Flo’s Filet LongHorn Steakhouse Signature Filet
Soft enough to cut with a butter knife and that is not marketing, it is anatomy. The LongHorn Flo’s Filet comes from the center of the beef tenderloin, the muscle that does almost no physical work in the animal. Zero exercise means zero tough fibers just the softest, most buttery bite on the entire Legendary Steaks menu. Made from USDA Choice beef, fresh and never frozen.
Every certified LongHorn Grill Master trained under the LongHorn Legendary Grill training program knows this cut is the least forgiving to overcook. Open-flame char grill builds the crust through the Maillard reaction. Finishing butter adds the gloss. And here is the insider move most guests miss: ask your server to add the Parmesan crust to your filet, Parmesan, provolone, garlic butter, and ranch baked right over the tenderloin. Not on the menu, but most kitchens will do it.

Cooking Temperatures for Flo’s Filet
Choosing the right doneness is the most important decision for this cut. The tenderloin has almost no intramuscular fat, its tenderness comes entirely from muscle fiber structure.Heat is the enemy: the longer it cooks, the tougher it gets.
| Doneness | Internal Temp | What It Looks Like | Best for Filet? |
|---|---|---|---|
| Rare | 120–125°F | Cool, bright red center | Not recommended |
| Medium Rare | 130–135°F | Warm red, extremely juicy | ⭐ Best Choice |
| Medium | 140–145°F | Warm pink center, still juicy | ⭐ Great Choice |
| Medium Well | 150–155°F | Slight pink, firmer | Acceptable |
| Well Done | 160°F+ | No pink, dry, tough | Not recommended |
Why Medium Rare Is Best for Flo’s Filet®
At Medium Rare (130-135°F), the muscle fibers stay relaxed, the steak stays juicy, and the LongHorn fire grill Maillard reaction creates a proper caramelized crust on the outside. Push past Medium and those fibers tighten, moisture escapes, and you lose exactly what makes the filet worth ordering. Every certified LongHorn Grill Master is trained specifically to nail this temperature under LongHorn Legendary Grill training program
