Paleo & Keto Ketchup
An Instant Hack
If you’ve ever given up ketchup because of sugar and filler ingredients, this approach is for you. Start with a high-quality unsweetened ketchup made from tomatoes, vinegar, and a blend of spices. These products are short on additives and heavy on flavor, giving you a clean base that only needs a touch of sweetener if you prefer a sweeter profile.
Why Unsweetened Works
Many “sugar-free” ketchups contain sugar alcohols like maltitol or other sugar substitutes that can cause digestive discomfort for some people. By choosing an unsweetened ketchup with minimal ingredients, you avoid those additives and keep the ingredient list simple and transparent: tomatoes, balsamic or apple cider vinegar, salt, and spices. The natural tomato flavor often offers surprising sweetness on its own, especially to those accustomed to low-sugar eating.
Choosing a Sweetener
If you want your ketchup slightly sweeter to match the classic taste profile, use a powdered low-carb sweetener. Powdered sweeteners blend more smoothly into sauces than liquid sweeteners or coarse crystals. Common powdered options include allulose, erythritol, powdered xylitol (use caution around pets), or powdered monk fruit blends. Allulose is popular because it has little to no aftertaste for many people, while erythritol can produce a mild cooling effect.
To make powdered sweetener at home, pulse your preferred granulated sweetener in a dry blender or food processor until it becomes a fine powder. Let the dust settle before opening the machine. If you use a pre-mixed powdered sweetener, remember to adjust for relative sweetness—some blends are significantly sweeter than others.

Serving Suggestion
- Serve with keto-style fries, roasted vegetables, or as a dipping sauce for grilled meats.

- Stir well until fully incorporated. Taste and adjust sweetness as desired. That’s it — enjoy immediately.
Notes
*Prices for unsweetened ketchups vary depending on brand and store, so shop around for the best value. Powdered sweeteners will blend more smoothly than granulated versions.
When using xylitol, be extremely careful around dogs and other pets — xylitol is toxic to them.
Storage & Tips
Store any unused ketchup in a sealed container in the refrigerator. Small batches are easy to make and remain fresh for several days. If the sauce separates slightly after chilling, stir or whisk to recombine. For a deeper flavor, let the mixed ketchup rest in the fridge for an hour to allow the flavors to meld.
