Keto at Taco Bell: The Best Low-Carb Order
The best keto order at Taco Bell is a Cantina Chicken Bowl built with no rice and no beans — chicken, cheese, sour cream, guacamole, and pico de gallo — landing around 9 g net carbs. Prefer no substitutions? Two Crunchy Tacos run about 20 g net carbs exactly as ordered.
Menu data last verified: August 2026, sourced from Taco Bell's published nutrition figures via FastFoodNutrition.org.1 Taco Bell rotates its lineup often and nutrition can vary slightly by location and portion, so treat these numbers as a reliable planning guide, not a lab-certified count — confirm anything critical in the Taco Bell app before you order.
Taco Bell doesn't run a keto menu, and almost everything on it is built around a flour or corn tortilla, a hard shell, or a scoop of seasoned rice — the three biggest carb sources on the board. That's not a dead end, though: the chain is used to customization requests, and a handful of real menu items already sit under 20 g net carbs with zero changes. This guide breaks every item's net carbs into a heading you can scan at the counter, one ranked table, and four sample orders under 20 g.
What's the best keto order at Taco Bell?
Order a Cantina Chicken Bowl and ask for no rice and no beans — the bowl already comes with chicken, cheddar cheese, sour cream, pico de gallo, guacamole, lettuce, and purple cabbage, so removing the two highest-carb ingredients leaves a fat-and-protein-forward bowl at roughly 9 g net carbs. It's the closest thing Taco Bell has to a build-your-own keto plate.
How do you order keto at Taco Bell — the standard mods?
Four swaps cover almost every keto order at Taco Bell: hold the tortilla or shell, skip the rice, skip the beans, and ask for extra cheese, sour cream, or guacamole in their place. These same four moves work across tacos, burritos, quesadillas, and bowls, so you can apply them to nearly anything on the menu.
- Ask for it "in a cup" or "no shell/tortilla." Taco Bell staff regularly build tacos and burritos without the shell or tortilla on request — you get the seasoned meat, cheese, lettuce, and sauce loose, which strips out most of the item's carbs in one move.
- Say "no rice, no beans" on any bowl or burrito. Rice and beans are the two biggest carb contributors in the Cantina Chicken Bowl and every burrito; removing both is the single highest-leverage swap on the menu.
- Add extra cheese, sour cream, or guacamole instead. All three are near-zero-carb, high-fat toppings that replace the volume and satisfaction rice and beans would have added.
- Choose a protein and don't worry about it. Seasoned beef, shredded chicken, and steak are all effectively carb-free on their own — the shell, tortilla, rice, and beans are what add carbs, not the meat.

Which tacos and roll-ups are lowest in net carbs?
A Crunchy Taco is Taco Bell's lowest-carb whole menu item at 10 g net carbs, and the Cheesy Roll-Up isn't far behind at 13 g — both work without any modification if you'd rather order off the board than customize.
Crunchy Taco — 10g net carbs
Seasoned beef, lettuce, and cheddar in a hard corn shell. At 170 calories and 13 g total carbs minus 3 g fiber, it's the single lowest-carb whole item on the menu.1
Cheesy Roll-Up — 13g net carbs
A flour tortilla melted with a three-cheese blend, no meat or filling. Simple, fast, and one of the few sub-15 g items with no modification needed.
Soft Taco, Beef — 14g net carbs
Seasoned beef, lettuce, and cheddar in a soft flour tortilla. Slightly higher carbs than the Crunchy Taco because the flour tortilla holds more carbs than the hard shell.
MexiMelt — 18g net carbs
Seasoned beef, a three-cheese blend, and pico de gallo melted between two small tortillas. At 21 g total carbs and 3 g fiber, it just clears the under-20 g bar on its own.
Which burritos, chalupas, and specialties should you skip or modify?
Burritos, chalupas, the Mexican Pizza, and the Crunchwrap Supreme all carry 29 g net carbs or more, because each one stacks a tortilla or shell on top of rice or beans. Order these "no shell/tortilla, no rice, no beans" or skip them for a taco-based order instead.
Chalupa Supreme, Beef — 29g net carbs
A fried flatbread shell that's higher-fat than a taco shell but also higher-carb — 33 g total carbs and 4 g fiber. Order it "no shell" and you're left with mostly beef, cheese, and sour cream.
Tostada — 22g net carbs
A flat corn tostada shell topped with beans, lettuce, cheese, and red sauce. The 8 g of fiber softens the carb hit, but the shell and beans still add up.
Mexican Pizza — 39g net carbs
Two fried tortillas layered with seasoned beef, refried beans, cheese, and red sauce. Two tortillas plus beans make this one of the highest-carb items on the entire menu.
Crunchwrap Supreme — 65g net carbs
A large flour tortilla wrapped around a tostada shell, beef, nacho cheese sauce, lettuce, tomato, and sour cream. At 71 g total carbs, it's Taco Bell's single highest-carb item — skip it entirely on keto.
Can you make the Cantina Chicken Bowl keto?
Yes — the Cantina Chicken Bowl is Taco Bell's best keto customization base, but only after you remove the rice and beans; ordered as-is, the standard bowl runs 33 g net carbs, mostly from a scoop of seasoned rice.
Cantina Chicken Bowl, standard build — 33g net carbs
Seasoned rice, slow-roasted chicken, black beans, avocado ranch sauce, sour cream, lettuce, purple cabbage, pico de gallo, guacamole, and cheddar cheese. At 44 g total carbs and 11 g fiber, the rice and beans account for the bulk of it.2
Cantina Chicken Bowl, no rice or beans — about 9g net carbs (customized)
Removing the rice and beans strips out roughly 24 g net carbs, leaving chicken, cheese, sour cream, guacamole, pico de gallo, and lettuce/cabbage. This is an editorial estimate built from the standard bowl's published macros and the black beans/guacamole side listings, not a figure Taco Bell publishes directly — confirm your exact build in the app before relying on it for a strict daily budget.
Which sides and extras keep net carbs lowest?
Guacamole and black beans are Taco Bell's two standalone sides, and only guacamole is genuinely low-carb — black beans still carry 5 g net carbs per order, and the combo sides (chips with cheese sauce) run much higher once the chips are counted.
Guacamole (side) — 2g net carbs
A small 21 g side portion at 35 calories and 2 g total carbs. The best fat-forward add-on for any customized bowl or taco order.
Black Beans (side) — 5g net carbs
50 calories, 8 g total carbs, 3 g fiber. Reasonable in small amounts, but it's the ingredient you're removing from the Cantina Chicken Bowl to hit 9 g net carbs.
Chips and Nacho Cheese Sauce — 22g net carbs
220 calories, 24 g total carbs, 2 g fiber. The cheese sauce itself is fine on keto; it's the fried corn chips carrying almost all of this item's carbs.

Sample orders under 20g net carbs
- Cantina Chicken Bowl, no rice or beans (about 9 g net carbs): chicken, cheese, sour cream, guacamole, pico de gallo, lettuce, and purple cabbage.
- Crunchy Taco + Guacamole side (about 12 g net carbs): the lowest-carb whole taco on the menu plus a fat-forward side.
- Cheesy Roll-Up + Guacamole side (about 15 g net carbs): a fast, simple order with no modifications beyond adding the side.
- Crunchy Taco + Black Beans side (about 15 g net carbs): a solid option if you'd rather have a bean side than guacamole.

What should you avoid at Taco Bell on keto?
Skip the Crunchwrap Supreme, Mexican Pizza, and anything with two tortillas or a tortilla plus rice or beans — those combinations stack Taco Bell's three biggest carb sources on top of each other and routinely run 30 to 65 g net carbs in a single item.
Also watch the drinks: Baja Blast and other Mountain Dew-based Freezes and fountain drinks are loaded with sugar and carry far more net carbs than anything on the food menu. Order unsweetened iced tea, diet soda, or water instead.
How do you order keto at the Taco Bell app or drive-thru?
The Taco Bell app lets you customize any item — remove rice, beans, tortilla, or shell, and add extra cheese, sour cream, or guacamole — before you check out, which is the easiest way to lock in your modifications without a mix-up at the register.
If you're ordering at the counter or drive-thru, say "no rice, no beans, extra cheese and sour cream" up front — most keto ordering mistakes at Taco Bell happen when rice or beans get added by default because no substitution was requested. Run your final build through the net-carb calculator if you're stacking sides and want an exact number before you order.
