Keto at Subway: What to Order Low-Carb

The best low-carb order at Subway is a Tuna Protein Bowl with extra cheese and oil-and-vinegar dressing, at about 6 g net carbs and 41 g of protein. Skip the bread and wrap entirely — a Protein Bowl swaps your sandwich fillings into a bowl over greens, cutting the biggest source of carbs at the counter.

Menu data last verified: August 2026, from Subway's official U.S. nutrition information.¹

Subway doesn't run a keto menu, but its build-your-own format makes it one of the easier drive-thru stops to keep low-carb — as long as you order the filling without the bread. This guide ranks every Protein Bowl by net carbs, flags the dressings and sauces that quietly add sugar, and gives you a full sample order under 20 g net carbs.

How do you order keto at Subway?

Ask for any sandwich as a Protein Bowl instead of on bread. Subway keeps the same meat, cheese, and vegetables but serves them over lettuce and spinach with no bun, which removes roughly 40 to 57 g of carbs depending on the bread you'd have chosen.¹ From there, pick a low-carb dressing, add extra fat, and skip anything sweetened.

• Order a Protein Bowl, not a sandwich or wrap. This one swap does most of the work.
• Choose a low-carb dressing — oil and vinegar, mayonnaise, MVP Parmesan Vinaigrette, Peppercorn Ranch, or Roasted Garlic Aioli all run 0 to 1 g net carbs.
• Add cheese, bacon, or sliced avocado for extra keto fat at close to 0 g net carbs.
• Skip Subkrunch topping, croutons, and crispy onions — texture add-ons that carry hidden carbs.
• Ask for double meat or extra cheese if you want more protein without more carbs.
• Check exact totals for your build with the net-carb calculator.

Best low-carb Protein Bowls at Subway, ranked

The lowest-carb Protein Bowls at Subway run 6 to 13 g net carbs, led by Tuna, Oven-Roasted Turkey, and Black Forest Ham. Every bowl below uses the official nutrition figures for a footlong meat portion over lettuce, spinach, tomatoes, onions, green peppers, cucumbers, and olives, before dressing or cheese.¹

Protein Bowl	Net carbs	Protein	Calories
Tuna	6 g	41 g	750
Oven-Roasted Turkey	7 g	38 g	560
Black Forest Ham	7 g	33 g	580
Grilled Chicken	9 g	48 g	620
Chicken & Bacon Ranch	10 g	55 g	760
Cold Cut Combo	10 g	35 g	670
Chipotle Philly	10 g	46 g	600
Steak Philly	11 g	43 g	630
Roast Beef	11 g	35 g	570
B.M.T.	11 g	40 g	820
Spicy Italian	11 g	39 g	960
Big Hot Pastrami	13 g	46 g	740

Tuna Protein Bowl — 6g net carbs

The single lowest-carb bowl on the menu, and the highest fat-to-protein ratio of the group. Order it with oil and vinegar instead of extra mayo if you're also watching calories, since the tuna mix already carries plenty of fat.

Oven-Roasted Turkey Protein Bowl — 7g net carbs

Lean and simple — turkey, cheese, and vegetables with almost no hidden carbs. Add bacon or avocado since this bowl runs lower in fat than the others on the list.

Black Forest Ham Protein Bowl — 7g net carbs

Nearly identical to the turkey bowl in carbs and protein. A safe, boring-in-a-good-way choice if you're ordering somewhere without much time to customize.

Grilled Chicken Protein Bowl — 9g net carbs

The highest protein-to-calorie ratio on the list at 48 g protein for 620 calories. Good pick if you're prioritizing protein over fat for the day.

Chicken & Bacon Ranch Protein Bowl — 10g net carbs

Comes with ranch and bacon built in, which pushes both fat and protein higher — 55 g protein, the most of any bowl. Confirm the ranch used is the standard Peppercorn Ranch, not a sweetened sauce.

Cold Cut Combo Protein Bowl — 10g net carbs

A mix of deli meats with moderate fat. Solid choice, though the sodium runs high (1,930 mg), so pair it with water rather than a salty side.

Chipotle Philly Protein Bowl — 10g net carbs

Steak and cheese with a chipotle kick — 46 g protein and a good fat level for keto satiety. One of the better-tasting picks on this list according to most Subway regulars.

Steak Philly Protein Bowl — 11g net carbs

Straightforward steak and cheese over greens. Reliable across locations since it's a core menu item, not a limited-time offer.

Roast Beef Protein Bowl — 11g net carbs

Lean roast beef keeps the calorie count lower (570) while protein stays solid at 35 g.

B.M.T. Protein Bowl — 11g net carbs

Pepperoni, salami, and ham make this the highest-fat bowl in the ranked set — 68 g of fat. Great if you're running a higher-fat keto day.

Spicy Italian Protein Bowl — 11g net carbs

Similar to the B.M.T. with more heat. Also runs high in fat and calories, so it's a filling, once-a-visit order rather than a daily one.

Big Hot Pastrami Protein Bowl — 13g net carbs

The highest-carb bowl still comfortably under 20 g. Pastrami adds a smokier flavor with 46 g of protein, but sodium runs very high (3,430 mg).

Which dressings and toppings keep it keto?

Oil and vinegar, mayonnaise, and the Parmesan or Peppercorn Ranch dressings all run 0 to 1 g net carbs per serving, making them safe defaults on any bowl or salad. Sauces built around honey, teriyaki, or BBQ are the items most likely to quietly blow your carb budget.

Low-carb (0–1g net carbs): Olive Oil Blend & Vinegar, Mayonnaise, MVP Parmesan Vinaigrette, Peppercorn Ranch, Roasted Garlic Aioli, Baja Chipotle sauce, plain yellow mustard, and any cheese (American, Monterey Cheddar, Pepper Jack, Provolone). Sliced avocado adds 2 g net carbs; smashed avocado adds about 1 g.

Higher-carb, use sparingly or skip: Hot Honey Sauce (8 g net carbs per serving), BBQ Sauce (6 g), Sweet Onion Teriyaki sauce (7 g), Subkrunch crunchy topping (6 g), and Honey Mustard (3 g). None of these are large numbers alone, but they stack fast if you combine two or three.

What should you avoid at Subway on keto?

Any bread, wrap, or flatbread is the single biggest carb source at Subway — a 6" bread alone runs about 40 to 44 g total carbs, and a 12" wrap runs closer to 52 g, before any filling.¹ A handful of bowls also carry hidden sugar from their sauce even without bread.

• Sweet Onion Teriyaki Chicken Bowl — the teriyaki glaze pushes this to roughly 38 g net carbs, the highest of any bowl.
• Honey Mustard BBQ Chicken Bowl — about 27 g net carbs from the sauce alone.
• Meatball Marinara or Pepperoni Bowl — 30 g net carbs, mostly from the marinara.
• Veggie Patty Bowl — 25 g net carbs; the patty itself is high-fiber, but not low enough for a strict daily order.
• Cookies, chips, and soda — a Chocolate Chip Cookie alone runs about 27 g net carbs.

• Unsweetened iced tea or black coffee — 0 g net carbs.
• Total: roughly 10 to 17 g net carbs, well inside a strict keto day, with 45 to 55 g of protein to keep you full until your next meal.
