.
-
Preheat your pellet grill – This is crucial! Set your pellet grill to 400°F-450°F and let it fully preheat. This high heat gives you that perfect sear while keeping the inside juicy.
How Long to Cook Chicken Fajitas on a Pellet Grill
Alright, now for the main event – the actual cooking process
Cooking the Chicken
-
Place your marinated chicken breasts directly on the preheated grill grates.
-
Cook for 6-8 minutes on the first side. Don’t fiddle with them during this time – let them develop those beautiful grill marks!
-
Flip the chicken and cook for another 6-8 minutes on the second side, or until the internal temperature reaches 165°F. Always use a meat thermometer to check!
-
Remove the chicken from the grill and let it rest for 5 minutes before slicing. This is super important – it lets the juices redistribute throughout the meat instead of spilling out when you cut it.
-
Slice the chicken against the grain into strips.
Cooking the Vegetables
There are two ways I cook the veggies for fajitas:
Option 1: Cook directly on the grill
- Place the seasoned vegetable strips directly on the grill for the last 5-7 minutes of chicken cooking time.
- They should get slightly charred but still maintain some crunch.
Option 2: Use a cast-iron skillet
- Place a cast-iron skillet on the grill while it’s preheating.
- Add a touch of oil, then cook your vegetables for about 5-7 minutes until they’re tender-crisp.
- This method gives you that classic “sizzling fajitas” presentation if you bring the hot skillet to the table!
Different Methods for Cooking Chicken Fajitas on a Pellet Grill
Based on the forum discussions I’ve read, there are a couple different approaches that work well:
Method 1: High Heat All the Way
This method, recommended by some pellet grill experts, involves:
- Preheating to 460°F
- Cooking chicken breasts for about 15 minutes per side
- Flipping only once
- Aiming for internal temp of 160°F (it’ll rise to 165°F while resting)
Method 2: Low and Slow, then Sear
This two-step method can give you extra smoky flavor:
- Start at a lower temp (around 180-200°F) until internal temp reaches 110-120°F
- Crank the heat up to 400-450°F to finish cooking to 165°F
Both methods work great – I personally prefer the high heat method for weeknight cooking since it’s faster, but the low-and-slow method gives amazing flavor for weekend cookouts when I’ve got more time.
Why Cook Fajitas on a Pellet Grill?
You might be wondering why bother cooking fajitas on a pellet grill when you could just use a stovetop. Well, here’s why I’m obsessed with doing them on my pellet grill:
- Amazing smoky flavor that you just can’t get indoors
- Even cooking temperature across the entire grill surface
- No messy stovetop splatter to clean up afterward
- Great for entertaining – more space to cook large batches
- Keeps the heat outside during summer months
Serving Your Pellet Grill Chicken Fajitas
Once everything is cooked to perfection, it’s assembly time! Here’s how I serve up my fajitas:
-
Warm your tortillas on the grill for about 30 seconds per side.
-
Layer chicken strips and grilled veggies on each tortilla.
-
Add your favorite toppings – I’m all about guacamole, fresh cilantro, lime wedges, and a bit of queso fresco. My kids go crazy for sour cream and cheese!
-
Serve with sides like Spanish rice, black beans, or grilled corn for a complete meal.
Troubleshooting Common Chicken Fajita Problems
Even experienced grillers run into issues sometimes. Here are some common problems and how to fix them:
Dry Chicken
- Problem: You overcooked it past 165°F internal temperature.
- Solution: Always use a meat thermometer and pull the chicken off a few degrees early (around 160°F) as it’ll continue cooking while resting.
Rubbery Chicken
- Problem: Likely cooked too quickly at too low a temperature.
- Solution: Make sure your grill is fully preheated to at least 400°F before adding chicken.
Bland Flavor
- Problem: Insufficient marinating time or seasoning.
- Solution: Marinate longer (at least 4 hours for best results) and don’t be shy with the seasonings!
Burnt Outside, Raw Inside
- Problem: Grill temperature too high or chicken breasts too thick.
- Solution: Consider butterflying or pounding thicker breasts to even thickness before grilling.
Final Thoughts
Cooking chicken fajitas on a pellet grill might take a little practice to get perfect, but I promise it’s worth it! The combination of smoky flavor and tender, juicy chicken can’t be beat.
Remember that timing is key – 6-8 minutes per side at 400-450°F should give you perfectly cooked chicken every time, but always verify with a meat thermometer to be sure. And don’t forget to let that chicken rest before slicing!
The best part about fajitas is they’re so customizable. Once you’ve got the basic cooking technique down, you can experiment with different marinades, toppings, and sides to make them your own.

Happy grilling, and enjoy those delicious smoky chicken fajitas!
Step 3: Cook the chicken
Drain the chicken and discard the marinade. In the same cast-iron skillet, cook chicken over medium-high heat for five to six minutes or until no longer pink. Return the pepper mixture to the pan and heat through.
Editor’s tip: No need to cook until the vegetables are soft. The filling should be crisp and slightly browned.
Step 2: Saute the vegetables
In a large cast-iron skillet, saute the peppers and onions in the remaining oil until crisp-tender. Remove from the pan and keep warm.
