Ingredients

• 2 pieces (8 oz each) sirloin steaks
• 1 teaspoon salt
• 1 teaspoon black pepper
• 2 tablespoons olive oil
• 4 tablespoons unsalted butter
• 2 pieces garlic cloves, minced
• 1 cup baby bella mushrooms, finely chopped
• 1 tablespoon fresh parsley, finely chopped
• 1 teaspoon lemon juice

Directions

Step 1

Remove the sirloin steaks from the refrigerator and allow them to come to room temperature for about 20 minutes.

Step 2

Season both sides of the steaks with salt and black pepper, pressing gently to adhere the seasoning.

Step 3

Preheat your grill to medium-high heat or prepare a grill pan on the stovetop.

Step 4

Brush the steaks lightly with 1 tablespoon of olive oil on each side to prevent sticking during grilling.

Step 5

Place the steaks on the hot grill and cook for approximately 4–5 minutes per side for medium-rare, or adjust the time based on your preferred level of doneness. Use a meat thermometer if needed (130°F for medium-rare, 140°F for medium).

Step 6

While the steaks are grilling, prepare the garlic mushroom butter. Heat the remaining tablespoon of olive oil in a small skillet over medium heat.

Step 7

Add the minced garlic and sauté for 1–2 minutes, until fragrant but not browned.

Step 8

Add the finely chopped mushrooms and cook for 4–5 minutes, stirring occasionally, until softened and slightly golden.

Step 9

Remove the skillet from the heat and let the mixture cool slightly. In a small bowl, combine the softened unsalted butter with the cooked mushroom mixture, parsley, and lemon juice. Mix well to form a compound butter.

Step 10

Once the steaks are finished cooking, remove them from the grill and let them rest for 5 minutes to allow the juices to redistribute.

Step 11

Top each steak with a generous dollop of garlic mushroom butter and serve immediately with your favorite sides.
