Keto at Chick-fil-A: 10 Menu Items Under 10g Carbs

Chick-fil-A has more keto-friendly options than almost any other fast food chain, and almost nobody orders them correctly.

That’s not an exaggeration. I’ve had clients come in frustrated after “doing keto” at Chick-fil-A for two weeks, then show me their order history: grilled nuggets plus a medium lemonade (45g carbs in the drink alone), or a side salad with the Honey Sesame dressing that adds 22g carbs. The food choices were fine. The hidden carbs wrecked them. So before we talk about what to order, let’s be precise about where the carbs are actually hiding.

Chick-fil-A’s nutrition data (publicly available on their website and verified as of July 2026) shows that their core grilled proteins are genuinely low-carb: the Grilled Chicken Sandwich fillet itself has 1g of net carbs. The bun adds 37g. That gap is where most people’s keto efforts quietly collapse.

The Numbers That Actually Matter

Let’s put the full picture in one place. I pulled these figures directly from Chick-fil-A’s nutrition calculator (July 2026), and I’ve organized them by net carbs because that’s what affects ketosis, not total carbs.

The lemonade number is the one that gets people. Forty-three grams of net carbs in a drink most people don’t even think about. A client of mine, a nurse from Portland who’s generally meticulous about food tracking, had been stalled for three weeks. We found it: a medium lemonade three or four times a week on her shift breaks. She switched to unsweetened iced tea. She dropped 4 lbs the following week. I can’t promise that result is typical, but the carb arithmetic was unambiguous.

What to Actually Order

Here’s how I think about Chick-fil-A keto ordering in tiers.

Tier 1: No-brainer, minimal customization needed. Grilled nuggets (8- or 12-count) with Zesty Buffalo Sauce or Honey Roasted BBQ (9g carbs in the BBQ, so go easy). Side salad without croutons. Unsweetened iced tea. Total for this meal: roughly 7-9g net carbs. You can eat this three times and stay on track. It’s not exciting, but it’s dependable.

Tier 2: Better meal, one careful customization. The Market Salad has a genuinely good flavor profile, but as served it has corn, blueberries, and a granola-nut blend that together add roughly 14g of unnecessary carbs. Ask for it without corn, without blueberries, without the granola blend. Add Avocado Lime Ranch dressing. You end up around 8g net carbs, with healthy fats from the dressing, real greens, and grilled chicken. The customization is dead simple and they’re used to it.

Tier 3: Works if you verify. The Cobb Salad is mostly keto-friendly as-is (no croutons needed, just skip them). Spicy versions of the grilled items have the same macros as the non-spicy. A Grilled Chicken Club without the bun or honey mustard is a reasonable choice.

One thing I’d tell anyone doing this for the first time: say “no bun, no sauce on the side” and then ask what sauces they have available. The crew will almost always just tell you. The Chick-fil-A app also lets you customize and see the updated nutrition in real time before you order, which I now recommend to every client before their first keto visit. Takes two minutes and removes most of the guesswork.

The Sauce Problem (It’s Bigger Than You Think)

Sauces deserve their own section because they’re where I see clients get sloppy. Chick-fil-A’s signature Chick-fil-A Sauce, which is what most people default to, has 13g of carbs per packet. It’s delicious. It’s also basically a sugar vehicle. Garden Herb Ranch has 1g per packet. Zesty Buffalo is 1g. Those are the two to remember.

The Honey Mustard is 11g. Polynesian Sauce is 13g. If you’re dipping a 12-count grilled nuggets in two packets of Polynesian, you’ve just added 26g of carbs to a 3g base. That’s a whole day’s carb budget for strict keto, in dipping sauce.

I’ve made this mistake myself. Early in my practice, I was testing Chick-fil-A options for a client presentation and grabbed two Polynesian packets out of habit. Realized partway through. It’s embarrassingly easy to do in the middle of a busy lunch.

Three Worked Examples

Scenario 1: Lunch under 10g net carbs with no special requests. Person orders 8-count Grilled Nuggets, a Side Salad (no croutons), and unsweetened iced tea. Picks up Garden Herb Ranch from the condiment station. Result: ~8g net carbs, 280 calories, solid protein at 26g. No customization required. Works at drive-thru.

Scenario 2: Higher fat, more satisfying, 15 minutes to customize. Person builds a Market Salad: grilled chicken, no corn, no blueberries, no granola blend, with Avocado Lime Ranch dressing. Orders two extra packets of Avocado Lime Ranch because one packet gets absorbed quickly into the greens. Result: ~11g net carbs, 510+ calories, 33g fat, 36g protein. Keeps you full for 5-6 hours.

Scenario 3: Where it goes wrong (and how to fix it). Person orders a Grilled Chicken Sandwich (bun on), thinking “grilled = keto,” plus a medium lemonade. Result: 38g net carbs from the bun + 43g from the lemonade = 81g net carbs. That’s not a keto meal, that’s a standard American lunch. Same items ordered correctly (fillet only, wrapped in lettuce if available, unsweetened tea) would be ~3g net carbs.

A Note on Electrolytes and Fast Food

This isn’t something you usually see in keto restaurant guides, but it matters. Chick-fil-A’s grilled items are relatively low in sodium compared to their breaded equivalents. The 8-count Grilled Nuggets have 440mg sodium; a comparable order of regular nuggets has nearly double. If you’re in the early weeks of keto, when sodium loss accelerates, you may actually want some salt with your meal. Throw a few pinches of table salt on your salad, or carry electrolyte packets like LMNT (affiliate link) and mix one into your water. Sounds minor. In practice, it’s the difference between a comfortable afternoon and a 3pm wall.
