How Long To Grill a Tenderloin Steak | Time & Temp for Perfect Doneness

Grill a 1-inch tenderloin steak at 450°F–500°F for about 10–14 minutes total for medium-rare, pulling it from the heat at 125°F to allow the final 5–10°F of carryover cooking.

The clock matters less than the thermometer. Tenderloin is so lean that a minute past medium-rare turns it dry, so the real answer to how long to grill a tenderloin steak is: until it hits the right internal number. The ranges below work for gas and charcoal grills with 1-inch to 1.5-inch steaks, and the two main methods — direct heat and reverse sear — change the timing completely.

The Temperature Targets That Decide Doneness

Pull the steak off the grill 5°F–10°F below your target temperature, because residual heat continues cooking the meat during the rest. The table below captures the final serving temperatures and the correct removal points.

Anything past medium dries out tenderloin fast. Medium-rare is the sweet spot, and pulling the steak at the lower end of the range is the single safest move for a first-timer.

Direct-Heat Grilling: The Standard Method

Direct heat is the simplest route for individual steaks up to 1.5 inches thick. The grill grate needs to hit 400°F–500°F, and the lid stays closed between flips to trap heat.

Preheat the grill for 15 minutes, brush the grates clean, and oil them with a wadded paper towel dipped in vegetable oil. Season the steaks generously with salt and black pepper — but wait until after grilling to add fresh pepper if using high heat, because pepper burns and turns bitter on a hot surface. Pat the meat dry with paper towels first; moisture on the surface kills the crust.

Place the steak over the hottest part of the fire. Cook 5–6 minutes on the first side with the lid down, then flip and cook 3–4 minutes on the second side. For a deeper char with a sauce glaze, flip once more and cook another 2–3 minutes. Total grilling time for medium-rare at 500°F is 10–14 minutes, depending on thickness.

The the steak releases easily from the grates when the crust is set. If it sticks, it needs another minute. Insert the instant-read thermometer through the side of the steak into the center. When it reads 120°F–125°F, move the steak to a plate.

Reverse-Sear Method: For Thicker Cuts and More Control

Steaks over 1.5 inches thick benefit from the two-zone reverse sear, which cooks the interior gently before blasting the exterior with high heat. This method takes about 45 minutes total but produces a more even doneness from edge to edge.

Set up the grill with a hot zone and a cool zone. Aim for 275°F–300°F on the indirect side. Season the steak the same way, then place it on the cool side with the lid closed. Cook until the internal temperature reaches 115°F — roughly 25 minutes for a 1.5-inch steak. Remove the steak and rest it for 15–20 minutes, during which the temperature drops slightly and the internal gradient evens out. Then sear it over the direct-heat side for 1–2 minutes per side, watching closely because the high heat can roll flames. The final internal temperature should land at 120°F–125°F before resting.

Do not walk away during the sear phase. The combination of rendered fat and high heat produces flare-ups that can torch the surface in seconds. If you see sustained flames, move the steak back to the cool side and reduce the burner temperature before trying again.

Pre-Grill Steps That Change How Long To Grill a Tenderloin Steak

Cold meat throws off every timing estimate. A steak straight from the fridge needs extra grill time on the outside to reach the same internal temperature, which means the exterior overcooks before the center catches up.

Let the steak sit on the counter for 30–60 minutes before it hits the grate. Pat it dry with paper towels right before seasoning — damp seasoning steams rather than sears. A generous coating of kosher salt helps form the crust, but black pepper is best applied after cooking on high-heat grills to avoid bitterness.

Resting and Serving: The Final 15 Minutes

The steak is not done when it comes off the grill. The carryover heat inside the meat raises the temperature another 3°F–10°F over the next 8–20 minutes, and the resting time lets the juices redistribute instead of spilling onto the cutting board.

Tent the steak loosely with foil — tight foil traps steam and softens the crust. After 10–15 minutes, top with a pat of herb butter or a dollop of caramelized shallot butter, then slice into half-inch rounds. An electric knife or sharp carving knife produces clean slices without shredding the tender meat.

Finish With the Right Procedure

Grill tenderloin steaks by temperature, not the clock. Use an instant-read thermometer inserted sideways into the thickest part of the steak. Pull direct-heat steaks at 120°F–125°F for medium-rare; pull reverse-seared steaks at the same target after the final sear. Rest them for at least 10 minutes, add the butter finish, and slice across the grain. That sequence will produce a tender, juicy steak every time, whether you are cooking for two or for the whole grill.
