The lowest-carb crackers on the market come in at just 1 gram of net carbs per serving, while a standard serving of saltines packs about 11 grams. Your best options fall into a few categories: cheese-based crisps, seed-based crackers, and almond flour crackers, each with different textures and trade-offs worth knowing about.
How Low Carb Crackers Compare to Regular Ones
A typical serving of regular saltine crackers (about 3 to 5 crackers) contains roughly 11 grams of carbs and barely any fiber, leaving almost no difference between total and net carbs. That means even a modest handful can eat into a daily carb limit quickly, especially on a keto or low-carb diet where you’re aiming for 20 to 50 grams per day.
Low-carb crackers reduce that number through two strategies. Some replace grain flour entirely with ingredients like cheese, flaxseed, or almond flour. Others load up on fiber, which subtracts from total carbs to bring the net count down. The result is a range from 1 to 15 grams of net carbs per serving depending on the brand and base ingredient.
Cheese-Based Crisps: The Lowest Option
If your priority is the absolute lowest carb count, cheese crisps are hard to beat. Whisps Parmesan Cheese Crisps contain just 1 gram of net carbs in a 15-crisp serving, along with 9 grams of protein. They’re made almost entirely from baked cheese, so they deliver a satisfying crunch and salty flavor without any flour at all.
The trade-off is texture. Cheese crisps are thinner and more brittle than a traditional cracker. They work well with dips or on their own as a snack, but they won’t hold up the same way under a thick spread. They’re also higher in fat and sodium than other options, which is fine for most low-carb diets but worth noting if you’re watching salt intake.
Seed-Based Crackers: Low Carb With Extra Fiber
Flaxseed crackers sit in a sweet spot between very low carb and nutritionally dense. Flackers, one of the more widely available brands, lists 14 grams of total carbs per 8-cracker serving, but 8 of those grams come from dietary fiber. That brings the net carb count to about 6 grams. The high fiber content also helps you feel full longer and slows down blood sugar spikes compared to grain-based crackers.
Keto Naturals makes seed-based crackers that go even lower, with just 1 gram of net carbs per serving in both their Sea Salt and Cheddar & Onion flavors. These are specifically formulated for ketogenic diets and tend to have a denser, crunchier texture than flax crackers. They’re a good middle ground if you want something that feels more like a traditional cracker without the carb load.
Almond Flour Crackers: Closer to Traditional
Almond flour crackers are the closest in taste and texture to what you’re used to from regular crackers. Simple Mills Fine Ground Sea Salt Almond Flour Crackers are one of the most popular options in this category. However, they come in at 15 grams of net carbs per 17-cracker serving, which is actually higher than some people expect from a “healthier” cracker. That’s only slightly better than saltines.
Simple Mills crackers work well if you’re moderately reducing carbs or just avoiding processed grains. But if you’re on a strict keto diet, they’ll use up most of your daily carb budget in a single serving. Check the label carefully, because “almond flour” on the front of a box doesn’t automatically mean low carb.
Keto-Specific Brands Worth Trying
HighKey makes crackers specifically marketed for keto dieters, available in Sea Salt and Cheddar flavors, both at 4 grams of net carbs per serving. They strike a good balance between genuinely low carb counts and a flavor and crunch that’s closer to a real cracker than cheese crisps offer. For many people, 4 grams per serving is low enough to fit comfortably into a keto meal plan while still leaving room for other foods throughout the day.

What to Look for on the Label
Net carbs are what matter, not total carbs. To calculate them yourself, subtract the grams of dietary fiber from the grams of total carbohydrates. A cracker with 14 grams of total carbs but 8 grams of fiber has only 6 grams of net carbs, which is what your body actually absorbs as usable carbohydrate. Some labels also list sugar alcohols, which you can subtract the same way.
Watch for serving sizes that seem generous but are actually small by weight. A “17-cracker serving” sounds like a lot until you realize each cracker is tiny. Comparing by weight (in grams) across brands gives you a more honest picture. Also check for added sugars, which show up even in crackers labeled as keto-friendly, particularly in flavored varieties like cinnamon or everything seasoning.
Ingredient lists tell you a lot too. The best low-carb crackers rely on seeds (flax, sunflower, chia), cheese, or nut flours as their base. If wheat flour or rice flour appears in the first few ingredients, the carb count is almost certainly higher than you want, regardless of what the front of the package says.
