Step‑by‑Step Instructions for Garlic Butter Sirloin Steak
Step 1: Prep Steaks
Remove the sirloin steaks from the refrigerator and let them sit at room temperature for about 30 minutes. This step ensures even cooking throughout. Meanwhile, you can gather your other ingredients and prepare the garlic butter mixture for later use.
Step 2: Season Steaks
Pat the steaks dry with paper towels to enhance the searing process. Generously season both sides with salt and pepper, making sure to rub it in well. This seasoning creates a delicious crust on the Garlic Butter Sirloin Steak, elevating its flavor.
Step 3: Heat Skillet
In a heavy skillet or cast-iron pan, heat about 2 tablespoons of olive oil over medium-high heat. Allow the oil to shimmer, which indicates it’s hot enough for searing. This step is crucial for achieving that beautifully browned crust on your steak.
Step 4: Sear Steaks
Carefully place the seasoned steaks in the skillet without overcrowding the pan. Sear the steaks for about 2 minutes on each side until a deep brown crust forms. Look for a golden-brown color that signals they are ready to flip, locking in all the delicious juices.
Step 5: Finish Cooking
Lower the heat to medium and continue cooking the steaks for an additional 2 to 3 minutes per side. Use a meat thermometer to check for the desired doneness, aiming for an internal temperature of 145°F for medium. This step ensures a tender and juicy Garlic Butter Sirloin Steak.
Step 6: Make Garlic Butter
While the steaks are cooking, combine softened unsalted butter, minced garlic, chopped parsley, and fresh thyme in a small bowl. Mix until well blended and add a pinch of salt and pepper to taste. This aromatic garlic butter will elevate your finished steak dramatically.
Step 7: Rest Steaks
Once cooked to your liking, remove the steaks from the skillet and top them generously with the garlic butter mixture. Let the steaks rest for about 5 minutes off the heat. Resting allows the juices to redistribute, ensuring each bite of your Garlic Butter Sirloin Steak is moist and flavorful.
Step 8: Cook Asparagus
In the same skillet, add trimmed asparagus and sauté for 8 to 10 minutes, stirring occasionally until tender. The residual flavors in the pan enhance the asparagus’ natural taste, providing a fantastic side to complement your Garlic Butter Sirloin Steak.

Expert Tips for Garlic Butter Sirloin Steak
