BBQ Skirt Steak Recipe Grill: Smoky Char with Juicy Slices

Skirt steak on the grill delivers unmatched flavor with its bold beefy character and open grain structure that soaks up marinades beautifully. This cut responds perfectly to high heat, developing a deep char while maintaining juicy tenderness inside.

The key is proper preparation: a dry brine enhances natural flavors, while a simple oil-based marinade prevents sticking. High heat sears quickly, creating that prized smoky crust without overcooking the lean meat.

You’ll achieve perfectly medium-rare slices with defined grill marks and a texture that’s tender yet substantial. The smoky aroma alone makes this worth firing up the grill for.

Serve with chimichurri or grilled vegetables to complete the meal. This method works every time.

Ingredients for Bbq Skirt Steak Recipe Grill

Bold beefy flavor starts with quality skirt steak and a dry brine for maximum juiciness.

The skirt steak is non-negotiable here. Inside cut has slightly better texture than outside, but either works. Look for vibrant red color with good marbling at Whole Foods or Costco. Ask the butcher to trim excess fat if it’s over 1/4-inch thick. For the dry brine, Diamond Crystal kosher salt dissolves fastest—morton takes longer but works fine.

No fresh herbs? Dried rosemary and thyme at one-third the amount (that’s about 2 tsp each). The Worcestershire can be swapped for soy sauce or tamari if needed. Out of lime? Lemon works in a pinch, but the zest loses some of that signature brightness. The honey can be brown sugar dissolved in warm water for a similar effect.

Marinated steak keeps 24-48 hours in the fridge (any longer and it starts to break down). Bring to room temperature before grilling—about 30 minutes on the counter. Leftover cooked steak? Slice thin, store in airtight container for up to 4 days.

Step-by-Step Instructions for Grilled Skirt Steak

Master the technique for achieving smoky char and tender slices with these precise steps.

Step 1: Dry Brine and Season the Skirt Steak

Pat the 2 lb Skirt Steak completely dry with paper towels—this ensures proper browning. Season generously on both sides with the 2 tbsp Kosher Salt and 1 tbsp Black Pepper, pressing the seasoning into the meat so it adheres.

Place the steak on a wire rack set over a plate and refrigerate uncovered for 1 hour. This dry brine draws moisture to the surface, where the salt dissolves and reabsorbs, seasoning the meat deeply and enhancing juiciness.

Step 2: Prepare the Marinade and Coat the Steak

In a bowl, whisk together the 0.25 cup Olive Oil, 4 cloves Garlic Cloves (minced), 2 tbsp Fresh Rosemary (chopped), 2 tbsp Fresh Thyme (leaves only), 2 tbsp Red Wine Vinegar, 1 tbsp Worcestershire Sauce, 1 tbsp Lime Zest, 2 tbsp Lime Juice, and 1 tbsp Honey until fully emulsified.

Transfer the skirt steak to a resealable bag or shallow dish and pour the marinade over it, turning to coat evenly. Marinate at room temperature for 30 minutes, flipping once. This short marinade tenderizes the meat without breaking down its structure, preserving texture.

Step 3: Grill Over High Heat for Optimal Char

Preheat your grill to high heat (about 450-500°F). Remove the steak from the marinade, letting excess drip off, and place it on the grill grates. Sear undisturbed for 3-4 minutes until deep grill marks form and the steak releases easily from the grates.

Flip and cook for another 3-4 minutes for medium-rare, or until the internal temperature reaches 130-135°F. Avoid pressing the steak with your tongs—this squeezes out precious juices. If flare-ups occur, move the steak to a cooler part of the grill temporarily.

Step 4: Rest and Slice Against the Grain

Transfer the steak to a cutting board and tent loosely with foil. Let it rest for 10 minutes—this allows the juices to redistribute, ensuring every slice is moist and flavorful. Thinly slice the 1 whole Red Onion and arrange it on a serving platter.

Slice the skirt steak against the grain into ¼-inch thick strips. The grain runs lengthwise along the steak, so cut perpendicular to those lines. This shortens the muscle fibers, making each bite tender. Arrange the slices over the red onion and serve immediately while hot.

Pro Cooking Tips for Perfect Results

Grill Temperature Control

Preheat your grill to 450-500°F and maintain that heat throughout cooking. I test with a ThermoWorks Instant Read—David swears by it. Clean grates prevent sticking and ensure perfect char marks. 🌡️

Searing Technique

Place steak on the hottest part of the grill and resist the urge to move it. Let it sear undisturbed for 3-4 minutes until deep grill marks form. This creates the Maillard reaction that gives that smoky crust we all love.

Avoiding Flare-Ups

Trim excess fat to ¼-inch to minimize flare-ups. If flames appear, move the steak to a cooler zone temporarily. Keep a spray bottle of water nearby for emergencies, but use sparingly.

Resting is Crucial

Always rest your steak for 10 minutes before slicing. I learned this the hard way at Nana Mae’s diner—cutting too soon sends all those beautiful juices straight to the cutting board. Tent loosely with foil to keep it warm. 💡

Slicing Against the Grain

Skirt steak grain runs lengthwise. Cut perpendicular to those lines in ¼-inch slices. This shortens muscle fibers for maximum tenderness. I use a Wüsthof 8-inch chef’s knife for clean cuts.

Testing Doneness

Use an instant-read thermometer for accuracy. Pull at 130-135°F for perfect medium-rare. The steak will continue cooking as it rests, reaching ideal 145°F internal temperature.
