Homemade Gluten-Free and Corn-Free Ketchup

"Perhaps the hardest part of a gluten-free, corn-free diet is the inability to find ketchups on the grocer’s shelves that are safe to use. Here is a recipe that will take less than 1/2 hour to prepare and will keep in the refrigerator for several months. It is idiot-proof, I promise, and tastes good too. In no time at all you will once again be able to enjoy ketchup again."

  1. If you're very sensitive to corn you might need to avoid tomato paste that contains citric acid made from corn. There is organic corn, so the paste being organic is no guarantee.
  2. I think the original poster forgot to include water as an ingredient. I put 2 cups in, added more spices. Some white pepper, more garlic and onion powder, and added salt. I also used a little more sweetener...I chose honey and maple syrup. It's perfect now!
  3. I have been using this to make our own ketchup since June of 2011 because of the corn syrup and white vinegar in store-bought ketchup. While I can't say I like it quite as much as store-bought, it works with our diet. The flavor is okay, but the texture is quite a bit thicker, which some people might enjoy. I will continue to use this recipe. I have found however that the recipe makes closer to 2 cups ketchup and not the 4 cups as stated.
  4. Thank you for sharing this. I love it and we use it in place of our ketchup all the time.
  5. YUM! Our youngest is corn sensitive and I am so glad I found this! Now he can have ketchup like everyone else! My favorite part? It was SO EASY!


I run an allergy friendly kitchen for my three boys, the oldest of which has allergies to wheat and corn. I believe in healthy, organic cooking whenever possible. I try to create recipes that are familiar favorites but with allergy friendly ingredients. I stay away from artificial flavors, colors, and preservatives as well.
