An Arby’s Roast Beef Slider delivers 10 grams of protein, based on the chain’s published nutrition data.
Arby’s Roast Beef Slider Protein — What You Get
The small roast beef slider at Arby’s clocks in at 10 grams of protein per sandwich. That figure comes from the chain’s current nutrition sheet. The slider weighs 71 grams and lists 170 calories with 7 grams of fat and 16 grams of carbs, so protein accounts for 40 calories. In plain terms, you get a compact bite with a quarter of its calories from protein.
That ratio matters when you want quick protein without a full-size sandwich. The slider uses thinly sliced beef and a small bun with a slice of processed Swiss. The meat delivers most of the protein, while the bun and cheese add a small lift. If you want more protein from the same footprint, the next sections show fast tweaks that raise the count without blowing up calories or sodium.
| Metric | Per Slider | Per 100 g |
|---|---|---|
| Serving Weight | 71 g | — |
| Calories | 170 kcal | 240 kcal |
| Protein | 10 g | 14 g |
| Carbohydrates | 16 g | 23 g |
| Fat | 7 g | 10 g |
| Sodium | 490 mg | — |
If you like to sanity-check numbers against a general benchmark, a plain roast beef sandwich in nutrient databases lands near 15 grams of protein per 100 grams. That lines up with the slider’s rate, which sits near 14 grams per 100 grams once you scale the serving. You can cross-reference that baseline on a database page that compiles roast beef sandwich data from USDA sources: Roast Beef Sandwich nutrition.
Portion Size Reality At The Counter
Menu photos can make any slider look bigger than it feels in hand. The published serving weight helps set real expectations. At 71 grams, this sandwich sits in snack territory for most adults. If you aim for 25 to 35 grams of protein in a single sitting, one slider won’t hit that. That’s not a flaw; it just means you’ll likely treat it as part of a meal, not the whole plate.
Since the beef is shaved thin, texture stays tender and easy to eat. That texture also means quick bites. To slow things down, add a side that needs extra chewing, like nuggets. Chewing more can help you feel done with fewer calories than piling on heavy sauces.
How Serving Size And Build Change Protein
Protein numbers shift with small changes to the build. The default slider includes roast beef, Swiss, and a slider bun. Add cheese or bacon and your protein moves up, while sauces barely change the count. The lines below list common add-ons from Arby’s own toppings chart along with the protein they add per serving.
Cheese Choices That Move The Needle
Processed Swiss adds 3 grams of protein per slice. A mild cheddar slice adds 5 grams. If you like a fuller melt, swapping to cheddar gives a clear bump without a large calorie jump. Cheese sauce doesn’t move protein in a meaningful way, so it’s more about flavor and texture.
Bacon, Onions, And Sauces
Three half strips of bacon add 5 grams of protein and a salty crunch. Crispy onions add just 1 gram. Sauces show near zero protein. If your goal is more protein with minimal volume, bacon or an extra cheese slice are the best levers among standard toppings.
Salt can rise quickly. The base slider already lists 490 milligrams of sodium. Bacon and cheese both add more. If you’re watching sodium, consider a lighter hand with sauces and pick a water or unsweet tea alongside.
Ingredient Notes That Affect Macros
The small bun brings a bit of protein on its own. The toppings sheet lists a 4-inch sesame seed bun at 7 grams of protein per roll, which helps explain why the slider’s protein-per-100-gram number stays close to a plain roast beef sandwich benchmark. That bun also adds a chunk of the carbs, so swapping sauces does less to the macro split than changing cheese or adding bacon.
If you like extra heat, jalapeños add crunch and a touch of moisture without changing protein. That makes the Jalapeño roast beef variant a fun swap when you want the same protein with more bite.
How It Stacks Up Against Other Sliders
Arby’s runs several small sandwiches in the same price tier. Protein varies by meat and breading. Chicken sliders that use a fried tender land around the same protein as the roast beef option, with a bit more sodium from the breading. The table below compares protein per sandwich across popular choices so you can pick the one that fits your goals.
| Menu Item | Serving Weight | Protein (g) |
|---|---|---|
| Roast Beef Slider | 71 g | 10 |
| Jalapeño Roast Beef Slider | 79 g | 10 |
| Chicken Slider | 79 g | 11 |
| Buffalo Chicken Slider | 92 g | 13 |
The roast beef option sits in the middle of the pack on protein while staying lighter on calories than the larger chicken builds. If you want extra protein without jumping to a full sandwich, the Buffalo chicken slider gives a small bump. If you want the same flavor profile as the standard roast beef version, order two of the original size and skip heavy sauces to keep calories predictable.
Smart Pairings If You Want More Protein
One slider works as a snack; two sliders or a slider plus a side can turn into a balanced meal. These pairings land more protein within a modest calorie budget.
Pair With Nuggets
Four Premium Nuggets add 17 grams of protein. Six pieces add 25 grams. That moves your meal into lunch-worthy range without pushing the total portion too high. The texture contrast also slows eating, which can help you feel done with fewer add-ons.
Lean Toward Simple Sides
Curly Fries bring crunch but little protein. If the goal is protein, go with nuggets, a second slider, or milk. A low-fat chocolate milk in the kids set lists 7 grams of protein for the small carton.
Swap Sauce Strategy
High-sugar dips add flavor but don’t help your protein target. Ranch adds minimal protein; Buffalo dip adds none. When you want more protein, make toppings do the work and let the sauce stay light.
Calories, Macros, And Goals
Ten grams of protein equals 40 calories. With a 170-calorie slider, that’s 24 percent of calories from protein, 37 percent from fat, and 39 percent from carbs. That split matches a small snack that leans balanced rather than high protein. For a higher share from protein, add cheddar or bacon as above, or pair with nuggets.
For weight-focused plans, volume and satiety often matter more than a single macro. Two sliders give 20 grams of protein and about 340 calories. A slider plus a 4-piece nuggets set lands near 27 grams of protein for a similar calorie range, with more chew per bite due to breading. Pick the texture and flavor that keeps you satisfied longer; that’s how you avoid second trips.
On training days, a quick protein target at 25 to 35 grams works for many people. One slider won’t reach that mark alone. Use the pairing ideas above, or eat the slider as a pre-meal snack to bridge a longer gap.
Ordering Tips To Nudge Protein Higher
Ask For Extra Cheese
Add a second cheese slice for a quick 3 to 5 gram lift. Cheddar gives the larger bump. You’ll add sodium and fat along with protein, so balance the rest of your meal.
Add Bacon When You Want It
Bacon brings 5 grams of protein in a tiny package. If you choose bacon, skip heavy sauces to keep calories in check.
Go With Two Small Sandwiches
Two small roast beef sliders beat one full-size sandwich on flexibility. You can eat one now and one later, or split with a friend. Double order means 20 grams of protein with predictable calories.
Method: Where These Numbers Come From
Protein, calories, and topping counts come from Arby’s nutrition sheet. You can read the current PDF here: Arby’s Nutrition & Allergen Information (July 2024). The per-100-gram benchmark for a plain roast beef sandwich comes from a database that compiles USDA-sourced values: Roast Beef Sandwich nutrition. Restaurant builds vary by location, so treat these numbers as a tight range rather than lab values.
If you track macros closely, use the chain’s calculator on the day you order. Menus rotate and recipes can shift. The published sheet lists serving weights, which helps you spot when a sandwich feels light or heavy compared with the standard.
