Low FODMAP Ketchup
A super simple and delicious homemade low FODMAP ketchup to provide the comfort of your favorite condiment. Only a few ingredients and you will be on your way to making the best ketchup you’ve ever tasted.

When I first started the low FODMAP diet it felt like all condiments went out the window, and I looove condiments! I was so pleasantly surprised when I made this ketchup and it was actually delicious! I am not joking when I say this is my favorite ketchup I have ever had.

Why we love this low FODMAP ketchup
The ingredients are so simple, I will likely keep making this even when I can choose any ketchup my heart and taste buds desire.
I really love a good tomato-y ketchup. Store bought ketchups can be full or high fructose corn syrup and additives. Those ketchups taste fake and they aren’t good for you! Here you use real ingredients, and you know what you are putting in your body. My favorite store bought ketchup is Trader Joes. This recipe reminds me of that taste.
We use garlic oil and onion oil to pack major flavor into this low FODMAP ketchup. See our garlic oil recipe here.
Save Money
Low FODMAP condiments and products are nice to have on hand. However, the cost can add up quickly. This low FODMAP ketchup recipe will save you money. The ingredients we use are cheap and you likely already have them on hand in your pantry.
I created this recipe when I randomly was thinking about how I missed ketchup. When I looked up recipes for homemade ketchup, there was typically a long list of spices or more steps then I wanted to take. I aimed to simplify it, and few simple ingredients later, I mixed up a seriously easy and delicious ketchup.

Tips For Make Low FODMAP Ketchup:
- Purchase delicious tomato paste that you know you’ll love. When you are eating low FODMAP, you want quality ingredients so you can still delight in what you are eating.
- If you use brown sugar, this will be a thick ketchup. Thin it out by using a little water to make it to the consistency you desire.
- Feel free to use maple syrup in place of brown sugar if you prefer that option.
- You can also substitute apple cider vinegar (ACV) for white vinegar. We found that ACV lends itself to a stronger, more acidic flavor, and that we preferred the white vinegar.
- Add extra spices like mustard powder, paprika, or black pepper if you’d like. This is a simple basic recipe, but you can make it your own!
- See how to make your own garlic oil and onion oil here. You can also use store bought garlic oil. Make sure it is truly low FODMAP before purchasing it.
