How to Cook the Perfect Traeger London Broil with Blue Cheese Butter

The London Broil with Blue Cheese Butter recipe from Traeger Grills transforms a tough cut of beef into a tender, flavorful dish. The steak is marinated in a mixture of soy sauce, water, onion, garlic, red wine vinegar, oil, ketchup, Worcestershire sauce, pepper, and sugar. After marinating, the steak is smoked and then grilled to perfection. It is topped with a rich blue cheese butter made from softened butter, scallion, crumbled blue cheese, Worcestershire sauce, and pepper. This recipe serves four and involves a prep time of 10 minutes and a cook time of 1 hour and 20 minutes.

Steps:

1. Prepare the Marinade: Whisk together soy sauce, water, onion, garlic, red wine vinegar, oil, ketchup, Worcestershire sauce, pepper, and sugar in a small bowl.
2. Marinate the Steak: Place the steak in a large resealable plastic bag, pour the marinade over it, and refrigerate for 6 hours or overnight.

5. Prepare the Steak: Remove the steak from the bag, discard the marinade, pat dry with paper towels, and season with Traeger Beef Rub.
6. Smoke the Steak: Insert the probe into the thickest part of the steak, place it on the grill grates, close the lid, and smoke for 60 minutes.
7. Make Blue Cheese Butter: Mix together butter, scallion, blue cheese, Worcestershire sauce, and pepper in a small bowl, then refrigerate.
8. Increase Grill Temperature: Transfer the steak to a platter, increase the grill temperature to 450℉, and preheat with the lid closed.
9. Grill the Steak: Return the steak to the grill, re-insert the probe, and cook until the internal temperature reaches 130℉ for medium-rare, about 15-20 minutes.
