Few cuts of beef are as celebrated as filet mignon. Sourced from the tenderloin, a muscle that runs along the cow’s spine, this steak is revered for its unmatched tenderness. Because the muscle does little work, the meat remains exceptionally soft, with a fine grain and minimal connective tissue. Traditionally, Wagyu Filet Mignon is also one of the leanest cuts, making it a choice that delivers a subtle, delicate beef flavor. It’s a cut that has long been a centerpiece for special occasions, thanks to both its rarity and its fork-tender texture.

When you introduce Wagyu genetics to this cut, the experience changes dramatically. KC Cattle Company’s American Wagyu cattle produce beef with remarkable intramuscular marbling, which translates into richer flavor and juicier steaks. In a Wagyu Filet Mignon , this means the lean tenderness of the cut is enhanced with buttery fat that melts during cooking, ensuring every bite is flavorful and succulent. The result is a steak that maintains the filet’s signature tenderness while gaining the luxurious taste profile Wagyu is known for.

Comparing American Wagyu filet mignon to USDA Prime highlights just how unique this cut is. Prime beef is already excellent, with tenderness and some marbling, but American Wagyu consistently outpaces it in richness. USDA Prime filets tend to have a stronger beef-forward taste with a leaner profile, while American Wagyu filets offer a more buttery, melt-in-your-mouth experience. Thanks to higher marbling scores (often BMS 8+ versus Prime’s ~5), Wagyu has a creamier texture and juicier bite. Both are premium steaks, but Wagyu elevates the filet into a level of indulgence that few cuts can match. When you learn how to cook Wagyu Filet mignon, you'll never want to go back!
At KC Cattle Company, our American Wagyu Filet Mignon comes in 4 oz and 7 oz portions, both perfect for home cooking. One of the most reliable and flavorful methods is the pan-sear and oven finish. This technique gives you a beautiful golden-brown crust while cooking the steak gently to the perfect doneness inside.
Step-by-Step Instructions:
Preparation: Remove the steak from the refrigerator and let it come to room temperature for 30–45 minutes. Pat dry with paper towels. Season both sides generously with kosher salt and black pepper.
Preheat oven: Set your oven to 350°F.
Sear the filet: Heat a heavy skillet (cast iron is ideal) over high heat until very hot. Add a thin layer of high-smoke-point oil (like avocado oil). Place the filet in the skillet and sear for about 2 minutes per side for a 4 oz filet, or 3 minutes per side for a 7 oz filet, until a brown crust forms.
Transfer to oven: After searing, place the skillet directly into the preheated oven. Cook for about 5–8 minutes for the 4 oz filet and 8–12 minutes for the 7 oz filet, depending on thickness. Use a meat thermometer and remove the steak when it reaches 125–130°F for medium-rare or 130–135°F for medium.
Rest the steak: Place the filet on a plate or cutting board and loosely tent with foil. Let rest for 5–10 minutes before serving. This ensures juices redistribute for maximum tenderness and flavor.
This method is especially forgiving for home cooks and highlights why many chefs recommend it when teaching how to cook Wagyu Filet Mignon.
