The flat iron steak is the star here. Look for dry-aged or prime at Whole Foods or your local butcher. I prefer dry-aged for that nutty, beefy flavor, but prime works too. Make sure it’s at room temperature before grilling. Let it sit out for 30 minutes before cooking.

No fresh rosemary? Dried rosemary works at one-third the amount. For the Worcestershire sauce, check the ingredients if you’re watching your sugar intake. Some brands have added sugar. You can also make your own if you’re feeling fancy. For a different twist, try substituting balsamic vinegar for the Worcestershire sauce.

This steak reheats beautifully in a 250°F oven. Store leftovers in an airtight container for up to 3 days. If you’re meal prepping, slice it thin against the grain after it rests, then portion into containers. The marinade can be made a day ahead and stored in the fridge.

Step-by-Step Instructions for BBQ Flat Iron Steak

Here’s the method that’ll get you tender, flavorful grilled perfection every time.

Step 1: Prepare the Marinade

In a blender or food processor, combine the 4 cloves garlic cloves, 2 tbsp fresh rosemary, 1 tbsp fresh thyme, 1 tsp salt, 0.5 tsp black pepper, 0.5 tsp paprika, 1 tbsp brown sugar, 2 tbsp Worcestershire sauce, and 2 tbsp lemon juice. Blend until you get a smooth, fragrant paste. I like to taste it at this stage and adjust seasoning if needed.

Place the 1.5 lb flat iron steak in a large zip-top plastic bag or a non-reactive container. Pour the marinade over the steak, turning to coat evenly. Seal the bag or cover the container, then refrigerate for at least 2 hours or overnight (up to 12 hours). The longer it marinates, the more tender and flavorful it’ll become.

Step 2: Preheat Grill and Prepare Steak

Preheat your grill to medium-high heat (around 400°F). While the grill is heating up, remove the steak from the marinade, letting any excess drip off. Pat the steak dry with paper towels to promote even browning. Brush both sides with 0.25 cup olive oil to prevent sticking and enhance flavor.

Season the steak with additional salt and pepper if desired. I like to keep it simple and let the marinade do the work, but a bit more seasoning never hurts. Make sure your grill grates are clean and brush them with oil to prevent sticking.

Step 3: Grill to Perfection

Place the steak on the preheated grill and sear for 4-5 minutes per side for medium-rare, or until it reaches your desired level of doneness. For medium, cook for 5-6 minutes per side. Use tongs to flip the steak, as they won’t pierce the meat like a fork would. Let it rest for 5 minutes after cooking.

To check for doneness, use an instant-read thermometer inserted into the thickest part of the steak. For medium-rare, it should read 130-135°F. The internal temperature will rise a few degrees during resting, so take it off the heat when it’s just below your target temperature.

Step 4: Rest and Slice

Transfer the steak to a cutting board and tent it loosely with foil. Let it rest for 5-10 minutes to allow the juices to redistribute throughout the meat. This step is crucial for achieving that tender, juicy texture we all love.

Slice the steak against the grain into thin strips. You’ll notice the difference in tenderness when you cut against the grain. Serve immediately, garnished with additional fresh herbs if desired. Your perfectly grilled flat iron steak is now ready to enjoy!

Regional Styles of This Dish

Texas Style BBQ

In Texas, flat iron steak gets the full dry rub treatment with a mix of chili powder, cumin, and black pepper. The steak is cooked low and slow over post oak or mesquite, giving it that authentic Texas flavor. I love how this style brings out the rich beefy taste. 🔥

Carolina Style

In the Carolinas, they might give flat iron steak a vinegar-based mop sauce during cooking, adding a tangy kick. This style pairs beautifully with the rich flavor of the steak. You can try using a mixture of apple cider vinegar and water for a similar effect. The acidity helps tenderize the meat.

Kansas City Style

Kansas City pitmasters love to use a thick tomato-based BBQ sauce on their flat iron steaks. The sauce caramelizes on the grill, creating a sweet and sticky crust. I recommend using a good quality Kansas City-style BBQ sauce for this. The sweetness balances out the savory flavor of the steak.

Memphis Style

Memphis-style BBQ often features a dry rub with a blend of spices, including paprika, garlic powder, and onion powder. The steak is then slow-cooked over charcoal or wood, giving it a rich, smoky flavor. This style is all about the meat, so keep the sauce to a minimum. 🌟

Alabama Style

In Alabama, they might use a white BBQ sauce made with mayonnaise, vinegar, and spices. This creamy sauce adds a unique twist to the traditional BBQ flavors. It’s a great way to mix things up and try something new. The tangy flavor pairs well with the grilled steak.
