Arby’s Double Beef ’n Cheddar delivers 39g of protein per sandwich, per the chain’s October 2025 nutrition guide.
If you’re tracking macros and love roast beef, the protein in the Double Beef ’n Cheddar lands in the sweet spot for a single-sandwich meal. Below you’ll find the exact numbers, how they compare across sizes, and simple swaps to tilt your order toward your daily protein target without turning lunch into a project.
Protein In Arby’s Beef ’N Cheddar Double: The Breakdown
Arby’s lists the Double Beef ’n Cheddar at 39g protein and 630 calories with 32g fat and 48g carbs. The Classic size carries 23g protein; the Half Pound hits 49g. Those figures come straight from the brand’s PDF nutrition sheet, which is the source of truth for menu planning across the chain’s U.S. locations.
Quick Compare: Beef ’N Cheddar Sizes
Use this at-a-glance chart to line up protein and calories across the three core sizes.
| Beef ’N Cheddar Size | Calories | Protein (g) |
|---|---|---|
| Classic | 450 | 23 |
| Double | 630 | 39 |
| Half Pound | 740 | 49 |
Why the jump? The Double and Half Pound sandwiches add more thin-sliced roast beef on the same onion roll with cheddar sauce and red ranch. More meat raises protein fast; the bun and sauces stay steady, so calories don’t scale in a straight line with protein. That makes the Double a handy middle ground when you want a near-40g protein hit without crossing 700+ calories.
How The Protein Is Built
Most of the protein comes from the roast beef. Cheddar sauce contributes a little, but the meat carries the load. Standard deli-style roast beef lands around 18–26g protein per 100g depending on cut and moisture. That gives a useful lens on why adding a meat layer moves the needle more than swapping sauces or bread styles.
Who This Sandwich Fits
- Lunch lifters: One Double covers a big chunk of a 120–150g daily protein target.
- Calorie watchers: 630 calories is manageable for a one-item meal if you pair it with water or diet soda.
- Desk-day eaters: No fork needed, macro-dense, and fast.
Macro Details: Carbs, Fat, Sodium, And Fiber
The Double logs 48g carbs and 32g fat. Sodium lands at about 2100mg, which is high for a single item. If you’re sensitive to salt or you’re planning a salty side, pace the rest of the day. Fiber sits low since the bun is the only source. If you want more balance, add a side salad at another meal or split the sandwich and pair half with fruit later on.
Order Tweaks To Nudge Protein Up Or Calories Down
- Skip extra sauce: The red ranch adds sugar and sodium; asking for light sauce trims calories with almost no hit to protein.
- Go Half Pound when you need 50g+: If your plan calls for a big protein anchor, the Half Pound’s 49g gets you there in one shot.
- Pair with a zero-cal drink: Keep the sandwich as the calorie center; save room for a protein-lean dinner.
- Add plain roast beef on the side: A simple roast beef sandwich adds protein cleanly; you can eat half now, half later.
How It Stacks Up Against Other Arby’s Protein Plays
Arby’s menu includes several items that bring solid protein. When you’re deciding between them, look past calories and scan protein per item so you can build your day without guesswork.
Protein Per Item: Smart Picks
These menu numbers come straight from the same brand sheet as the Beef ’n Cheddar. They help you swap without losing your macro plan.
- Classic Roast Beef: 23g protein, 360 calories.
- Double Roast Beef: 38g protein, 510 calories.
- Half Pound Roast Beef: 48g protein, 610 calories.
- Turkey Ranch & Bacon Sandwich: 46g protein, 810 calories.
- Steak Nuggets (5-piece): 17g protein, 340 calories; (9-piece): 30g protein, 600 calories.
- Mozzarella Sticks (6-piece): 29g protein, 650 calories.
If you’re choosing between the Double Beef ’n Cheddar and Double Roast Beef, the difference is sauce and cheese. Protein stays in the same ballpark, calories shift with toppings. When the goal is leaner, the roast-beef-only builds are the tidiest path. When you want comfort, the cheddar version gives you flavor with only a small protein trade-off.
Building A Day Around A 39g Lunch
Here’s a simple template that keeps macros balanced. It starts with the Double at midday and fills in morning and evening without carb overload.
Sample Day (Approx. 2,000 Calories)
- Breakfast: Greek yogurt cup plus berries (20–25g protein).
- Lunch: Double Beef ’n Cheddar (39g protein) with water or diet soda.
- Snack: A small whey shake or a couple of cheese sticks (20–25g protein).
- Dinner: Chicken breast or lean steak with veggies and rice (40–50g protein).
This layout lands near 120–140g protein without juggling specialty foods. If you lift or run, move the higher-carb items closer to training. If you’re cutting, trim sauces and stick to zero-cal beverages.
Ingredient Notes And Allergens
The sandwich uses sliced roast beef, cheddar cheese sauce, the house red ranch, and a toasted onion roll. The menu lists milk, soy, wheat, and sesame among allergens. If you’re managing allergies, verify the current sheet at order time and check whether your location shares fryers or prep space for cross-contact risks.
What The Numbers Don’t Show
Nutrition grids give totals per sandwich; they don’t show weight of each component or batch-to-batch variability. The roast beef’s moisture can swing protein slightly by weight. That’s normal in deli meats and roasts. The posted numbers remain your best guide for planning.

| Menu Item | Protein (g) | Notes |
|---|---|---|
| Double Beef ’n Cheddar | 39 | Flavor pick with cheese and sauce |
| Half Pound Beef ’n Cheddar | 49 | One-item path to ~50g |
| Double Roast Beef | 38 | Leaner profile; no cheese sauce |
| Half Pound Roast Beef | 48 | Near-max protein on the core menu |
| Steak Nuggets (9-piece) | 30 | Pair with a light side for balance |
| Classic Roast Beef | 23 | Lower calorie anchor; add a shake later |
Practical Swaps To Meet Different Goals
Cut Calories, Keep Protein
- Order the Double Roast Beef instead of the cheddar version when you want similar protein with fewer sauce calories.
- Ask for light sauce on the Beef ’n Cheddar to trim sugar and fat without changing protein much.
Push Protein Higher
- Go Half Pound Beef ’n Cheddar for one-item, ~50g protein.
- Add a plain roast beef sandwich and split it across the day to stack an extra 20–25g without blowing up lunch.
Lower Sodium Load
- Skip salty sides and sauces with the Double. Water over soda helps the day’s total land lower.
- Balance the rest of the day with fresh produce and minimally salted meals.
Source Check And How To Verify Numbers
Arby’s publishes a nationwide PDF with calories, macros, and allergens. That sheet is the reference used here, and it’s updated regularly. If you want to double-check a specific location, ask to see the current sheet or open the online guide. For broader context on meat protein, public datasets list roast beef ranges per 100g; that helps explain why adding meat moves protein more than any topping change.
Final Take
The Double Beef ’n Cheddar sits in a handy zone: 39g of protein in a single handheld, with flavor that doesn’t feel like a compromise. When your day calls for a solid protein anchor and quick service, it’s an easy repeat order. Use the charts above, pick the size that fits, and steer sauces and sides to match your plan.
