How Long to Cook Sirloin Steak on a Gas Grill? Timing Guide

Sirloin steak is a beef cut with a hearty flavor that grills well with just salt, pepper, and a little oil. For steaks about 1 inch thick, allow roughly 10–14 minutes over a hot gas grill, turning once; use a thermometer rather than time alone to judge when they are done.

Ingredients

2 boneless top sirloin steaks, about 1 inch (2.5 cm) thick and 8 oz (225 g) each
1 tsp (6 g) fine salt
½ tsp (1 g) freshly ground black pepper
1 tsp (5 ml) neutral oil, such as canola or avocado oil
1 tbsp (14 g) unsalted butter, optional, for serving

Instructions

Prepare the steaks. Take the steaks from the refrigerator while you set up the grill, but do not leave raw meat sitting out for an extended period. Pat both sides dry with paper towels; a dry surface browns more readily than a damp one. Rub the steaks lightly with the oil, then season both sides evenly with salt and pepper. Allow about 10 minutes for this preparation, including the time to gather the ingredients and utensils.
Preheat the gas grill. Clean the grates, close the lid, and heat the grill on high for about 15 minutes. Aim for a hot cooking surface, around 450–500°F (232–260°C) if your grill has a thermometer. If your grill heats unevenly, set one burner to high and leave an adjacent burner on low or off, creating a cooler area for finishing thicker steaks. Use the grill’s lid thermometer as a rough guide, not as a reading of the grate itself.
Grill the first side. Set the steaks over the hot part of the grill and close the lid. Cook for about 4–6 minutes without moving them. The exact time depends on steak thickness, starting temperature, grill heat, and wind. If the meat is sticking firmly when you try to lift an edge with tongs, give it another 30–60 seconds; a browned steak usually releases more readily.
Turn and continue cooking. Flip each steak once with tongs and cook the second side for about 4–6 minutes, keeping the lid closed between checks. Start checking the internal temperature after roughly 8 minutes of total grilling. Insert an instant-read thermometer sideways into the center of the thickest part, avoiding any bone or a large seam of fat. If the steak needs more time, move it to the cooler zone and check again every minute or two. For food safety, the USDA FSIS safe minimum for whole cuts of beef is 145°F (63°C), followed by a 3-minute rest; verify the temperature with a food thermometer.
Rest before slicing. Transfer the steaks to a clean plate and rest them for at least 3 minutes. This required rest is included in the recipe’s 32-minute cook estimate, along with the 15-minute grill preheat and up to 14 minutes of grilling. A small pat of butter can melt over each steak while it rests. Slice across the grain for more tender bites, or serve the steaks whole.

Tips

Let thickness set the timing. The 10–14-minute grilling estimate suits steaks close to 1 inch thick. A steak nearer 1½ inches may need extra time; sear it over high heat, then finish over the cooler zone with the lid down. Thin steaks cook quickly, so begin checking them early.
Use a thermometer, not the clock or finger test. Gas grills differ, and two steaks of the same weight can have different thicknesses. A quick temperature check in the center is the most reliable way to avoid serving an undercooked steak or leaving it on the grill until it becomes dry.
Keep the grill clean and avoid repeated flipping. Brush the grates before preheating and oil the steak lightly rather than pouring oil onto the grill. Turning once helps make timing easy to follow, but if a steak is browning too quickly, move it to indirect heat instead of letting the outside scorch.
Choose a simple substitute thoughtfully. Strip steak or flat iron steak can be grilled with the same seasoning, but their thickness and fat content may change the timing. Use the same thermometer target and check each cut independently. If using salted butter, reduce the salt sprinkled on the steaks a little.

Serving Suggestions

Serve the steak whole for a straightforward dinner, or slice it across the grain and arrange the pieces on a warm platter. A baked potato, grilled corn, or roasted potatoes makes a substantial side; green beans, a crisp salad, or grilled zucchini adds a lighter contrast. Spoon any juices left on the resting plate over the sliced meat, but do not return raw-meat juices to the serving plate unless they have been cooked thoroughly.

For a quick finishing touch, top each steak with the optional butter and a little extra black pepper. A squeeze of lemon or a spoonful of chimichurri gives the rich beef a brighter, herb-forward finish. If serving several sides, slice the steaks just before bringing them to the table so they stay warm and retain their juices.

Variations

Garlic-herb finish: Mix 1 tbsp (14 g) softened butter with 1 small minced garlic clove (about 3 g) and 1 tsp (1 g) chopped parsley. Put a small amount on each hot steak during its rest. This gives the surface a savory, buttery finish without changing the grilling method.
Smoky seasoning: Add ½ tsp (1 g) smoked paprika to the salt and pepper before grilling. It contributes a gentle smoky note, while the hot gas grill still provides the browned crust. Avoid adding sugary barbecue sauce early, since sugar can burn over direct heat; brush it on during the last minute instead.
Simple marinade: For a more seasoned interior, marinate the steaks in the refrigerator for 30 minutes to 4 hours in 2 tbsp (30 ml) olive oil, 1 tbsp (15 ml) soy sauce, and 1 tsp (5 ml) lemon juice. Pat the meat dry before grilling so it browns instead of steaming. The soy sauce adds salt, so use less of the measured salt in the main recipe.

Storage and Reheating

Refrigerate leftover steak within 2 hours of cooking, in a shallow airtight container. It keeps for 3–4 days in the refrigerator. For longer storage, wrap it tightly and freeze it; it is best used within about 2–3 months for quality. Thaw frozen steak in the refrigerator rather than on the counter.

Reheat only the amount you plan to eat. Warm slices gently in a covered skillet with a spoonful of water or broth, or heat the steak in a low oven until hot, then briefly sear it if you want a browned surface again. For food safety, leftovers should reach 165°F (74°C), checked with a thermometer. Reheating can make steak firmer, so cut it into slices before warming and avoid leaving it over high heat longer than necessary.

Frequently Asked Questions

How long does a 1-inch sirloin steak take on a gas grill?

Plan on about 10–14 minutes of grilling over high heat, turning once, then rest the steak for at least 3 minutes. That is a guide, not a guarantee: grill performance, steak shape, and how often the lid is opened all affect the time. Check the thickest part with a thermometer and follow the safe minimum temperature in the instructions.

Should I grill sirloin with the lid open or closed?

Close the lid while the grill preheats and for most of the cooking. A closed lid helps the grill maintain heat and cook the steak more evenly. Open it briefly to turn the meat or check its temperature, then close it again so the grill does not lose heat unnecessarily.

Can I grill a thicker sirloin steak the same way?

Yes, but do not rely on the 10–14-minute estimate for a thicker steak. Sear both sides over the hot zone, then move the steak to indirect heat and close the lid until its center reaches the required temperature. Check frequently near the end; the thermometer is more useful than adding a fixed number of minutes.

Do I need to bring sirloin steak to room temperature first?

No. You can season the steak while the grill heats and cook it straight from the refrigerator. A short time on the counter while you prepare the grill is fine, but leaving raw beef out for a long period does not make grilling more predictable. Drying the surface and preheating the grill matter more for browning.

Why is my steak sticking to the grill?

The grates may not be hot or clean enough, or the steak may need a little longer to brown before it releases. Preheat the grill, brush the grates clean, and coat the meat lightly with oil. Lift an edge gently with tongs; do not force it or scrape the steak across the grates.

Can I grill sirloin from frozen?

For more even cooking and easier temperature checks, thaw the steak in the refrigerator first. A frozen steak can brown before its center is ready, making the timing especially difficult to judge. Once thawed, pat it dry, season it, and follow the same thermometer-guided method.
