This Low FODMAP Ketchup Recipe is onion-free and garlic-free. Made simply of tomato puree, vinegar, sugar and salt.

Tomatoes and I have a complicated relationship. While they are not high in FODMAPs, I still have issues tolerating them. That’s why I don’t have too many recipes featuring tomatoes on my blog. It took a while, but I finally figured out that tomato paste was the main culprit. I would end up with pain for several days after eating it.

I seem to do fine with a little fresh tomato and some cooked tomato. However, tomato paste is a highly concentrated form of tomatoes. Since I have a slight issue with tomatoes, the paste can turn it into a huge issue. This is why I decided to make my own ketchup with tomato sauce instead of tomato paste.

Finding Tomato Sauce or Puree

Now, finding tomato sauce without any onion or garlic added is another story. I was able to find two brands in the natural foods store and co-op that I shop at that fit the bill. Pomi Strained Tomatoes, Pomi Tomato Sauce, and Full Circle Organic Tomato Puree (As an Amazon Associate, I earn from qualifying purchases). All are unsalted, which I love, because then I can adjust the salt to my own taste. Once you find the tomato sauce/puree, the rest is pretty easy.

This Low FODMAP Ketchup Recipe is a little thinner than regular ketchup, but has tons of flavor. Serve on hamburgers or with french fries. I’m hoping to post my own meatloaf recipe here soon, and this ketchup is fabulous served with it! NOTE: I ended up including this meatloaf recipe in my cookbook!
