Sauce is the single most consequential free decision at the Subway counter. Vegetables add almost nothing to a sandwich's calorie count; sauce can add three hundred calories to a Footlong without changing how full you feel. It is also the difference between a memorable sub and a dry one, so the goal is not avoiding it — it is spending it deliberately.
The full sauce list
Availability varies: every store carries the core set, and a handful of the others are regional or rotate with limited-time promotions.
| Sauce | Approx. calories | Vegan? | Pairs well with |
|---|---|---|---|
| Mayonnaise | ~110 cal / 6-inch serving | No (egg) | Tuna, ham, club subs — but you rarely need it |
| Light mayonnaise | ~50 cal | No (egg) | Same jobs, half the cost |
| Yellow mustard | ~5 cal | Yes | Turkey, ham, roast beef — the best value on the counter |
| Deli brown mustard | ~5 cal | Yes | Pastrami-style and roast beef builds |
| Honey mustard | ~30 cal | Usually not (honey) | Chicken, turkey, kids' subs |
| Sweet onion | ~40 cal | Yes | Teriyaki chicken, veggie subs |
| Chipotle southwest | ~90 cal | No (egg) | Steak, MexiCali, meatball |
| Ranch / Peppercorn ranch | ~110 cal | No (egg, dairy) | Chicken bacon ranch, cold veg subs |
| Baja chipotle | ~80 cal | No (egg) | Steak and chicken with jalapeño |
| Buffalo sauce | ~50 cal | Often yes | Chicken, with blue-cheese-style ranch |
| BBQ sauce | ~35 cal | Yes | The Outlaw, crispy onion builds |
| Oil (blended) | ~45 cal | Yes | Italian builds, with vinegar |
| Red wine vinegar | ~0 cal | Yes | Everything cold — the most underused option |
| Sriracha (where stocked) | ~15 cal | Yes | Chicken, steak, egg breakfast subs |
| Garlic aioli | ~100 cal | No (egg) | The Great Garlic, mozzarella builds |
| Roasted garlic / Parmesan vinaigrette | ~35–70 cal | Varies | Bella Mozza, veggie subs |
Calories are per standard 6-inch serving and roughly double on a Footlong. Servings are poured by hand, so a heavy pass of ranch can be closer to 150 calories than 110. Vegan status is based on published US ingredient statements and can change — always check current information if it matters to you, and read our vegetarian and vegan guide.
The four sauces that do the most work
- Red wine vinegar. Zero calories, and it makes cold subs taste seasoned rather than plain. If you only change one thing about how you order, change this.
- Yellow mustard. Five calories, sharp, and it stops turkey and ham from tasting like nothing.
- Chipotle southwest. The best flavour-per-calorie creamy sauce. Use it instead of ranch and mayonnaise, not alongside them.
- Sweet onion. The only sweet sauce worth the sugar, and only on chicken or veg.
Combinations that actually work
- Mustard + red wine vinegar + black pepper + oregano — the classic deli finish.
- Chipotle southwest + jalapeño + extra onion — steak, MexiCali, egg breakfast subs.
- Buffalo + light ranch — chicken; use light ranch or it becomes a dip.
- Oil + vinegar + oregano — B.M.T., Spicy Italian, Supreme Meats.
- Honey mustard + light mayo — clubs and turkey, especially for children.
Combinations to avoid
Two creamy sauces on the same sub (ranch and mayonnaise, garlic aioli and chipotle) is the most common mistake — you cannot taste either one and you have added 200 calories. Sweet plus smoky (sweet onion and BBQ) fights itself. And sauce plus a wet toasted filling like marinara mostly produces a soggy sandwich; see our meatball guide.
Sauce on the side
Any sauce can be requested in a cup, and it is the best trick on the menu for two situations: delivery orders where a sauced sub steams in the bag, and calorie control, because you will use less than the counter pours. Ask when you order rather than after it is wrapped.
