How to Make Blackstone Steak Fajitas
Ingredients
- 1 lb flank steak
- 1 bell pepper, sliced
- 1 onion, sliced
- 2 tablespoons olive oil
- 2 teaspoons fajita seasoning
- Salt and pepper to taste
- Tortillas
- Optional toppings: guacamole, sour cream, salsa

Directions
Preheat your Blackstone griddle to medium-high heat, around 375°F. Allow it to warm up for about 5 minutes.
In a large bowl, toss the sliced flank steak, bell pepper, and onion with the olive oil and fajita seasoning. Ensure everything is evenly coated. Add salt and pepper to taste, mixing well.
Once the griddle is hot, place the seasoned steak on the griddle and cook for about 3-4 minutes on each side. Use tongs to flip the steak, cooking until it reaches your preferred doneness—look for an internal temperature of 135°F for medium-rare.
After the steak has cooked through, add the sliced bell peppers and onions to the griddle. Cook until they are softened and slightly charred, stirring occasionally, for about 5-7 minutes. You’ll know they’re done when they are tender and fragrant.
Remove everything from the griddle and let the steak rest for about 5 minutes to retain its juices before slicing it against the grain into thin strips.
Serve the sliced steak and sautéed veggies in warm tortillas. Encourage everyone to add their favorite toppings for a customizable dining experience.
How to Serve Blackstone Steak Fajitas
These fajitas are best enjoyed hot and fresh. For an appealing presentation, serve them garnished with fresh herbs, avocado slices, or a sprinkle of lime zest. Consider pairing them with a side of Spanish rice, black beans, or a fresh tomato salad for a complete meal. A chilled margarita or a light beer makes for an excellent drink partner to balance the hearty flavors. Feel free to set up a toppings bar with guacamole, salsa, and sour cream, inviting guests to personalize their fajitas to their liking!
How to Store Blackstone Steak Fajitas
If you have any leftovers, place them in an airtight container and store them in the refrigerator for up to 3 days. For longer storage, you can freeze the cooked steak and veggies. To do this, let them cool completely, then transfer to a freezer-safe bag, removing as much air as possible. They should maintain quality for up to 3 months. When ready to enjoy again, thaw in the refrigerator overnight and reheat on the stovetop or griddle until heated through, ensuring the steak remains juicy and flavorful.
Tips to Make Blackstone Steak Fajitas
Prep in Advance: Slice your veggies and marinate the steak the night before to save time.
Ingredient Swaps: If you’re out of flank steak, try chicken breast or shrimp for a different protein option.
Avoid Overcrowding: Cook in batches if necessary to prevent steaming; give everything enough space to sear nicely.
Use Room Temperature Ingredients: Let steak and veggies come to room temperature for even cooking.
Batch Cooking: Make extra meat to keep in the fridge for salads or wraps throughout the week.
Enhance Flavor: Marinate the flank steak in lime juice and garlic beforehand for an extra punch.
Restaurant Style: Finish the steak with a squeeze of fresh lime juice right before serving for freshness.
Dietary Adaptations: Use gluten-free tortillas if necessary.
Leftover Fajitas: Transform the leftovers into fajita quesadillas or a hearty breakfast scramble.
Storage Tips: Opt for glass containers for refrigeration to avoid stains and flavors mixing.
Variations
Vegan Fajitas Delight: Swap the flank steak for portobello mushrooms or marinated tofu for a plant-based version that satisfies even the biggest meat lovers.
Tropical Chicken Fiesta: Try chicken breast marinated in pineapple juice and soy sauce for a sweet and tangy twist, complemented by fresh cilantro.
Keto-Friendly Fajitas: Skip the tortillas and serve the steak and veggies over a bed of lettuce, topped with avocado and cheese, for a delicious low-carb meal.
Spicy Chipotle Fajitas: Add chopped chipotle peppers in adobo sauce to the seasoning mixture for a smoky and spicy kick that elevates the traditional flavor profile.
Mediterranean Twist: Incorporate Mediterranean spices like oregano and thyme, and serve with tzatziki sauce for a unique blend of flavors.
