BBQ Filet Mignon Recipe Grill: Smoky Char With Herb-Infused Richness

Filet mignon on the grill deserves a method that honors its natural tenderness and rich flavor. This approach ensures a perfectly charred exterior while maintaining a buttery, juicy interior that melts with every bite.

The key lies in high heat and precise timing. A simple herb-infused rub enhances the beef without overpowering its natural depth. The result is a steak with a smoky crust and a tender center that rivals any steakhouse offering.

Grilling at the right temperature ensures even cooking and that signature char. The herb rub adds subtle layers of aroma that complement the beef’s richness, creating a dish that’s both elegant and approachable.

Serve this with your favorite sides for a meal that feels special but remains effortlessly achievable. The technique is straightforward, yet the results are anything but ordinary.

Ingredients for Bbq Filet Mignon Recipe Grill

Center-cut filet mignon plus a bold herb rub deliver that signature smoky char.

The steak quality is non-negotiable here. USDA Prime or Choice grade filet mignon ensures the buttery texture this dish demands. Look for cuts at least 1.5 inches thick—thinner steaks overcook too easily on high heat. Whole Foods or a trusted butcher are ideal sources, but most supermarkets carry acceptable options if you inspect the marbling closely.

No fresh rosemary? Dried at half the amount works in the rub, though the aroma won’t be as vibrant. Short on garlic powder? Onion powder adds a similar depth. The butter can be salted if that’s what you have (just ease up on the kosher salt). For a smokier profile, swap the olive oil for avocado oil—its higher smoke point handles the grill heat better.

Steaks can rest at room temperature for 30-45 minutes before grilling—don’t leave them out longer. Leftover cooked steak keeps in the fridge for 3-4 days and reheats beautifully in a cast-iron skillet. The herb rub components store in a cool, dark place for up to 6 months.

Step-by-Step Instructions for BBQ Filet Mignon

Master the grill with precision timing and herb-infused basting for restaurant-quality results at home.

Step 1: Season and Temper the Filet Mignon

Pat the filet mignon steaks dry with paper towels to ensure a perfect sear. Combine the kosher salt, freshly ground black pepper, garlic powder, dried rosemary, and dried thyme in a small bowl. Rub this mixture evenly over all surfaces of the filet mignon steaks, pressing gently to adhere.

Let the seasoned filet mignon steaks sit at room temperature for 30-45 minutes before grilling. This step is crucial for even cooking throughout the thick cut. The surface should develop a slightly tacky texture as the salt begins to penetrate.

Step 2: Prepare the Grill for High-Heat Searing

Preheat your grill to high heat (about 450-500°F). Use the vegetable oil to lightly coat the grates with a folded paper towel and long tongs. This prevents sticking and ensures beautiful grill marks on the filet mignon steaks.

Clean the grates thoroughly before oiling. You want to see white-hot coals or hear a sharp sizzle when you flick water onto the grates. The high heat is essential for developing that smoky char on the exterior while maintaining a tender interior.

Step 3: Sear and Baste with Herb-Infused Butter

Place the filet mignon steaks on the grill and sear undisturbed for 4-5 minutes on each side for medium-rare. Resist the urge to move them—this allows a proper crust to form. Add the olive oil to the steaks during the last minute of searing on each side to enhance browning.

Reduce heat to medium and add the unsalted butter, smashed fresh garlic cloves, and fresh rosemary sprigs to the grill near the steaks. Tilt the filet mignon steaks slightly and spoon the melted butter mixture over them continuously for 2-3 minutes, basting all surfaces. The fresh rosemary sprigs will infuse the butter with aromatic oils as they char slightly.

Step 4: Rest and Serve for Maximum Tenderness

Transfer the filet mignon steaks to a warm platter when they reach an internal temperature of 125-130°F for medium-rare. The meat will continue cooking as it rests, rising to 130-135°F internally. Cover loosely with foil to retain heat.

Let the filet mignon steaks rest for 10-15 minutes before serving. This allows the juices to redistribute throughout the meat, ensuring each bite is moist and flavorful. The final temperature should read 130-135°F when tested with an instant-read thermometer inserted into the thickest part.
