Standard sweet relish is not ideal for keto, but it’s not off-limits either. One tablespoon of sweet relish contains about 5.3 grams of carbs, which adds up fast when your daily limit is 20 to 30 grams. Dill relish, on the other hand, is a much better fit, with roughly 1 gram of carbs per tablespoon. The type of relish you choose makes a real difference.
Sweet Relish: The Carb Problem
Sweet relish gets its flavor from added sugar, and it shows in the nutrition label. A single tablespoon packs 5.26 grams of carbohydrates, including 2.4 grams of sugar and almost no fiber (0.16 grams). That means the net carbs are essentially the same as the total carbs.
To put that in perspective, two tablespoons on a hot dog uses up more than a third of a strict 30-gram daily carb budget. Most people don’t measure relish carefully, so it’s easy to go over without realizing it. Traditional relish recipes call for significant amounts of sugar. Some recipes use nearly two cups of sugar for a batch, and commercial brands often include high-fructose corn syrup as well.
Can you technically fit sweet relish into a keto day? Yes, if you’re disciplined about portions and track everything else you eat. But it’s one of those foods where a small serving costs you a disproportionate chunk of your carb allowance for very little nutritional return.
Dill Relish: The Keto-Friendly Swap
Dill relish is made from cucumbers, vinegar, and spices without the heavy sugar load. A tablespoon typically contains around 0 to 1 gram of net carbs, making it essentially a free food on keto. You can use it generously on burgers, in tuna salad, or mixed into dressings without worrying about your carb count.
When shopping for dill relish, check the ingredients list anyway. Some brands sneak in small amounts of sugar even in their “dill” varieties. The nutrition panel should show close to zero grams of sugar per serving. If it does, you’re in the clear.
No-Sugar-Added and Keto Brands
If you prefer the sweeter taste of traditional relish, several brands now make no-sugar-added versions. Mt. Olive, for example, sells a No Sugar Added Sweet Relish sweetened with sucralose instead of sugar. These products give you the familiar sweet relish flavor with a fraction of the carbs.
When evaluating these products, look at the net carbs on the label rather than trusting the front-of-package marketing. “No sugar added” doesn’t always mean zero carbs, since the cucumbers and other vegetables in relish contain small amounts of natural carbohydrate. Still, most no-sugar-added relishes land between 0 and 2 grams of net carbs per tablespoon, which is a major improvement over the standard 5.3 grams.
Making Your Own Keto Relish
Homemade relish gives you complete control over the ingredients. The basic formula is simple: chopped cucumbers (or zucchini), vinegar, salt, spices, and a keto-friendly sweetener like monk fruit blend or allulose in place of sugar. One popular approach uses zucchini as the base, which has slightly fewer carbs than cucumber and takes on the same tangy, relish-like texture when pickled.
A typical keto relish recipe calls for about two-thirds of a cup of monk fruit sweetener for a full batch. Monk fruit and erythritol blends work well because they dissolve easily in the vinegar base and don’t leave a bitter aftertaste the way stevia sometimes can. The finished relish keeps in the refrigerator for several weeks, and you can process it in canning jars for longer storage.
The flavor won’t be identical to Heinz sweet relish, but most people find homemade versions satisfying once they’ve been on keto long enough for their taste preferences to shift. Adding a pinch of turmeric gives it the classic yellow-green color, and celery seed rounds out the flavor profile.
Quick Comparison by Relish Type
- Sweet relish (standard): ~5.3 g net carbs per tablespoon. High sugar content. Use sparingly or avoid on strict keto.
- Dill relish: ~0 to 1 g net carbs per tablespoon. No added sugar. Keto-friendly in normal portions.
- No-sugar-added sweet relish: ~0 to 2 g net carbs per tablespoon. Uses artificial or natural zero-calorie sweeteners. A solid middle ground.
- Homemade keto relish: Variable, but typically under 1 g net carbs per tablespoon when made with monk fruit or erythritol.
The bottom line is straightforward: skip the standard sweet relish or use it in truly tiny amounts, and reach for dill relish, a no-sugar-added brand, or a homemade version instead. A simple swap keeps the flavor on your plate without burning through your carb budget on a condiment.
