Grilling a filet mignon on a gas grill requires careful attention to direct and indirect heat zones. If you have been wondering how to cook a filet mignon on a gas grill, you have come to the right place. This cut is known for its tenderness, and with the right technique, you can achieve a perfect sear and a juicy interior every time.
Filet mignon comes from the tenderloin, which is a muscle that does very little work. This makes it incredibly soft, but also lean. Because it lacks fat, you need to be careful not to overcook it. A gas grill gives you precise control over temperature, which is ideal for this delicate steak.
In this guide, we will walk through every step. You will learn how to prep the meat, set up your grill, and cook the filet to your preferred doneness. We will also cover resting and slicing, plus answer common questions.
Why Choose A Gas Grill For Filet Mignon
A gas grill heats up quickly and maintains a steady temperature. This is important for filet mignon because you want a hot sear without burning the outside. You can easily create two zones: one for direct high heat and one for indirect lower heat.
Gas grills also allow you to control flare-ups. Filet mignon has less fat than ribeye or strip steak, so flare-ups are less common, but still possible. With a gas grill, you can adjust the burners instantly.
Another benefit is convenience. You do not have to wait for charcoal to ash over. Turn on the gas, preheat, and you are ready to cook in about 10 minutes.
Selecting The Right Filet Mignon
Start with a good cut. Look for filets that are about 1.5 to 2 inches thick. Thinner steaks cook too fast and are harder to get a good sear without overcooking.
Choose steaks with even marbling. While filet is lean, some have small streaks of fat that add flavor. Also check for a bright red color and avoid any with gray or brown spots.
If you can, buy USDA Prime or Choice grade. Prime has more marbling and will be more forgiving on the grill. Choice is still good but may be slightly less tender.
Preparing The Steak For The Grill
Take the filet out of the fridge 30 to 45 minutes before cooking. This lets it come to room temperature, which helps it cook more evenly. Do not leave it out longer than that for food safety.
Pat the steak dry with paper towels. Moisture on the surface creates steam, which prevents a good sear. Dry meat browns better.
Season generously with kosher salt and freshly ground black pepper. You can add other spices like garlic powder or rosemary, but keep it simple. Salt is the most important ingredient. Apply it just before grilling or up to an hour ahead.
Some people like to coat the steak with a little oil. This can help the seasoning stick and prevent sticking to the grill. Use a high smoke point oil like canola or avocado oil.
Setting Up Your Gas Grill
Clean the grill grates with a wire brush. Residue from previous cooks can cause sticking and off flavors. Then preheat the grill on high with the lid closed for 10 to 15 minutes.
After preheating, create two heat zones. Turn one burner to high and the other to medium-low or off. This gives you a hot side for searing and a cooler side for finishing.
If your grill has three burners, set the left and right on high and the middle on low. This gives you more room to move the steak if needed. The goal is to have a surface temperature around 500°F to 600°F on the hot side.
How To Cook A Filet Mignon On A Gas Grill
Now we get to the main event. Follow these steps for a perfect filet.
Step 1: Sear The Steak
Place the filet on the hot side of the grill. Let it sear without moving for 3 to 4 minutes. You want a dark crust, not just a light brown. Resist the urge to flip early.
Use tongs to flip the steak. Do not use a fork because piercing the meat releases juices. Sear the second side for another 3 to 4 minutes.
If the steak has a fat cap on the side, use tongs to hold it upright and sear the edge for about 1 minute. This renders the fat and adds flavor.
Step 2: Move To Indirect Heat
After searing both sides, move the filet to the cooler side of the grill. Close the lid. This allows the steak to cook through without burning the outside.
The internal temperature will rise slowly. Use a meat thermometer to check doneness. Insert it into the thickest part of the steak, away from the bone if there is one.
For medium-rare, aim for 130°F to 135°F. For medium, go to 140°F to 145°F. Remember that the temperature will rise about 5 degrees while resting.
Step 3: Check Doneness
Here are approximate cooking times for a 1.5-inch filet on indirect heat:
- Rare: 2 to 3 minutes (125°F final)
- Medium-rare: 4 to 6 minutes (130°F to 135°F)
- Medium: 6 to 8 minutes (140°F to 145°F)
- Medium-well: 8 to 10 minutes (150°F to 155°F)
- Well done: 10 to 12 minutes (160°F+)
These times are estimates. Always use a thermometer for accuracy. Filet mignon is best at medium-rare or medium. Well done will be dry and tough.
Step 4: Rest The Steak
Remove the filet from the grill when it is about 5 degrees below your target. Place it on a cutting board or plate. Tent loosely with foil.
Let it rest for 5 to 10 minutes. This allows the juices to redistribute throughout the meat. If you cut too soon, the juices will run out and the steak will be dry.
During resting, you can add a pat of butter on top. This adds richness and a glossy finish. Some people like to add fresh herbs like thyme or rosemary at this point.
Step 5: Slice And Serve
After resting, slice the filet against the grain. This shortens the muscle fibers and makes each bite more tender. Filet mignon is usually served whole, but you can slice it for presentation.
Serve immediately. You can pair it with a simple salad, roasted vegetables, or mashed potatoes. A red wine sauce or chimichurri also works well.
Tips For Perfect Results Every Time
Here are some extra tips to help you succeed.
Use A Meat Thermometer
Do not rely on touch or time alone. A digital instant-read thermometer is the best tool for accuracy. Insert it from the side to get a reading from the center.
Do Not Overcrowd The Grill
Leave space between steaks. If you crowd them, they will steam instead of sear. Cook in batches if needed.
Let The Grill Recover Heat
After searing one batch, close the lid and let the grill come back up to temperature before adding more steaks. This ensures a consistent sear.
Consider Reverse Searing
For thicker filets (2 inches or more), try reverse searing. Cook the steak on the indirect side first until it reaches about 110°F, then sear on high heat for 1 to 2 minutes per side. This gives an even cook from edge to edge.
Common Mistakes To Avoid
Even experienced cooks make mistakes. Here are the most common ones.
- Not preheating the grill long enough. A cold grill will not sear properly.
- Flipping the steak too often. Let it sit to develop a crust.
- Using a fork to flip. This pierces the meat and loses juices.
- Overcooking. Filet mignon is lean and dries out quickly.
- Skipping the rest. This is one of the most important steps.
Frequently Asked Questions
Can I Cook Filet Mignon From Frozen On A Gas Grill?
It is not recommended. Frozen steak will cook unevenly and may burn on the outside while still raw inside. Thaw it in the refrigerator overnight for best results.
What Is The Best Temperature For Grilling Filet Mignon?
Aim for a grill surface temperature of 500°F to 600°F for searing. After searing, use indirect heat at around 350°F to finish cooking.
How Do I Know When Filet Mignon Is Done Without A Thermometer?
You can use the finger test, but it is less reliable. For medium-rare, the steak should feel like the fleshy part of your palm when you touch your thumb to your ring finger. A thermometer is much more accurate.
Should I Oil The Steak Or The Grill Grates?
Both can work. Lightly oiling the steak helps seasoning stick. Oiling the grates with a paper towel dipped in oil prevents sticking. Do not use too much oil to avoid flare-ups.
Can I Marinate Filet Mignon Before Grilling?
You can, but it is not necessary. Filet mignon is tender enough without a marinade. A simple salt and pepper rub is often best. If you do marinate, keep it short (30 minutes to 2 hours) to avoid breaking down the meat too much.
Conclusion
Grilling a filet mignon on a gas grill is straightforward when you follow the right steps. Start with a good cut, let it come to room temperature, and season simply. Set up your grill with direct and indirect heat zones. Sear the steak hard, then finish on the cooler side. Always use a thermometer and let the steak rest before slicing.
With practice, you will be able to cook a perfect filet every time. The key is patience and attention to detail. Do not rush the sear or skip the rest. Your guests will thank you.
Now you have all the information you need to cook a filet mignon on a gas grill. Fire up the grill, grab your tongs, and enjoy a restaurant-quality steak at home.
