Dunkin' Nutrition Calculator: The Short Answer
The Sourdough Breakfast Sandwich has 31g of protein — the most of any item at Dunkin' — for 630 calories, with 57g of carbs and 31g of fat. For most adults that is roughly a third to a half of a day's protein in one menu item.
Total grams are only half the story, though. Measured as protein per 100 calories — the number that matters when protein has to fit inside a calorie target — the menu's winner is the Latte, Whole Milk (Medium) at 5.9g per 100 calories (10g protein for 170 calories). The ranking below shows both measures side by side.
The Highest-Protein Dunkin' Items, Ranked
Every figure is taken from the Dunkin' calculator. Read the protein-per-100-calories column if you are fitting protein into a deficit; read total protein if you simply need the biggest single hit.
| Item | Calories | Protein | Protein / 100 cal | Fat | Sodium |
|---|---|---|---|---|---|
| Sourdough Breakfast Sandwich | 630 | 31g | 4.9g | 31g | 1300mg |
| Sausage, Egg & Cheese Croissant | 710 | 25g | 3.5g | 50g | 1310mg |
| Turkey Sausage, Egg & Cheese Muffin | 470 | 23g | 4.9g | 25g | 1040mg |
| Bacon, Egg & Cheese Croissant | 510 | 19g | 3.7g | 34g | 870mg |
| Egg & Cheese Sandwich | 340 | 13g | 3.8g | 16g | 660mg |
| Caramel Swirl Hot Latte (Medium) | 340 | 11g | 3.2g | 9g | 170mg |
| Plain Bagel | 300 | 11g | 3.7g | 2g | 620mg |
| Latte, Whole Milk (Medium) | 170 | 10g | 5.9g | 9g | 140mg |
The Trade-Off Nobody Mentions: Sodium
High-protein fast food usually bills you in sodium rather than calories. The saltiest item here, the Sausage, Egg & Cheese Croissant, carries 1310mg, and several top-protein items sit above 1,000mg. That does not disqualify them — it means the rest of the day should run lighter on salt, and water should be the default drink beside them.
If you are combining two high-protein items to build a 60g-plus meal, run the pair through the calculator first: protein adds up exactly as you hope, but so does sodium, and the total is the number worth knowing before you order.
- Most protein: Sourdough Breakfast Sandwich — 31g (630 cal)
- Most efficient: Latte, Whole Milk (Medium) — 5.9g protein per 100 cal
- Highest fibre among protein picks: Frozen Chocolate (Medium) — 3g fibre
What One Sourdough Breakfast Sandwich Does to Your Day
Set against the standard 2,000-calorie reference day, one Sourdough Breakfast Sandwich uses 32% of the day's calories, 62% of the protein target, 21% of the carb allowance and 40% of the fat budget. Its 1300mg of sodium is 57% of the 2,300mg daily guideline — the figure that most often surprises people, because sodium concentrates in restaurant food far faster than calories do.
None of those percentages is a verdict on its own. A Sourdough Breakfast Sandwich at 32% of the day's calories can be a sensible meal anchor; the same item plus a large side and a sweetened drink can quietly pass 60% of the day before dinner. The calculator's daily-value bars exist for exactly this check: build the whole order, not just the headline item, and read the day you are actually committing to.
- Sourdough Breakfast Sandwich: 630 cal · 31g protein · 57g carbs · 31g fat
- Sodium: 1300mg (57% of the daily guideline)
- Sugar: 2g of the 50g daily value · Fibre: 3g of 28g
Check It Yourself in the Dunkin' Calculator
Every figure in this article comes from the Dunkin' calculator on this site, and you can reproduce the answer in under a minute: open the calculator, add your two highest-protein picks together exactly as you order it — size, side, drink and sauce included — and read the live totals. Published menu numbers describe the standard build; your build is the one you actually eat, and the two diverge most often on drinks, sauces and portion upgrades.
If your total differs from the headline figure here, the difference is information, not error: it tells you which of your regular additions carries the calories. Change one component at a time and watch which single swap moves the total most — that swap, repeated, is worth more than any one-off light order.
The Full Nutrition Profile of the Sourdough Breakfast Sandwich
Here is the complete panel for the Sourdough Breakfast Sandwich, exactly as the Dunkin' calculator carries it, with each nutrient also expressed as a percentage of its daily value on a 2,000-calorie reference diet. Read down the percentage column rather than the grams: it is the fastest way to see which nutrient this item is really about. For the Sourdough Breakfast Sandwich, the standout is protein, at 62% of a full day in a single item.
Two cautions belong with any single-item panel. First, published values describe the standard build — your portion, your sauce quantity and your size can move every line. Second, percentages are shares of a whole day, not grades: an item at 45% of the day's sodium is a problem only in the context of what else the day holds, which is why the calculator totals the full order rather than judging items one at a time.
| Nutrient | Amount | % Daily Value |
|---|---|---|
| Calories | 630 | 32% |
| Protein | 31g | 62% |
| Carbohydrates | 57g | 21% |
| Total Fat | 31g | 40% |
| Dietary Fibre | 3g | 11% |
| Sugars | 2g | 4% |
| Sodium | 1300mg | 57% |
Where This Answer Sits on the Whole Dunkin' Menu
Zoom out and the Dunkin' menu tracked here spans 34 items across 6 categories, from the Bottled Water at 0 calories to the Sausage, Egg & Cheese Croissant at 710 — a 710-fold spread inside one restaurant. The average item is about 306 calories, 1 items pass 700 calories, and 27 of 34 sit under 500. Any single number quoted from this menu means little until it is placed inside that spread.
That spread is also the opportunity. A menu this wide almost always contains a build for the goal you actually have — the protein target, the sodium ceiling, the 500-calorie lunch — provided the order is assembled deliberately rather than inherited from habit. The rankings in this article are the map; the calculator is where you test the route before you travel it.
- Menu range: 0 cal (Bottled Water) to 710 cal (Sausage, Egg & Cheese Croissant)
- 18 items under 300 calories · 27 under 500 · average 306
- Most protein-dense: Latte, Whole Milk (Medium) at 5.9g protein per 100 cal
The One Swap That Changes the Answer
If the Sourdough Breakfast Sandwich is your usual order and the numbers above are more than you wanted, the highest-value single change on this menu is the Latte, Whole Milk (Medium): 170 calories against 630 (460 fewer), 10g of protein against 31g, and 140mg of sodium against 1300mg (1160mg less salt). One swap, repeated weekly, is worth more than a month of good intentions.
Not every swap has to be a downgrade in enjoyment: the pattern that works at Dunkin' is swapping the component, not the meal — the same style of order rebuilt around a lighter anchor, with the sauce, cheese or side demoted from default to deliberate. Price both versions in the calculator once and the better default usually picks itself.
