Grilling the perfect sirloin steak is all about timing and technique. Whether you’re a seasoned grill master or just starting out, knowing how long to grill your steak can make all the difference between juicy and overcooked.
You want your sirloin to have that ideal balance of a flavorful crust and tender inside. Getting the timing right ensures you enjoy every bite with maximum flavor and texture. In this guide, you’ll discover the best grilling times for different thicknesses and doneness levels so you can confidently fire up the grill and impress your guests.
Factors Affecting How Long to Grill Sirloin Steak
Several key factors influence the grilling time for your sirloin steak. Understanding these helps you achieve the perfect balance of sear and internal tenderness.
Thickness of the Steak
Thickness directly impacts grilling time. Thicker steaks, such as 1.5 inches or more, need longer cooking times, typically 6 to 8 minutes per side for medium-rare. Thinner cuts, around 0.5 to 1 inch, require 3 to 4 minutes per side to avoid overcooking. Measure the steak’s thickness before grilling to time it accurately.
Desired Level of Doneness
Your target doneness alters the grilling duration significantly. Use these internal temperature guidelines:
- Rare: 120°F to 125°F, about 4 minutes per side (thin steaks)
- Medium-rare: 130°F to 135°F, 5 to 7 minutes per side
- Medium: 140°F to 145°F, 6 to 8 minutes per side
- Medium-well: 150°F to 155°F, 8 to 10 minutes per side
- Well-done: 160°F and above, 10+ minutes per side
Use a meat thermometer for precision, since visual cues vary and carry risks of over or undercooking.
Grill Temperature and Type
Grill temperature and equipment affect cooking speed and evenness. High heat grills (450°F to 500°F) sear steaks quickly, creating a crust but require close monitoring to prevent burning. Medium heat grills (350°F to 450°F) cook steaks more evenly but need longer durations. Gas grills offer consistent temperatures, while charcoal grills provide higher heat variability and smoky flavors but need adjustments during cooking. Adjust grilling time based on your grill’s heat output and stability.
Recommended Grilling Times for Sirloin Steak
Grilling times vary based on steak thickness and desired doneness. Use these guidelines to achieve consistent results with your sirloin steak.
Rare to Medium-Rare
Grill a 1-inch sirloin steak for 4-5 minutes per side over high heat (450°F to 500°F) to reach rare (125°F internal temperature) or medium-rare (135°F). For thicker steaks, add 1-2 minutes per side. Rest steaks 5 minutes after grilling to allow juices to redistribute.
Medium to Medium-Well
Cook a 1-inch sirloin steak for 6-7 minutes per side to reach medium (145°F) or medium-well (150°F). Thicker cuts require roughly 2 additional minutes per side. Monitor internal temperature with a meat thermometer for precision and avoid overcooking.
Well-Done
Grill sirloin steaks for 8-10 minutes per side until the internal temperature reaches 160°F or above. Thicker steaks need 3-4 extra minutes per side. Keep the grill at medium heat (350°F to 400°F) to prevent excessive charring while ensuring thorough cooking.
Tips for Perfectly Grilled Sirloin Steak
Mastering sirloin steak grilling relies on preparation, precise temperature measurement, and proper resting. Follow these practices to elevate your steak grilling results.
Preparing the Steak Before Grilling
Season your sirloin steak generously with salt and pepper at least 40 minutes before grilling to enhance flavor and improve texture. Bring the steak to room temperature before cooking to ensure even grilling. Apply a thin layer of oil to prevent sticking and to promote a well-browned crust. Avoid overcrowding the grill, giving each steak ample space for heat circulation.
Using a Meat Thermometer
Use a reliable meat thermometer to check internal temperature, ensuring your steak reaches the desired doneness without guesswork. Insert it into the thickest part of the steak, avoiding contact with bone or fat for accuracy. Target these temperatures in Fahrenheit: 125°F for rare, 135°F for medium-rare, 145°F for medium, 150°F for medium-well, and 160°F for well-done. Remove the steak from heat a few degrees below the target temperature since it continues to cook while resting.
Resting the Steak After Grilling
Rest your sirloin steak 5 to 10 minutes after grilling to allow juices to redistribute evenly, increasing tenderness and juiciness. Cover loosely with aluminum foil to retain warmth while avoiding steam build-up that can soften the crust. Slice against the grain to maximize tenderness once rested.
Conclusion
Grilling the perfect sirloin steak is all about timing and attention to detail. By understanding how thickness, doneness, and grill temperature affect cooking time, you can confidently achieve a juicy and flavorful result every time. Using a meat thermometer and allowing your steak to rest will elevate your grilling game and impress anyone at your table. With these tips, you’re ready to enjoy a tender sirloin steak cooked just the way you like it.
