Grilled Flank Steak with Marinade

I first made grilled flank steak with marinade on a summer evening when I wanted something bold and juicy for a backyard cookout so I whisked together a quick blend of lime juice, garlic, and soy sauce, let the steak soak up the flavors, and tossed it on the grill. The sizzle and char marks were beautiful but the real magic happened when we sliced into it and the flavor burst through with every bite.

What I love about this grilled flank steak is how the marinade transforms a simple cut of meat into something incredibly tender and flavorful. It’s one of those dishes that feels impressive but is easy to prep ahead and perfect for anything from a casual family dinner to a weekend gathering.

Ingredients

• Here’s what I use for this recipe. You can always make substitutions if you prefer!
• Flank steak – A lean and flavorful cut that’s perfect for marinating and grilling.
• Soy sauce – Adds saltiness and umami depth to the marinade.
• Olive oil – Helps carry the flavors into the meat and promotes browning.
• Lime juice – Brightens the marinade and tenderizes the steak.
• Garlic – Gives the marinade a bold aromatic base.
• Brown sugar – Adds a touch of sweetness and helps the steak caramelize on the grill.
• Black pepper – Adds a bit of heat and balance.
• Green onions – Fresh and mild garnish that finishes the dish with color and flavor.

Tools You’ll Need

• Mixing bowl – To whisk together the marinade ingredients.
• Resealable plastic bag or dish – For marinating the steak evenly.
• Grill or grill pan – To get those beautiful sear marks and smoky flavor.
• Tongs – For flipping the steak without piercing it.
• Meat thermometer – To check for your preferred doneness.
• Cutting board and knife – To rest and slice the steak thinly across the grain.

Instructions

Step 1:

I start by whisking together the soy sauce, olive oil, lime juice, minced garlic, brown sugar, and black pepper in a bowl until well combined.

Step 2:

I place the flank steak in a large resealable bag or shallow dish then I pour the marinade over it and refrigerate it for at least 2 hours or overnight for deeper flavor.

Step 3:

When I’m ready to cook I preheat the grill to medium-high heat and remove the steak from the marinade letting any excess drip off.

Step 4:

I grill the steak for about 4–6 minutes per side depending on thickness until it reaches my desired doneness then I transfer it to a cutting board and let it rest for 5–10 minutes.

Step 5:

I slice the steak thinly against the grain to ensure maximum tenderness and sprinkle it with chopped green onions for a fresh finishing touch.

Tips

If you don’t have lime juice you can substitute lemon juice or even a splash of vinegar. I sometimes add a pinch of crushed red pepper to the marinade for a spicy kick. Always slice flank steak across the grain—it makes a huge difference in tenderness. And don’t skip the resting step—it helps keep all those delicious juices in the meat!

Ways to Serve

Grilled flank steak is perfect with a side of roasted veggies, rice, or grilled corn. I also love slicing it and adding it to tacos, salads, or even sandwiches for a flavorful upgrade. Leftovers make amazing steak wraps or protein-packed bowls the next day!

Frequently Asked Questions

How long should I marinate flank steak?

At least 2 hours is great, but overnight gives you the most flavor and tenderness.

Can I use another cut of beef for this marinade?

Yes! Skirt steak or flat iron are also great choices and respond well to marinating.

What temperature should flank steak be cooked to?

I prefer medium-rare at 130–135°F for the juiciest result but you can go up to 145°F for medium.
