Ingredients for Recipe Using Sirloin Steak

Transform affordable sirloin into a restaurant-quality meal with these essential ingredients.

The steak quality is paramount here. USDA Choice sirloin offers the best balance of flavor and affordability. Look for pieces with good marbling and a bright red color. Most butchers at Whole Foods or local meat markets will cut custom thicknesses if requested. For the butter, European-style unsalted has a higher fat content, which browns beautifully and adds richness to the finish.

Out of red wine? Beef broth with a teaspoon of balsamic vinegar works in a pinch. Fresh herbs can be swapped for dried at one-third the amount, though the flavor profile will be slightly different. If rosemary isn’t available, fresh sage offers a complementary earthy note. For the oil, any neutral high-smoke-point variety like avocado or grapeseed can replace canola without issue.

Sirloin keeps well in the fridge for 3-4 days if properly wrapped. The garlic butter can be made ahead and stored in the fridge for up to 1 week. For best results, bring the steak to room temperature before cooking—this ensures even cooking throughout.

Step-by-Step Instructions for Cast Iron Sear With Garlic Butter Finish

Master the perfect sear and finish with these precise, professional techniques.

Step 1: Season and Temper the Sirloin Steak

Pat the 2 lb sirloin steak completely dry with paper towels—this ensures a perfect sear. Season uniformly with the 1.5 tsp kosher salt and 1 tsp freshly ground black pepper, pressing gently so the seasoning adheres to all surfaces.

Let the steak rest at room temperature for 30-45 minutes before cooking. This step is non-negotiable for even cooking, as cold meat seizes up in the pan and cooks unevenly. Meanwhile, take the 4 cloves garlic cloves, smash them lightly, and peel.

Step 2: Preheat Pan and Sear the Steak

Place a heavy cast iron skillet over medium-high heat and add the 1 tbsp canola oil. Once the oil begins to shimmer and a drop of water sizzles violently, it’s ready. Add the steak and sear undisturbed for 3-4 minutes per side until a deep, dark brown crust forms.

For even cooking, sear the edges of the steak by holding it with tongs for 30 seconds per edge. The steak should release easily from the pan when it’s ready to flip—if it sticks, let it cook longer to develop the crust. Add the 2 sprigs fresh rosemary sprigs and 2 sprigs fresh thyme sprigs to the pan during the last minute of searing for aroma.

Step 3: Baste with Garlic Butter

Reduce heat to medium. Add 2 tbsp unsalted butter, the smashed garlic cloves, and the 1 whole minced shallot to the pan. Tilt the pan slightly and spoon the melted butter continuously over the steak for 1-2 minutes to baste.

The butter should foam and turn a light golden brown, infusing the steak with rich, aromatic flavor. The garlic and shallot will soften and perfume the butter. Remove the steak from the pan once it reaches an internal temperature of 125°F for medium-rare, and transfer it to a cutting board to rest.

Step 4: Deglaze and Finish the Sauce

Remove the pan from heat and carefully pour in the 0.25 cup red wine to deglaze. Use a wooden spoon to scrape up all the browned bits from the bottom of the pan—these are packed with flavor. Return the pan to medium heat and simmer for 2-3 minutes until the liquid reduces by half.

Stir in the remaining 2 tbsp unsalted butter until fully melted and emulsified into the sauce. The sauce should be glossy and coat the back of a spoon. Taste and adjust seasoning if needed, though the initial seasoning on the steak should suffice.

Step 5: Rest, Slice, and Serve

Let the steak rest for 10 minutes before slicing. This allows the juices to redistribute, ensuring every bite is tender and flavorful. Slice against the grain into ½-inch thick pieces.

Spoon the garlic butter sauce over the sliced steak and serve immediately. The steak should be juicy and tender with a deeply caramelized crust, and the sauce should pool slightly around each slice, ready to be soaked up with each bite.

Make-Ahead Tips for This recipe using sirloin steak

Prep the Steak Ahead

Pat the 2 lb sirloin steak dry and season with 1.5 tsp kosher salt and 1 tsp black pepper up to 12 hours before cooking. Store it uncovered in the fridge to develop a dry brine that enhances flavor and tenderness. 💡

Make Garlic Butter Early

Combine 4 tbsp unsalted butter, 4 smashed garlic cloves, and 1 minced shallot in a small bowl. This can be refrigerated for up to 3 days. Let it soften slightly before using to melt evenly in the pan.

Pre-Cook Sides

Roast vegetables or toss a salad 1 hour before serving. Keep them warm in a 200°F oven while you sear the steak. This ensures everything hits the table hot and fresh.

Preheat the Pan

If using cast iron, place it in the oven at 200°F while prepping. A warm pan reduces searing time by 1-2 minutes and promotes even cooking. I always notice a better crust with this step.

Rest Before Slicing

After cooking, tent the steak loosely with foil and rest for 10 minutes. This can be done while you finish the sauce or set the table. Slicing too soon causes juices to escape. 🔥

Reheat Gently

If serving later, store cooked steak in the fridge for up to 3 days. Reheat slices in a skillet over low heat with a splash of beef broth for 2-3 minutes per side.
