What Is Flo's Filet?

Named after one of LongHorn's original grill masters, Flo's Filet® is cut from the center of the beef tenderloin. Because this muscle does not bear weight, it contains very little connective tissue, making it the most tender cut of beef available.

At LongHorn, this filet mignon is prepared plain fire-grilled with a light signature dusting, keeping it extremely low in fat and high in lean protein. It is offered in 6-ounce and 9-ounce portions, serving as a lower-calorie premium alternative to the heavy marbling of ribeyes or porterhouses.

How It's Prepared

How It's Prepared The kitchen staff at Flo's Filet begins by cutting steaks from the center of premium beef tenderloin, ensuring consistent thickness and quality across each portion. They dust the raw meat with the restaurant's signature seasoning blend, a combination of kosher salt, cracked black pepper, and house spices that builds a flavorful crust. The seasoned cuts move to a high-heat grill where they cook to your requested temperature, typically 2 to 3 minutes per side for medium-rare. The Longhorn beef's marbling renders during this brief cooking window, basting the meat from within. Staff pull each steak at precise doneness and rest it for several minutes before plating.

What to Pair It With

What to Pair It With Longhorn Flo's filet pairs well with steamed fresh asparagus, which complements the richness of the beef without overwhelming it. A simple side salad with vinaigrette adds brightness and helps cut through the meat's fat content. For beverages, a chardonnay enhances the savory notes, while iced tea offers a refreshing alternative that cleanses the palate between bites. The citrus or herbal notes in either drink balance the protein's density, making the combination satisfying without leaving you feeling overstuffed.

Is It Worth the Price?

Is It Worth the Price? At $24.79 for a 6 oz. center-cut tenderloin, Flo's Filet price lands below most upscale steakhouses, which charge $38 to $52 for comparable cuts. The beef grades Prime, and the center-cut designation ensures minimal fat waste. You'll spend roughly $4.13 per ounce versus $6 to $9 at fine dining establishments. The trade-off is straightforward: you handle cooking yourself rather than paying for kitchen labor and ambiance. If you own a reliable cast-iron skillet and a meat thermometer, this represents solid value for quality protein.
