Grilling enthusiasts and meat lovers alike are always on the lookout for the perfect cut of beef that combines flavor, tenderness, and versatility. One such cut that has gained significant popularity is the flank steak. When prepared correctly, a Traeger Flank Steak can be a showstopper at any barbecue or family gathering. This guide will walk you through everything you need to know about selecting, preparing, and cooking a Traeger Flank Steak to perfection.
Understanding Flank Steak
Flank steak is a long, flat cut of beef taken from the abdominal muscles of the cow. It is known for its rich, beefy flavor and relatively lean composition. While it can be somewhat tough if not cooked properly, the right techniques can transform it into a tender and juicy delight. Flank steak is versatile and can be used in a variety of dishes, from fajitas to stir-fries, but it truly shines when grilled.
Selecting the Perfect Flank Steak
Choosing the right flank steak is the first step to a successful grilling experience. Here are some tips to help you select the best cut:
- Marbling: Look for a steak with good marbling, which refers to the thin streaks of fat within the meat. Marbling enhances flavor and tenderness.
- Color: The meat should have a bright red color, indicating freshness. Avoid steaks that are dull or have a brownish tint.
- Thickness: Aim for a steak that is about 1 to 1.5 inches thick. This thickness ensures even cooking and prevents overcooking.
- Trim: Check for excess fat on the edges. While some fat is desirable for flavor, too much can lead to flare-ups on the grill.
Preparing Your Traeger Flank Steak
Preparation is key to achieving a perfectly cooked Traeger Flank Steak. Follow these steps to ensure your steak is ready for the grill:
Marinating
Marinating your flank steak can significantly enhance its flavor and tenderness. Here is a simple marinade recipe to get you started:
- 1/4 cup soy sauce
- 2 tablespoons olive oil
- 2 tablespoons Worcestershire sauce
- 2 tablespoons lemon juice
- 2 cloves garlic, minced
- 1 teaspoon dried oregano
- 1 teaspoon dried thyme
- 1/2 teaspoon black pepper
Combine all the ingredients in a bowl and mix well. Place your flank steak in a zip-top bag or a non-reactive dish, pour the marinade over the steak, and seal the bag. Refrigerate for at least 2 hours, or up to 24 hours for maximum flavor.
🍽️ Note: Avoid using acidic ingredients like vinegar or citrus juice in large quantities, as they can break down the meat's proteins and make it mushy.
Seasoning
If you prefer not to marinate, you can season your flank steak with a dry rub. Here is a simple recipe:
- 1 tablespoon kosher salt
- 1 tablespoon black pepper
- 1 tablespoon paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried oregano
- 1 teaspoon dried thyme
Mix all the ingredients in a small bowl. Pat the steak dry with paper towels and generously apply the rub on both sides. Let it sit at room temperature for about 30 minutes before grilling.
Cooking Your Traeger Flank Steak
Now that your flank steak is prepared, it's time to fire up your Traeger grill. Follow these steps for a perfectly cooked Traeger Flank Steak:
Preheating the Grill
Preheat your Traeger grill to 450°F (230°C) for about 15 minutes. This ensures that the grill is hot and ready for searing the steak.
Searing the Steak
Place the flank steak on the grill grates and sear for 4-5 minutes on each side. This will create a beautiful crust and lock in the juices.
Cooking to Desired Doneness
After searing, reduce the grill temperature to 350°F (175°C). Continue cooking the steak until it reaches your desired level of doneness. Use a meat thermometer to check the internal temperature:
| Doneness | Internal Temperature | Cooking Time |
|---|---|---|
| Rare | 125°F (52°C) | 8-10 minutes |
| Medium-Rare | 135°F (57°C) | 10-12 minutes |
| Medium | 145°F (63°C) | 12-14 minutes |
| Medium-Well | 155°F (68°C) | 14-16 minutes |
| Well-Done | 160°F (71°C) | 16-18 minutes |
Remember that the steak will continue to cook slightly after you remove it from the grill, a phenomenon known as carryover cooking.
Resting the Steak
Once the steak reaches your desired doneness, remove it from the grill and let it rest for 10-15 minutes. This allows the juices to redistribute throughout the meat, ensuring a juicier and more flavorful steak.
🍽️ Note: Cover the steak loosely with aluminum foil during the resting period to keep it warm.
Slicing and Serving Your Traeger Flank Steak
Slicing a flank steak correctly is crucial for maximizing tenderness and flavor. Follow these steps:
Against the Grain
Identify the direction of the grain in the steak. The grain refers to the lines of muscle fibers running through the meat. Slice the steak thinly against the grain, at a 45-degree angle if possible. This shortens the muscle fibers, making the steak more tender and easier to chew.
Thin Slices
Cut the steak into thin slices, about 1/4 inch thick. This ensures that each bite is tender and flavorful. Arrange the slices on a platter and serve immediately.
Serving Suggestions
Your Traeger Flank Steak can be served in a variety of ways. Here are some ideas:
- Classic: Serve the steak with a side of roasted vegetables, mashed potatoes, or a fresh salad.
- Fajitas: Slice the steak into thin strips and serve with warm tortillas, sautéed peppers and onions, and your favorite toppings.
- Salad: Top a bed of mixed greens with sliced flank steak, cherry tomatoes, cucumbers, and a tangy vinaigrette.
- Sandwiches: Use the sliced steak to make delicious sandwiches with your favorite bread, cheese, and condiments.
Your Traeger Flank Steak is now ready to be enjoyed! The combination of rich flavor, tender texture, and smoky aroma from the Traeger grill makes it a standout dish that will impress your family and friends.

In conclusion, mastering the art of cooking a Traeger Flank Steak involves selecting the right cut, preparing it with care, and cooking it to perfection. By following the steps outlined in this guide, you can achieve a delicious and tender flank steak that will be the highlight of any meal.
