6 oz vs. 9 oz Flo’s Filet: Which Should You Order?
Both portions give you the same cut of steak; the main difference is serving size.
The 6 oz Flo’s Filet makes sense when you want a smaller steak dinner or plan to add a substantial side, salad or seafood pairing.
The 9 oz Flo’s Filet gives you about 50% more steak and may be a better fit when you want the filet itself to be the centerpiece of your meal.
One detail LongHorn’s menu material does not make clear is whether the listed 6 oz and 9 oz weights refer to pre-cooking or post-cooking weight. If you are tracking portions precisely, keep that limitation in mind.
What Is Flo’s Filet LongHorn Steakhouse?
Flo’s Filet is LongHorn Steakhouse’s signature center-cut filet and has been associated with the menu since the chain’s early years. LongHorn describes it as fresh rather than frozen and prepared to the guest’s preferred doneness.
The steak comes from the beef tenderloin, one of the least-worked muscles of the animal. That helps explain its characteristically soft texture without the heavy internal fat found in a ribeye.
For diners choosing between LongHorn steak cuts, the distinction is simple: Flo’s Filet focuses on tenderness, while ribeye delivers more marbling and richness.
Is Flo’s Filet a Filet Mignon?
Yes. Flo’s Filet is LongHorn’s center-cut tenderloin filet—the type of steak commonly known as filet mignon.
Filet mignon is cut from the tenderloin. It generally has less visible marbling than a ribeye but a noticeably softer bite, which is one reason filet can command a premium price despite its smaller portion size.
Why Is It Called Flo’s Filet?
Tasting Table reports that the steak was named after a former LongHorn server named Flo who was particularly fond of the cut.
LongHorn’s own promotional material supports the broader history, describing Flo’s Filet as a longtime guest favorite dating back to the restaurant’s early days. Because its current promotional material does not provide a detailed biography of Flo, it is better to treat the former-server explanation as reported history rather than expand it beyond the available evidence.
Flo’s Filet Calories and Nutrition
LongHorn menu materials list the 6 oz Flo’s Filet at 330 calories and the 9 oz portion at 450 calories, for the steak alone.For a fuller macro picture:

What Ingredients Are in Flo’s Filet?
At its core, Flo’s Filet is a center-cut beef tenderloin prepared with LongHorn’s steak seasoning.
LongHorn’s current public information does not disclose the complete proprietary seasoning formula. For that reason, online copycat recipes—particularly recipes labeled as “Prairie Dust”—should not automatically be treated as the official Flo’s Filet recipe.
How Is Flo’s Filet Seasoned?
LongHorn material and restaurant coverage point to signature Grill Seasoning as part of the steak’s preparation.
Seasoning is particularly noticeable on a filet because tenderloin has a milder natural beef flavor than heavily marbled cuts.
A Tasting Table review specifically highlighted the presence of LongHorn’s signature grill seasoning. The exact spice ratios remain proprietary, so they should not be guessed from copycat recipes.
Flo’s Filet Allergens, Gluten and Dietary Information
Allergen considerations apply to the whole order, not simply the beef.
Seasoning, sauces, toppings, sides and shared-kitchen preparation can affect the dietary profile of a meal. Anyone managing a serious food allergy should check LongHorn’s current allergen information and tell restaurant staff about the allergy when ordering.
Is Flo’s Filet Gluten-Free?
Do not assume that an entire Flo’s Filet meal is gluten-free simply because its main ingredient is steak.
Seasonings, toppings, sides and cross-contact in a shared kitchen can matter for people with celiac disease or wheat allergies. LongHorn’s current allergen guidance should therefore be checked when gluten avoidance is medically necessary.
Is Flo’s Filet Keto-Friendly?
The steak can potentially fit into a low-carbohydrate eating pattern, but “keto-friendly” is not an official LongHorn designation established by the research used for this guide.
Sides also matter. Vegetables create a very different carbohydrate profile from bread, potatoes or sugary drinks.
Because Flo’s Filet is beef, it is not vegetarian.
What Does Flo’s Filet Taste Like?
Tenderness is the defining characteristic of Flo’s Filet.
Compared with sirloin, the filet has a noticeably softer bite. Compared with ribeye, it contains less marbling, so its appeal comes more from tenderloin’s delicate texture than rich pockets of fat.
Reviewer experiences support that distinction, although opinions on overall flavor vary.
Tasting Table’s Flo’s Filet taste test described the medium-rare steak as juicy, heavily seasoned and properly cooked, while noting the relatively modest portion size.
A separate Eat This, Not That steak taste test found the filet notably tender but lighter in flavor than some other steak cuts.
Together, those experiences illustrate the trade-off: Flo’s Filet prioritizes softness and tenderness more than intense, fat-driven flavor.
What Do Reviewers and Diners Say About Flo’s Filet?
Tenderness is the most consistent positive theme across the research.
Opinions become more varied when it comes to flavor intensity. Some reviewers strongly favor the filet, while others prefer the richer character of more heavily marbled steaks.
Customer discussions also include occasional reports of filets arriving thinner or more cooked than expected. Those experiences should not be treated as universal, but they highlight an important point with a lean steak: doneness and restaurant execution can noticeably affect texture and moisture.
How Is Flo’s Filet Cooked at LongHorn?
LongHorn’s Grill Masters season and sear the filet to the guest’s requested doneness.
Some restaurant coverage describes a flat-top searing method, which is consistent with the browned exterior noted in taste tests. Exact restaurant cooking times and temperatures, however, are not established in the research used here.
That means copycat instructions should not be presented as LongHorn’s official cooking process.
What Doneness Works Well for Flo’s Filet?
Medium rare frequently appears in professional Flo’s Filet taste tests because that level of doneness can retain more of the tenderloin’s moisture and soft texture.
For example, Tasting Table tested the steak at medium rare and reported a tender result.
That does not make medium rare the only correct order. Steak doneness is ultimately a personal preference.
What Comes With Flo’s Filet Longhorn Steakhouse ?
LongHorn steak entrées have traditionally included a choice of side and hand-chopped salad, although exact choices and substitutions can vary by restaurant.
Your side selection can change the character of the meal considerably. A loaded potato creates a richer plate, while vegetables or salad keep the meal more focused on the steak.
Sides and Pairings to Consider With Flo’s Filet
A diner video included in our research showed a 9 oz Flo’s Filet served with grilled street corn, a loaded baked potato, side salad and horseradish on the side.
Other pairings to consider, depending on current availability, include:
- Loaded baked potato
- Broccoli or another vegetable side
- Hand-chopped salad
- Grilled street corn
- Horseradish on the side
These are pairing ideas rather than a ranking of the “best” LongHorn sides.
Flo’s Filet With Lobster Tail
Flo’s Filet has also been offered as a surf-and-turf combination with lobster tail.
LongHorn has offered a combination of a 6 oz Flo’s Filet and a 4 oz lobster tail. Check the official menu for your selected restaurant to confirm the current price and availability.
Because restaurant pricing and combinations can change, check your selected LongHorn location before ordering.
For diners who do not want a larger steak portion, the lobster combination provides another approach: tender filet plus seafood rather than simply moving from the 6 oz to the 9 oz steak.

Flo’s Filet vs. Other LongHorn Steaks
The right steak depends on what matters most to you: tenderness, marbling, richness, chew or value.
| Steak | Texture | Marbling | Main Character | Consider If You Prefer |
|---|---|---|---|---|
| Flo’s Filet® | Very tender | Lower | Mild, buttery | Tenderness |
| Ribeye* | Tender, juicy | High | Rich | Marbling and richness |
| Renegade Sirloin* | Firmer | Lower | Beef-forward | Leaner steak / value |
| New York Strip* | Firmer | Moderate | Robust | Traditional steak chew |
Flo’s Filet vs. Ribeye
The easiest way to understand this comparison is tenderness versus marbling.
Flo’s Filet is leaner and softer. Ribeye carries considerably more internal fat, giving it a richer and more fat-driven flavor.
If you dislike fatty sections in steak and prioritize a soft texture, the filet may suit you better. If marbling is one of your favorite parts of eating steak, ribeye offers a different experience.
Flo’s Filet vs. Renegade Sirloin
These two cuts can both appeal to diners who do not want excessive fat, but their textures are quite different.
Tenderloin gives Flo’s Filet its characteristic softness. Renegade Sirloin has a firmer, chewier steak texture and is typically the more value-oriented option.
Is Flo’s Filet Good and Worth Ordering?
Flo’s Filet is particularly suited to diners who want tenderness, a leaner steak profile and a soft filet texture.
Its trade-off is equally important: filet has less marbling than ribeye and is offered in relatively modest portions. Someone seeking intense fat-driven flavor or a much larger steak may prefer another cut.
For tenderness, Flo’s Filet is a strong option to consider. For heavier marbling and richness, a Ribeye or Outlaw Ribeye may better match that preference.
How to Order Flo’s Filet at LongHorn
Ordering comes down to five simple choices:
- Choose your portion — 6 oz for a smaller steak or 9 oz for more tenderloin.
- Choose your doneness — select the steak temperature you prefer.
- Build your plate — choose from the sides currently offered at your restaurant.
- Consider additions — a lobster tail or other eligible add-ons may be available.
- Check your local menu — confirm current pricing, combinations and availability.
