In this tutorial, I will teach you how to make ketchup at home, starting from either fresh tomatoes or from tomato paste--your choice!

Nothing beats the tangy delicious flavor of a ripe tomato paired with the perfect blend of sweet and spice. The best part? This recipe for the condiment is quick and easy, so no waiting around to top your juiciest hamburger or freshest batch of perfectly-salted French fries.
There is no need to fill your body with unnecessary preservatives or potentially harmful ingredients knowing ketchup is this easy to make at home.
Try it on these ground bison burgers or serve it with a batch of Cajun fries (check out how to make Cajun fries here). Those are two of my favorite ways to use the condiment.
Choose tomato paste for a quicker version without the need to strain the mixture, or...make the ketchup with your own fresh tomatoes for a more from-scratch version.

Make Ketchup With Fresh Tomatoes
Ingredients
- fresh Roma tomatoes - The darker the color, the better. To me, the best tomatoes for making ketchup are ripe Roma tomatoes. They are meaty, have a low moisture content, a low amount of seeds and a rich flavor when cooked down.
- red wine vinegar - To add that classic ketchup tang.
- brown sugar - To enhance the flavor and texture. It also adds a deeper color, making the ketchup look more appealing.
- Worcestershire sauce - A thin brown sauce that adds complex flavor.
- salt and pepper - To taste.
*Check recipe card for ingredient amounts.
Chef's Note: Like it hot? Add a little spice with some cayenne or hot sauce. Don’t be afraid to play around with the ingredients.
Instructions
Step #1. If you’re going to start with fresh tomatoes, place them in a saucepan with vinegar, sugar, Worcestershire sauce, salt and pepper.
Step #2. Simmer until it thickens and most of the liquid has evaporated (at least 25 minutes).
Step #3. Purée the fresh tomato mixture in a blender, until smooth.
Step #4. Strain the ketchup using a fine mesh sieve. If it is too thin for your liking, return it to the pot and simmer it down further, until desired thickness.
Chef's Note: At this point, adjust the seasoning with the salt and pepper if needed. Let it cool and it's ready to use!

Recipe FAQs
While ketchup was originally made without tomatoes (instead using oysters, mushrooms, peaches, etc.) and appeared in British cookbooks in the 18th century, the tomato ketchup version only started to appear in 19th century cookbooks and included anchovies. If you want to go way back, the precursor to ketchup was actually a Chinese fermented fish sauce in 300 B.C. They called it “ge-thcup” or “koe-cheup”.
While we can't pinpoint who the inventor of the original ketchup was, James Mease is credited with inventing the first tomato ketchup recipe in the early 1800s. He was a scientist from Philadelphia. Heinz came out with their own recipe in 1876 and are one of the most well known ketchup brands today.
To thicken homemade ketchup, gently simmer it in a saucepan until desired consistency.
