How Long to Grill Steak on a Gas Grill

For a 1-inch thick steak on a gas grill preheated to 450–500°F, grill 4–5 minutes per side for medium-rare, 5–6 for medium, and 6–7 for medium-well. Always use a meat thermometer to confirm: 130–135°F for medium-rare, 140–145°F for medium, 150–155°F for medium-well. Thicker cuts need more time; thinner less. Let steak rest 5 minutes before slicing.

Quick Answer

The key variables are steak thickness, grill temperature, and desired doneness. Use direct heat, flip once, and trust the thermometer.

Thickness matters: For each additional 1/2 inch, add about 2 minutes per side.
Grill temp range: 450–500°F is ideal for a good sear without burning.
Flip only once: Flipping multiple times can cause uneven cooking and moisture loss.
Carryover cooking: Internal temp rises 5°F during rest; remove steak 5°F below target.
Resting is crucial: Rest 5 minutes to redistribute juices; slicing too early makes it dry.

Preheat and Prepare Your Gas Grill

Start by cleaning the grates with a wire brush to remove residue. Preheat your gas grill on high with the lid closed for 10–15 minutes until it reaches 450–500°F. A hot grill ensures a good sear. While it heats, take your steak out of the fridge and let it sit at room temperature for 20–30 minutes. Pat it dry with paper towels, then season generously with kosher salt and freshly ground black pepper. Avoid adding salt too early if you’re concerned about drawing out moisture – seasoning right before grilling is fine.

Grilling Times by Doneness for 1-Inch Steak

Use these times as a baseline for a 1-inch thick steak on a preheated gas grill at 450–500°F. Always verify with an instant-read thermometer.

Rare (125°F): 3–4 minutes per side
Medium-Rare (130–135°F): 4–5 minutes per side
Medium (140–145°F): 5–6 minutes per side
Medium-Well (150–155°F): 6–7 minutes per side
Well Done (160°F+): 7–8 minutes per side

For steaks thicker than 1 inch, add 2 minutes per side for each extra half inch. For thinner steaks (3/4 inch), reduce time by 1 minute per side. If using a two-zone fire (direct heat on one side, indirect on the other), you can sear over direct heat for the first minutes, then move to indirect to finish without burning.

How to Flip and Check Doneness

Place steaks on the hottest part of the grill. Cook the first side without moving for the time listed above. Flip once using tongs – never a fork, which pierces the meat and releases juices. Cook the second side for the same time. To check doneness, insert an instant-read thermometer into the thickest part of the steak, away from bone. For medium-rare, remove at 130°F; the temperature will rise to 135°F during rest. If you don’t have a thermometer, use the finger test: touch the steak and compare to the fleshy part of your palm below your thumb – rare feels soft, medium-rare is slightly firmer, medium is firm but springy.

Adjusting for Different Steak Cuts

Different cuts have varying thickness and fat content that affect cooking time.

Ribeye: Often 1–1.5 inches thick; follow the 1-inch times and add 1–2 minutes per side if thicker. The marbling helps keep it juicy even at medium.
New York Strip: Similar to ribeye but leaner; cook to medium-rare to avoid toughness.
Filet Mignon: Typically 1.5–2 inches thick. Sear 2 minutes per side over high heat, then move to indirect heat (turn off one burner) and cook until desired doneness – about 8–10 minutes total for medium-rare.
Sirloin: Usually thinner (3/4 inch); reduce time to 3–4 minutes per side for medium-rare.
T-Bone/Porterhouse: Has both a strip and filet; cook as you would a thick steak, but watch the leaner side to avoid overcooking.

Resting and Serving

Once the steak reaches your target temperature, transfer it to a cutting board and tent loosely with aluminum foil. Let it rest for 5 minutes – this allows the juices to redistribute throughout the meat. Do not skip this step, or you’ll lose flavorful juices when slicing. After resting, slice against the grain for maximum tenderness. For presentation, you can garnish with a pat of compound butter or fresh herbs. Serve immediately.

Pro Tips

For a better crust, pat the steak dry and season just before grilling – moisture is the enemy of searing.
Use a grill grate thermometer to know the exact surface temperature; built-in lid thermometers can be off by 50°F.
If your gas grill has hot spots, rotate the steak 180 degrees halfway through each side for even cooking.
Let the steak come to room temperature before grilling; a cold steak will cook unevenly and take longer.

Common Mistakes to Avoid

Flipping more than once – it prevents a good crust and can make the steak tough.
Using a fork to flip – piercing the meat releases juices and dries it out.
Skipping the rest – cutting into a steak immediately causes a puddle of lost juices.
Guessing doneness by color or time alone – always use a thermometer for accuracy.

FAQ

How long to grill a 2-inch steak on a gas grill?

For a 2-inch thick steak, sear 2 minutes per side over high heat, then move to indirect heat (one burner off) and cook 8–12 minutes more, flipping once, until internal temp reaches 130–135°F for medium-rare. Total time is about 12–16 minutes.

Should I grill steak with the lid open or closed?

Keep the lid closed as much as possible to maintain high heat and even cooking. Open only to flip or check temperature. For the initial sear, you can leave it open briefly to prevent steam, but close it to finish.

Do I need to oil the grates?

Yes, lightly oil the grates with a high-smoke-point oil (like canola or avocado) using a paper towel and tongs right before placing the steak. This prevents sticking and helps achieve a good sear.

The Bottom Line

Mastering steak on a gas grill comes down to temperature control and patience. Use a reliable instant-read thermometer, adjust times based on thickness, and always let the steak rest. With practice, you’ll consistently produce restaurant-quality steak at home.
