LongHorn Steakhouse Keto Guide

The complete low-carb dining strategy for steak lovers. Learn what to order, what to customize, and hidden sugars to avoid.

Navigating the Menu on a Low-Carb Diet

Casual dining restaurants can be minefields of hidden carbohydrates. Fortunately, as a steakhouse, LongHorn is naturally one of the absolute best places to dine if you follow a ketogenic or low-carb lifestyle. Steak is a perfect zero-carb source of protein and fat. However, marinades, sauces, breadings, dressings, and side dishes can quickly kick you out of ketosis if you aren't careful.

In this guide, we break down the carbohydrate counts of popular menu items and offer ordering strategies to help you maintain a keto lifestyle while enjoying a premium steakhouse dinner.

Keto-Friendly Main Course Recommendations

Naturally, steaks are the star of the show. Almost all cuts of steak at LongHorn contain **0g of net carbohydrates** in their natural form. Seasoning blends like Prairie Dust contain salt, pepper, garlic, onion, and spices, which add negligible carbs (under 1g per steak).

Steak Cut Serving Size Calories Net Carbs Fat Protein
Flo's Filet® 6 oz 330 0g 16g 45g
Outlaw Ribeye® 20 oz 1280 0g 80g 90g
Renegade Sirloin 8 oz 390 0g 18g 58g
New York Strip 12 oz 630 0g 38g 70g

Other Low-Carb Entrees:

  • Lemon Garlic Chicken: 4g net carbs. A delicious herby choice served skin-on.
  • LongHorn Salmon: 2g net carbs. Premium grilled salmon glazed with a light, non-sweet herb marinade.
  • Redrock Grilled Shrimp: 2g net carbs. Grilled on skewers and brushed with garlic butter. (Avoid rice pilaf; request double broccoli).

Low-Carb Side Dishes

Standard steak sides like French fries, loaded baked potatoes, and seasoned rice are high in carbohydrates and must be avoided. Instead, substitute them with these low-carb vegetable options:

  • Steamed Broccoli: 2g net carbs (90 cal). Request butter on top for extra healthy fats.
  • Fresh Grilled Asparagus: 3g net carbs (90 cal). Tossed in oil and fire-grilled.
  • Mixed Greens Side Salad: 2g net carbs. Swap the default dressing for oil and vinegar or creamy Caesar, and request **no croutons**.

Hidden Carbs & Items to Avoid

⚠️ Watch Out for Added Sugars: BBQ sauces, honey mustards, sweet glazes, and sweet marinades are loaded with sugar. Avoid the Baby Back Ribs unless you request them dry (no sauce). The Parmesan Crusted Chicken contains about 12g of carbs per serving due to the breadcrumb topping binder; while relatively low, it might be too high for strict keto. Request it without the breadcrumbs.

Strictly Avoid:

  • Complimentary fresh-baked bread (each slice is ~20g of carbs).
  • Appetizers like the Texas Tonion, Wild West Shrimp, and Firecracker Chicken Wraps (all are heavily breaded or wrapped).
  • All soups (standard starchy thickeners are used in the potato and onion broths).

Keto Drinks & Alcohol

Stick to unsweetened iced tea, black coffee, diet sodas, or water. If you want an alcoholic beverage, choose light beers, dry wines, or hard spirits mixed with club soda or diet sodas. Avoid margaritas and specialty cocktails, which are mixed with sugary syrups.

Frequently Asked Questions

Yes, standard LongHorn grill seasonings contain zero to negligible carbohydrates. The Prairie Dust and Grill Seasoning blends rely on salt, black pepper, garlic, onion, and spices. Avoid sweet sauces like BBQ or glaze, which contain added sugars.
Fresh Steamed Broccoli and Fresh Grilled Asparagus are the best keto sides, containing 2g-3g net carbs per serving. Be sure to request no flour-based thickeners, and feel free to add butter or sour cream for extra fat.
Most soups at LongHorn, including the potato and onion soups, contain flour as a thickener and are not keto-friendly. We recommend sticking to salads with oil and vinegar, or low-carb vegetable sides.
