These griddle steak fajitas are made with a flavorful citrus marinade and some basic Mexican spices. Sure to be the best Blackstone steak fajitas that you’ve ever made on your flat top grill or griddle!
Every now and then I cook something that the wife proclaims as “the best I’ve ever had”. And then she proceeds to request that griddle dinner over and over and over again.
That’s exactly what happened when I made these steak fajitas on the griddle recently.
In the past, I had always done a mixture of dry seasonings for my fajita steak, but I was wanting to try something new with this recipe so I experimented with a wet marinade of pineapple juice, lime juice, soy sauce, and a few other ingredients. The homemade steak fajita marinade was a winner, full of flavor and brightness and not like anything that I had ever tasted before. Even my 13 year old daughter loved it… and that’s saying a lot!
The acidity from the citrus helps to tenderize the skirt steak, and the Worcestershire and soy sauces bring a punch of boldness to compliment the sweetness from the fruits. Absolute perfection!
Here’s how to make my wife’s new favorite griddle steak fajitas:
Ingredients for Griddle Steak Fajitas
For the Fajitas:
- Skirt steak. I have always used skirt steak for this Blackstone fajitas recipe, but flank steak or sirloin would work well also.
- Bell peppers. I used a combination of orange and yellow peppers because my grocery store had them on sale, but use whatever color of peppers that you prefer.
- Tomatoes. I like tomatoes in my fajitas, but feel free to leave them out or even substitute a different vegetable like mushrooms, zucchini, or broccoli. If using tomatoes, look for a smaller variety like Campari tomatoes, because they have fewer seeds.
- Salt and pepper or all-purpose seasoning of your choice. The steak fajitas marinade in this recipe is very flavorful, so you don’t need a lot of extra seasoning for your beef and vegetables. *You can check out my Shake That All Purpose Seasoning here!
- Lime wedges for serving. Trust me, this steak is so dang good, you probably won’t need any other toppings.

How to Make the Steak Fajitas Marinade
This awesome wet marinade for steak fajitas is very easy to make. Just open a gallon sized zip top bag and add all of the wet and dry marinade ingredients. Mix everything together and add your steak.
WET MARINADE TIP:
Open a gallon sized Ziploc bag and place the bag in a saucepan. Fold the top of the bag over the sides of the saucepan a few inches. Now you can add all of your wet ingredients and juice the citrus fruits without worrying about your bag falling over and your marinade spilling out.
