Flank steak tacos with perfectly seared, medium-rare beef topped with an irresistibly tangy pico verde. Serve on charred corn tortillas with at least one beer or margarita!
Which means it doesn’t need to be grilling weather either! So. Much. Winning.
All you need is a big cast iron skillet and a good meat thermometer. This cut of meat cooks up quick so the thermometer is key. Overcooked flank steak tends to be tough. You’ll want to remove it from your skillet at 130°F because it will continue to cook while it’s resting.
Also, get the biggest skillet you can find. Because you can never have enough perfectly seared flank steak in the house.
I love Mexican food. And utterly adore tacos. Your standard-issue ground beef tacos have been a favorite in this house since forever. So, please, don’t take this as a dig at the classic, O G taco when I say these flank steak tacos, especially with this uniquely delicious pico verde, are simply in a league all their own.
There are three elements to this recipe that make these tacos stand out from the crowd.
The beef is marinated in…basically…a margarita. So all those things you love about a good margarita? The tang of the limes mingled with the salty rim. Triple sec’s sweet citrusy notes harmonizing with señor tequila’s bawdy, agave-laced melody. It’s all in the steak. Plus, it’s STEAK!
This pico verde is not merely pico de gallo made with tomatillos instead of red tomatoes. It’s so much better than that, mamasita. There are also cucumbers, scallions, and even capers in there! Not to mention fresh herbs. Tangy, crispy and oh-so-fresh the pico really brings these tacos to life. The key to success here is dicing all the ingredients to pretty much the same size.
The Charred Corn Tortillas
Just lay a tortilla over the burner on your stove and let the flame flirt with it. You need to chaperone them though because left too long to their own devices things tend to…ignite. It’s not just about the char flavor this brings to the table, although that’s reason enough to do it. But it also slightly changes the texture of the tortilla. Puffing it up a bit and making it a little less dense.
And there you go. This recipe feeds a crowd so don’t hesitate to invite the troops over and dazzle them with your taco skillz! Any leftover flank steak will be great in a salad or between two slices of good bread. Leftover pico verde is insane on eggs.

Place steak in a large ziploc bag and pour marinade into it. Seal bag and massage marinade around the meat to coat it.
Let marinate in the refrigerator for 4 hours up to overnight.
Combine all pico ingredients in serving bowl. Taste and salt, if necessary. You may find the capers make it salty enough.

In a large cast-iron skillet over medium-high flame, melt about one Tablespoon of ghee (or your preferred fat.)
Remove steak from marinade and pat dry with a clean paper towel.
Place in skillet and brown on one side, about 4 to 5 minutes. Then flip it and insert meat thermometer in the thickest part of the meat.

- Calorie info is approximate and will vary with some ingredients and exact serving size.
- Marination time is not included in timing of this recipe.
- Sometimes, with a particularly thick steak, I'll flip it back onto its original side before it's cooked through so it cooks evenly on both sides.
