Blackstone Steak Fajitas Are a Quick Healthy Dinner
Blackstone steak fajitas are a quick healthy dinner you can throw together on busy nights. These steak fajitas are much better than what you’d find at a Mexican restaurant because you control the quality of ingredients. Best of all, there are leftovers for work lunches!
This Blackstone steak fajitas recipe is so easy and delicious I make it a few times a month. To warn you, this recipe makes a lot. Consider scaling the recipe back if you do not need leftovers and aren’t feeding an army.
Don’t Have a Blackstone? No Problem!
If you don’t have a Blackstone, you can still make this recipe. Use a cast-iron skillet, cook on a high temp and try not to stir too often.
Customize Steak Fajitas Recipe For Your Family
This recipe is highly customizable. If you prefer more meat, add more meat or if you are like me and prefer more veggies, then load up on veggies. If you prefer chicken or shrimp to steak, then swap them out. Remember to adjust cooking time for shrimp since it cooks so quickly.
I’m not a big fan of bell peppers, so I replace most bell peppers typically found in steak fajitas for some poblano or pasilla peppers. I also try and keep the dish low carb, so I skip the flour tortillas (even though I LOVE tortillas, I love my pants fitting more).
Blackstone Steak Fajitas Ingredients
Here’s what you’ll need to make this fajitas recipe
Steak Fajitas + Marinade
- Beef (chicken or shrimp)
- Avocado oil or your favorite oil
- Lime juice
- Minced garlic
- Chili powder
- ground cumin
- Pepper flakes
- Black pepper
- Salt
Veggies for Steak Fajitas
- White onion
- Bell pepper
- Pasilla or poblano pepper
- Zucchini
- Roma tomatoes
How to Make Blackstone Steak Fajitas Recipe
The first step is to cut the steak into bite-sized pieces. Now it’s time to mix the marinade ingredients into a large glass bowl.
Stir marinade to combine.
Fold in the bite-sized pieces of steak. The meat should look similar to below. Of course, everyone cuts the steak differently, so as long as the pieces are bite-sized, you can’t go wrong. My husband was hungry enough that he volunteered to cut the steak up for me.
Now it’s time to cut the vegetables up while the steak is marinating in the delicious fajitas seasoning.
As you can see below, I used several pasilla peppers, one red bell pepper, 3-4 small yellow squash, and 2-3 small zucchinis from my garden. One sliced onion is in the bottom of the bowl.
Put all the chopped veggies into one big bowl.
Now it’s time to cut up the tomato. I like to keep the tomato slices separately to add them at cooking. I like for the tomatoes to be barely cooked. If you want your tomatoes more cooked, you could add them to the big veggie bowl. I think I used four Roma tomatoes for this steak fajitas dinner.
Cooking Blackstone Steak Fajitas
Turn on the Blackstone. I turn all the burners on high, but if you prefer medium-high, that works too. Spread a thin layer of avocado oil or your favorite cooking oil on the grill.
Pour the big veggie bowl on the heated Blackstone griddle when the grill is heated. Spread the vegetables out into a thin layer. THIS is what makes cooking on the Blackstone so wonderful. Foods cook from the heat and do not sweat. The juices you would typically see if you were cooking these fajitas in a skillet won’t exist on the Blackstone because the food isn’t sweating.
Splurge on a Blackstone Grill – It’s Worth it!
If you don’t have a Blackstone, I highly recommend buying one. They are great to cook with outside when your kitchen is clean, and you don’t want a mess or when you don’t want to heat the house. Also, the food tastes so wonderful cooked on a Blackstone. It’s like really great camping food.
If you think about it, cooking on a Blackstone is how restaurants cook, griddle style. The clean-up is so easy too.
Season the vegetables with salt, black pepper, and garlic powder. Cook veggies until they are about halfway done. Then push the veggies to one side of the Blackstone and turn down the heat on that side to low.
Add another light, thin layer of oil to the empty side of the Blackstone where you will be cooking the fajitas on the grill.
Dump the steak fajitas meat onto the grill and spread it out so that it doesn’t sweat. Cook the steak for 2-3 minutes without stirring. The goal here is to get that wonderful char on the meat.
This is what the steak looked like after I flipped it.
Continue cooking the steak fajitas meat. Let the meat cook for several minutes before stirring. Again we are looking for the CHAR.
When the meat is done to your liking, add the tomatoes and cook for a few minutes. Flip the zucchini veggie mixture in the same area.
When the tomatoes are done to your liking, combine the steak/tomatoes mixture with the zucchini veggie mixture—taste for seasoning. You may have to add a little salt, black pepper, and garlic powder.
Blackstone Steak Fajitas Recipe Optional Additions

- Tortillas – These steak fajitas taste excellent with the ingredients rolled up in a flour or corn tortilla.
- Sour cream
- Cheese – Crumbled Mexican cheese or shredded cheddar
- Lettuce or Cabbage – Shredded
