The Origin and Qualities of Filet Mignon


Filet mignon is one of the most prized cuts of beef, celebrated for its tenderness and delicate flavor. It comes from the tenderloin, a muscle along the spine that sees very little use during the animal’s life. Because this muscle does minimal work, the meat is incredibly tender with a fine grain and little connective tissue. Traditionally, filet mignon is lean compared to cuts like ribeye or strip steak, making it a go-to choice for those who want a melt-in-your-mouth texture with a mild beef flavor. When paired with the genetics of KC Cattle Company Wagyu cattle, the already luxurious American wagyu filet mignon is elevated into something extraordinary.

The Marbling and Rich Flavor of American Wagyu

What sets American Wagyu filet mignon apart is its marbling. Wagyu beef is famous for its intramuscular fat; those thin white lines that run through the meat. While a traditional filet mignon has very little fat, American Wagyu introduces a buttery richness that transforms the experience. The marbling melts during cooking, infusing the lean filet with juicy, decadent flavor. The result is a steak that remains fork-tender but gains a level of complexity and succulence rarely found in other filets. Each bite delivers both the tenderness filet mignon is known for and the indulgent flavor that Wagyu brings.

Wagyu Filet Mignon Is One of the Best Cuts

American Wagyu filet mignon is often described as the best of both worlds. From the tenderloin cut, you get unmatched softness and a silky mouthfeel. From the Wagyu genetics, you gain marbling that adds richness and depth of flavor. While many filets benefit from being wrapped in bacon or paired with heavy sauces, American Wagyu filet mignon shines on its own with just simple seasoning. This balance makes it a perfect steak for home cooks who want to serve something memorable without complicated preparation.


How to Cook American Wagyu Filet Mignon: Grilling Method

At KC Cattle Company, we offer American Wagyu Filet Mignon in 4 oz and 7 oz portions. Both sizes are perfect for grilling at home. Grilling is one of the best ways to highlight this steak’s natural flavors, creating a smoky crust while keeping the interior juicy and tender.


Step-by-Step Instructions:

  1. Prepare the steak: Let your American Wagyu filet mignon sit at room temperature for 30–45 minutes before cooking. Pat dry with a paper towel. Season generously with kosher salt and freshly cracked black pepper.

  2. Preheat the grill: Heat your grill to high (450–500°F). If using charcoal, set up a two-zone fire with one side hot and one cooler.

  3. Sear over high heat: Place the steak directly over the hottest part of the grill. For a 4 oz filet, grill for about 2 minutes per side. For a 7 oz filet, grill 3 minutes per side. Rotate halfway through for crosshatch grill marks.

  4. Move to indirect heat: Transfer the steaks to the cooler side of the grill and close the lid. Cook until the internal temperature reaches 125–130°F for medium-rare, 130–135°F for medium. Use a meat thermometer to check doneness.

  5. Rest before serving: Remove from the grill and let rest 5–10 minutes, tented loosely with foil. This allows the juices to redistribute for a perfect bite.

This grilling approach ensures a flavorful char on the outside and a tender, buttery center. It’s a simple and reliable method for anyone learning how to cook American Wagyu Filet Mignon at home.
