Subway Keto Options 2026: Complete Low-Carb Ordering Guide
Yes, you can eat keto at Subway. The best Subway keto options are protein bowls and chopped salads — both skip the bread and keep you under 10g net carbs. Top picks include the Rotisserie Chicken Protein Bowl (6g net carbs, 31g protein), Tuna Salad (5g net carbs, 15g protein), and Chicken & Bacon Ranch Salad (5g net carbs, 30g protein). Stick with oil & vinegar or mayo for dressing, load up on low-carb veggies like spinach, peppers, and olives, and avoid all breads, wraps, sweet sauces, and meatball marinara.
Subway and keto sound like they shouldn’t go together. The whole restaurant is built around bread — it’s literally a sandwich shop. But most people miss: Subway is also one of the most customizable fast-food chains in the world. And once you learn how to work the menu, it becomes one of the easiest places to eat low-carb.
The trick is simple: skip the bread, order a protein bowl or salad, choose the right sauces, and load up on low-carb veggies. That’s it. No special requests, no awkward conversations, no weird looks from the employee behind the counter. This guide covers every Subway keto option available in 2026 — what to order, what to avoid, and exactly how many net carbs you’re getting.

The 4 Golden Rules of Keto at Subway
Before we get into specific menu items, here are four rules that make keto ordering at Subway foolproof. Follow these and you’ll stay under 10g net carbs on almost any order.
Rule 1: No Bread. No Wraps. No Flatbread.
This is the big one. Every Subway bread option — Italian, wheat, multigrain, herbs & cheese, flatbread — has 35–47g of carbs per 6-inch serving. That’s your entire daily keto carb limit in one piece of bread. Wraps aren’t better — a single Subway wrap shell has around 35g carbs. The solution? Order a protein bowl or a chopped salad instead. Same fillings, zero bread.
Rule 2: Watch the Sauces
This is where hidden carbs sneak in. Sweet Onion Teriyaki sauce has 7g of sugar per serving. Honey Mustard has 6g. BBQ sauce? Even worse. Stick with oil & vinegar (0g carbs), mustard (0g), mayo (0g), or ranch (1g). We’ll cover every sauce below.
Rule 3: Load Up on Low-Carb Veggies
Almost every Subway vegetable is keto-friendly. Spinach, lettuce, cucumbers, green peppers, olives, pickles, jalapeños — all have under 1g net carbs per serving. The ones to be careful with are onions (slightly higher in carbs) and banana peppers (still low, but add up if you go heavy). Tomatoes are fine in moderation.
Rule 4: Add Cheese and Extra Meat for Fat & Protein
On keto, you need fat. Subway’s cheese options add healthy fat with nearly zero carbs. American, provolone, pepper jack, Swiss, cheddar, and mozzarella are all 0g net carbs. Adding extra meat or double meat boosts protein and fat without adding carbs. This is how you turn a light salad into a filling keto meal.
Subway Keto Options: Best Protein Bowls
Protein bowls are the easiest Subway keto option. They’re basically a footlong sandwich dumped into a bowl without the bread — all the meat, cheese, veggies, and sauce on a bed of lettuce. They’re filling, high in protein, and most have under 12g net carbs.
| Protein Bowl | Calories | Fat | Protein | Net Carbs |
|---|---|---|---|---|
| Rotisserie Chicken | 220 | 8g | 31g | 6g |
| Oven-Roasted Turkey | 160 | 2.5g | 25g | 8g |
| Steak & Cheese | 380 | 19g | 42g | 8g |
| Black Forest Ham | 160 | 3g | 18g | 9g |
| Tuna | 550 | 47g | 26g | 5g |
| Cold Cut Combo | 260 | 16g | 20g | 9g |
| Spicy Italian | 550 | 45g | 24g | 5g |
| Chicken & Bacon Ranch | 610 | 28g | 30g | 6g |
| Italian B.M.T.® | 550 | 45g | 24g | 9g |
| Veggie Patty | — | — | — | 41g ⚠️ |
The best overall keto bowl? The Rotisserie Chicken Bowl at just 6g net carbs with 31g protein. It’s high in protein, low in fat, and leaves plenty of room for a keto-friendly dressing without breaking your carb limit. The Tuna Bowl is also excellent if you need more fat — 47g fat and only 5g net carbs.
Best Keto Salads at Subway
Any Subway sandwich can be turned into a chopped salad. Just tell the employee “make it a salad” instead of choosing bread. The fillings get chopped up and tossed onto a bed of lettuce with your choice of veggies and dressing.
Salads tend to have slightly lower calories and carbs than protein bowls because they include less meat (6-inch portion vs. footlong). Here are the best options.
| Salad (no dressing) | Calories | Fat | Protein | Net Carbs |
|---|---|---|---|---|
| Chicken & Bacon Ranch | 430 | 32g | 30g | 5g |
| Spicy Italian | 270 | 22.5g | 11g | 3g |
| Tuna | 310 | 24g | 15g | 6g |
| Steak & Cheese | 210 | 9g | 21g | 8g |
| Rotisserie Chicken | 150 | 5g | 18g | 7g |
| Oven-Roasted Turkey | 110 | 2g | 14g | 7g |
| Italian B.M.T.® | 240 | 15g | 14g | 8g |
| Veggie Delite | 50 | 1g | 3g | 5g |
The Spicy Italian salad has the lowest net carbs at just 3g, plus 22.5g of fat — which is exactly what you need on keto. For more protein, go with the Chicken & Bacon Ranch salad at 30g protein and 5g net carbs. Want the fewest calories? The Veggie Delite salad is only 50 calories with 5g net carbs — add some olive oil and cheese to boost the fat.
Keto Breakfast at Subway
Subway’s breakfast menu works on keto — you just need to skip the bread and flatbread. Ask for your breakfast in a bowl or just request the fillings without any bread. Here are the keto-friendly breakfast options.
| Breakfast Item (no bread) | Calories | Fat | Protein | Net Carbs |
|---|---|---|---|---|
| Egg & Cheese (bowl) | 160 | 14g | 11g | 3g |
| Bacon, Egg & Cheese (bowl) | 190 | 12g | 16g | 4g |
| Steak, Egg & Cheese (bowl) | 220 | 14g | 19g | 5g |
| Ham, Egg & Cheese (bowl) | 180 | 10g | 17g | 4g |
| Sausage, Egg & Cheese (bowl) | 260 | 20g | 16g | 4g |
Every single breakfast option stays under 5g net carbs when ordered without bread. The Sausage, Egg & Cheese is the best keto breakfast pick because it has the most fat (20g) which keeps you full until lunch. Add some spinach and peppers for extra fiber and nutrients.
Keto-Safe Sauces & Toppings at Subway
Choosing the wrong sauce can blow your carb budget for the entire day. Here’s the complete list, split into safe and unsafe.
Keto-Friendly Sauces (under 2g carbs)

Sauces to Avoid on Keto

| Honey Mustard | 30 | 6g | 6g |
| BBQ Sauce | 35 | 7g | 8g |
| Sweet Chili | 40 | 8g | 9g |
Keto-Friendly Toppings (all under 1g net carbs)
Spinach, lettuce, cucumbers, green peppers, olives, pickles, jalapeños — all free, all keto-safe. Onions and tomatoes are slightly higher (about 1g carbs per serving) but still fine in normal amounts. Add extra cheese (0g carbs) or bacon (1g carbs for 2 strips) to boost fat and protein.

Does Subway have low-carb bread?
As of 2026, most Subway locations do not offer low-carb bread as a regular menu item. Some locations have previously carried Hero Bread (1g net carbs), but availability is limited and not guaranteed. Your best bet is to order a protein bowl or salad instead of relying on low-carb bread being available.
Are Subway protein bowls keto-friendly?
Most protein bowls are keto-friendly, with net carbs ranging from 5g to 9g. The exceptions are bowls with sweet sauces (like Sweet Onion Teriyaki) and the Veggie Patty bowl (41g carbs). Stick with meat-based bowls and keto-safe dressings.

How do I order keto at Subway without feeling awkward?
It’s completely normal. Just say “Can I get a [sandwich name] as a protein bowl?” or “Can I get that as a chopped salad?” The employees make these all day long — it’s a standard menu option, not a special request. You can also order through the Subway app, where protein bowls and salads are listed as regular options alongside sandwiches.
Is Subway better than other fast food for keto?
Subway is one of the best fast-food chains for keto because of its full customization. Unlike McDonald’s or Burger King where you’re modifying a fixed menu item, Subway lets you build every component of your meal from scratch. You control the protein, fat, carbs, and sauce at every step. The only chains that compare are Chipotle and certain salad-focused restaurants.
How many net carbs should I stay under on keto?
Most standard keto diets limit net carbs to 20–50g per day. “Net carbs” means total carbohydrates minus fiber. At Subway, most keto-friendly bowls and salads have 3–9g net carbs per meal, which fits comfortably within even the strictest 20g daily limit.

Yes. Order any sub as a protein bowl (no bread) to cut 40-50g carbs. The best keto options are Turkey Breast bowl (90 cal, 3g carbs), Rotisserie Chicken bowl (170 cal, 3g carbs), and any chopped salad with oil and vinegar.
