Ingredients
Main Ingredients
- 4 pounds beef top sirloin steaks (about 4 steaks)
- ½ cup (1 stick) unsalted butter, softened
- 4 cloves garlic, minced
- 2 teaspoons garlic powder
- Salt and black pepper, to taste
Optional Add-ins
- Fresh parsley or rosemary (stir into the butter for herbaceous flair)
- A pinch of red pepper flakes (for subtle heat in the butter)
- Lemon zest (brightens the butter beautifully)
- Worcestershire sauce, ½ tsp (brushed on the steak before grilling)
Step-by-Step Instructions
- Remove the steaks from the refrigerator 30 minutes before cooking. This helps them cook more evenly from edge to center. Preheat your grill to high heat.
- While the grill heats, make the garlic butter. In a small saucepan or microwave-safe bowl, melt the butter. Stir in the minced garlic and garlic powder and set aside.
- Season both sides of each steak generously with salt and freshly ground black pepper.
- Place the steaks on the hot grill. Cook for 4–5 minutes per side for medium-rare, or adjust to your preferred doneness. Use a meat thermometer: 130°F for medium-rare, 140°F for medium.
- Transfer the steaks to plates. Brush the tops liberally with the warm garlic butter. Tent loosely with foil and let rest for 3–5 minutes before serving. This rest time is what keeps the juices locked inside.
Pro Tips
- Let the steaks come to room temperature before grilling for even cooking throughout.
- Don’t press down on the steaks with a spatula — this squeezes out all those precious juices.
- A meat thermometer is the only reliable way to hit your target doneness. Remove steaks 5°F before target — they carry-over cook while resting.
- For a pan-seared version, use a cast iron skillet on the stove over high heat with a tablespoon of oil.
- Compound butter can be made ahead: roll into a log, wrap in plastic wrap, refrigerate for up to 2 weeks, and slice off pats as needed.
Variations & Substitutions
This garlic butter method works equally well on ribeye, New York strip, T-bone, or flank steak. For a herb compound butter, add chopped fresh thyme, rosemary, and parsley. Try a blue cheese butter variation — crumble blue cheese into softened butter with garlic. For indoor cooking, use a screaming-hot cast iron skillet and finish in a 400°F oven.
What to Serve With
Classic pairings include garlic mashed potatoes, roasted asparagus, or a crisp wedge salad. Grilled corn on the cob or sautéed mushrooms are also excellent. Finish the meal with a glass of bold red wine — a Cabernet Sauvignon or Malbec is a natural match.
Storage & Reheating
Cooked steak keeps in the fridge for up to 3 days in an airtight container. Reheat gently in a skillet over medium-low heat with a small pat of butter to keep it juicy — avoid the microwave, which dries it out. Leftover steak is incredible sliced thin over a salad or in a wrap.
