Learn how to cook a perfect top sirloin steak in the oven with this easy method involving searing on the stovetop followed by oven roasting. This process locks in juices and flavor with garlic, rosemary, and butter, delivering a tender, flavorful steak every time.

Ingredients

Steak and Seasoning

  • 1 LB top sirloin steak
  • 1/4 tsp salt
  • 1/8 tsp pepper

Cooking Ingredients

  • 1 tbsp olive oil
  • 1 tbsp salted butter
  • 2 tsp minced garlic
  • 3 sprigs fresh rosemary

Instructions

  1. Preheat Oven: Preheat your oven to 375 degrees Fahrenheit to prepare for finishing the steak in the oven.
  2. Season Steak: Season the top sirloin steak evenly with salt and pepper on both sides to enhance its natural flavors.
  3. Sear Steak: Heat a large cast iron skillet over medium-high heat and add the olive oil. When the oil starts to smoke slightly, place the seasoned steak in the skillet and sear without moving it for 3 minutes to develop a brown crust.
  4. Flip and Add Flavor: Flip the steak and sear for an additional 1 minute. Turn off the burner, then add the butter, minced garlic, and fresh rosemary sprigs on top of the steak to infuse it with rich flavors while it finishes cooking in the oven.
  5. Oven Cook: Transfer the skillet with the steak into the preheated oven. Roast the steak for 5 to 7 minutes, or until the internal temperature reaches 135°F for rare, 140-145°F for medium, or your preferred doneness. Using a probe thermometer is recommended for precision.
  6. Rest: Remove the steak from the oven and transfer it to a cutting board. Allow it to rest for 10 minutes so the juices redistribute and the steak remains juicy and tender.
  7. Serve: Serve the steak as is or with your favorite steak sauce for an enhanced dining experience.

Notes

  • Use a cast iron skillet for even heat distribution and optimal searing.
  • Resting the steak is crucial to retain juices and improve tenderness.
  • Cooking times vary based on steak thickness and desired doneness—using a meat thermometer ensures perfect results.
  • Fresh rosemary and garlic add aromatic flavor that complements the beef.
