Instructions to Make Blackstone Fajitas Step by Step

Cooking Blackstone Fajitas step by step is all about prep, heat control, and flavor layering. Follow this easy guide to nail the recipe every single time.

Step 1: Marinate the Chicken

Start by whisking together the avocado oil, lime juice, chili powder, salt, garlic powder, cumin, and cayenne pepper. Pour the marinade over your sliced chicken in a large dish or zip-top bag. Massage it gently so every piece is coated. Pop it in the fridge for about two hours—this gives the flavors time to mingle and tenderize the meat. If you’re short on time, even 30 minutes will do, but trust me—the longer, the better.

Step 2: Preheat and Prep the Blackstone

About 15 minutes before cooking, take your chicken out of the fridge to bring it closer to room temperature (helps it cook evenly). Then, heat your Blackstone Griddle to medium-high. Add a light coating of oil—avocado oil works best here since it can handle high heat.

Step 3: Sear the Chicken

Once your griddle is hot, lay the marinated chicken strips on one side. Don’t overcrowd—give them space to sear. You should hear that satisfying sizzle! Cook for about 3–4 minutes on each side until they’re golden brown and cooked through. The Blackstone’s even heat gives them a caramelized crust that’s simply unbeatable.

Step 4: Cook the Veggies

While your chicken finishes up, toss the onions and bell peppers on the other side of the griddle. Add a touch more oil and sprinkle with a pinch of salt. Cook for 5–7 minutes, stirring occasionally until they’re softened and lightly charred. The trick here is balance—you want them tender but still with a bit of bite for that perfect fajita texture.

Step 5: Combine and Warm the Tortillas

Once both the chicken and veggies are cooked, mix them together on the griddle to marry the flavors. Toss them gently for about a minute so everything gets coated in those smoky juices. Meanwhile, toss your tortillas on the griddle for about 30–60 seconds per side, just enough to get them warm and pliable.

Step 6: Assemble and Serve

Now comes the fun part—building your fajitas! Lay out a warm tortilla, pile on the chicken and veggies, and top with cheese, sour cream, and a squeeze of lime. Add salsa, tomatoes, or cilantro if you’re feeling fancy. These fajitas are best served hot off the griddle, family-style, with everyone assembling their own just the way they like.

What to Serve with Blackstone Fajitas

Fajitas are a meal on their own, but adding a few sides turns them into a feast. Think Mexican rice, refried beans, or a simple avocado salad. A cold pitcher of homemade lemonade or margaritas also pairs beautifully with that smoky, spicy kick. You can even serve these fajitas alongside Chicken Caesar Pasta Salad for a creative Tex-Mex twist on classic favorites.

Key Tips for Making Blackstone Fajitas

1. Marinate Longer: Two hours is great, but overnight is golden.
2. Don’t Overcrowd the Griddle: Crowding traps steam and prevents browning.
3. Use Fresh Lime: The acidity brightens everything and balances the spice.
4. Slice Evenly: Keep your chicken and veggies in uniform strips for even cooking.
5. Rest Before Serving: Let your cooked chicken sit for a minute before serving to keep it juicy.
6. Add Variety: Try adding mushrooms, zucchini, or jalapeños for a fun twist.
7. Keep It Warm: If cooking in batches, use one side of the griddle on low heat to keep everything hot.

Storage and Reheating Tips for Blackstone Fajitas

Leftovers? You’ll be thrilled to know these taste just as good the next day. Store everything (meat and veggies) in an airtight container in the fridge for up to 3 days. Reheat them on the griddle or in a skillet over medium heat until warm—this keeps that lovely char. You can also microwave them in a pinch, though you’ll lose a bit of crispiness. Tortillas can be reheated wrapped in foil in the oven or a few seconds in the microwave.

If you want to meal prep, store the marinated raw chicken separately from the veggies, then cook everything fresh when you’re ready to eat. For a freezer-friendly option, portion the cooked fajita mix into freezer bags—lay them flat for easy storage. They’ll keep well for up to two months.
