For Arby’s keto ordering, choose Steak Nuggets with Ranch or Buffalo dip, if they’re available. Two five-piece portions make a lower-carb meal; bunless roast beef is another request to consider. Skip fries, breaded sides and shakes; the meat logo doesn’t extend to everything in the bag.
All figures below come from the Arby’s Nutrition & Allergen Information PDF, retrieved October 24, 2026. The document says its information is effective as of September 2026. Values are as published by the chain, per listed serving unless an order explicitly combines servings.
Start with food you can actually count
| Item and serving | Calories | Total carbs | Fiber | Protein |
|---|---|---|---|---|
| Steak Nuggets, 5 pieces | 140 | 2g | 1g | 20g |
The nuggets appear in the guide’s limited-time section. Check availability before planning lunch around them.
I prefer two of the listed five-piece nugget portions with a counted dip. It’s a straightforward order with a clear serving size. The smaller serving is a light meal or snack, so don’t mistake it for a large sandwich replacement.
For two five-piece portions, calculated net carbs are 4g minus 2g fiber, or 2g. Use that portion when following the orders below.
What about bunless roast beef?
Ask for a Classic Roast Beef without its bun, with sauce on the side. Arby’s nutrition guide lists a separate sesame bun but doesn’t identify which sandwich builds use that exact portion, so the sandwich counts below stay as served.
Keep the order simple rather than adding fries to make it a combo. Choose a dip from the table and count the portion you use.
Count sauces by their own servings
| Item and serving | Calories | Total carbs | Fiber | Protein |
|---|---|---|---|---|
| Ranch Dipping Sauce, 28g | 100 | 1g | 0g | 1g |
| Buffalo Dipping Sauce, 28g | 10 | 2g | 0g | 0g |
| Horsey Sauce, 14g | 60 | 3g | 0g | 0g |
| Arby’s Sauce, 14g | 15 | 3g | 0g | 0g |
| Cheddar Cheese Sauce, 43g | 50 | 4g | 0g | 1g |
Horsey Sauce and Horsey Ranch are different names in the guide. The table uses Horsey Sauce, not the limited-time Horsey Ranch entry. Mixing them up makes an apparently tidy food log rather less tidy.
Ranch is a lower-carb dipping choice here, but the whole portion still adds calories. Cheddar Cheese Sauce also has its own carbs; cheese sauce isn’t a free topping just because cheese is in the name. Use one listed portion rather than treating unlimited dipping as part of the meat.
Foods to leave out of the keto order
| Item and serving | Calories | Total carbs | Fiber | Protein |
|---|---|---|---|---|
| Classic Roast Beef, with bun | 360 | 37g | 2g | 23g |
| Classic Beef ‘n Cheddar, with bun | 450 | 45g | 2g | 23g |
| Classic French Dip & Swiss/Au Jus, as served | 530 | 50g | 2g | 34g |
| Curly Fries, medium | 410 | 49g | 5g | 5g |
| Mozzarella Sticks, 4 pieces | 440 | 37g | 2g | 19g |
| Chicken Tenders, 3 pieces | 370 | 28g | 2g | 23g |
| Vanilla Shake, small | 480 | 70g | 0g | 12g |
The French Dip row includes its au jus, and the sandwich rows include bread.
Mozzarella Sticks and Chicken Tenders belong here because of their listed carb counts. Removing a sandwich bun doesn’t remove breading from a different item. The small Vanilla Shake is also a sweet drink, not a clever breakfast substitute.
There’s no reason to add a side just because the ordering screen offers one. A meat order with a dip can be the whole food order. Fries don’t become a required nutrient when they’re sold as a combo.
Complete orders, counted
| Order | Calories | Total carbs | Net carbs | Protein |
|---|---|---|---|---|
| 2 orders of 5 Steak Nuggets, no dip | 280 | 4g | 2g | 40g |
| 2 orders of 5 Steak Nuggets + ranch | 380 | 5g | 3g | 41g |
| 2 orders of 5 Steak Nuggets + Buffalo dip | 290 | 6g | 4g | 40g |
| 5 Steak Nuggets + ranch (small meal) | 240 | 3g | 2g | 21g |
| Comparison: Classic Roast Beef + medium Curly Fries | 770 | 86g | 79g | 28g |
| Comparison: 3 Chicken Tenders + ranch | 470 | 29g | 27g | 24g |
The first four rows are lower-carb choices using the exact nugget and sauce servings. The last two show why the sandwich-and-fries default and breaded chicken aren’t equivalent swaps. No drink, extra sauce or unlisted topping is included in these totals.
How to order
- Check for Steak Nuggets and choose the listed piece count.
- Ask for the nuggets on their own, rather than a bowl with a starchy base.
- Pick a single counted dip, such as Ranch or Buffalo.
- Leave fries, Mozzarella Sticks and shakes out of the order.
- For roast beef, ask for no bun and sauce on the side.
Steak Nuggets and a dip keep the order simple. If you’d rather have roast beef, make the bread-free request clearly and check the container before leaving.
