Perfect Pan-Seared Filet Mignon with Roasted Garlic Butter

Master the art of the steakhouse experience at home with this foolproof recipe for Pan-Seared Filet Mignon with Garlic Butter. The filet mignon is prized for its melt-in-your-mouth tenderness, and when paired with a rich, aromatic garlic-herb butter, it becomes a gourmet masterpiece. This method uses a high-heat sear to lock in juices, finished with a classic butter-basting technique that ensures every bite is infused with savory flavor.

Ingredients for the Ultimate Filet Mignon

• 2 Filet Mignon Steaks: (6-8 oz each, at least 1.5 to 2 inches thick)
• Kosher Salt and Coarse Black Pepper: Be generous for a perfect crust.
• 2 Tablespoons Avocado Oil: Or any high-smoke point oil like grapeseed.
• 3 Tablespoons Unsalted Butter: High-quality European butter recommended.
• 3 Cloves Fresh Garlic: Smashed to release oils.
• Fresh Herbs: 2 sprigs of rosemary and 3 sprigs of thyme.

Step-by-Step Cooking Instructions

1. Preparation is Key

Remove your steaks from the refrigerator 30 to 45 minutes before cooking. This allows them to reach room temperature, ensuring even cooking. Pro tip: Use a paper towel to pat the steaks completely dry on all sides. Moisture is the enemy of a golden-brown crust.

2. Season Generously

Season the steaks liberally with salt and pepper on all sides, including the edges. Press the seasoning into the meat so it adheres during the sear.

3. The High-Heat Sear

Place a heavy-bottomed cast iron skillet over medium-high heat. Add the oil and wait until it begins to shimmer and just slightly smoke. Carefully place the steaks in the pan. Sear undisturbed for 3-4 minutes until a deep brown crust forms. Flip the steaks using tongs.

4. The Garlic Butter Baste

Immediately after flipping, reduce the heat to medium. Add the butter, smashed garlic cloves, rosemary, and thyme to the pan. Once the butter melts and begins to foam, tilt the pan slightly and use a large spoon to continuously pour the hot, flavored butter over the steaks for the remaining 3-4 minutes of cooking.

5. Monitor Temperature

For a standard 2-inch steak, this timing typically yields a perfect Medium-Rare (internal temperature of 130°F to 135°F). For thicker cuts, you may need to transfer the entire skillet to a 400°F oven for 2-5 additional minutes.

6. The Rest

Transfer the steaks to a cutting board or warm plate. Pour any remaining pan juices over them and let them rest for at least 5–10 minutes. This allows the muscle fibers to relax and reabsorb the juices.

Filet Mignon Fact-Check

Understanding your meat makes you a better cook. Here are a few essential facts about this premium cut:

• The Cut: Filet Mignon comes from the smaller end of the tenderloin, a muscle that does very little work, which is why it is so tender.
• The Name: In French, “Filet” means a thick slice and “Mignon” means dainty or cute.
• Leanness: It is one of the leanest cuts of beef, containing less marbling than a Ribeye, which is why the addition of garlic butter is essential for flavor and moisture.
• The Sear: The “Maillard Reaction” is the chemical process that occurs between amino acids and reducing sugars when searing, giving the steak its distinctive savory crust.
