Grilling a filet mignon requires a two-zone fire so you can sear and then cook gently. This method ensures you get a perfect crust without drying out the tender meat. If you have ever wondered how to cook a filet mignon on the grill, this guide will walk you through every step.
Filet mignon is lean and delicate. It lacks the fat of ribeye or strip steak, so you need to treat it right. Overcooking ruins it. Underseasoning leaves it bland. But with the right technique, you can achieve restaurant-quality results at home.
How To Cook A Filet Mignon On The Grill
Choose The Right Cut
Start with the best meat you can find. Look for filets that are at least 1.5 inches thick. Thinner cuts cook too fast and are hard to sear without overcooking.
- Select USDA Prime or Choice grade for better marbling.
- Ask your butcher for center-cut filets, which are more uniform.
- Check that the meat is bright red with minimal browning.
- Aim for 8 to 10 ounces per serving for a satisfying portion.
Prepare The Steak
Take the filets out of the fridge 30 to 45 minutes before grilling. This lets them come to room temperature, which helps them cook evenly.
Pat the steaks dry with paper towels. Moisture is the enemy of a good sear. Dry surfaces brown better.
Season generously with kosher salt and fresh cracked black pepper. Do not add oil to the steak; oil the grill grates instead. Let the salt sit for at least 15 minutes so it can penetrate the meat.
Set Up A Two-Zone Fire
A two-zone fire is critical for grilling filet mignon. You need a hot side for searing and a cooler side for gentle cooking.
- For a charcoal grill, pile all coals on one side of the grill. Leave the other side empty.
- For a gas grill, turn one burner to high and the other to medium-low or low.
- Close the lid and let the grill preheat for 10 to 15 minutes.
- The hot zone should reach 450°F to 550°F. The cool zone should be around 300°F.
Sear The Filets
Oil the grill grates using a paper towel dipped in vegetable oil and held with tongs. Do this just before placing the steaks.
Place the filets on the hot side of the grill. Let them sear undisturbed for 2 to 3 minutes. Do not move them around; you want a deep crust.
Flip the steaks with tongs, not a fork. A fork pierces the meat and lets juices escape. Sear the second side for another 2 to 3 minutes.
If you want grill marks, rotate the steaks 45 degrees after 1.5 minutes on each side. But a solid sear is more important than crosshatch patterns.
Move To Indirect Heat
After searing, transfer the filets to the cool side of the grill. This is where the gentle cooking happens. Close the lid to trap heat.
Cook to your desired doneness. Use an instant-read thermometer for accuracy. Insert it into the thickest part of the steak, away from bone.
- Rare: 120°F to 125°F (remove at 118°F)
- Medium-rare: 130°F to 135°F (remove at 128°F)
- Medium: 140°F to 145°F (remove at 138°F)
- Medium-well: 150°F to 155°F (remove at 148°F)
- Well-done: 160°F+ (not recommended for filet)
For medium-rare, expect about 4 to 6 minutes on the cool side after searing. Thicker steaks need more time. Thinner ones need less.
Add Butter And Aromatics (Optional)
During the last minute of cooking, you can add a pat of butter on top of each steak. Toss in a sprig of thyme or rosemary and a crushed garlic clove. Let the butter melt and baste the steak with a spoon.
This step adds richness and flavor. It is not required, but it elevates the final dish.
Rest The Steak
Remove the filets from the grill when they are 5°F below your target temperature. Carryover cooking will raise the internal temp by 5°F to 10°F while resting.
Place the steaks on a cutting board or plate. Tent loosely with aluminum foil. Let them rest for 5 to 10 minutes. Do not skip this step; resting allows juices to redistribute throughout the meat.
If you cut into the steak too early, the juices will run out and leave you with dry meat.
Slice And Serve
After resting, slice the filet against the grain. This shortens the muscle fibers and makes each bite tender. Serve immediately with your favorite sides.
Filet mignon pairs well with roasted vegetables, mashed potatoes, or a simple salad. A red wine sauce or chimichurri also complements the mild flavor.
Common Mistakes To Avoid
Grilling Cold Steaks
Never put a cold steak directly on the grill. The center will stay raw while the outside burns. Always let the meat warm up first.
Using Too Much Oil
Oil the grates, not the steak. Excess oil on the meat can cause flare-ups and a greasy crust. A light coating on the grates is enough.
Flipping Too Often
Let the steak sear without moving it. Flipping repeatedly prevents a good crust from forming. One flip per side is ideal.
Cutting Into The Steak To Check Doneness
Do not slice the steak to see if it is done. This releases juices and ruins the texture. Use a thermometer instead.
Overcooking
Filet mignon is best at medium-rare or rare. Cooking it beyond medium dries it out and wastes its tenderness. Keep a close eye on the temperature.
Best Seasonings For Filet Mignon
Simple seasoning works best for this cut. The meat has a delicate flavor that can be overwhelmed by heavy rubs.
- Salt and pepper: The classic choice. Use coarse kosher salt and freshly ground black pepper.
- Garlic powder: Adds a subtle savory note without burning.
- Herb butter: Mix softened butter with minced garlic, parsley, and thyme. Add a pat after grilling.
- Steak seasoning blends: Look for blends without sugar, which can burn on the grill.
Avoid marinades for filet mignon. They can make the meat mushy and mask its natural flavor. Dry seasoning is all you need.
Grill Temperature Tips
Managing heat is key when you learn how to cook a filet mignon on the grill. Here are some practical tips:
- Use a grill thermometer to monitor the hot and cool zones.
- If the grill is too hot, the outside will char before the inside cooks.
- If the grill is too cool, the steak will steam instead of searing.
- Adjust the vents on a charcoal grill to control airflow and temperature.
- For gas grills, keep the lid closed as much as possible to retain heat.
How To Tell When Filet Mignon Is Done
Using a thermometer is the most reliable method. But if you do not have one, you can use the finger test. Compare the firmness of the steak to the fleshy part of your palm below your thumb.
- Rare: Soft and squishy, like your palm when your hand is relaxed.
- Medium-rare: Slightly firmer, like your palm when you touch your thumb and index finger together.
- Medium: Firmer still, like your palm when you touch your thumb and middle finger.
- Well-done: Very firm, like your palm when you touch your thumb and pinky.
This method takes practice. A thermometer is more precise and recommended for beginners.
Frequently Asked Questions
Can I grill frozen filet mignon?
It is not recommended. Frozen steaks cook unevenly and are hard to sear properly. Thaw them in the refrigerator overnight before grilling.
Should I use a charcoal or gas grill for filet mignon?
Both work well. Charcoal gives a smokier flavor, while gas offers easier temperature control. Choose based on your preference.
How long should I let filet mignon rest after grilling?
Rest for 5 to 10 minutes. Thicker steaks need closer to 10 minutes. This allows the juices to settle and the internal temperature to stabilize.
Can I grill filet mignon without a two-zone fire?
You can, but it is harder to get a good sear without overcooking. A two-zone fire gives you more control and better results.
What sides go best with grilled filet mignon?
Try roasted asparagus, garlic mashed potatoes, grilled mushrooms, or a simple arugula salad with lemon vinaigrette.
