These Blackstone Steak Fajitas are a fun and tasty way to enjoy steak! Juicy slices of beef, colorful bell peppers, and onions are cooked perfectly on a hot grill.
Pair them with warm tortillas, and you’ve got a perfect meal for friends or family. I love adding extra guacamole on top—who can resist that? 🌮
Key Ingredients & Substitutions
Flank or Skirt Steak: Both cuts are excellent for fajitas due to their rich flavor and tenderness when cooked properly. If you’re looking for a healthier option, chicken breast or portobello mushrooms can work as great substitutes.
Bell Peppers: I love using red and yellow peppers for their sweetness and color. You can substitute with green peppers for a more bitter taste or even use poblano peppers for a smoky flavor.
Spices: A blend of chili powder, cumin, garlic powder, and onion powder creates a tasty flavor base. Feel free to add some smoked paprika for a deeper flavor, or adjust spices according to your heat preference.
Tortillas: Corn tortillas are a classic choice, but flour tortillas offer a softer bite. Both options work beautifully, and you can even use lettuce wraps for a low-carb version!
How Do I Get the Steak Just Right?
Cooking steak to perfection can be tricky, but following a few steps can help. Aim for a beautiful sear while keeping the inside juicy.
- Make sure to preheat the Blackstone griddle. A hot surface ensures a good sear.
- Cook the steak for 4-5 minutes on each side, but use a meat thermometer for precision; 135°F for medium-rare is ideal.
- Let the steak rest after cooking. This allows the juices to redistribute, keeping the meat tender.

How Much Time Will You Need?
This recipe will take about 15 minutes of active cooking time, plus at least 30 minutes for marinating the steak (up to 4 hours if you want more flavor). Overall, you can have these delicious fajitas ready in about 45 minutes!
Step-by-Step Instructions:
1. Marinate the Steak:
Start by preparing the spice mix. In a bowl, combine the chili powder, cumin, garlic powder, onion powder, salt, and pepper. Rub this flavorful mixture all over your flank or skirt steak. For the best taste, let it marinate for at least 30 minutes at room temperature. If you have more time, putting it in the fridge for up to 4 hours will enhance the flavor even more!
2. Preheat the Blackstone Griddle:
While your steak is marinating, preheat your Blackstone griddle over medium-high heat. Once it’s hot, drizzle in the olive oil to prepare for cooking.
3. Cook the Steak:
Carefully place the marinated steak onto the griddle. Cook it for about 4-5 minutes on each side, depending on how well-done you like your steak (135°F for medium-rare). Once cooked to your liking, remove the steak from the griddle and let it rest for about 5 minutes to lock in the juices.
4. Sauté the Veggies:
While the steak is resting, it’s time to cook the veggies! Add the sliced bell peppers and onions to the griddle and cook for about 5-7 minutes, or until they’re nice and softened with a charred edge. Don’t forget to season them with a pinch of salt and pepper for added flavor!
5. Slice the Steak:
Now that your steak has rested, slice it thinly against the grain. This will keep the meat tender and easy to chew, which is just what you want for fajitas!
6. Serve:
For serving, take a large platter and layer on the sautéed peppers and onions. Top everything with the sliced steak. Don’t forget to serve warm tortillas and fresh lime wedges on the side! Optionally, let everyone add their favorite garnishes like avocado, sour cream, salsa, or cheese. Enjoy your delicious Blackstone Steak Fajitas!
Can I Use a Different Cut of Beef for This Recipe?
Absolutely! While flank steak and skirt steak are traditional choices for fajitas, you can also use sirloin or ribeye for added flavor and tenderness. Just be sure to adjust the cooking time based on the thickness of the steak to achieve your desired doneness!
What if I Don’t Have a Blackstone Griddle?
No worries! You can use a regular grill or stovetop skillet instead. For a stovetop option, heat a large skillet over medium-high heat and follow the same cooking instructions for the steak and vegetables. Just make sure to use enough oil to prevent sticking!
How to Store Leftover Fajitas
Store any leftover steak and veggies in an airtight container in the fridge for up to 3 days. To reheat, you can use a skillet over medium heat, adding a splash of water or broth to keep them moist. Enjoy them wrapped in fresh tortillas or as a topping for salads!
Can I Make This Recipe Vegetarian?
Yes! You can substitute the steak with a combination of your favorite vegetables like mushrooms, zucchini, and additional bell peppers. Season them with the same spices and sauté until tender. Serve with beans or lentils for added protein!
