Sugar Free Catsup: The Best Keto and Low-Carb Catsup Options in 2026

Traditional catsup is loaded with sugar — a single tablespoon of Heinz contains 4 grams, and most people use far more than a tablespoon at a time. For anyone following a keto diet, managing diabetes, or simply trying to reduce sugar intake, sugar free catsup has gone from a niche curiosity to an essential pantry staple. The good news is that the keto catsup market has matured significantly, and today’s best low sugar catsup and low carb catsup options taste remarkably close to the real thing. In this comprehensive guide, we review the top sugar-free catsup brands, compare their ingredients and flavors, and help you find the perfect option for your dietary needs.

Why Regular Catsup Is a Problem for Low-Carb Diets

Most people do not realize just how much sugar is hiding in their catsup. A standard serving of mainstream catsup brands like Heinz, Hunt’s, or Del Monte contains approximately 4 grams of sugar per tablespoon. That might not sound like much, but consider these realities:

• Most people use 2-4 tablespoons per meal, adding 8-16 grams of sugar (and corresponding carbs) per sitting
• On a strict keto diet limited to 20 grams of net carbs per day, a generous serving of regular catsup can consume nearly half your daily carb allowance
• Sugar from catsup adds up over time — a family that uses catsup daily can easily consume several pounds of added sugar annually from catsup alone
• The sugar in catsup can cause blood glucose spikes that are problematic for people with diabetes or insulin resistance

This is why the market for sugar free catsup, keto catsup, low sugar catsup, and low carb catsup has exploded. Consumers want the familiar taste and convenience of catsup without the metabolic consequences.

Best Sugar Free Catsup Brands Reviewed

1. Primal Kitchen Organic Unsweetened Ketchup — Best Overall

Primal Kitchen leads the sugar free catsup category with a product that contains zero added sweeteners of any kind. Instead of using sugar substitutes, Primal Kitchen relies on the natural sweetness of organic tomatoes and the complexity of organic balsamic vinegar to create a ketchup that is satisfying without any added sugar.

Nutrition per tablespoon: 10 calories, 0g added sugar, 1g total carbs, 1g net carbs

Sweetener used: None — completely unsweetened

Why we love it: This is the cleanest option on the market. No artificial sweeteners, no sugar alcohols, no stevia — just tomatoes, vinegar, and spices. It is Whole30 approved, paleo-friendly, and perfect for strict keto catsup dieters. The balsamic vinegar provides a rich depth that partially compensates for the missing sweetness. The taste is more savory and tangy than traditional catsup, which takes some adjustment, but most people grow to prefer it.

2. G Hughes Sugar Free Ketchup — Best Tasting Sugar Free Option

G Hughes has built a loyal following in the low carb catsup space by creating products that taste remarkably close to their full-sugar counterparts. Their sugar-free ketchup is often cited as the best-tasting option for people who want the classic catsup experience without the carbs.

Nutrition per tablespoon: 10 calories, 0g sugar, 2g total carbs, 1g net carbs

Sweetener used: Sucralose

Why we love it: If your primary goal is finding a sugar free catsup that tastes like regular catsup, G Hughes is hard to beat. The flavor is sweet, tangy, and tomato-rich in all the ways you expect. The main trade-off is that it uses sucralose (Splenda) as a sweetener, which some health-conscious consumers prefer to avoid. But for pure taste satisfaction, G Hughes is the top performer in blind taste tests.

3. Heinz No Sugar Added Ketchup — Best Mainstream Option

Heinz offers a No Sugar Added variety that brings the familiarity of the Heinz brand to the low sugar catsup market. For Heinz loyalists who need to cut sugar, this is the path of least resistance.

Nutrition per tablespoon: 10 calories, less than 1g sugar, 2g total carbs, 1g net carbs

Sweetener used: Sucralose

Why we love it: Heinz No Sugar Added captures approximately 80 percent of the classic Heinz catsup flavor. It is slightly less sweet and slightly more vinegary than the original, but the tomato base and spice profile are unmistakably Heinz. The biggest advantages are availability and brand trust — you can find this at virtually every grocery store, and the Heinz name provides reassurance of quality. Like G Hughes, it uses sucralose, so this is not an option for people who avoid artificial sweeteners.

4. AlternaSweets Ketchup — Best Stevia-Sweetened Option

For consumers who want a low carb catsup but prefer natural sweeteners over artificial ones, AlternaSweets uses stevia leaf extract as its sweetener. This puts it in a unique position in the market — sweet enough to taste like traditional catsup but made without sucralose, aspartame, or other artificial sweeteners.

Nutrition per tablespoon: 10 calories, 0g added sugar, 1g total carbs, 1g net carbs

Sweetener used: Stevia leaf extract

Why we love it: AlternaSweets strikes a good balance between clean ingredients and a familiar flavor profile. Stevia can sometimes impart a bitter or licorice-like aftertaste, but AlternaSweets has managed to formulate their ketchup in a way that minimizes this issue. It tastes sweet and tomatoey with just a hint of the stevia character that most people will not notice, especially when eating it with food.

5. True Made Foods Vegetable Ketchup — Best Naturally Low Sugar

True Made Foods takes a unique approach to the low sugar catsup challenge. Instead of using sugar substitutes, they replace a significant portion of the sugar with pureed vegetables — specifically butternut squash, carrots, and spinach. The result is a ketchup with about 50 percent less sugar than traditional brands, with the missing sweetness provided naturally by the vegetables.

Nutrition per tablespoon: 15 calories, 2g sugar, 3g total carbs, 3g net carbs

Sweetener used: Reduced sugar, supplemented with vegetable purees

Why we love it: While not technically sugar-free, True Made Foods is the best option for people who want significantly reduced sugar without any artificial or alternative sweeteners. The vegetable purees add nutritional value and a subtle complexity to the flavor. It tastes remarkably like regular catsup — most people cannot detect the vegetables at all. This is also an excellent choice for sneaking extra vegetable servings into your children’s diet.
