How To Cook Filet Mignon On The Grill | Perfect Medium-Rare

Sear filet mignon fast over high heat, then finish over gentler heat to 130–135°F for tender, pink, juicy slices.

Filet mignon is the “treat yourself” steak. It’s lean, soft, and mild, so it needs a plan on the grill. Get the sear wrong and it tastes flat. Push it too far and it dries out fast.

This walkthrough keeps it simple: buy the right cut, season it smart, set up your grill for two heat zones, then cook by internal temp. You’ll get a browned crust, a warm center, and a steak that still feels buttery when you cut it.

What Makes Filet Mignon Tricky On A Grill

Filet comes from the tenderloin, which does less work than most muscles. That’s why it’s tender. It’s also why it has less fat to “self-baste” while it cooks.

On a grill, high heat can brown the outside before the center warms through. Lower heat can warm the center but leave the surface pale. The fix is two-zone cooking: a hot side for crust, a cooler side to finish.

One more thing: filet is often thick. Thickness is your friend because it buys you time to build color without blowing past your target internal temp.

Choosing Filet Mignon For The Grill

Start at the store. A better cut makes the cooking part easier.

Pick The Right Thickness

Look for steaks that are 1.5 to 2 inches thick. Thinner filets can still work, but you’ll have a tighter window between browned and overdone.

Look For Even Shape

A squat, even “barrel” shape cooks more evenly than a tapered piece. If you see one end much thinner, plan to position that thinner end away from the hottest spot.

Consider Bacon-Wrapped Vs. Plain

Bacon-wrapped filets can add fat and flavor, but they change timing. Bacon insulates the sides, slows cooking a bit, and can flare if fat drips. If you go bacon-wrapped, keep a cooler zone ready.

Plan On 6–8 Ounces Per Person

Most filets are rich enough at 6–8 ounces, especially with sides. Bigger steaks cook a bit longer, so factor that into your fire management.

Seasoning That Fits Filet Mignon

Filet tastes clean and beefy. Heavy rubs can bury that. Salt is the main move, then a few supporting players.

Simple Salt Timing

You’ve got two good options:

• Right before grilling: Salt and pepper, then straight to the grill. It’s fast and still tasty.
• 40–60 minutes before grilling: Salt the steaks and leave them on a rack (or a plate) in the fridge. This gives you better surface drying for browning.

If you salt and then get interrupted, don’t leave raw steak sitting out for hours. Keep it chilled until you’re close to cooking time.

Pepper And A Little Oil

Black pepper is classic. Add a thin coat of a neutral oil on the steak (not a puddle). This helps seasoning stick and supports browning.

Optional Finish Flavor

Since filet is lean, a finishing fat pays off: a pat of butter, a spoon of compound butter, or a drizzle of olive oil right as it rests. You’ll taste the difference in the first bite.

How To Cook Filet Mignon On The Grill Step By Step

This is the core method: hot sear, gentle finish, then rest. It works on gas, charcoal, and pellet grills.

Step 1: Set Up Two Heat Zones

Gas grill: Preheat with the lid closed. Keep one side on high for searing. Set the other side to medium-low (or even off) for finishing.

Charcoal grill: Bank hot coals on one side. Leave the other side with little to no coal for indirect heat. Put the lid on and let the grate heat well.

Pellet grill: Pellet grills sear differently. If yours has a direct-flame or sear zone, use it. If not, you can cook at a higher temp to start, then drop down or move steaks to a cooler edge to finish.

Step 2: Preheat Until The Grates Are Truly Hot

Don’t rush this. A hot grate gives you better browning and cleaner release. On most grills, 10–15 minutes of preheating with the lid down gets you there.

Step 3: Pat Dry And Season

Right before the steak hits the grill, blot the surface with paper towels. Season with salt and pepper. If you like garlic powder, keep it light.

Step 4: Sear Over High Heat

Place filets on the hot side. Keep the lid closed between flips so you hold heat.

• Sear 2–3 minutes with the lid closed.
• Flip and sear 2–3 minutes more.
• If you want crosshatch marks, rotate the steak 45 degrees halfway through each sear side.

Use tongs. No fork. You want the juices staying inside the steak, not on the grate.

Step 5: Move To The Cooler Zone And Finish By Temperature

After the crust looks deep brown, move filets to the cooler side and close the lid. Now you’re cooking the center gently.

Insert an instant-read thermometer into the thickest part from the side, aiming for the center. Keep the probe away from the grate and any pockets of fat around the edges.

Pull the steaks a few degrees before your final target since the temp rises while resting:

• Rare: pull at 120–125°F, finish 125–130°F
• Medium-rare: pull at 125–130°F, finish 130–135°F
• Medium: pull at 135–140°F, finish 140–145°F

Step 6: Rest Before Slicing

Rest filets 5–10 minutes on a plate or board. Resting keeps juices from spilling out when you cut.

Food safety guidance for whole cuts of beef lists 145°F with a 3-minute rest as a safe minimum for steaks and roasts. You can read the chart on Safe Minimum Internal Temperatures.

Step 7: Slice Or Serve Whole

Filet mignon is tender enough to serve whole. If you slice, cut across the grain. Finish with a pinch of flaky salt or a small pat of butter.

Table 1: Grill Timing And Doneness Cheat Sheet

Use this as a quick read while you grill. Times assume 1.5–2 inch filets and a hot sear zone. Your grill and steak thickness can shift timing, so treat time as a range and temp as the deciding factor.

Goal	What To Do	When To Pull
Deep crust, rare center	Sear 2–3 min per side, finish indirect with lid closed	120–125°F
Classic medium-rare	Sear 2–3 min per side, finish indirect 3–7 min	125–130°F
Medium with pink center	Sear 2–3 min per side, finish indirect 5–10 min	135–140°F
Thinner filet (1–1.25 in)	Sear 2 min per side, finish indirect briefly	Use same pull temps
Bacon-wrapped filet	Sear, then finish indirect longer; watch for flare-ups	Use same pull temps
Extra-thick filet (2+ in)	Sear, then finish indirect longer with lid closed	Use same pull temps
Strong smoke flavor	Add wood chunk to coals, finish indirect with lid closed	Use same pull temps
Cleaner grill marks	Place on hot grates, don’t move for first 2 minutes	Pull by temp, not marks

Thermometer Tips That Save The Steak

If you only change one habit, change this: cook filet mignon by internal temp, not by minutes. Minutes can’t see inside your steak.

Where To Probe

Go in from the side, straight toward the center, so the tip lands in the thickest middle. If you go in from the top, it’s easy to overshoot and touch the grate-side hot zone, which reads higher than the true center.

When To Start Checking

Start checking right after you move to the cooler zone. Check again every 1–2 minutes near the end. The temp can rise fast in the last stretch.

Rest Time Matters For Safety, Too

Resting isn’t just about juiciness. Food safety guidance pairs a minimum rest time with whole-cut temperatures. The CDC’s prevention page includes safe internal temps and a 3-minute rest note for whole cuts of beef. See CDC food safety prevention guidance.

Common Grill Problems And Fixes

Even good grills throw curveballs. Here are quick fixes you can use on the spot.

No Crust, Just Gray Meat

• Your grates weren’t hot enough. Preheat longer with the lid closed.
• The steak surface was damp. Pat dry right before it hits the grill.
• Too much marinade. For filet, keep it dry and simple.

Burnt Outside, Cool Middle

• Heat was too high for too long. Shorten the sear and finish indirect.
• Steak was extra thick. Use the cooler zone longer with the lid closed.
• Sugar in the seasoning. Skip sweet rubs for filet.

Overcooked Center

• You waited for a “done” look. Pull by thermometer reading.
• You didn’t account for carryover heat. Pull 5°F early.
• You sliced right away. Rest 5–10 minutes.

Flare-Ups And Bitter Taste

• Too much oil or dripping bacon fat. Use a thin oil coat and keep a cooler zone ready.
• Grease build-up on grates. Clean grates before you start.
• Open lid feeding flames. Move to indirect and close the lid until it settles.

Table 2: Main Takeaways For Better Grilled Filet

Moment	What To Do	Why It Works
Before grilling	Pick 1.5–2 inch steaks and pat them dry	More control on browning and doneness
Seasoning	Salt + pepper, keep rubs light	Filet stays clean and beef-forward
Grill setup	Two zones: hot sear side and cooler finish side	Crust plus gentle center cooking
Searing	2–3 minutes per side with lid closed between flips	Better heat retention and browning
Finishing	Cook indirect to 125–130°F for medium-rare pull temp	Center hits 130–135°F after resting
Resting	Rest 5–10 minutes before slicing	Juices stay put, slices look moist
Serving	Finish with butter or flaky salt	Adds richness to a lean cut

Side Pairings That Fit Filet Mignon

Filet is mild, so sides can carry more personality. Keep the plate balanced: one crisp veggie, one starchy comfort, one bright bite.

• Crisp: grilled asparagus, charred broccoli, simple side salad
• Comfort: roasted potatoes, mashed potatoes, grilled corn
• Bright: lemony greens, chimichurri-style herb sauce, quick pickled onions

If you’re serving wine, a medium-bodied red pairs well, but a good sparkling drink works too. Filet isn’t a “fight me” steak. It’s calm and clean.

Last Checks Before You Serve

Give the steak a final thermometer check after resting. If it landed a touch under your target, set it back on the cooler zone for 1–2 minutes with the lid closed, then rest 2 minutes again.

If it went a bit over, don’t panic. Slice and add a finishing fat. Butter or olive oil helps the mouthfeel, and a pinch of salt wakes up the flavor.

Once you’ve grilled filet mignon this way a couple of times, you’ll feel the rhythm: hot sear, gentle finish, rest, then eat while it’s still warm and silky.
