The beef loin top sirloin must be well-marbled and at least 1.5 inches thick for proper searing and even cooking. Source from a reputable butcher or high-end grocer like Whole Foods for consistent quality. Look for vibrant red color with fat evenly distributed. Bringing the steak to room temperature before grilling is non-negotiable for professional results.

No fresh rosemary or thyme? Dried herbs at one-third the amount work, but fresh delivers superior aroma. Short on red wine? Substitute beef stock with a splash of balsamic vinegar. The butter can be omitted, but it adds a luxurious finish. For the olive oil, avocado oil offers a higher smoke point if you’re concerned about flare-ups.

Store uncooked steak in the coldest part of your fridge for 2-3 days max. The herb mixture can be prepped 1 day ahead and refrigerated. Leftover cooked steak keeps 3-4 days but is best enjoyed immediately for optimal texture and flavor.

Step-by-Step Instructions for Beef Loin Top Sirloin Grill

Master these techniques for perfect char and juicy centers with every cook.

Step 1: Season and Marinate the Steak

Begin by patting the 2 lb Beef Loin Top Sirloin Steak completely dry with paper towels. This critical step ensures a proper sear. Rub the entire surface with the 4 cloves Garlic Cloves, then coat evenly with the 2 tbsp Kosher Salt and 1 tbsp Freshly Ground Black Pepper.

In a small bowl, combine the 0.25 cup Extra-Virgin Olive Oil with the chopped 2 whole Fresh Rosemary Sprigs and leaves from the 4 whole Fresh Thyme Sprigs. Rub this mixture over the steak, massaging it into the meat. Let it sit at room temperature for 30-45 minutes to allow the flavors to penetrate.

Step 2: Preheat the Grill to High Heat

Preheat your grill to high heat (about 450-500°F). Clean the grates thoroughly with a grill brush to prevent sticking. You want the grates screaming hot—when you hover your hand 5 inches above, you should only be able to hold it there for 2-3 seconds.

While the grill heats, place the 4 tbsp Unsalted Butter in a small saucepan and set it near the grill to soften slightly. This will be used for basting during cooking. The high heat is essential for creating a deep, flavorful crust on the steak.

Step 3: Sear and Baste the Steak

Place the steak on the grill and sear undisturbed for 4-5 minutes until a deep, dark brown crust forms. Flip the steak and immediately begin basting with the softened unsalted butter, using a silicone brush or spoon. Continue basting every 30 seconds while cooking.

Cook for another 4-5 minutes for medium-rare, or until the internal temperature reaches 130-135°F. For a 1.5-inch thick steak, this timing should yield a perfect pink center. Avoid pressing the steak with your tongs—this squeezes out precious juices.

Step 4: Rest and Prepare the Pan Sauce

Transfer the steak to a cutting board and tent loosely with foil. Let it rest for 10 minutes—this allows the juices to redistribute. Meanwhile, finely mince the 1 whole Shallot and place it in a small saucepan with the 0.25 cup Red Wine and 0.5 cup Beef Stock.

Simmer the mixture over medium heat for 5-7 minutes until reduced by half. Stir in the 1 tbsp Dijon Mustard and any accumulated juices from the resting steak. The sauce should coat the back of a spoon lightly.

Step 5: Slice and Serve

Slice the steak against the grain into ½-inch thick portions. This shortens the muscle fibers, ensuring maximum tenderness. Arrange the slices on a platter and drizzle with the warm red wine sauce.

Serve immediately while the steak is still warm. The exterior should have a robust char, while the interior remains succulent and rosy. Each bite should deliver the bold flavors of the herb marinade and smoky grill marks.

Pro Cooking Tips for Great beef loin top sirloin grill

Perfect Grill Marks

For those beautiful crosshatch patterns, rotate your steak 45 degrees halfway through each side’s cooking time. I use long-handled tongs to make this quick and safe. The key is high heat and not moving the steak too soon. 🔥

Temperature Control

Invest in a good instant-read thermometer—I swear by my ThermoWorks Thermapen. For medium-rare, pull the steak at 130°F internal temperature. Remember, the temperature will rise 5-10°F during resting, which is why we don’t cook to the final temp on the grill.

Herb Infusion

For extra flavor, toss whole herb sprigs directly on the coals 5 minutes before grilling. The smoke infuses the meat with aromatic complexity. I often use extra rosemary and thyme from my garden for this. The scent alone will make your mouth water.

Butter Basting Pro Tip

Add a crushed garlic clove and a rosemary sprig to your butter as it melts for basting. This creates a compound butter effect right on the grill. Baste continuously during the last 2 minutes of cooking for maximum flavor infusion.

Resting Essentials

Never skip resting—it’s non-negotiable for juicy results. Tent the steak loosely with foil and let it rest for a full 10 minutes. I learned this the hard way when all my juices ended up on the cutting board instead of in the meat. 💡

Grill Maintenance

Clean your grates thoroughly between uses with a brass-bristle brush. I also oil my grates with a paper towel dipped in avocado oil before preheating. This prevents sticking and helps achieve that perfect sear every time.
