In just a few simple steps you can turn ripe, fresh tomatoes into a vibrant, healthier ketchup that tastes better, costs less, and lets you control every ingredient.
Why bother making it yourself? Because a jar of freshtomato ketchup means more lycopene, less junk, and the satisfaction of saying, I made that. Lets dive in, grab a cutting board, and get that sauce simmering.
Why Switch Ketchup
What makes freshtomato ketchup healthier than storebought?
Store brands rely on tomato concentrate, highfructose corn syrup, and a cocktail of preservatives. Fresh tomatoes bring a natural boost of lycopene, vitaminC, and potassium. When you control the sweetener, you can keep the glycemic load lowperfect for anyone watching blood sugar.
Does it really taste better?
Absolutely. Fresh tomatoes have a bright, gardengrown flavor that a processed concentrate cant mimic. By simmering the fruit slowly, you coax out a deep, caramelized sweetness that feels indulgent without the artificial aftertaste.

Core Ingredients List
Which tomatoes work best?
Plump plum or Roma tomatoes give you the right balance of flesh and acidity. If you love a sweeter profile, try cherry tomatoestheyll add a subtle honey note. I once tried canned paste and the flavor fell flat; fresh is the gamechanger.

Basic Easy Recipe
Stepbystep instructions
1 Prep the tomatoes
Wash, core, and roughly chop the tomatoes. Blend them in batches until you have a coarse puree. No need for a perfect texture; the simmering will smooth everything out.
2 Cook & reduce
Pour the puree into a saucepan. Add the vinegar, brown sugar, onion powder, garlic powder, and salt. Bring to a gentle boil, then lower the heat and let it simmer uncovered for 2030minutes, stirring every few minutes. The sauce should thicken and darken.
3 Adjust & finish
Taste it. If you crave more tang, add a splash of extra vinegar. Want extra sweetness? Stir in a bit more brown sugar or maple syrup. For an ultrasmooth finish, blend again for a minute.
4 Cool & store
Let the ketchup cool to room temperature, then transfer it to sterilized jars. Refrigerated, it keeps for up to two weeks. If you want it to last longer, follow the canning steps below.

Troubleshooting & FAQs
Why is my ketchup watery?

How can I make it thicker without cornstarch?
Incorporate a tablespoon of chia seeds or cooked quinoa. Both absorb liquid and add a subtle boost of fiberhealthy and zerogummy.
Can I use a different vinegar?
Yes! White wine vinegar gives a milder tang, while apple cider vinegar adds a fruity note. Just keep the total acidity at about 5% for safe canning.

Expert Tips & Resources
Pro chefs secret: roast the tomatoes
Before blending, spread the chopped tomatoes on a baking sheet, drizzle with a teaspoon of olive oil, and roast at 200C for 15minutes. The caramelization adds depth that boiling alone cant achieve.
Best containers for longterm storage
Mason jars with twopiece lids are ideal. Avoid plastic because the acidity can leach chemicals over time. Sterilize jars by boiling them for 10minutes before filling.
