Why Marinade Matters for Flank Steak

Flank steak is lean, which means it can be tough if not prepared properly. That’s where a good marinade comes in! The right blend of acidity, oil, and seasoning not only infuses the steak with incredible Mexican-style flavors but also helps break down tough muscle fibers, making the meat tender and juicy.

Here’s why this homemade marinade is a must-try:

Lime juice: Provides the perfect amount of acidity to tenderize the meat.

Oil: Helps the flavors penetrate deep into the steak.

Mexican spices: Cumin, chili powder, and garlic create an authentic taste.

Sweetness: A touch of honey balances the heat beautifully.

Chef’s Tip: The Secret to Extra Tender Steak

Here’s a little chef’s secret: add 2 tablespoons of pineapple juice to your marinade. The enzymes in pineapple break down the muscle fibers even more, making your steak extra tender! But be careful—if you marinate too long, it can get mushy. I recommend marinating for no more than 4 hours if you use pineapple juice.

Step-by-Step Instructions

1. Mix the Marinade

In a bowl, whisk together all the marinade ingredients. Pour it into a large zip-top bag or a shallow dish.

2. Marinate the Steak

Place the flank steak in the marinade, ensuring it is fully coated. Cover and refrigerate for at least 2 hours (or up to 12 hours for maximum flavor). If using pineapple juice, marinate for only 4 hours.

3. Cook the Steak

Grilling: Preheat your grill to high heat (about 450°F). Grill the steak for 4-5 minutes per side for medium-rare.

Pan-Searing: Heat a cast-iron pan over high heat. Sear the steak for 4 minutes per side, then let it rest.

Broiling: Preheat the broiler and cook for 4-6 minutes per side, keeping a close eye on it.

4. Rest & Slice

Let the steak rest for 5 minutes before slicing. Always slice against the grain for the most tender bites!
