How Long to Grill Steak by Thickness and Doneness (Chart)
A 1-inch (2.5 cm) steak over direct high heat takes about 8–10 minutes total, flipped once halfway, to reach a medium-rare 130–135°F (54–57°C). The safe minimum for a whole-muscle steak is 145°F (63°C) plus a 3-minute rest — anything cooked to a lower temperature is a personal doneness choice below that USDA floor, not a food-safety guarantee.
Grilling time depends heavily on thickness, how hot the grill actually runs, whether the steak came straight from the fridge or sat out first, and the specific cut — a lean flank steak behaves differently on the grate than a fatty ribeye. Timing gets you close; a thermometer gets you exact.
For food safety, the USDA safe minimum internal temperature for whole cuts of beef, pork, lamb and veal is 145°F (63°C), followed by a 3-minute rest, per the USDA FSIS safe minimum internal temperature chart. That standard applies to whole-muscle steaks because bacteria mostly live on the exterior, which searing on a hot grill destroys; ground beef is different and needs 160°F (71°C) throughout since grinding mixes surface bacteria into the interior.
Grilling Time Chart by Thickness and Doneness
| Thickness | Rare (125°F) | Medium-Rare (130–135°F) | Medium (140–145°F) | Timer (medium-rare) |
|---|---|---|---|---|
| ¾ inch (2 cm) | 5–6 min total | 6–7 min total | 7–8 min total | |
| 1 inch (2.5 cm) | 7–8 min total | 8–10 min total | 10–11 min total | |
| 1½ inch (3.8 cm) | 10–11 min total | 12–14 min total | 14–16 min total |
Times assume direct high heat (roughly 450–500°F / 230–260°C grate temperature) and one flip at the halfway point. A cooler grill or a fattier cut like ribeye may run a minute or two longer than a lean strip steak at the same thickness.
Doneness Temperature Reference
Pull the steak a few degrees before the target, since carryover heat during the rest adds roughly 5°F. Rare sits around 120–125°F off the grill, medium-rare 128–130°F, medium 138–140°F, medium-well 148–150°F, and well-done 158°F and up. Only medium (145°F) and above meets the USDA safe minimum without relying on the surface-searing exception that applies specifically to intact, unpierced steaks.
Reverse Sear for Thick Steaks
For steaks 1½ inches (3.8 cm) or thicker, cooking indirect (off direct flame) at around 250°F (120°C) until the center reaches about 15°F below target, then finishing over direct high heat for 60–90 seconds per side to sear, gives a more even edge-to-edge doneness than direct heat alone. Direct-only grilling on a thick steak tends to overcook the outer inch before the center catches up.
From the Fridge vs. Room Temperature
A cold steak straight from the refrigerator grills unevenly — the exterior can hit target temperature while the center is still noticeably cooler. Letting a steak sit out for 20–30 minutes before grilling (no longer, per USDA guidance on the 40–140°F danger zone) evens out the cook and can shave a minute or two off the total time in the chart above.
Bone-In vs. Boneless Steaks
A bone-in steak, like a T-bone or a tomahawk ribeye, takes slightly longer near the bone since bone conducts heat differently than muscle, and the meat right against it often reads a few degrees cooler than the rest of the steak. Check the thermometer away from the bone for the most accurate reading, and expect bone-in cuts to need roughly 10–15% more time than an equivalent boneless steak of the same thickness.
Checking Doneness Without a Thermometer
The hand-press method — comparing the steak's firmness to the fleshy pad below your thumb as you touch different fingers to it — gives a rough estimate but is far less reliable than an instant-read thermometer, especially across different cuts and thicknesses. Since steak doneness spans just a 20–30°F window between rare and well-done, a thermometer inserted horizontally into the thickest part is the only method that reliably distinguishes them.
Salting and Marinating Before Grilling
Salting a steak generously 40–60 minutes before grilling, rather than right before it hits the grate, gives the salt time to draw out surface moisture and then reabsorb back into the meat, seasoning it more evenly and helping the crust form faster once it's on the grill. Salting just a few minutes ahead has the opposite effect, pulling moisture to the surface without enough time to reabsorb, which can leave the exterior steamy instead of seared.
Marinades change flavor more than they change texture on a naturally tender steak like ribeye or strip, and a long marinade — over 2 hours — mostly affects the outer few millimeters regardless of how long it sits. Tougher, leaner cuts like flank or skirt steak benefit more from an acidic marinade's tenderizing effect, but even then 4–8 hours is usually enough; much longer can start to turn the exterior mushy rather than more tender.
Common Mistakes
- Flipping the steak repeatedly instead of once or twice, which prevents the deep crust that a hot grate needs uninterrupted contact time to build.
- Pulling the steak at the exact target temperature instead of a few degrees early, which lets carryover heat push it past the intended doneness during the rest.
- Skipping the rest entirely, which sends the juices running out onto the cutting board the moment the steak is sliced.
- Using the same timing for a thin cut and a thick one, when thickness — not weight — is what actually drives grilling time.
- Grilling a cold, straight-from-the-fridge steak on a grill that isn't fully preheated, which stretches the sear time and dries the exterior before the center catches up.
- Testing temperature by cutting into the steak instead of using a thermometer, which lets juices run out before the steak has even finished resting.
- Ignoring how much a cut's fat content changes cooking speed, since a well-marbled ribeye behaves differently on the grate than a lean, uniform sirloin of the same thickness.
Quick Answers
How long do you grill a 1-inch steak for medium-rare?
About 8–10 minutes total over direct high heat, flipped once, pulled around 128–130°F to land at 130–135°F after a short rest. A thermometer in the thickest part is the only way to confirm it precisely.
Is medium-rare steak safe to eat?
Medium-rare (130–135°F) is below the USDA's 145°F safe minimum for whole-muscle beef, so it is a doneness choice rather than a food-safety guarantee. The lower risk compared with undercooked ground beef comes from searing the exterior, where surface bacteria live, on an intact cut — that logic does not apply to ground beef burgers, which need to reach 160°F throughout.
Should you grill steak straight from the fridge?
Letting it sit out 20–30 minutes first grills more evenly than a cold steak straight from the refrigerator, but USDA guidance caps safe room-temperature time at about 2 hours in the 40–140°F danger zone, so don't leave it out longer than needed. See the full grill temperature and time chart for how steak compares with other grilled foods.
How long should a grilled steak rest?
3–5 minutes loosely tented with foil is enough for most steaks to reabsorb their juices without cooling off significantly, and it also accounts for the carryover cooking that continues after the steak leaves the grate.
Does a thicker steak need a hotter or cooler grill?
Thicker steaks generally do better starting over slightly lower, indirect heat before a final direct sear, since full direct heat the whole time tends to burn the outside before a thick center reaches target temperature. Thinner steaks under an inch handle full direct high heat for their entire cook without that risk, since there's much less distance for heat to travel before reaching the center.
