Why This Recipe Works
The magic of this flank steak marinade lies in its balanced simplicity. The combination of olive oil, soy sauce, citrus, and a touch of sweetness creates a potent tenderizer and flavor enhancer. Olive oil helps to keep the steak moist during cooking, preventing it from drying out. Soy sauce provides essential umami depth and saltiness, crucial for a well-seasoned steak. Citrus juice, like lime or lemon, introduces acidity that tenderizes the muscle fibers, making the meat more yielding with every bite. The brown sugar not only adds a subtle sweetness but also aids in caramelization on the grill or under the broiler, developing a beautiful crust.
Flank steak is a lean cut that can sometimes be tough if not prepared correctly. This marinade is designed to overcome that challenge by penetrating the meat and breaking down tough connective tissues. The short marinating time of 30 minutes is sufficient to infuse flavor, while the option to marinate for up to 2 hours allows for deeper penetration and enhanced tenderness. Patting the steak dry before cooking is a critical step that promotes searing, leading to that desirable brown exterior and a mouthwatering contrast with the juicy interior. This methodical approach ensures a consistently delicious outcome.
Ingredients
| Ingredient | Quantity | Notes |
|---|---|---|
| Flank Steak | 2 lbs | Look for a steak that is about 1-1.5 inches thick for even cooking. |
| Extra-Virgin Olive Oil | 1/3 cup | Adds richness and aids in marinade adherence. |
| Reduced-Sodium Soy Sauce | 1/4 cup | Provides savory depth and salt. Use tamari for gluten-free. |
| Lime Juice | 2 Tbsp. | Freshly squeezed is best. Lemon juice is a suitable alternative. |
| Packed Light Brown Sugar | 2 Tbsp. | Adds sweetness and helps with caramelization. Coconut sugar can be used. |
| Kosher Salt | To taste | Use sparingly, as soy sauce is already salty. |
| Freshly Ground Black Pepper | To taste | Enhances the overall flavor profile. |
Step-by-Step Instructions
Prepare the Marinade
- In a large bowl, whisk together 1/3 cup extra-virgin olive oil, 1/4 cup reduced-sodium soy sauce, 2 Tbsp. lime juice, and 2 Tbsp. packed light brown sugar until well combined.
- Add the 2 lb. flank steak to the bowl and toss thoroughly to ensure it is completely coated with the marinade.
- Cover the bowl or transfer the steak and marinade to a resealable plastic bag. Marinate for at least 30 minutes at room temperature, or refrigerate for up to 2 hours for deeper flavor penetration.
Cook the Flank Steak
- Remove the flank steak from the marinade. Discard the remaining marinade.
- Pat the steak very dry with paper towels. This step is crucial for achieving a good sear.
- Season the steak lightly on all sides with kosher salt and freshly ground black pepper. Remember that the soy sauce in the marinade already adds saltiness.
- To Grill: Preheat your grill to medium-high heat (around 400-450°F or 200-230°C). Place the seasoned flank steak on the hot grill grates. Cook for approximately 5 minutes per side for medium-rare, adjusting time based on the thickness of your steak. Use an instant-read meat thermometer to check the internal temperature; aim for 130°F (54°C) for medium-rare.
- To Broil: Preheat your oven broiler to high. Arrange the steak on a baking sheet lined with foil or parchment paper. Place the sheet pan under the broiler. Cook for about 5 minutes per side for medium-rare, turning once halfway through. Adjust cooking time based on steak thickness and broiler intensity. Verify the internal temperature reaches 130°F (54°C) for medium-rare.
- Once cooked to your desired doneness, remove the flank steak from the heat. Let it rest on a clean cutting board for at least 5-10 minutes before slicing. This resting period allows the juices to redistribute throughout the meat, ensuring maximum tenderness and moisture.
- Slice the flank steak thinly against the grain for the most tender bite.
Chef Tips for Perfect Results
- Don’t Over-Marinate: While longer marination increases flavor, exceeding 2 hours for flank steak can sometimes lead to a mushy texture due to the acidity.
- Pat Dry Thoroughly: Moisture is the enemy of a good sear. Ensure the steak is completely dry after removing it from the marinade to achieve a beautiful caramelized crust.
- Invest in a Meat Thermometer: Cooking to the correct internal temperature is the most reliable way to achieve your desired doneness, rather than relying solely on time.
- Slice Against the Grain: Flank steak has a prominent grain. Slicing perpendicular to these muscle fibers shortens them, making the steak significantly more tender to eat.
- Resting is Non-Negotiable: Allowing the steak to rest post-cooking lets the juices settle back into the meat, preventing them from running out onto the cutting board.
Common Mistakes to Avoid
- Marinating Too Long: Over-marinating, especially with acidic ingredients, can break down the steak’s protein too much, resulting in a mushy or mealy texture. Fix: Limit marination to 30 minutes to 2 hours.
- Skipping the Drying Step: A wet steak will steam rather than sear on the grill or under the broiler, preventing the development of a flavorful crust. Fix: Pat the steak completely dry with paper towels before seasoning and cooking.
- Cooking to a Single Doneness: Flank steak can go from medium-rare to well-done very quickly. Fix: Use a meat thermometer to accurately gauge the internal temperature for your preferred doneness.
- Slicing With the Grain: This results in long, tough fibers that are difficult to chew. Fix: Always identify the direction of the muscle fibers and slice thinly across them.
- Not Resting the Steak: Cutting into the steak immediately after cooking releases all its precious juices, leaving the meat dry. Fix: Let the steak rest for at least 5-10 minutes before slicing.
Variations and Substitutions
| Ingredient | Substitution | Impact on Flavor |
|---|---|---|
| Lime Juice | Lemon Juice, Orange Juice (use less sugar) | Changes the citrus profile; orange will be sweeter and less acidic. |
| Soy Sauce | Tamari (for gluten-free), Coconut Aminos (for soy-free, less salty) | Tamari offers a similar umami; coconut aminos have a slightly sweeter, milder flavor. |
| Brown Sugar | Honey, Maple Syrup, Agave Nectar | Adds a different sweetness profile; honey and maple syrup add distinct notes. Adjust quantity if very sweet. |
| Olive Oil | Avocado Oil, Grapeseed Oil | Neutral oils won’t impart much flavor, maintaining the marinade’s core taste. |
Serving Suggestions and Pairings
This delicious flank steak is incredibly versatile. Serve it thinly sliced as the star of fajitas or tacos, alongside warm tortillas, salsa, and avocado.

Frequently Asked Questions
Can I use a different cut of beef with this marinade?
Yes, this flank steak marinade is also excellent for other lean, flavorful cuts like skirt steak or even London broil. For a thicker cut like top sirloin, you might need to adjust cooking times. Ensure your chosen cut is suitable for quick cooking methods like grilling or broiling.
How do I ensure my flank steak is not tough?
To prevent toughness, marinate the flank steak for no more than 2 hours, pat it completely dry before cooking, and cook it to medium-rare doneness. Crucially, always slice the cooked steak thinly against the grain. This technique shortens the muscle fibers, making each bite tender and enjoyable.
What if my flank steak is tough after cooking?
If your flank steak is tough, it likely wasn’t sliced correctly against the grain, or it was overcooked. To attempt a fix, slice it as thinly as possible across the grain and consider serving it in a dish where texture is less critical, like shredded in tacos or a stir-fry. Future attempts should focus on proper slicing and temperature monitoring.
Can I marinate the flank steak overnight?
For flank steak, it is best to avoid marinating overnight. Because flank steak is a lean and relatively thin cut, the acidity in marinades can begin to break down the meat’s proteins too much, leading to a mushy or mealy texture. Stick to a maximum of 2 hours for optimal results.
How do I serve this flank steak and what are the best accompaniments?
Serve this delicious flank steak sliced thinly against the grain. It is perfect for serving with robust sides that complement its flavor, such as grilled corn, roasted sweet potatoes, or a classic potato salad. For a lighter option, pair it with a vibrant quinoa salad or a fresh mixed greens salad.
