Grilled Cuban Flank Steak

If you love bold citrus, garlicky punch, and a tender, well-charred cut of meat, this Grilled Cuban Flank Steak is going to become a weeknight favorite. The recipe makes enough marinade for a 1 large piece of flank steak (about 3 pounds of meat), and the technique is simple: marinate, grill over high heat, rest, and slice thin across the grain. This steak turns out juicy, bright, and perfect for serving with rice, a crisp salad, or tucked into warm flatbreads with pickled onions and fresh herbs.

This version leans on classic Cuban-inspired flavors—plenty of citrus, garlic, and a touch of oregano—so the outside crisps while the center stays tender. The instructions below are laid out step-by-step to make grilling straightforward even if you’re new to working with flank steak. Read through once, gather your ingredients, and you’ll be grilling like a pro.

Why this works

Flank steak responds beautifully to bold marinades. The acids in the citrus and the enzymes in the pineapple or similar fruit help break down connective tissues, while the salt and oil help distribute flavor and promote a good sear. Grilling on high heat creates a caramelized crust that balances the bright marinade. Resting the steak is key—cutting it too soon lets all the juices run out. Slice thinly across the grain for tender bites every time.

Ingredients (makes enough marinade for 3 pounds of meat)

• 1 large piece of flank steak (about 3 pounds)
• 1/2 cup fresh orange juice
• 1/2 cup fresh lime juice
• 1/4 cup fresh lemon juice
• 1/4 cup olive oil
• 1/2 cup chopped cilantro
• 1/4 cup chopped parsley
• 8 cloves garlic, minced
• 2 teaspoons ground cumin
• 2 teaspoons dried oregano
• 1 teaspoon black pepper
• 2 teaspoons kosher salt
• 1/4 cup white vinegar
• 1/4 cup low-sodium soy sauce alternative (use a soy-free tamari if needed for dietary preferences)
• 1 teaspoon red pepper flakes (optional, for heat)

Equipment

• Large resealable plastic bag or nonreactive dish for marinating
• Sharp chef’s knife and cutting board
• Grill (gas or charcoal) or a very hot cast-iron pan
• Instant-read thermometer
• Foil or a plate for resting the steak

Prep and timing

Active time: about 20 minutes. Marinating time: 2–8 hours (overnight is best). Grill time: 10–14 minutes total for medium-rare to medium depending on your grill and steak thickness. Resting time: 10 minutes. Total time depends on marination but plan for overnight if you can.

Step-by-step directions

1. Make the marinade: In a medium bowl, combine 1/2 cup fresh orange juice, 1/2 cup fresh lime juice, 1/4 cup fresh lemon juice, 1/4 cup olive oil, 1/4 cup white vinegar, and 1/4 cup low-sodium soy sauce alternative. Whisk in 8 cloves garlic (minced), 1/2 cup chopped cilantro, 1/4 cup chopped parsley, 2 teaspoons ground cumin, 2 teaspoons dried oregano, 1 teaspoon black pepper, 2 teaspoons kosher salt, and 1 teaspoon red pepper flakes if using. Stir thoroughly so the salt dissolves and the herbs and spices are evenly distributed.
2. Prepare the steak for marinating: Pat the 1 large piece of flank steak dry with paper towels. Trim any excessive silver skin or thick fat if present, but keep a thin layer for flavor. Place the steak into a large resealable plastic bag or a nonreactive shallow dish that will hold the marinade without overflowing.
3. Combine steak and marinade: Pour the marinade over the steak, ensuring the liquid covers as much surface as possible. If using a bag, press out excess air and seal it. Turn the bag so the marinade coats the steak evenly. If using a dish, cover tightly with plastic wrap.
4. Marinate: Refrigerate the steak for at least 2 hours and up to 8 hours. For best flavor development, marinate overnight. If marinating longer than 8 hours, flip the steak occasionally so the marinade continues to coat it evenly. Remove the steak from the refrigerator 30 minutes before grilling to bring it closer to room temperature—this promotes even cooking.
5. Preheat the grill: Preheat your grill to high heat (about 450–500°F / 232–260°C). If using charcoal, set it up for direct high heat. Clean and oil the grates so the steak doesn’t stick.
6. Remove excess marinade: Take the steak out of the marinade and let any excess drip off. Discard the leftover marinade. Pat the steak lightly with paper towels to remove excess wetness; this helps the surface brown rather than steam.
7. Grill the steak: Place the flank steak across the hottest part of the grill. Grill undisturbed for approximately 4–6 minutes to develop a strong sear. Flip once and grill for another 4–6 minutes for a medium-rare to medium result; grill a minute or two longer per side if you prefer it more well done. Use an instant-read thermometer to check doneness: 125–130°F for medium-rare, 135°F for medium.
8. Rest the steak: Transfer the cooked steak to a cutting board and tent loosely with foil. Let it rest for 8–10 minutes. Resting locks in juices and makes slicing easier.
9. Slice thinly across the grain: Identify the direction of the muscle fibers (the grain) and slice the steak thinly across those fibers at about a 45-degree angle. Thin slices give a tender mouthfeel. Arrange the slices on a platter and spoon any juices on top.
10. Serve suggestions: Serve the steak with warm rice, grilled vegetables, or in flatbreads with quick-pickled red onions, chopped cilantro, and a squeeze of fresh lime. Leftovers are fantastic chopped into salads, tacos, or sandwiches.

Troubleshooting and tips

• Marinade balance: The marinade has a lot of citrus which both flavors and tenderizes. If your steak tastes overly acidic, reduce marinating time on your next cook or add a splash more oil to mellow it.
• Don’t skip the rest: Resting keeps juices in the meat; cutting immediately makes the steak dryer and chewier.
• Thin slices matter: Flank steak is a lean, long-grain cut. Slicing thin across the grain is the single most important step for tenderness.
• High heat sear: Make sure your grill or pan is very hot before the steak goes on. A good sear adds texture and flavor.
• Adjust heat level: Red pepper flakes are optional; omit them if you prefer no heat.
• Make-ahead: The marinade is safe to make a day ahead—store it refrigerated and then combine with the steak when ready to marinate.

Serving ideas

This Grilled Cuban Flank Steak shines with simple, fresh sides. Here are a few pairings that work beautifully:

• Steamed white or brown rice with a few sprigs of cilantro.
• Black beans simmered with onion and garlic.
• Grilled corn brushed with lime and a bit of olive oil.
• Quick-pickled red onions for brightness—slice onions thin, toss with vinegar and a pinch of salt, and let sit 15 minutes.
• Warm flatbreads or soft rolls to assemble steak sandwiches with sliced avocado and a drizzle of extra marinade reduced on the stove into a glaze.

Make it a meal

For an easy dinner, serve the steak over a bed of coconut-lime rice with a side of charred vegetables. For a casual party, set out sliced steak with bowls of chopped tomatoes, sliced cucumbers, shredded lettuce, warm tortillas, and a simple yogurt-cucumber sauce so guests can build their own wraps. The bright, citrusy flavor is a great contrast to creamy or smoky sides.

Storage

Refrigerate leftover sliced steak in an airtight container for up to 3–4 days. Reheat gently in a skillet over low heat with a splash of water or broth to keep it moist, or enjoy cold in salads and sandwiches. For longer storage, freeze portions in a freezer-safe bag for up to 3 months. Thaw overnight in the refrigerator before reheating.

Notes on ingredient swaps

• If you prefer a slightly sweeter profile, add 1 tablespoon of brown sugar to the marinade and whisk until dissolved.
• For a soy-free alternative, choose a tamari labeled for your dietary needs. Keep the quantity the same (1/4 cup).
• If fresh citrus is unavailable, bottled juices can work in a pinch, but fresh juice delivers a brighter, fresher flavor.
• Fresh herbs give the best flavor, but you can substitute with 3 tablespoons of dried combined, though the bright herbaceous pop will be reduced.

Final thoughts

When done right, this Grilled Cuban Flank Steak is vibrant, juicy, and full of character. The marinade infuses every bite with citrus, garlic, and herb notes while the high-heat grill makes the outside caramelize perfectly. Whether you’re entertaining or simply craving a flavorful weeknight dinner, this steak delivers big flavor with minimal fuss. Remember to slice thinly across the grain and let the meat rest—those two steps will make all the difference.

Happy grilling, and enjoy your Grilled Cuban Flank Steak!
