What Is Flo’s Filet at LongHorn Steakhouse?
Flo’s Filet® is a tender center-cut filet served at LongHorn Steakhouse.
The filet is coated with LongHorn’s signature Grill Seasoning and seared to develop its familiar steakhouse crust and buttery-tasting beef flavor.
Unlike heavily marbled steaks such as ribeye, filet is prized primarily for tenderness. Filet comes from the tenderloin, one of the naturally tender sections of beef.
That makes LongHorn Flo’s Filet especially popular among guests who want a softer steak with less visible fat.
It is also recognized as a LongHorn Steakhouse Specialty, meaning it is one of the restaurant’s signature menu items.
For customers who frequently search for the most tender steak at LongHorn Steakhouse, Flo’s Filet is one of the strongest options to consider.
LongHorn Flo’s Filet 6 oz vs 9 oz
LongHorn offers Flo’s Filet in two primary portion sizes.
Choosing between the 6 oz Flo’s Filet and 9 oz Flo’s Filet generally depends on your appetite, calorie preference, protein needs, and budget.
| Feature | 6 oz Flo’s Filet | 9 oz Flo’s Filet |
|---|---|---|
| Portion Size | 6 oz | 9 oz |
| Price | $26.99 | $32.49 |
| Calories | 330 | 450 |
| Total Fat | 15 g | 19 g |
| Saturated Fat | 5 g | 7 g |
| Protein | 37 g | 56 g |
| Sodium | 330 mg | 480 mg |
| Carbohydrates | 2 g | 3 g |
| Dietary Fiber | 0 g | 0 g |
The 6 oz Flo’s Filet is ideal for diners who prefer a smaller steak and want additional room for a side, salad, appetizer, or dessert.
The 9 oz Flo’s Filet offers 50% more steak by weight and significantly more protein.
The price difference between the two portions is approximately $5.50 based on the menu information reviewed.
For diners focused on value and protein, the 9 oz steak may offer the better upgrade.
For guests watching calories or portion size, the 6 oz version may be more suitable.
LongHorn Flo’s Filet Calories
One of the most common questions people ask is:
How many calories are in LongHorn Flo’s Filet?
The answer depends on the steak size.
6 oz Flo’s Filet Calories
The 6 oz Flo’s Filet contains approximately 330 calories.
It provides a substantial amount of protein while staying lower in calories than many larger steak cuts.
9 oz Flo’s Filet Calories
The 9 oz Flo’s Filet contains approximately 450 calories.
Although the portion is 50% larger than the 6 oz steak, it adds only about 120 calories to the steak itself.
However, those calorie totals apply to the steak portion.
Your complete meal can contain considerably more calories after adding salad dressing, bread, potatoes, fries, soup, mac and cheese, or other sides.
LongHorn indicates that a choice of side and salad may contribute approximately 220 to 860 additional calories, depending on what you select.

These numbers make Flo’s Filet nutrition particularly attractive to diners searching for a high-protein steak with relatively few carbohydrates.
Still, remember that restaurant recipes and portions can change, and preparation differences may slightly affect nutrition values.
How Much Protein Is in Flo’s Filet?
Flo’s Filet is a particularly protein-rich menu option.
| Flo’s Filet Portion | Protein |
|---|---|
| 6 oz | 37 g |
| 9 oz | 56 g |
The 6 oz Flo’s Filet provides 37 grams of protein, while the larger 9 oz serving provides 56 grams.
The 9 oz steak therefore delivers approximately 19 additional grams of protein compared with the smaller portion.
For diners looking for high-protein LongHorn Steakhouse meals, Flo’s Filet is one option worth considering.
However, a larger serving is not automatically better for everyone.
Someone who plans to eat bread, soup, salad, sides, or dessert may prefer the smaller 6 oz portion.
How Many Carbs Are in Flo’s Filet?
Flo’s Filet itself is naturally very low in carbohydrates.
The 6 oz Flo’s Filet contains approximately 2 grams of carbohydrates, while the 9 oz steak contains around 3 grams.
| Size | Carbohydrates |
|---|---|
| 6 oz Flo’s Filet | 2 g |
| 9 oz Flo’s Filet | 3 g |
Both steaks also contain essentially no dietary fiber.
That makes the steak itself suitable for many diners searching for low-carb options at LongHorn Steakhouse.
However, the complete meal may not remain low-carb.
Sides such as:
- Loaded Baked Potato
- Sweet Potato
- Seasoned French Fries
- Seasoned Rice
- Steakhouse Mac & Cheese
can significantly increase the carbohydrate count.
For a lower-carb meal, consider pairing the filet with vegetables such as broccoli or asparagus.
LongHorn Flo’s Filet Ingredients
LongHorn does not publicly provide the full proprietary recipe for Flo’s Filet or the exact ingredient percentages used in its signature Grill Seasoning.
Based on the menu description, the main components include a center-cut beef filet and LongHorn’s signature steak seasoning.
| Component | Ingredient Information |
|---|---|
| Main Ingredient | Center-cut beef filet |
| Seasoning | LongHorn signature Grill Seasoning |
| Preparation | Seasoned and seared/grilled |
| Full Seasoning Recipe | Proprietary |
| Exact Recipe | Not publicly disclosed |
Customers should avoid relying on unofficial online recipes when they need precise ingredient information for medical or allergy reasons.
Seasoning blends can also change over time.
If you have a serious food allergy, it is always best to speak directly with the restaurant before placing your order.
LongHorn Flo’s Filet Allergen Information
Allergen information is especially important for diners with food sensitivities.
The standalone Flo’s Filet is not generally identified as containing several major allergens in LongHorn’s allergen information.
However, the steak is prepared on restaurant cooking equipment, including a grill that may also be used for other foods.
This creates the possibility of cross-contact.
| Allergen | Flo’s Filet |
|---|---|
| Milk / Dairy | Not listed as a primary allergen in standalone steak |
| Egg | Not listed as a primary allergen |
| Wheat | Not listed as a primary allergen |
| Soy | Not listed as a primary allergen |
| Peanut | Not listed as a primary allergen |
| Tree Nuts | Not listed as a primary allergen |
| Fish | Not listed as a primary allergen |
| Shellfish | Not listed as a primary allergen |
| Sesame | Not listed as a primary allergen |
| Cross-Contact Risk | Possible due to shared kitchen/grill |
This does not mean the steak can be guaranteed allergen-free.
Restaurants prepare many foods in shared cooking environments.
Guests with severe allergies should inform the server before ordering so the restaurant can explain current preparation practices.
Is LongHorn Flo’s Filet Gluten-Free?
Flo’s Filet is commonly included among LongHorn’s gluten-sensitive menu options.
However, “gluten-sensitive” and “certified gluten-free” are not the same thing.
The steak may be made without intentionally adding gluten-containing ingredients, but LongHorn Steakhouse does not operate completely gluten-free kitchens.
Shared preparation surfaces, grills, utensils, and cooking areas may create cross-contact.
Therefore, the safest way to describe Flo’s Filet is:
Flo’s Filet can be a gluten-sensitive option, but it is not guaranteed to be completely gluten-free.
People with celiac disease or serious wheat allergies should discuss their needs with restaurant staff before ordering.
What Comes With Flo’s Filet?
Flo’s Filet can be customized with a choice of side and salad.
The exact options may vary by location, but typical selections include several vegetables, potatoes, rice, salads, soups, and premium sides.

- Seasoned French Fries
- Mashed Potatoes

| Premium Side | Approx. Upgrade Price |
|---|---|

| Fresh Steamed Asparagus | $2.99 |
| Strawberry Salad | $2.99 |
Premium side prices can vary.

For example, Steakhouse Mac & Cheese creates a richer and heavier steak dinner, while Fresh Steamed Asparagus may appeal more to diners looking for a lighter meal.

Typical soup upgrades can include:
| Soup | Approx. Upgrade Price |
|---|---|
| Bowl Loaded Potato Soup | $2.99 |

Best Sides for Flo’s Filet
The best side depends on what kind of meal you want.
Best Classic Steakhouse Combination
Choose:
Flo’s Filet + Loaded Baked Potato + Salad
This creates a traditional steakhouse-style dinner with steak, potato, and greens.
Best Lighter Combination
Choose:
6 oz Flo’s Filet + Broccoli + Mixed Green Salad
This combination keeps the focus on the steak and may result in fewer calories than combinations built around fries or mac and cheese.
Best Rich Combination
Choose:
9 oz Flo’s Filet + Steakhouse Mac & Cheese + Caesar Salad
This is a larger, richer meal for diners prioritizing flavor and satisfaction rather than calorie reduction.
Best Vegetable-Focused Combination
Choose:
Flo’s Filet + Fresh Steamed Asparagus + Mixed Green Salad
This combination offers steak with two vegetable-focused sides.
LongHorn Flo’s Filet Steak Temperature Options
When ordering Flo’s Filet, customers can select their desired level of doneness.
Common choices include:
| Temperature | Typical Appearance |
|---|---|
| Rare | Cool-to-warm red center |
| Medium Rare | Warm red center |
| Medium | Warm pink center |
| Medium Well | Slight pink center |
| Well Done | Fully cooked center |
Many steak lovers prefer filet cooked medium rare or medium because these temperatures can help maintain tenderness and moisture.
However, steak temperature is ultimately a personal preference.
LongHorn also provides the standard food safety warning that consuming raw or undercooked meat may increase the risk of foodborne illness.
Why Is Flo’s Filet So Tender?
The main reason is the cut of beef.
Filet comes from the tenderloin, a muscle that performs relatively little physical work.
Muscles that perform less work usually contain less tough connective tissue.
That gives tenderloin its famously soft texture.
Unlike ribeye, filet generally does not rely on heavy marbling for flavor.
Instead, its primary strengths are:
- Tender texture
- Mild beef flavor
- Premium presentation
- Relatively lean profile
- Smaller portion options
LongHorn enhances the steak with its signature Grill Seasoning and cooking process.
Flo’s Filet vs LongHorn Ribeye
Many customers compare Flo’s Filet vs Ribeye before ordering.
These two steaks offer very different experiences.
| Feature | Flo’s Filet | Ribeye |
|---|---|---|
| Main Strength | Tenderness | Rich flavor |
| Marbling | Lower | Higher |
| Texture | Soft and tender | Juicy and richly marbled |
| Typical Calories | Lower | Higher |
| Best For | Tender steak lovers | Rich steak lovers |
Choose Flo’s Filet if you want tenderness and a relatively lean steak.
Choose Ribeye if you prefer more marbling and a richer beef flavor.
Neither cut is universally better.
The right choice depends on whether tenderness or marbling matters more to you.
6 oz vs 9 oz Flo’s Filet: Which Should You Order?
The 6 oz Flo’s Filet is better for someone who:
- Wants a smaller portion
- Is watching calories
- Plans to order additional sides
- Wants room for dessert
- Has a moderate appetite
The 9 oz Flo’s Filet may be better for someone who:
- Has a larger appetite
- Wants more protein
- Wants more steak for the additional price
- Does not plan to eat many appetizers
- Prefers steak to be the main focus of the meal
From a portion perspective, upgrading from 6 oz to 9 oz gives you about 50% more steak.
The difference in calories is about 120 calories.
The protein increases from approximately 37 grams to 56 grams.
Is Flo’s Filet Good for a High-Protein Meal?
Yes, Flo’s Filet can be a strong choice for customers seeking a protein-rich steak entrée.
The 6 oz portion contains approximately 37 grams of protein, and the larger 9 oz portion contains approximately 56 grams.
The steak itself also contains very few carbohydrates.
That combination explains why searches such as LongHorn high protein menu, Flo’s Filet protein, and LongHorn low carb steak are common among nutrition-conscious diners.
However, the overall healthfulness of the meal also depends on your sides, sauces, salad dressing, drinks, appetizers, and desserts.
How to Build a Lower-Calorie Flo’s Filet Meal
Ordering steak at a restaurant does not automatically mean you need an extremely high-calorie dinner.
The most important decisions often involve the extras.
Start with the 6 oz Flo’s Filet, which contains around 330 calories.
Then consider choosing a vegetable-focused side such as broccoli.
A simple salad can also work, but dressings, cheese, croutons, and toppings may increase the total calories.
Additional strategies include:
- Choose the 6 oz steak
- Select vegetables instead of fries
- Limit calorie-dense dressings
- Skip unnecessary toppings
- Watch portions of bread
- Choose water or an unsweetened drink
- Avoid ordering several appetizers before the steak
You do not need to remove every indulgent item.
Simply understanding where the extra calories come from can help you customize the meal according to your goals.
Is Flo’s Filet Keto-Friendly?
The steak itself is naturally extremely low in carbohydrates.
The 6 oz steak contains approximately 2 grams of carbs, while the 9 oz portion contains around 3 grams.
That means Flo’s Filet may work well with many low-carb eating patterns.
However, the entire meal may not be low-carb if you choose:
- French fries
- Loaded baked potatoes
- Sweet potatoes
- Rice
- Mac and cheese
- Bread
- Sweet sauces
For a lower-carb combination, steak with broccoli, asparagus, or an appropriately customized salad may be a better option.
Is Flo’s Filet Worth the Price?
Flo’s Filet is positioned as a premium steak.
At approximately $26.99 for 6 oz and $32.49 for 9 oz, it costs more per ounce than some larger steak cuts.
That is typical for filet because beef tenderloin is a premium cut.
People who prioritize the largest possible steak for their money may prefer another option.
However, Flo’s Filet may be worth the price for diners who value:
- Exceptional tenderness
- Center-cut filet
- LongHorn signature seasoning
- Smaller premium portions
- High protein
- Lower carbs
- Classic steakhouse presentation
The filet has also remained associated with LongHorn’s menu for decades, giving it strong recognition among regular customers.
