Why We Love Grilled and Marinated Flank Steak Tacos
When it comes to grilling, there are steaks you can just slap on the grill, like Grilled Rib Eye or Sirloin, some chewy cuts that destined for kebabs, and there are those like flank steak that really benefit from a good marinade fist. This super-simple chipotle marinade helps to tenderize the beef and adds so much flavor!
To get these delicious tacos on the table all you have to do is whip up the marinade the day before and let the flank steak sit in all of the yumminess overnight to get the best flavor. Then the next day fire up your grill and cook the steak for a few minutes, then slice and serve. If you don’t have a grill, no worries, I have instructions for cooking the steak indoors too.

Ingredients For Grilled Flank Steak Tacos
NOTE: To save time, we let some of the ingredients do double duty: The marinade ingredients are also used in the coleslaw.
- Flank Steak: The star of these tacos! This is one of my favorite types of beef to grill and hands down the best steak for tacos because it has great flavor and can be sliced super thin. Thin steak is easier to bite through without the tacos falling apart.
- Maple Syrup: One of the secret ingredients in our flank steak marinade and key to balancing the spicy chiles!
- Chipotle Chiles: A superpower ingredient adds spicy flavor and smoky taste to make the steak really stand out! Look for canned chipotle in adobo in the Mexican food aisle of large supermarkets.
- Apple cider vinegar: Adds flavor to the steak and helps to tenderlize the beef. We also use a splash of vingar in the shredded cabbage coleslaw to help bring a tart and refreshing flavor into the mix.
- Salt: You’ll need salt to season the steak marinade and some will go into the slaw
- Neutral oil: For oiling the grill and to add to the dressing. I like avocado oil or canola oil because they do not add any extra flavor, but olive oil would be good too.
- Chopped cabbage: A big part of Healthy Seasonal Recipes mission is to incorporate more veggies into everyday recipes. In these steak tacos, we’ve made cabbage a key ingredient. When dressed with a vinegar dressing, it acts as a crunchy fresh and tangy element to balance the savory grilled beef.
- Radishes: Radish are a common ingredient in Mexican tacos, so I added them to the slaw. Cut them into matchsticks with a sharp chef’s knife or use a mandoline. Watermelon radish or Daikon are easy julienne cut.
- Cilantro leaves: For seasoning the slaw and to garnish the tacos
- Avocado: For topping the tacos
- Soft corn tortillas: If your family prefers flour tortillas for taco night, look for the smaller taco sized ones. You can also use hard taco shells. No matter what kind you like, just make sure they’re warmed through when the steak is ready to serve.
How To Make Grilled Steak Tacos
Now, before we get into the instructions for this recipe, if you do not have a grill, no worries! There are other options to cook your steak for these tacos. Visit our helpful tips section for broiling or using an indoor grill pan for the flank steak.
Step 1: Marinate Flank Steak
Remove 3 chipotle chilis from the can, mince and place in a small bowl. Add 1/4 cup of the maple syrup, 3 tablespoons of the cider vinegar, and 1 teaspoon salt to the bowl and whisk to combine. Place the flank steak in a large casserole dish or Ziplock bag. Pour on the marinade and turn to coat the steak. Cover (or seal the bag) and refrigerate for 12 to 24 hours.
Step 2: Preheat the grill and cook the steak.
Preheat your charcoal or gas grill to medium-high heat. Remove the flank steak from the marinade and discard any remaining marinade. Oil your grill rack and place the flank steak on the grill. Grill steak, 5 to 7 minutes per side for medium rare, 6 to 7 for medium and 8 minutes per side for medium-well. If you have a reliable digital thermometer the steak should read 135 to 145 degrees F for medium-rare to medium. Let the grilled flank steak rest 10 minutes while preparing the slaw.
Step 3: Prepare the slaw.
Whisk the remaining maple syrup, vinegar, salt and oil in a medium bowl. Add cabbage, radishes and cilantro and toss to combine.
Step 4: Slice the steak and serve.
Slice the flank steak into thin strips, across the grain. Fill tortillas with steak and slaw and top with avocado.
To broil flank steak for tacos:
- Arrange oven rack in upper third of the oven. Preheat broiler. Coat a broiler pan with cooking spray. Drain steak, pat dry with paper towels and discard marinade. Place steak on the broiler pan.
- Broil the beef just below the heat for 3 minutes. Turn the pan 180 degrees and continue cooking until the meat starts to char in areas.
- Flip meat over and cook under the heat, rotating once for an additional 4 to 6 minutes. Let meat rest for at least 5 minutes before slicing against the grain.
To cook flank steak on an indoor grill pan:
- Make sure your grill pan is wide enough to accommodate the steak. If it isn’t, you can broil it (see above) or pan-sear it in a large skillet. Preheat the grill pan over high heat and set the fume hood on high. Brush oil over the pan.
- Remove the steak from the marinade and pat it as dry as possible with clean paper towels. This will help it sear on an indoor grill.
- Then place in the pan, and cook until the steak has nice grill marks and easily releases from the pan. This takes about 4-5 minutes on the first side.
- Flip over and continue grilling until desired internal temperature (145 F for medium). Remove from the pan, and allow steak to rest on a cutting board for 5-10 minutes before slicing.
What Side Dishes Go With Steak Tacos?
- Make a Mexican Bean Salad or Mexican Corn Salad to go on the side
- While you have the grill going make grilled corn on the cob with lime butter
- Our Healthy Zucchini Casserole is made with green chilies and cilantro and would pair well with these tacos.
- If you have a few extra minutes, make a batch of this healthy cornbread to go on the side.
- Though it is not traditional our Mexican Pasta Salad is another side that always makes people happy!
- Serve them with this Mexican Coleslaw recipe and some Slow Cooker Pinto Beans for a complete Mexican feast!!
What Toppings Are Good For Flank Steak Tacos?
- Our homemade guacamole or pico de gallo are also excellent taco toppings.
- Sour cream or Mexican crema are delicious on steak tacos.
- Our Pickled Onions are wonderful inside grilled steak tacos.
- While the grill is fired up, make these grilled onions for a side or to add on to the tacos.
- Creamy cheese like Jack or Pepper Jack are excellent in tacos or a sharp crumbly cheese like Cotija can be added too
Leftovers, Storage and Reheating
- To me there is no better way to enjoy leftover steak than to make it into a steak salad: Try it by adding the leftover sliced flank steak to our Tomato Salad for a summertime treat.
- You can keep the leftover tacos, disassembled, in the refrigerator for up to four days. It is best to store the components in separate air-tight containers.
- Leftover grilled flank steak can be frozen for 2 months.
- To reheat the flank steak, cut into small pieces and warm in a small non-stick skillet with a little oil or melted butter until warmed through. Serve hot.
Variations To Try
- Once you try this marinade you’ll realize it is perfect for flank steak for other applications. It would be delicious served sliced and paired with Mango Black Bean Quinoa Salad and Kohlrabi slaw, or in steak lettuce wraps or over a big green salad.
- If your family doesn’t like spicy food, omit the chipotle chilies and use a much more mild blend of 1 teaspoon each chili powder and cumin in the marinade instead.
- If the cabbage slaw doesn’t appeal to you, use chopped tomatoes and shredded lettuce instead.
Chef Katie’s Expert Tips and FAQs
Flank steak is leaner and has an intense meaty flavor making it perfect for tacos. Skirt steak also has good flavor, but tends to more chewy and less tender than flank.
It is important to cut steak against the grain. Cutting across these fibers shortens them and makes the beef slices easier to chew. The grain is the direction that the muscle fibers run. In the case of a flank, which is long and skinny, they run the longer length of the flank (from end to end.) Cut across the flank from side to side. If you want smaller pieces of steak cut the flank lengthwise once, then crosswise into strips.
Flank steak is best cooked to medium rare and cut thinly across the grain. It is very important to let the steak rest for 10 minutes to allow the meat to relax, or all the juice will run out as you cut it. It is also important to cut the flank steak across the grain with a very sharp carving knife.
