Keto at Long John Silver’s works best with grilled salmon or grilled shrimp ordered as separate pieces, plus Green Beans. Skip battered fish, chicken strips, rice bowls and the automatic hushpuppies. The useful distinction is how the seafood is prepared and served, not whether the menu calls it fish.
All figures below come from the Long John Silver’s Allergen & Nutritional Guide, retrieved October 24, 2026. The guide is marked Updated 2026. Values are as published by the chain; net carbs subtract published fiber from total carbs.
Grilled pieces are different from grilled bowls
| Item and serving | Calories | Total carbs | Fiber | Net carbs | Protein |
|---|---|---|---|---|---|
| Grilled Salmon, 1 piece | 92 | 0g | 0g | 0g | 20g |
| Grilled Shrimp, 3 pieces | 28 | 0g | 0g | 0g | 5g |
| Battered Alaskan Pollock, 1 piece | 246 | 15g | 1g | 14g | 11g |
| Battered Alaskan Cod, 1 piece | 212 | 13g | 1g | 12g | 11g |
| Chicken Breast Strip, 1 piece | 145 | 7g | 1g | 6g | 10g |
| Breaded Clam Strips, 1 portion | 343 | 24g | 2g | 22g | 18g |
| Grilled Salmon Rice Bowl, 1 bowl | 390 | 59g | 5g | 54g | 26g |
The separate Grilled Salmon piece lists 0g carbs and 20g protein. The Grilled Salmon Rice Bowl lists 59g carbs. Same fish, very different container of dinner. I would order the pieces and choose the side myself.
Grilled Shrimp is listed per three pieces. That small portion has 5g protein, so think about the amount of food before ordering it as your entire meal. The counted examples below use multiple portions rather than pretending a tiny add-on is a substantial dinner.
Battered Alaskan Pollock, Battered Alaskan Cod and Chicken Breast Strips all bring carbs from their coating. Choose the grilled seafood for the lowest-carb meal.
Scraping off batter doesn’t turn fried fish into the separately listed grilled portion. Long John Silver’s guide doesn’t give a count for fish with the coating removed.
The side and sauce can change the answer
| Item and serving | Calories | Total carbs | Fiber | Net carbs | Protein |
|---|---|---|---|---|---|
| Green Beans, individual | 25 | 4g | 1g | 3g | 1g |
| Creamy Ranch, 1 packet | 50 | 1g | 0g | 1g | 0g |
| Creamy Garlic Butter Sauce, 1 oz | 101 | 1g | 0g | 1g | 0g |
| Tartar Sauce, 1 packet | 40 | 3g | 0g | 3g | 0g |
| Cocktail Sauce, 1 dipping cup | 20 | 4g | 0g | 4g | 1g |
| Malt Vinegar, 0.5 oz | 0 | 0g | 0g | 0g | 0g |
| Louisiana Hot Sauce, 1 teaspoon | 0 | 0g | 0g | 0g | 0g |
| Coleslaw, individual | 170 | 18g | 2g | 16g | 1g |
| Waffle Fries, individual | 309 | 33g | 4g | 29g | 4g |
| Hushpuppies, 2 pups | 186 | 17g | 1g | 16g | 2g |
| Crumbles, 1 oz | 176 | 9g | 0g | 9g | 2g |
Green Beans are the straightforward side here: an individual portion lists 4g total carbs and 1g fiber, giving 3g net carbs. Coleslaw lists 18g total and 2g fiber. Both are vegetables, but the finished dishes aren’t nutritional twins.
Creamy Ranch adds 1g carbs per packet. Tartar Sauce adds 3g per packet, while Cocktail Sauce adds 4g per dipping cup. Tartar isn’t automatically forbidden, and cocktail isn’t automatically the lower-carb choice. Read the serving as well as the sauce name.
Malt Vinegar and the listed teaspoon of Louisiana Hot Sauce each publish 0g carbs. Creamy Garlic Butter Sauce adds 1g per ounce, along with 101 calories. It’s optional flavor, not an ingredient you need to make fish qualify for keto.
Hushpuppies and Crumbles aren’t decorative exceptions. The listed two Hushpuppies add 17g carbs. An ounce of Crumbles adds 9g. If they arrive in the box, decide whether you’re eating them before applying a grilled-only total.
Complete orders, counted
The first four orders include only the named grilled pieces, individual side and measured condiment. They exclude rice, hushpuppies, Crumbles and any other sauce. The final two rows are high-carb comparisons to skip for a low-carb meal.
| Order | Calories | Total carbs | Net carbs | Protein |
|---|---|---|---|---|
| 2 Grilled Salmon pieces + individual Green Beans + Malt Vinegar | 209 | 4g | 3g | 41g |
| 2 Grilled Salmon pieces + individual Green Beans + Creamy Ranch | 259 | 5g | 4g | 41g |
| 1 Grilled Salmon + 9 Grilled Shrimp + individual Green Beans + garlic butter | 302 | 5g | 4g | 36g |
| 12 Grilled Shrimp + individual Green Beans + Tartar Sauce | 177 | 7g | 6g | 21g |
| Comparison: 2 Battered Pollock + individual Waffle Fries + 2 Hushpuppies | 987 | 80g | 73g | 28g |
| Comparison: Grilled Salmon Rice Bowl + Tartar Sauce | 430 | 62g | 57g | 26g |
The shrimp-heavy rows are still fairly light meals. Choose a portion that fits your appetite rather than treating low calories as the goal of keto. Adding more plain grilled pieces changes the protein and calories; adding rice changes the carb picture too.
Ask whether your restaurant can serve the grilled pieces and sides separately before ordering.
How to order
- Ask for Grilled Salmon or Grilled Shrimp as separate pieces. State the number of pieces.
- Choose an individual Green Beans side, not a standard rice bowl.
- Request no Hushpuppies or Crumbles with the order.
- Pick a measured sauce serving or the listed Malt Vinegar portion.
- Choose the listed unsweetened brewed tea if you want a drink. A small serving lists 0 calories and 0g carbs.
- Check for extra sides and sauce before using a counted total.
Keep the order simple
The right order is fairly plain. That’s fine. Dinner doesn’t need a costume, and a grilled label doesn’t excuse a rice base.
