Sirloin Steak Ingredients

Butter (½ cup) – The rich, creamy base for the garlic butter that gives the steak its signature flavor.
Garlic, minced (4 cloves) – Fresh garlic adds bold, savory notes that pair perfectly with the beef. You can use pre-minced garlic or mince it yourself.
Beef top sirloin steaks (4 pounds) – A flavorful, tender cut that grills beautifully without breaking the bank. This recipe will work for all your favorite cuts, including Ribeye, New York strip, or flank steak.
Garlic salt with parsley flakes (to taste) – Season the meat and enhance the buttery garlic flavor with a hint of herby freshness. Mix about 1 teaspoon garlic salt with ¼ teaspoon dried parsley to make your own version.
Black pepper (to taste) – Adds a little kick and helps balance the richness of the butter.

Kristyn’s Recipe Tips

Bring steaks to room temp. Let your steaks sit out for about 30 minutes before grilling so they cook more evenly.
Use a meat thermometer. For perfect doneness, aim for 135°F for medium-rare or 145°F for medium.
Don’t skip the rest. After grilling, cover the steaks with foil for 5 minutes; this keeps them juicy and tender.
Other cuts. This recipe will work for all your favorite cuts, including Ribeye, New York strip, or flank steak.
Garlic+Parsley. Mix about 1 teaspoon garlic salt with ¼ teaspoon dried parsley to make your own version.
