Paleo Ketchup Recipe Without Refined Sugar

The paleo diet asks a simple question about every food: could our ancestors have eaten this? Refined sugar, corn syrup, and chemical preservatives fail the test immediately — which rules out virtually every ketchup on the supermarket shelf. But tomatoes, vinegar, fruit, and spices are all paleo-friendly whole foods, so a proper paleo ketchup is entirely possible and honestly better tasting than the processed original. This paleo ketchup recipe uses no refined sugar at all. Instead, a little raw honey and the natural sweetness of roasted tomatoes do the sweetening, while warm spices and apple cider vinegar deliver the classic tang. In about 50 minutes you will have a clean-ingredient ketchup that works for paleo, Whole30-style eating (with the honey adjustment noted below), and anyone who simply wants a condiment made from food, not factories.

What Makes Ketchup “Paleo”?

A paleo condiment must avoid refined sugars, grains, legumes, dairy, and artificial additives. Commercial ketchup fails on multiple counts: most brands use high-fructose corn syrup or refined cane sugar, plus “natural flavors” and preservatives. This recipe keeps everything ancestrally simple — tomatoes, honey, vinegar, salt, and spices — with nothing you cannot pronounce. The one ingredient to check carefully is the canned tomatoes: choose a brand with no added calcium chloride or citric acid if you want to be strict.

Ingredients You’ll Need

This recipe makes about 1 1/2 cups (24 tablespoons). For strict Whole30 compliance, replace the honey with the same amount of date paste and skip the allspice if your rules exclude it.

• 2 lbs (900g) ripe tomatoes, halved — or one 28-oz can whole peeled tomatoes, no additives
• 1 medium red onion, chopped
• 3 cloves garlic, minced
• 1/2 cup apple cider vinegar (with the mother, unfiltered)
• 1/4 cup raw honey
• 2 tablespoons tomato paste (ingredients: tomatoes only)
• 1 teaspoon sea salt
• 1/2 teaspoon ground allspice
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon ground cloves
• 1/4 teaspoon cayenne pepper (optional)
• 1 bay leaf

Step-by-Step Instructions

1. Roast the tomatoes (optional but recommended). Toss the halved tomatoes, onion, and garlic with a drizzle of olive oil on a sheet pan. Roast at 400°F (200°C) for 25 minutes until the edges caramelize. This deepens the sweetness naturally.
2. Simmer the base. Transfer everything (including the pan juices) to a saucepan, or simply combine all ingredients in the pot if you skipped roasting. Add the vinegar, honey, tomato paste, sea salt, allspice, cinnamon, cloves, cayenne (if using), and bay leaf.
3. Cook it down. Bring to a gentle boil, then simmer on low, uncovered, for 30–40 minutes, stirring regularly, until thick and deeply red.
4. Blend smooth. Remove the bay leaf and blend with an immersion blender until completely smooth.
5. Strain for texture. Press through a fine-mesh sieve to remove seeds and skins.
6. Final reduction. Return to the pot and simmer 5–10 more minutes until it thickly coats a spoon. Remember it firms up slightly as it cools.
7. Cool and store. Cool completely and refrigerate in a clean jar for up to 3 weeks.

Tips for the Best Paleo Ketchup

Roasting is the secret weapon

When you cannot use refined sugar, you need another way to build sweetness and depth. Roasting the tomatoes and onions before simmering caramelizes their natural sugars and adds a smoky richness that raw tomatoes never achieve. Those 25 minutes in the oven are the single biggest flavor upgrade you can give this recipe.

Read your tomato labels

Many canned tomatoes contain calcium chloride (a firming agent) or citric acid. While not harmful, strict paleo eaters prefer tomatoes canned in their own juice with nothing added. San Marzano-style tomatoes packed in juice are usually the cleanest widely available option.

Sweeten to your taste at the end

Honey intensity varies by variety, and tomatoes differ in sweetness by season. Start with the listed 1/4 cup, then taste after the final reduction and add a teaspoon more if the ketchup tastes sharp. Small adjustments at the end are more reliable than guessing at the start.

Easy Variations to Try

• Date-sweetened: replace the honey with 1/3 cup date paste for a deeper, caramel-like sweetness.
• Smoky chipotle: add one dried chipotle pepper to the simmer (remove before blending) for gentle heat and smoke.
• Maple version: swap the honey for pure maple syrup — technically still paleo-friendly and deliciously different.
• Extra-spiced: add 1/2 teaspoon ground ginger and a pinch of nutmeg for a warmer, almost chutney-like profile.

How to Store Paleo Ketchup

Honey is a mild natural preservative, but this ketchup still needs refrigeration. Kept in a clean, airtight jar, it stays fresh for up to 3 weeks. For longer storage, freeze it in ice-cube trays and transfer the cubes to a freezer bag for up to 3 months. Because there are no stabilizers, a little separation after thawing is normal — just stir it back together.

Frequently Asked Questions

Is honey really paleo?

Most paleo guidelines accept raw honey as an unrefined, natural sweetener, though it is still sugar and should be used in moderation. Strict Whole30 eliminates all added sweeteners including honey, so use date paste or unsweetened ketchup during a Whole30 round instead.

Can I use this ketchup on a keto diet too?

The honey makes this version too carby for strict keto at 4.5 grams of carbs per tablespoon. If you eat keto, try our keto-friendly ketchup recipe, which uses erythritol or allulose for under 1 gram of net carbs per serving.

Why is my ketchup brown instead of red?

Honey and long roasting both darken ketchup more than refined sugar does. It is purely cosmetic — the flavor is actually deeper. If bright red color matters to you, skip the roasting step and reduce the simmer time slightly.

Is this ketchup safe for kids?

Yes — it is just tomatoes, honey, vinegar, and spices. Note that honey is not recommended for children under one year old, so wait until after their first birthday. Skip the cayenne for young kids.
