How Long to Grill a 1.5-Inch Ribeye
About 12-15 minutes total using a two-zone fire at 450-500°F, pulling the steak at 125°F internal for medium-rare. At this thickness, a straight direct-heat sear alone tends to overcook the outside before the center catches up, so the two-zone method below gets you a better result than searing the whole time.
What You Need
- Ribeye steak, about 1.5 inches thick
- Neutral oil or a splash of Worcestershire sauce
- Kosher salt and coarse black pepper
- Instant-read thermometer
How to Grill a 1.5-Inch Ribeye Step by Step
Bring to Room Temp and Season
Take the ribeye out of the fridge and let it sit at room temperature for 30-45 minutes. Pat it dry with paper towels, then coat it lightly with oil (or a thin layer of Worcestershire sauce) and season generously with kosher salt and black pepper, or a smoked beef rub if you want more depth.
Set Up a Two-Zone Fire
Preheat your grill to 450-500°F with a hot, direct side and a cooler, indirect side (on gas, this means leaving some burners off or on low; on charcoal, bank the coals to one side).
Sear Over Direct Heat
Place the ribeye over direct heat and grill with the lid closed for about 2-3 minutes per side, just long enough to develop a deep brown crust.
Finish Over Indirect Heat (if needed)
If the steak hasn’t reached your target internal temperature after searing both sides, move it to the indirect side and close the lid to let it finish gently, checking temperature every couple of minutes.
Rest Before Slicing
Pull the ribeye about 5°F below your target and rest it 5-10 minutes before slicing or serving.
1.5-Inch Ribeye Time and Temp Chart by Doneness
| Doneness | Pull Temp | Approx. Total Time |
|---|---|---|
| Rare | 115-120°F | 10-12 min |
| Medium-Rare | 125°F | 12-15 min |
| Medium | 135-140°F | 15-18 min |
| Medium-Well | 145-150°F | 18-20 min |
How to Grill Ribeye Without Drying It Out
- Don’t cook past medium. Ribeye’s fat renders beautifully up to medium, but push it further and you lose a lot of that juiciness.
- Use a thermometer, not a clock. Thickness, starting temperature, and grill output all vary — the only reliable way to hit your target is to check internal temperature directly.
- Use the two-zone method on anything over an inch thick. Direct heat the whole time tends to overcook the outer half-inch before the center is done.
- Rest it properly. Cutting in immediately lets juices run out instead of redistributing through the meat.
- Don’t press down on the steak. Pressing squeezes out juice and won’t speed up cooking — it just dries the meat.
What Is the 3-3-3 Rule for Ribeye?
Roughly 3 minutes per side over direct heat, then 3 minutes indirect or resting. For a 1.5-inch ribeye, that direct-sear portion is close to accurate, but you’ll usually need more than 3 minutes on the indirect side to hit medium-rare all the way through — treat it as a starting point and finish by temperature. For a thinner cut where 3-3-3 tracks more closely, see our propane grill ribeye guide. If you’d rather skip direct grilling altogether and reverse-sear this thickness on a smoker, our smoked ribeye temperature guide covers that method.
FAQ
How long to cook a 1.5-inch thick ribeye on the grill? About 12-15 minutes total using a two-zone fire at 450-500°F for medium-rare, longer for more doneness.
How do I cook a 1.5-inch steak on a grill? Sear over direct heat for a crust, then move to indirect heat to finish coming up to temperature — this avoids overcooking the outside before the center catches up.
What is the 3-3-3 rule for grilling steak? Roughly 3 minutes per side over direct heat, then 3 minutes indirect or resting — a rough starting point, not an exact formula for every thickness.
How do you grill a ribeye without drying it out? Use a two-zone fire, stop at medium or below, check temperature with a thermometer instead of guessing by time, and rest the steak properly before slicing.
