How to Cook Filet Mignon on the Grill: A Step-by-Step Guide

Filet mignon is one of the most sought-after cuts of beef, prized for its buttery texture and mild flavor. This tender cut comes from the small end of the beef tenderloin, making it one of the leanest yet most luxurious steaks available. Grilling filet mignon allows you to create a restaurant-quality dish at home, highlighting its natural flavors with a beautiful sear and juicy interior.

In this guide, we’ll walk you through every step of cooking filet mignon on the grill, from choosing the right cut to achieving the perfect level of doneness. Whether you’re a grilling novice or an experienced BBQ enthusiast, this method ensures a mouthwatering result every time.

Selecting the Right Filet Mignon

The quality of your steak significantly impacts the final outcome, so it’s crucial to choose the best cut. Here’s what to consider:

1. Grade of Meat

• USDA Prime: Highest quality, featuring excellent marbling and tenderness.
• USDA Choice: Slightly less marbling than Prime but still a great option.
• Wagyu or Grass-Fed: Offers a rich, buttery taste with exceptional tenderness.

2. Thickness Matters

• Look for steaks that are 1.5 to 2 inches thick to ensure even cooking.
• Thinner cuts tend to cook too quickly, making it difficult to achieve a good sear while keeping the inside juicy.

3. Bone-in vs. Boneless

• Boneless filet mignon is the most common and easiest to grill.
• Bone-in filet mignon (sometimes called “tournedos”) provides extra flavor but requires careful grilling to avoid uneven cooking.

Preparing the Filet Mignon

Before grilling, proper preparation ensures maximum flavor and tenderness.

1. Bring Steak to Room Temperature

• Remove the filet mignon from the fridge 30-45 minutes before cooking.
• Letting it come to room temperature helps it cook evenly.

2. Pat the Steak Dry

• Use paper towels to remove excess moisture.
• This helps create a better sear on the grill.

3. Seasoning Options

A high-quality filet mignon doesn’t need much, but here are two excellent seasoning methods:

Simple Seasoning

• Generously season both sides with kosher salt and freshly ground black pepper.
• Lightly coat with olive oil to prevent sticking.

Enhanced Flavoring

• Rub with minced garlic and rosemary for extra aroma.
• Brush with a thin layer of butter or steak rub for added depth.
• Let the seasoning sit for 15 minutes before grilling.

Prepping the Grill

Grilling filet mignon requires high heat to create a crusty exterior while maintaining a tender interior.

Gas Grill

• Preheat the grill to 450-500°F.
• Use both direct and indirect heat zones for precise cooking.

Charcoal Grill

• Set up a two-zone fire (one side hot, one side cooler).
• Use lump charcoal for the best flavor.

Pellet Grill

• Preheat to 450°F.
• Choose oak, hickory, or mesquite pellets for a smoky depth.

Pro Tip:

• Clean and oil the grates before grilling to prevent sticking and ensure proper searing.

Grilling Process: Achieving the Perfect Filet Mignon

The key to a perfect filet mignon is using both direct and indirect heat. Here’s how:

1. Sear Over Direct High Heat

• Place steaks directly over the hottest part of the grill.
• Sear for 2-3 minutes per side, flipping once, until a golden-brown crust forms.

2. Move to Indirect Heat

• Transfer steaks to the cooler side of the grill.
• Close the lid and cook until desired doneness is reached.

3. Use a Meat Thermometer

Insert a thermometer into the thickest part of the steak to ensure accuracy:

Doneness	Internal Temp	Approx. Cook Time (Indirect Heat)
Rare	120-125°F	3-5 minutes
Medium Rare	130-135°F	5-7 minutes
Medium	140-145°F	7-9 minutes
Medium Well	150-155°F	9-11 minutes

4. Resting the Steak

• Remove the filet from the grill and tent loosely with foil.
• Let it rest for 5-10 minutes to allow the juices to redistribute.

Serving Suggestions

A perfectly grilled filet mignon deserves equally delicious accompaniments.

Enhance with Butter or Sauce

• Top with garlic herb butter for extra richness.
• Serve with red wine reduction or peppercorn sauce.

Best Side Dishes

• Grilled asparagus or roasted Brussels sprouts for a healthy touch.
• Creamy mashed potatoes or truffle fries for indulgence.
• Garlic butter mushrooms to complement the steak’s savory profile.

Wine Pairing

• Cabernet Sauvignon: Bold and rich, pairs well with filet’s tenderness.
• Pinot Noir: Lighter, fruitier option for a delicate pairing.

Conclusion

Cooking filet mignon on the grill is a rewarding experience that results in an ultra-tender, flavorful steak. By selecting a high-quality cut, using proper seasoning, and mastering the grilling technique, you can achieve steakhouse-level perfection at home. Whether you enjoy it simply with salt and pepper or elevate it with compound butter and gourmet sides, this method ensures a juicy, mouthwatering bite every time.
