This Homemade Ketchup Recipe is a delicious and easy recipe to enjoy healthy tomato sauce with your fresh vegetables or on your tortillas.
Your typical ketchup, also known as Tomato Sauce in the Commonwealth, is not that healthy. Regular ketchup has about 20 grams of sugar per 100 grams! And no, carbs in ketchup do not solely come from tomatoes. Store-bought ketchup is so high in carbs because it has added sugar.
Ingredients and Substitutions
Tomato is a healthy vegetable, so let’s see below how we can turn this vegetable into homemade ketchup!
- Tomato Puree or fresh tomatoes.
- Tomato Paste made with only tomatoes.
- Onions for the taste. Yes, onions are also a low-carb vegetable. Not the lowest, but since we’re not using too many of them, it’s fine!
- Crystal Sweetener – You can use regular honey, sugar, coconut sugar, or erythritol to replace the sugar.
- Apple Cider Vinegar to add the typical bitter ketchup taste.
- Garlic – garlic powder or fresh crushed garlic.
- Ground Paprika – Or smoked paprika.
- Oregano – Or Italian herbs.
- Olive Oil – I use extra-virgin olive oil.
You can also add a touch of honey in this recipe. I would recommend using 4 tablespoons of honey instead of the 2 tablespoons of sugar and then adjusting to taste.
How To Make Healthy Ketchup
You only need a few basic ingredients to make perfect, healthy ketchup.
Making the recipe is very easy. It only takes a few steps!
- Chop your onions and the garlic cloves into small bits.
- Fry the onions in a saucepan with olive oil, and add the garlic and paprika.
- Once the onions are coated in paprika, add your tomato paste. Make sure it does not contain any added sugar!
- Let it simmer for a couple of minutes, and then add the tomato puree, also known as tomato passata. For a sweet taste, add any crystal sweetener you like, such as sugar, coconut sugar, honey or any sugar-free sweetener like erythritol. Let it simmer for a few more minutes over low heat.
- Once your sauce has thickened, use an immersion blender to turn it into smooth ketchup. The color of the ketchup is slightly lighter than the store-bought version, but the taste is very similar. This is a very simple ketchup recipe that makes about 10 ounces of ketchup (300g).
Storage Instructions
This homemade ketchup dip can be stored safely in the fridge for one week. Store it in an airtight container to let it keep its taste and texture.

Can you please let me know what brand of paste and purée you buy here in New Zealand
Ceres Organic is my favorite
What the heck are nasties!!!😃
Nasties refer to all the additive present in store-bought ketchup like food coloring, preservatives, sugar and more.
I have type 2 diabetes, this sugar-free ketchup will make a difference in my blood sugar testing, Thank you.
I am glad you found my blog, all my recipes are diabetes friendly. Enjoy and take care, XOXO Carine
Step # 5 – what is natvia? It is not in the ingredient list?
Sorry I updated the recipe, Natvia is the brand name of the sugar free crystal sweetener in New Zealand (where I live!). It is basically erythritol stevia blend known as Swerve in US. Enoy the sauce, XOXO Carine
Thanks so much again Carine!! 🙂 Looks amazing! Can’t wait to try! x
My pleasure! Enjoy, XOXO Carine
I don’t know what brown onions are, so used 1 small yellow onion. For sweetener I used 1 1/2 TBSP xylitol. Love this recipe and how easy it is. My third attempt at finding a homemade ketchup recipe that was edible. This is definately a keeper. Thank you.
Brown onions are small onion slightly less strong than yellow onion. You can use any onion you like for this recipe. I am so glad you enjoy that ketchup. Have a great time trying my recipes and thank you SO much for the beautiful comment. XOXO Carine.
Sounds like a good sugar free recipe using stevia! I’ll be trying it very soon, as I have been winging it with my own recipes for a few months. THank you.
It is a nice simple ketchup recipe that me and my kids enjoy. I hope you will love it too. Thanks for reading the blog and trying my recipes. XOXO Carine.
How long can you store this ketchup in the fridge before it spoils?
Hello! I store mine for up to 3-4 weeks in the fridge in a glass mason jar. Enjoy the recipe ! XOXO Carine.
Could I make a larger batch and freeze in portions? Thank you
I never freeze my ketchup but I am sure it will work well. It is basically a tomato sauce ! Enjoy the sugar free recipes on the blog. XOXO Carine.
What is the carb count for this.
Hi,
A portion of ketchup contains 1.9 net carb. This recipe serves 20 portions. The full nutrition panel is available after the recipe card. Enjoy the recipe. xoxo Carine.
Hi, I’m in the Uk and not sure what the difference is between tomato puree and tomato paste we tend to call tomato puree (the concentrated kind usually bought in a tube) both puree and paste. Could passata be similar to one of them? I really want to make this but don’t want to add something I shouldn’t! 🙂
Hi Polly, The tomato puree in NZ is the same as passata. The tomato paste is a thick concentrated tomato mixture that you can buy in tube or small pot. A mix of passata and tomato puree in tube will make the recipe perfect! Let me know how it goes! My family loves this clean food ketchup recipe ! Thanks for reading the blog and testing my recipe ! xoxo Carine.
Great thank you! Can’t wait to try it xx
Hi, what should my proportions be if I want to use fresh tomatoes?
Hi Neha, I would love to give you a perfect answer but as I did not use fresh tomatoes I have got no idea of how many tomatoes you need to make the tomato puree. I always use organic canned tomato puree and tomato paste. It is super fast and no nasties added. Enjoy the recipe ! Carine.
Omg this is soooo yummy. So glad i came across this ?
Hi Claire! I am glad you love this sugar free ketchup recipe. This is such a great way to enjoy a guilt free tomato sauce right? I hope you find even more healthy recipes on the blog. Carine.
I notice that in your sugar free ketchup, the recipe says oregano, but in your photos you have rosemary – can you use either according to taste or is one better than the other? Looking forward to trying this!
Hi Tosh, Good spotting! You are right I love adding a bit of rosemary in my ketchup recipe sometimes. The recipe I shared is the one I do regularly but I love to alter this recipe each time now by adding different spices. Lately I added a bit of smoked paprika to make a smoked ketchup, it taste almost like BBQ sauce and I love it. I recommend you to follow the basic recipe first and then, be creative and add some of your favorite herbs and spices to make it your own fav ketchup! Enjoy. Carine.
Just finished making a batch this was amazing Love Love Love the taste. I did put it in my blender for a few seconds to thin it out a little. Thank you for sharing
Hi Debbie, I am so glad you love it ! Good idea to blend the ketchup to make it smoother 🙂 I also do my own BBQ sauce now it is so much healthier when homemade! See you soon on the blog. Carine.
Hi. I will have to try this after we run out of the ketchup that we have. Thank you for sharing this with us.
Hi! My pleasure, my family love this simple recipe so easy, healthy and cheap to make. Enjoy 🙂 Carine.
