For a 1.5-inch steak over a properly preheated hot grill (about 450–500°F), plan on roughly 9–12 minutes total for most common doneness levels, but always confirm with a meat thermometer for accuracy.

Quick Scoop: Core Timing Guide

These times assume:

  • Steak about 1.5 inches thick
  • Grill at high heat (around 450–500°F)
  • Steak brought close to room temp and patted dry

Use this as a starting point and adjust slightly for your grill and steak type.

Simple Step-by-Step

  1. Preheat your grill
    • High heat, about 450–500°F, for 15–20 minutes to get the grates ripping hot.
  1. Prep the steak
    • Bring to near room temp, pat dry, season with salt and pepper or your favorite rub.
  1. Sear over direct heat
    • Place steak over direct high heat.
    • Grill using the timing from the table, flipping once halfway (e.g., about 5–6 minutes per side for medium-rare).
  1. Check temperature, not just the clock
    • Use an instant-read thermometer in the thickest part.
    • Pull the steak off the grill a few degrees below your target; carryover heat will finish it (e.g., remove around 125–130°F for medium-rare).
  1. Rest the steak
    • Let it rest 5–10 minutes so the juices redistribute before slicing.

Two-Zone / Reverse-Sear Option (For Extra Control)

If you want a bit more control or are nervous about overcooking:

  • Sear: 2–3 minutes per side over direct high heat to build crust.
  • Finish: Move to indirect heat, close the lid, and cook until the steak reaches your desired internal temperature (usually a few extra minutes, depending on your grill).
  • Rest: Same 5–10 minute rest at the end.

Quick Example

If you’re grilling a 1.5-inch ribeye and aiming for medium-rare tonight:

  • Preheat to ~500°F.
  • Grill about 5–6 minutes per side over direct heat.
  • Start temp-checking around the 8–9 minute mark; pull at roughly 130°F and rest for 8–10 minutes.

TL;DR: For a 1.5-inch steak, most people get a good medium-rare at roughly 10–12 minutes total on a hot grill, but let a thermometer make the final call.
