Flank Steak Tacos RecipeFor these Flank Steak Tacos, I’m using my new Santa Maria attachment. The folks at Gabbysgrills.com have designed it for the 22” Weber for Santa Maria style cooking. Santa Maria grills are popular in California and they work by simply raising and lowering the cooking grate over hot coals. This attachment fits right on the weber in place of the lid and to adjust the cooking height all you do is turn the crank handle to desired height. I love the flavor that this style of cooking produces. It’s perfect for grilling meat over live fire and being able to raise the cooking grate to different levels lets you have more control of the cooking temperature. I thought it would be perfect for Flank Steak Tacos. And I’m also throwing on some veggies to use in a Fire Roasted Salsa. First the flank steak goes into a marinade for a couple hours. I combine tequila, lime juice, water, Worcestershire, fresh cilantro, garlic, salt, pepper, and cumin for the marinade. While the steak is absorbing these flavors it’s a good time to prepare the fire roasted salsa. Start a couple chimneys of B&B Hickory Lump charcoal and add them to the Weber once hot. Place the Santa Maria attachment on the grill and spray the cooking grate with vegetable spray. Give it a few minutes to get hot and adjust the cooking grate several inches above the hot coals. Place Roma tomatoes, jalapeno and Fresno peppers, onion, garlic, and lime right on the grate. Grill the vegetables for 5-10 minutes turning often. You want them to blister and char on the outside to bring out the flavor. Let everything set on the cutting board a few minutes to cool and roughly chop. Place the tomatoes, onion, peppers, and cloves of garlic in a food processor. Squeeze the lime halves and season with ground cumin, salt, and black pepper. Pulse the food processor until everything is combined and pour into bowl. Refrigerate the salsa for at least an hour. After the steaks have marinated, remove from the ziplock bag and allow the excess liquid to drip off. Lower the Santa Maria right over the coals and sear the steaks for 1 ½ – 2 minutes on each side. Raise the grate several inches and continue to cook away from direct heat until it reaches medium rare about 125-130⁰ (or your desired doneness). This is where having a Thermapen comes in real handy. Check them out here >> Remove each steak from the grill and place on a cutting board covered loosely with aluminum foil. While the steaks rest warm flour or corn tortillas on the grill. It only takes about 30 seconds on each side so don’t walk away too far. To serve these tacos; slice the flank steaks across the grain into thin strips. You can dress them with your favorite toppings. I like a good spoon of guacamole, a couple strips of flank steak, fire roasted salsa, fresh chopped onion, cilantro, a squeeze of lime, and good dash of Mexican Hot Sauce. The marinade brings a really fresh flavor to the flank steak and Fire Roasted Salsa has plenty of heat and smokiness. I love the flavor that cooking over an open fire gives food, so if you don’t have a Santa Maria Grill this attachment is a good option for the Weber. Also you can create this recipe on any grill just set it up for a 2 zone fire. Give these Flank Steak Tacos a try!. Print

Tried this recipe tonight and it was great. If it weren’t for you Malcom, my family might starve…thanks for all the awesome videos!
glad to hear it! Thanks for checking out the recipes!
Malcom can you do a segmant on making guacamole?
I do have a good guacamole recipe!
You did it again WOW these are awesome. I have never liked much heat until I started making your recipes so, I added just a little bit more heat.
Thanks for making the recipes printable.
I made these last night and they were unbelievably delicious! I hit the steaks with a light dusting of your AP rub right before tossing them on the grill and added some cotija cheese once the tacos were built…definitely going to make these a lot more.
You are the man! Thanks, Malcom!
Great tacos! Just follow the recipe and you’ll never go to a Mexican restaurant again!
Re-visiting this recipe with Cinco De Mayo coming up. For the salsa, I was thinking about throwing a chunk of wood on there to give the vegetables a little extra smoke flavor. What type of wood would you think works best?
I think Pecan would be good!
Hi Malcom – i’m going to make this for a bbq i’m having in a few weeks! any subs for the tequila?
Just omit it…
hi Malcom, for your flank steak tacos, how many lbs of flank would i need for 30 people? i’m going to try this recipe for the guys at work tomorrow
I would estimate around 1/3-1/2 lb per person
Does the marinade have any heat to it?
How would cook the flank steak on Traeger,that’s the only grill I have
It’s a five, just like his Boston butt pulled pork with the apricot sauce is a 5. I used to think I was pretty good will pulled pork. That was until I watched Malcom’s video. We have also done his ham. I look for what he says, before I smoke anything from now on.
