Ingredients

Instructions

  1. Step 1: Preheat the grill to medium-high heat (around 400°F). Brush each of the 4 beef tenderloin medallions with 2 tbsp olive oil, then season evenly with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Place the medallions on the grill and cook for 4-5 minutes per side for medium-rare, until the surface develops grill marks and the internal temperature reaches 135°F.
  3. Step 3: While the beef cooks, melt 4 tbsp unsalted butter in a small saucepan over low heat. Add 3 minced garlic cloves and 1 tbsp chopped fresh rosemary, stirring continuously for 2 minutes until fragrant and the butter is infused.
  4. Step 4: Remove the beef from the grill and let rest for 5 minutes. Spoon the garlic rosemary butter over each medallion before serving, allowing the flavors to meld and the butter to melt into the meat.
