Plus, we’ll dive into the differences between grilling on a gas grill and a charcoal grill so that you can choose the best method for you.

Why Choose Filet Mignon?

Filet mignon is often considered the “king” of steaks because of its buttery tenderness and mild flavor. Cut from the tenderloin, it’s leaner than other steaks, with very little fat or connective tissue, making it an ideal choice for those who love tender, juicy meat without the chew.

For beginners, filet mignon is a great starting point because it’s more forgiving than other cuts. With the correct technique, achieving that perfect, juicy interior with a slightly crispy, caramelized exterior is easy.

Ingredients for Cooking Filet Mignon on a Gas Grill

Before we dive into the cooking process, let’s gather the ingredients you’ll need for a delicious, restaurant-quality filet mignon.

Ingredients:

– 2 (1.5–2-inch thick) filet mignon steaks

– 2 tablespoons olive oil (for brushing the steaks)

– Kosher salt (about 1 teaspoon per steak)

– Freshly ground black pepper (about 1 teaspoon per steak)

– Optional: Fresh garlic, rosemary, or thyme for added flavor

– Butter (for finishing, about 1 tablespoon per steak)

For a simple marinade (optional):

– 1/4 cup olive oil

– 1 tablespoon balsamic vinegar

– 1 teaspoon Dijon mustard

Recommended Tools for Grilling Filet Mignon

To ensure that your filet mignon is grilled to perfection, here are a few essential tools you should have on hand:

– Instant-read meat thermometer: This is essential for checking the steak’s internal temperature without cutting into it—a must-have for achieving your desired level of doneness.

– Tongs: Use long-handled tongs to handle the steaks without piercing them, which helps retain their juices.

– Grill brush: A clean grill is critical to getting those beautiful sear marks. Use a sturdy grill brush to remove residue from previous grilling sessions.

– Aluminum foil: Use this to tend your steaks after grilling to let them rest, allowing the juices to redistribute.

– Gas grill: The centerpiece for this recipe is that a gas grill provides controlled heat and a consistent cooking experience, which is perfect for beginners. You can refer to the ovens below:

• Weber Genesis II E-315 3-Burner Natural Gas Grill
• Char-Broil Performance 4-Burner Cart-Style Propane Gas Grill

Gas Grill vs. Charcoal Grill for Cooking Filet Mignon

If you’re wondering whether to use a gas or charcoal grill, it comes down to flavor preferences and convenience. Let’s break down the pros and cons of each method for cooking filet mignon.

Gas Grill:

• Pros: Gas grills are known for their ease and precision. You can control the temperature with a simple knob, making it easier to avoid overcooking. Gas grills heat up quickly (usually within 10-15 minutes), and there’s less cleanup involved.
• Cons: Gas grills don’t impart much smoky flavor to the meat. The taste will be clean and straightforward, relying more on your seasoning and the steak’s natural flavor.

Charcoal Grill:

• Pros: Charcoal grills deliver that coveted smoky flavor, which many steak lovers enjoy. If you prefer a deeper, more complex flavor, charcoal grilling is the way to go.
• Cons: Charcoal grills require more effort, from lighting the coals to maintaining the temperature. They also take longer to heat (about 30 minutes) and create more mess to clean afterward.

Our recommendation: Stick with a gas grill for beginners or those who want a more straightforward cooking experience. It’s easier to control, and you can still get a beautifully cooked filet mignon without worrying about flare-ups or fluctuating temperatures.

How to Cook Filet Mignon on a Gas Grill: Step-by-Step Instructions

Now that your ingredients and tools are ready, it’s time to fire up the grill! Follow these steps for perfectly grilled filet mignon every time.

1. Prep the Steaks

Take your steaks out of the refrigerator about 30 minutes before you grill. Let them come to room temperature—this helps the steaks cook evenly.

While the steaks rest, brush both sides with olive oil. Then, generously season with kosher salt and freshly ground black pepper. For added flavor, press a few sprigs of fresh rosemary or thyme onto the steaks or add a clove of crushed garlic.

If you’re using the optional marinade, combine the olive oil, balsamic vinegar, Dijon mustard, minced garlic, salt, and pepper in a small bowl. Place the steaks in a zip-top bag with the marinade, and refrigerate for at least 30 minutes (but no longer than 2 hours).

2. Preheat Your Gas Grill

Please turn on your gas grill and preheat it to high heat (about 450°F). Clean the grates with your grill brush to avoid any sticking. You want the grill to be nice and hot to create a good sear on the steaks.

Once the grill is preheated, lightly oil the grates using a cloth or paper towel soaked in olive oil to prevent the steaks from sticking.

3. Sear the Steaks

Place the filet mignon steaks directly over the heat source (high heat zone). Close the lid and sear the steaks on one side for about 4-5 minutes. You’re looking for a rich, golden-brown sear with distinct grill marks.

Use tongs to flip the steaks over and sear the other side for another 4-5 minutes.

4. Move to Indirect Heat

Once both sides are seared, move the steaks to a more excellent part of the grill (indirect heat zone). This will allow the inside to cook through without overcooking the exterior.

For medium-rare, grill the steaks for another 4-5 minutes. For medium, add 2-3 minutes per side. To ensure your steaks are perfectly cooked, use your instant-read thermometer:

– Rare: 120°F–125°F 3-4 minutes per side

– Medium-rare: 130°F–135°F 5 minutes per side

– Medium: 135°F–145°F 5-7 minutes per side

– Medium Well: 145° F – 155° F 7-9 minutes per side

– Well Done: Above 155° F 10 minutes per side

For filet mignon, medium-rare is the most popular doneness because it keeps the steak juicy and tender.

5. Rest the Steaks

Once your steaks reach the desired internal temperature, remove them from the grill. Place the steaks on a cutting board and cover them loosely with aluminum foil. Let them rest for 5-10 minutes to allow the juices to redistribute throughout the meat. This is an important step—don’t skip it!

6. Serve and Enjoy

After the resting period:

1. Slice the filet mignon steaks against the grain.
2. Serve them with your favorite sides, like roasted vegetables, mashed potatoes, or a fresh green salad.
3. Add butter to each steak for an extra touch of luxury before serving.

Quick Tips for Grilling Filet Mignon

– Don’t over-flip: Flip the steak only once during cooking to develop a proper sear and avoid drying the meat.

– Use a meat thermometer: This tool is a game-changer, helping you achieve the perfect level of doneness every time.

– Let the steak rest: Resting the steak lets the juices settle, giving you a more tender bite.
