For the best flank steak, look for uniform thickness—this ensures even cooking. Most grocery stores carry it in the premium meat section. If you can’t find flank steak, skirt steak or flat iron are good alternatives. For the marinade, low-sodium soy sauce helps control salt levels while maintaining umami flavor.

No smoked paprika? Use regular paprika with a dash of liquid smoke. The apple cider vinegar adds brightness—white wine vinegar or rice vinegar work as substitutes. For the BBQ sauce, choose a quality brand with a good balance of sweet and tangy. If you prefer homemade, mix ketchup, brown sugar, and apple cider vinegar for a quick alternative.

This dish stores well—3-4 days in the fridge. Reheat gently in the oven with a bit of extra BBQ sauce to keep it moist. You can also slice it thin for 3 months in the freezer.

Step-by-Step Instructions for BBQ Flank Steak in the Oven

Here’s the method that delivers tender, flavorful BBQ flank steak every time.

🔥 Step 1: Marinate the Flank Steak

In a large bowl, whisk together 0.5 cup Soy Sauce, 0.25 cup Brown Sugar, 2 tbsp Apple Cider Vinegar, 1 tbsp Dijon Mustard, 1 tsp Smoked Paprika, 1 tsp Black Pepper, and 0.5 tsp Kosher Salt until the sugar dissolves. Add 4 cloves minced Garlic Cloves and 0.25 cup Olive Oil, then whisk to combine. Place the 1.5 lb Flank Steak in a large zip-top bag or shallow dish. Pour the marinade over the steak, turning to coat evenly. Seal the bag or cover the dish, then refrigerate for at least 2 hours or overnight.

The longer it marinates, the more tender and flavorful the steak will be. I like to marinate mine for 8 hours for maximum flavor penetration. Make sure to turn the steak halfway through the marinating time to ensure even flavor distribution.

🔥 Step 2: Roast the Flank Steak

Preheat your oven to 400°F. Remove the flank steak from the marinade, letting any excess liquid drip off. Place the steak on a rimmed baking sheet or roasting pan fitted with a wire rack. Roast in the preheated oven for 15-20 minutes until the internal temperature reaches 130-135°F for medium-rare or 140-145°F for medium. Use a meat thermometer to check for doneness.

For a more caramelized crust, broil the steak for an additional 2-3 minutes after roasting. Watch closely to prevent burning. The steak should have a nice brown crust on the outside while remaining juicy inside.

🥘 Step 3: Glaze with BBQ Sauce

Remove the steak from the oven and brush generously with 0.5 cup BBQ Sauce. If you prefer a thicker glaze, you can simmer the BBQ sauce in a saucepan over medium heat for 5 minutes until it thickens slightly before brushing it onto the steak. Return the steak to the oven and continue roasting for another 5 minutes until the sauce is caramelized and sticky.

The BBQ sauce adds a sweet and tangy flavor that complements the savory marinade. Make sure to brush the sauce evenly over the steak to get a consistent glaze.

🔪 Step 4: Rest and Slice the Steak

Transfer the cooked steak to a cutting board and let it rest for 10 minutes before slicing. This resting period allows the juices to redistribute throughout the meat, making it more tender and flavorful. Slice the steak against the grain into thin strips using a sharp knife.

Garnish with 0.25 cup chopped Fresh Cilantro before serving. The cilantro adds a fresh, herbaceous note that balances the rich flavors of the steak. Serve immediately and enjoy!

Regional Styles of This bbq flank steak recipe oven

Kansas City Style

The Kansas City BBQ style is known for its use of thick tomato-based sauces and slow cooking methods. For this version, I’d add 1/4 cup brown sugar to the marinade and use a Kansas City-style BBQ sauce for glazing. The result is a sweet and tangy flavor profile that’s characteristic of this region. 🔥

Carolina Style

In the Carolinas, vinegar-based sauces are more common. To give your BBQ flank steak a Carolina twist, replace the apple cider vinegar with white vinegar in the marinade and use a vinegar-based BBQ sauce for glazing. This style is perfect for those who prefer a tangier, less sweet BBQ flavor.

Memphis Style

Memphis-style BBQ often features dry rubs. For this variation, omit the marinade and instead use a dry rub made with 2 tbsp brown sugar, 1 tbsp smoked paprika, 1 tbsp garlic powder, and 1 tbsp onion powder. Rub this mixture all over the steak before cooking for a flavorful crust. 🌶️

Texas Style

Texas-style BBQ is all about beef and simplicity. To achieve this style, keep the marinade simple with just olive oil, garlic, and black pepper. Then, use a beef-based BBQ sauce for glazing. This style lets the natural flavor of the beef shine through.

Global Twists

For a Korean-style BBQ flank steak, add 2 tbsp Gochujang (Korean chili paste) to the marinade and use a Korean chili flake called gochugaru for added heat. You can also try other global flavors like Jamaican jerk or Indian-inspired spices to give your BBQ flank steak a unique twist. 🌟
