Step‑by‑Step Instructions for Grilled Flank Steak

Step 1: Prepare Marinade
In a small mixing bowl, whisk together 1/4 cup of apple cider vinegar, 1/4 cup of extra-virgin olive oil, 4 cloves of minced garlic, 2 teaspoons of kosher salt, and 2 tablespoons of brown sugar until well combined. This garlic marinade will elevate your grilled flank steak with a blend of tangy and sweet flavors.

Step 2: Marinate Steak
Season the flank steak, about 1.5 pounds, with freshly cracked black pepper and the remaining salt. Place the steak in a baking dish or a large zip-top bag, then pour the marinade over it, ensuring it’s well coated. Seal the bag or cover the dish and refrigerate for at least 1 hour, or up to 4 hours for deeper flavor penetration.

Step 3: Preheat Grill
Preheat your grill to medium-high heat, around 450°F to 500°F. This high temperature ensures a beautiful sear on the grilled flank steak while keeping it juicy inside. If using a charcoal grill, allow the coals to burn down until they are covered with white ash, ready for grilling.

Step 4: Grill Steak
Once the grill is ready, remove the steak from the marinade, letting any excess drip off. Place it on the grill and cook for about 5-8 minutes per side, flipping only once. Use an instant-read thermometer to check for an internal temperature of 135°F for medium-rare, or adjust cooking time according to your desired doneness.

Step 5: Rest and Slice
After grilling, transfer the steak to a cutting board and let it rest for 5 minutes. This resting period allows the juices to redistribute, ensuring every bite of your grilled flank steak remains tender and flavorful. Slice the steak thinly against the grain on a diagonal, maximizing tenderness, and serve it immediately.

Grilled Flank Steak Recipe FAQs

How do I choose a ripe flank steak for grilling?
Absolutely! When selecting flank steak, look for a cut that is bright red in color with a good amount of marbling—this fat will help keep the meat juicy during cooking. Avoid any steaks with dark spots, as these can indicate spoilage. If possible, always ask your butcher for the freshest cut available!

What’s the best way to store leftover grilled flank steak?
Very! To keep your grilled flank steak fresh, store it in an airtight container in the refrigerator for up to 3 days. Make sure the steak is completely cooled before sealing to maintain maximum flavor and texture. If you want to keep it longer, you can freeze it for up to 3 months!

Can I freeze grilled flank steak?
Absolutely! For freezing, wrap the cooled steak tightly in plastic wrap, followed by aluminum foil, or place it in a freezer-safe zip-top bag. This ensures the steak is protected from freezer burn. When you’re ready to enjoy it again, thaw it overnight in the fridge before reheating.

What do I do if my flank steak is tough after grilling?
Oh no! If your flank steak turns out tough, it’s often due to overcooking or not slicing against the grain. To avoid this in the future, use an instant-read thermometer to check for doneness—aim for 135°F for medium-rare! Also, always slice the steak on a diagonal against the grain for maximum tenderness. If you find yourself with leftover tough steak, thinly slicing it for use in tacos or salads is a great way to enjoy it!

Can I cook grilled flank steak for special dietary needs, like gluten-free?
Very! The grilled flank steak recipe is naturally gluten-free, as it doesn’t include any soy sauce or other gluten-containing ingredients. If you’re marinating for extra flavor, double-check any marinade ingredients for potential gluten sources. Additionally, feel free to customize the marinade to suit your dietary preferences!

How long can I marinate flank steak for the best flavor?
I recommend marinating your flank steak for at least 1 hour and up to 4 hours for optimal flavor infusion. Don’t marinate beyond 24 hours, as the acidity can break down the meat too much, making it mushy. Just be sure to keep it refrigerated while it marinates to ensure safety and freshness!
