Ingredients

This marinade is a testament to the power of simple, high-quality ingredients working in harmony. Its beauty lies in its ability to penetrate the flank steak, infusing it with incredible flavor and ensuring a tender, juicy outcome.

• 1/2 cup Tamari: This is our salty, umami-rich base. Tamari, being a wheat-free soy sauce, offers a deeper, more nuanced flavor and is a fantastic choice for those avoiding gluten.
• 1/2 cup Water: To help dilute the intensity of the tamari and vinegar, creating a balanced marinade.
• 1/2 cup Vinegar: The acidity here is crucial for tenderizing the flank steak. While the original recipe notes “whatever you have on hand,” rice wine vinegar is an excellent choice for its mild flavor. Apple cider vinegar or white wine vinegar would also work beautifully.
• 1/4 cup Lemon Juice: The bright, fresh citrus notes from lemon juice add another layer of acidity and a lovely counterpoint to the savory elements. Freshly squeezed is always best!
• 1 teaspoon Dried Parsley Flakes: For a subtle herbaceous note and a touch of color.
• 1 teaspoon Dry Mustard: This adds a gentle warmth and complexity without being overpowering. It’s a subtle but impactful ingredient in this blend.
• 1 Garlic Clove, minced: Freshly minced garlic provides an essential aromatic foundation that complements the other ingredients perfectly.

Equipment Needed

While this marinade requires minimal equipment, having the right tools makes the process smooth and efficient.

• Medium Bowl: For combining all the marinade ingredients.
• Whisk: To thoroughly combine the ingredients and ensure a smooth emulsion.
• Airtight Container or Resealable Bag: For marinating the flank steak.

Instructions

The preparation of this marinade is wonderfully straightforward, allowing more time for the flavors to work their magic on the steak.

1. In a medium bowl, combine the tamari, water, vinegar, lemon juice, dried parsley flakes, dry mustard, and minced garlic clove.
2. Whisk vigorously until all ingredients are well combined and the mustard is fully incorporated. This ensures an even distribution of flavor.
3. Place your flank steak into an airtight container or a large resealable bag.
4. Pour the prepared marinade over the flank steak, ensuring the steak is fully coated. Massage the marinade into the meat if using a bag.
5. Refrigerate the marinating flank steak for a minimum of 4 hours. For an even deeper flavor penetration and more tender results, marinate overnight.

Expert Tips & Tricks

To truly elevate your flank steak experience, consider these professional insights:

• Don’t Skimp on Marinating Time: Flank steak is a leaner cut with a somewhat dense grain. The longer it marinates, the more tender and flavorful it will become. Overnight is truly ideal.
• Pat it Dry: Before cooking, pat the flank steak thoroughly dry with paper towels. This is a critical step for achieving a beautiful, caramelized sear on the exterior. Excess moisture will steam the steak rather than sear it.
• Grilling Perfection: Flank steak is fantastic on the grill. Aim for a high heat to get those lovely grill marks and a quick sear. For medium-rare, grill for about 4-6 minutes per side, depending on thickness.
• Pan-Searing Powerhouse: You can also achieve excellent results on the stovetop. Heat a heavy-bottomed skillet (cast iron is ideal) over medium-high heat with a tablespoon of high-smoke-point oil like avocado or grapeseed oil. Sear for 3-5 minutes per side for medium-rare.
• Rest is Best: After cooking, always let your flank steak rest for at least 5-10 minutes before slicing. This allows the juices to redistribute throughout the meat, resulting in a more tender and moist steak.
• Slice Against the Grain: This is perhaps the most important tip for flank steak. Identify the direction of the muscle fibers (the grain) and slice the steak thinly against it. This shortens the fibers, making the steak incredibly tender to eat.

Serving & Storage Suggestions

This marinated flank steak is incredibly versatile. It’s a star on its own, but it also shines in other applications.

• Serving: Slice the rested steak thinly against the grain and serve immediately. It pairs beautifully with roasted vegetables, a fresh salad, or your favorite grains. For a more casual meal, consider slicing it for fajitas or tacos.
• Storage: Leftover cooked flank steak can be stored in an airtight container in the refrigerator for 3-4 days. It can also be frozen for up to 2-3 months. To reheat, gently warm it in a skillet over low heat or in the oven. Be mindful not to overcook it, as it can become tough.

Variations & Substitutions

While this marinade is fantastic as is, feel free to experiment with its components:

• Vinegar Swap: As mentioned, feel free to use apple cider vinegar, white wine vinegar, or even a red wine vinegar for a slightly different acidic profile.
• Citrus Twist: A splash of lime juice can be used in place of or in addition to the lemon juice for a more tropical flair.
• Herbal Notes: While parsley is classic, dried oregano or a pinch of thyme can add another dimension to the herb profile.
• Spice it Up: If you’re not avoiding pepper, a pinch of freshly ground black pepper can add a subtle warmth. For a more pronounced heat, consider adding a pinch of red pepper flakes.

FAQs

Q: Can I use this marinade for other cuts of beef?
A: Absolutely! While it’s particularly well-suited for flank steak, this marinade is also excellent for skirt steak, sirloin, or even chicken.

Q: How do I know if my flank steak is done?
A: The best way to check for doneness is with an instant-read meat thermometer. For medium-rare, aim for an internal temperature of 130-135°F (54-57°C).

Q: Is it okay to leave the marinade ingredients in the bowl with the steak when cooking?
A: No, it’s generally not recommended to cook the steak in the marinade, especially if you’re not grilling. For pan-searing, discard the marinade before cooking. If grilling, you can baste the steak with some of the marinade as it cooks, but ensure it boils vigorously to kill any bacteria.

Q: Why is it important to slice flank steak against the grain?
A: Flank steak has long, prominent muscle fibers. Slicing against these fibers shortens them, making the meat significantly more tender and easier to chew.

Q: Can I make this marinade ahead of time?
A: Yes, the marinade can be prepared and stored in an airtight container in the refrigerator for up to 3-4 days before you plan to use it.
