How to Make Blackstone Steak Fajitas
Let’s make it together:
Preheat your Blackstone griddle over medium-high heat. The anticipation of what’s to come makes it thrilling!
Season the flank steak generously with fajita seasoning, salt, and pepper, embracing the spices that will bring your dish to life.
Add olive oil to the griddle, letting it shimmer before placing the steak on it. Cook the steak for 4-5 minutes on each side until the desired doneness is reached—think golden brown on the outside, perfectly juicy inside.
Once cooked, remove the steak from the griddle and let it rest. Resting is crucial as it allows the juices to redistribute, ensuring every bite is tender.
Next, add the sliced bell peppers and onion to the griddle. Sauté until they are soft and slightly caramelized, about 5-7 minutes. The aroma will be irresistible!
Slice the resting steak against the grain, and then mix it with the sautéed vegetables, creating a colorful and vibrant filling.
Serve on warm flour tortillas, allowing everyone to customize their fajitas with optional toppings like salsa, guacamole, or sour cream.
Delicious Variations to Try
Fajitas are wonderfully versatile! Here are some fun ways to customize your dish:
- Zesty Chicken Fajitas: Swap out the beef for chicken breast marinated in lime juice and a touch of garlic for a tangy twist.
- Vegetarian Fajitas: Substitute the steak with hearty portobello mushrooms or a mix of your favorite seasonal veggies—think zucchini and corn!
- Spicy Kick: Add fresh jalapeños or a splash of hot sauce to your sautéed vegetables for a fiery kick!
- Creamy Avocado Sauce: Instead of traditional toppings, whip up a creamy avocado sauce with mashed avocados, lime juice, and a pinch of salt for a luscious finish.
Chef Emma’s Helpful Tips
- Make Ahead: You can marinate your flank steak in fajita seasoning beforehand. This helps the flavors penetrate the meat more and save time on busy nights!
