Homemade Ketchup

Recipe by  

"This ketchup does come close to those name brands in terms of taste, texture and color. I've never had a tomato paste-based ketchup that I liked, so I decided to cook down crushed tomatoes instead. By using the slow cooker, we take most of the labor out of the process."

Directions

  1. Pour ground tomatoes into slow cooker. Swirl 1/4 cup water in each emptied can and pour into slow cooker. Add sugar, vinegar, onion powder, garlic powder, salt, celery salt, mustard powder, black pepper, cayenne pepper, and whole clove; whisk to combine.
  2. Cook on high, uncovered, until mixture is reduced by half and very thick, 10 to 12 hours. Stir every hour or so.
  3. Smooth the texture of the ketchup using an immersion blender, about 20 seconds.
  4. Ladle the ketchup into a fine strainer and press mixture with the back of a ladle to strain out any skins and seeds.
  5. Transfer the strained ketchup to a bowl. Cool completely before tasting to adjust salt, black pepper, or cayenne pepper.

Wow! This recipe came out great. I have two little kids and wanted to make a ketchup without high fructose corn syrup, and to use in our homemade BBQ and sloppy joe sauces. It tastes just like the bottled stuff. I skipped the white sugar & put in 1/3 c of honey instead, to make it even less processed. Canned crushed tomatoes made it easier to strain at the end, and the consistency is pretty good. I would skip the added water next time when using the honey. This is a keeper! I'm so excited that I found this recipe & it was so easy using the slow cooker.

Not sure if anyone else has answered the cayenne pepper amount, I would only give a very few shakes for this 3-cup batch. Have not tried this but I am planning to do so today. I gave it a 3 star rating because it reads like it would be a good substitute for bottled Ketchup. Once I have made it, and if I like the results I'll come back and change the rating. For C.J. who asked about making this recipe in bulk and water-bath canning, please check: http://www.bernardin.ca/pages/recipe_page/51.php?pid=521 I hope posting this link is not against any rules, I am not affiliated with Bernardin in any way, I was aware of this bulk recipe and wanted to share it.

This turned out great! I used minced green onions, garlic, and celery instead of the garlic powder, onion powder, and celery salt. I didn't puree it because I kind of like the chunky consistency. I think next time I will try peeled pureed tomatoes and cut the sugar a bit. All in all, easy and delicious!

This reminds me of really good BBQ sauce! It was very sweet. I would like to also try it with less sugar. I used a saucepot instead which sped up the cooking process so I don't know what difference that made. You could get away without peeling the skin and straining the mixture. It would just be chunky if you like that texture.

Chef John loved your video! I too am one more fool by making homemade ketchup, and I must say I'm sure glad I did it with your recipe. I used my own homegrown tomatoes, mashed and strained them with my "Sauce Master" so I simply measured 28oz twice (8 cups) then doubled that as I had 30 cups of puree to use up. Spices & seasonings are just right. Thanks again Chef John! Now at least I can say I've made h/m ketchup lol.

I do a couple things just a little differently. I made a gallon, and froze the extra. Let me say that my Favorite Ketchup by Far- is the recipe for fermeted ketchup in Nourishing Traditions. It's EASY and tastes better than anything you can fathom when thinking Ketchup. But I hate to cook a fermented food and I needed a cookable Ketchup for BBQ Sauce. So- I made this, and it turned out great- but I carried over some ideas from my favorite Ketchup. To the Gallon I used 1/2 cup Fish Sauce, skipped the clove, and used 1 cup honey in place of 2 cups sugar. I used some red wine and some white wine vinegar (just because it's what I had)- it turned out as good as Heinz, and Almost as good at the Fermented stuff I make from NT. Good stuff- no corn syrup, no junk. Also, if you used strained tomatoes you don't have to strain when you're done. Just put all the ingredients in the crock pot, leave the lid off and it's done in a few hours. Worth it- as long as you make a lot and freeze the extra.

Have not tasted it post-cooking, but it smells and tastes like good ketchup as it is cooking! Just wanted to note that the ingredient list does not include cayenne, yet the directions call for adding cayenne. Perhaps other reviewers have already noted this. I had to guess at the amount.

Thank you for this fantastic recipe! I've been looking to provide my family with heart healthy options in the way of ketchup (we love our ketchup)! Have tried many and have not been able to consume more than the first few bites of any of them! I made this less than a month ago and we are on our last few drops! I did make a few changes: swapped out the white sugar for 1/2 the amount in Truvia, crushed tomatoes instead of ground, Pink Sea Salt crystals for the table salt, and finally... left out the celery salt only because I didn't have it on hand nor find it anywhere to buy (didn't even know it existed). Got started late in the day; forgot about it cooking in the slow cooker (thankfully on low) and went to bed. Woke up Sunday morning to the most fantastic aroma wafting throughout my house! UNTIL I realized... OMG! MY KETCHUP! It turned out great though! Making second batch with the changes above and found the celery salt! Thank you so much for your hard work in putting this together for all of us to enjoy!
