How To Cook Filet On Grill
Grilling filets gives them smoky char marks, and the key is managing heat zones so the inside cooks evenly. If you want to know how to cook filet on grill like a steakhouse pro, you need a hot side for searing and a cooler side for finishing. This guide walks you through prep, temps, timing, and resting so your filet comes out tender every time.
What You Need Before You Start
Filet mignon is lean and tender, but that also means it dries out fast. A little setup goes a long way.
- Two filets, about 6 to 8 ounces each, 1.5 to 2 inches thick
- Kosher salt and coarse black pepper
- High smoke point oil like avocado or canola
- Instant read meat thermometer
- Tongs and a clean plate
- Aluminum foil for resting
You also want a grill with two zones. That means all the coals on one side, or one burner on high and the other off.
How To Cook Filet On Grill
This is the core method. Follow these steps in order and you will get a crusty outside and a juicy middle.
Step 1: Prep And Temper The Filets
Pull the filets from the fridge 30 to 40 minutes before cooking. Cold meat cooks unevenly.
Pat them completely dry with paper towels. Moisture steams the surface and blocks browning.
Season both sides with salt and pepper. Be generous. You can also tie a piece of butcher twine around the side to keep the shape round, but its optional.
Step 2: Set Up Your Heat Zones
For a gas grill, preheat one side to high heat and leave the other side off. Close the lid for 10 minutes.
For charcoal, light a chimney of briquettes. Once they ash over, pour them on one half of the grill. Put the grate on and let it heat for 5 minutes.
You want the hot side around 450 to 500°F. The cool side should sit near 225 to 300°F.
Step 3: Oil The Grates
Fold a paper towel, dip it in oil, and rub it over the hot grates with tongs. Do this right before the filets go on.
A clean, oiled grate prevents sticking. It also helps those char marks form cleanly.
Step 4: Sear Over Direct Heat
Place the filets on the hot side. Leave them alone for 2 to 3 minutes.
Flip once with tongs. Never press down with a spatula. You will squeeze out the juices.
Sear the second side for another 2 to 3 minutes. You should see a dark brown crust.
Step 5: Move To Indirect Heat
Slide the filets to the cool side of the grill. Close the lid.
Cook for 4 to 6 minutes, then check the internal temp. This is where even cooking happens.
Target temps for doneness:
- Rare: 120 to 125°F
- Medium rare: 130 to 135°F
- Medium: 140 to 145°F
- Medium well: 150 to 155°F
Pull them 5 degrees before your target. The temp will rise while resting.
Step 6: Rest The Meat
Move the filets to a plate and tent them loosely with foil. Let them rest for 5 to 8 minutes.
Resting lets the juices redistribute. Skip this and the juice runs out on the cutting board.
Step 7: Serve
Slice against the grain if you cut them at all. A whole filet on the plate looks better anyway.
Add a pat of butter or a spoon of garlic herb sauce on top while they rest. It melts into the crust.
Common Mistakes To Avoid
Most bad filets come from a few repeat errors. Watch out for these.
- Grilling cold meat straight from the fridge
- Using too high heat the whole time and burning the outside
- Not drying the surface before seasoning
- Flipping more then once
- Cutting into the filet to check doneness instead of using a thermometer
- Skipping the rest
Tips For Better Flavor
Filet is mild, so it takes on whatever you put on it. Try these simple upgrades.
- Rub with a little Dijon mustard before seasoning
- Add chopped rosemary or thyme to the oil
- Finish with flaky sea salt after resting
- Grill a few halved shallots on the cool side and serve them on top
You can also baste the filets with melted butter and garlic during the last minute on the hot side. Just watch for flare ups.
How Long To Grill Filet
Timing depends on thickness and grill temp. As a rough guide for a 2 inch filet:
- 2 to 3 minutes per side on direct high heat
- 4 to 6 minutes on indirect heat for medium rare
- 5 to 8 minutes on indirect heat for medium
Always trust your thermometer over the clock. Every grill runs a bit different.
Final Thoughts
Grilling filet is not hard once you understand the two zone setup. Sear it hot, finish it slow, and let it rest. That is the whole game.
Practice once or twice and you will nail the timing for your own grill. Soon you will be cooking filets that beat most steakhouse plates, and you did it in your own backyard.
