Flank Steak Tacos With Charred Corn Salsa: A Fiesta in Every Bite

The aroma of sizzling steak, the smoky char of grilled corn, the bright tang of lime… these scents instantly transport me back to my summers spent in San Diego. My abuela, a culinary genius in her own right, would whip up these flank steak tacos for our family gatherings. The secret was always the charred corn salsa – sweet, spicy, and utterly addictive. Every bite was a burst of sunshine, laughter, and the love that only family and great food can bring. This recipe is my humble attempt to recreate that magic.

Recipe Overview

Prep Time: 20 minutes
Cook Time: 20 minutes
Total Time: 40 minutes
Servings: 4
Yield: 12 tacos
Dietary Type: Gluten-Free (if using corn tortillas)

Ingredients

1 teaspoon ground cumin
Salt and pepper
1 (1 1/2 lb) flank steak, trimmed of fat
2 tablespoons vegetable oil
1 1⁄2 cups fresh corn or 1 1/2 cups thawed frozen corn
1⁄4 cup finely chopped red onion (if pinched use yellow)
1 jalapeno chili, stemmed seeded and minced
2 tablespoons lime juice
1 tablespoon minced fresh cilantro
12 (6 inch) corn tortillas, warmed

Equipment Needed

12-inch cast-iron skillet
Medium bowl
Small bowl
Cutting board
Sharp knife
Potholders

Instructions

Adjust the oven rack to the middle position, place a 12-inch cast-iron skillet on the rack, and heat the oven to 500°F. It’s crucial to get the skillet screaming hot for a proper sear.
While the oven is preheating, prepare the spice mixture. In a small bowl, combine 1 teaspoon of ground cumin, 3/4 teaspoon of salt, and 1/2 teaspoon of pepper. Mix well.
Prepare the flank steak. Cut the steak lengthwise with the grain into 2 equal pieces. Then, cut each piece in half crosswise to create four equal pieces. This makes it easier to manage the steak in the hot skillet. Season the steaks generously with the prepared spice mixture, ensuring each piece is evenly coated. Let the seasoned steaks sit at room temperature while the oven preheats – this allows the spices to meld with the meat and helps the steak cook more evenly.
Once the oven reaches 500°F, carefully pat the steaks dry with paper towels. This step is essential for achieving a good sear, as excess moisture will steam the steak instead of browning it.
Using potholders (the skillet will be incredibly hot!), remove the skillet from the oven and place it over medium-high heat on the stovetop. Turn off the oven.
Being cautious of the hot skillet handle, add 2 tablespoons of vegetable oil to the skillet and heat until it just begins to smoke. The smoking oil indicates it’s hot enough to create that beautiful crust on the steak.
Carefully add the steaks to the hot skillet, ensuring they aren’t overcrowded. Cook the steaks, without moving them, until they are lightly browned on the first side, about 2 minutes. Resist the urge to peek or move them around, as this will interfere with the searing process.
Flip the steaks and continue to cook until lightly browned on the second side, about 2 minutes. Again, maintain a hands-off approach to achieve even browning.
Flip the steaks again, reduce the heat to medium-low, and continue to cook, flipping every 2 minutes, until the steaks are well browned and a meat thermometer registers 120°F to 125°F (for medium-rare), which should take approximately 4 to 8 minutes. Remember that the internal temperature will continue to rise slightly as the steak rests.
Transfer the steaks to a carving board, tent them loosely with aluminum foil, and let them rest while you prepare the salsa. This resting period is crucial for allowing the juices to redistribute throughout the meat, resulting in a more tender and flavorful steak.
Without cleaning the skillet (those flavorful browned bits will add depth to the salsa), add 1 1/2 cups of fresh corn (or thawed frozen corn) to the now-empty skillet. Cook over medium heat, without stirring, until the corn is lightly charred, about 4 minutes.
Stir the corn and continue to cook until tender, about 1 minute. Transfer the charred corn to a medium bowl.
To the bowl with the charred corn, add 1⁄4 cup of finely chopped red onion, 1 jalapeno chili (stemmed, seeded, and minced), 2 tablespoons of lime juice, 1 tablespoon of minced fresh cilantro, 1/4 teaspoon of salt, and 1/4 teaspoon of pepper. Stir well to combine. Season with additional salt and pepper to taste. Adjust the lime juice and jalapeno to your preferred level of tanginess and heat.
Slice the rested flank steak thinly against the grain. This is essential for ensuring the steak is tender and easy to chew.
Warm 12 (6-inch) corn tortillas. You can warm them in a dry skillet, in the microwave wrapped in a damp paper towel, or over an open flame for a slightly charred effect.
Serve the sliced flank steak in the warmed corn tortillas topped generously with the charred corn salsa.

Expert Tips & Tricks

Spice it up (or down): Adjust the amount of jalapeno in the salsa to your preferred heat level. For a milder salsa, remove the seeds and membranes from the jalapeno completely. For extra heat, leave some of the seeds in.
Don’t skip the rest: Resting the steak is essential for a juicy and tender final product.
Get a good sear: Patting the steak dry and using a very hot skillet are crucial for achieving a beautiful crust.
Charred perfection: Don’t be afraid to let the corn get nicely charred in the skillet. The charred flavor adds a wonderful depth to the salsa.
Warm tortillas are key: Cold tortillas will make your tacos less enjoyable. Warm them up for a few seconds on each side in a hot pan.
Make ahead magic: The corn salsa can be made a day in advance. Store it in the refrigerator and the flavors will meld together beautifully.

Serving & Storage Suggestions

Serve the flank steak tacos immediately after assembling to enjoy the best flavor and texture. Garnish with extra cilantro or a dollop of sour cream if desired.

Leftover steak can be stored in an airtight container in the refrigerator for up to 3 days. The corn salsa can also be stored in an airtight container in the refrigerator for up to 3 days.

To reheat the steak, warm it gently in a skillet over medium-low heat or in the microwave in short intervals to prevent it from drying out. Reheat the tortillas separately.

FAQs (Frequently Asked Questions)

Q: Can I use a different cut of steak?
A: While flank steak is ideal for its tenderness and quick cooking time, skirt steak or even sirloin can be used as a substitute. Just adjust the cooking time accordingly.

Q: Can I use frozen corn for the salsa?
A: Yes, frozen corn works perfectly well. Just make sure to thaw it completely and pat it dry before adding it to the skillet.

Q: How do I prevent the tortillas from tearing when I fill them?
A: Make sure the tortillas are warmed properly. This makes them more pliable and less likely to tear. You can also lightly steam them to make them even softer.

Q: Can I make the steak ahead of time?
A: Yes, you can cook the steak ahead of time and store it in the refrigerator. However, it’s best to slice it just before serving to prevent it from drying out.

Q: What other toppings would be good with these tacos?
A: Shredded lettuce, diced tomatoes, guacamole, and pickled onions are all great additions to these tacos.
