Free Printable: Low Carb & Keto Food List
Get It NowGrilling season has officially kicked off, and I’ve got the perfect companion for all your cookout favorites: My sugar free ketchup! I was never happy with the ingredients in the store-bought stuff, so — many, many taste tests later — this has been my go-to homemade ketchup recipe for years. Guests (and even kids) can’t tell it has no added sugar. And it’s keto, too! Make it with me, and get ready to elevate your burgers, hot dogs, and everything in between.
Why You Need My Sugar Free Ketchup

- Tastes like the real thing – This isn’t just the best sugar free ketchup I’ve ever had… honestly, it’s the best ketchup I’ve had, period. It’s sweet and tangy, it’s smooth and thick, it’s even got umami notes. You’re going to love it.
- Quick and easy to make – Just mix all the ingredients and let them simmer away. It’s so simple. And it lasts beautifully for weeks in my fridge.
- Naturally sweetened, keto, gluten-free, and diabetic friendly – Most store-bought ketchups are packed with added sugars, corn syrup, or artificial sweeteners, like sucralose. Not mine! With just 2 grams of net carbs per serving, this is a true keto ketchup. (In fact, you’ll find it in my Easy Keto Carboholics’ Cookbook with some of my other fave sauces and spreads.) But even if that’s not your jam, this healthy ketchup is also just better for you than those processed ones!


Ingredients & Substitutions
Here I explain the best ingredients for sugar free ketchup, what each one does in my recipe, and substitution options. For measurements, see the recipe card.
- Tomato Paste – This is the base and the main flavor. I prefer a can of tomato paste combined with a cup of water, rather than tomato sauce, because the flavor is more intense that way. But if all you’ve got is tomato sauce, use 2 cups of tomato sauce and 2/3 cup of water instead — and you’ll need to simmer for much longer to let it reduce.
- Besti Powdered Monk Fruit Allulose Blend – The key to making low carb ketchup or keto ketchup is really just the sweetener. This one dissolves effortlessly, and tastes and measures like sugar, so it’s the only one I like in my sugar free ketchup. Notes on other options:
- Powdered allulose also works great, but add 1 1/2 extra tablespoons.
- Most other sugar substitutes will crystallize, leaving a gritty or grainy texture. (This includes most brands labeled “monk fruit” or “stevia”, which are usually mainly erythritol or maltodextrin — check the ingredient list and you’ll notice it’s listed first.)
- Concentrated liquid sweeteners, like liquid monk fruit extract or stevia, would work, but these will leave an aftertaste and you’d need to use much less.
- White Vinegar – To make the ketchup tangy. Apple cider vinegar or white wine vinegar make a decent substitutes, they’re just a bit less neutral in flavor.
- Spices – You’ll need sea salt, onion powder, garlic powder, paprika, ground cloves, and mustard powder. I modeled these after Heinz, but had to improvise because they don’t publish the exact spices. Funny enough, some readers are telling me mine tastes better — so thank you! 😊

How To Make Sugar Free Ketchup
I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card.
- Combine the ingredients. Grab a small saucepan and whisk all your ingredients together, until smooth.
- Simmer the mixture. Let it gently bubble over low heat, covered, until it thickens up to just how you like it. Don’t forget to give it a stir now and then.


- Blend until smooth. For the smoothest, silkiest sugar free keto ketchup, pour it into a high-powered blender (I swear by this one!) and puree. This step is optional, but it makes all the difference if you’re after that classic ketchup texture.


My Recipe Tips
- Stir occasionally, but otherwise keep it covered. The sugar free ketchup can splatter as it simmers, especially as it gets thick, so a lid prevents a big mess.
- Simmering time can vary widely. It can depend on the size of your pan, the exact heat of your stove, and even your brand of tomato paste. Bigger pans will need less time.
- Cooked it too long? Just add more water to thin it out.
- Adjust to your taste. You can always tweak it at the end! If it’s too tart, add a bit more powdered Besti. If it’s too flat, a pinch more salt could do the trick. If it’s too salty, a splash of vinegar can perk it up.
Storage Options
- Store: Pour your keto ketchup into a mason jar or other airtight container (I like to use a squeezable bottle with a flip cap!), and stash it in the refrigerator for up to 2 weeks. If you notice any separation, just shake or stir it, and it’ll be good as new.
- Freeze: You can freeze the whole batch in zip lock bags, but I prefer a silicone ice cube tray, so I can pop out individual portions. (I do this for my sugar-free BBQ sauce as well.) Either way, this sugar free ketchup will keep in the freezer for up to 3-6 months.
- Canning: I haven’t tried it yet, but you should be able to can this in a water bath.

Serving Ideas
You probably already know the most common ways to use ketchup, but here are my healthier versions of the classics:
- Burgers – Slather this ketchup and homemade mayo on your hamburgers tucked between low carb hamburger buns, along with lettuce, tomatoes, and red onions. If you’re grilling for a cookout, my creamy cauliflower potato salad is the perfect pairing.
- Hot Dogs – Make hot dogs on my keto hot dog buns, or try my bacon wrapped hot dogs for something new.
- Chicken – Dip your keto chicken nuggets (pictured above) or crispy low carb chicken tenders into my sugar free ketchup. My kids love them.
- Fries – My fave low carb options are rutabaga fries, jicama fries, or cauliflower tots. If you’re reducing sugar but not strict on carbs, dunk garlic parmesan fries or air fryer french fries instead.
- Meatloaf – Whether it’s a classic meatloaf or my special keto meatloaf, don’t forget to top it with a generous layer of this sugar free ketchup. It adds that perfect tangy finish!

Sugar Free Ketchup

Gratitude Moment

Here’s me a couple years ago during a YouTube video shoot of making my low carb meatloaf, with this keto ketchup on top as a glaze.
Lately I’ve been thinking about how much I miss making those videos, something I thought I’d never say. As a pretty shy introvert, they were so hard! But they also stretched me to grow, and for that I’m grateful.
In case you missed it, I put a pause on YouTube when we moved to Florida. I needed time to get settled, get new equipment… oh, and figure out how to shoot those videos myself for the first time ever, instead of having help from my videographer friend.
It’s going to be a whole new learning experience, but I can’t wait! So if you want to be the first to know when I post my next recipe video, subscribe to my channel here.

0I used Rotel tomatoes instead of tomato paste, because we love spicy! I used Stevia for sweetener.
Delicious for meatloaf sauce!
Bryan
0Erythritol has zero nets carbs. Because erythritol is a sugar alcohol, the carbs aren’t able to be processed by the body.
jojobe
0Erythritol is not recommended to those of us with heart conditions or high blood pressure.
Tris
0Some people, such as myself, cannot handle the erythritol. Allulose is also 0 n net carbs. There are natural sugars in the tomato paste.
Sally
0The cloves killed it. I will make again but leave the cloves out then I think it will be my favorite ketchup recipe.
Tris Elftman
0Cloves are what makes ketchup taste like ketchup but I definitely understand having any aversions. I hope it worked out!
Susan
0I think the carbs might be miscalculated.According to carb manager 1/4 cup of Besti Powdered Erythritol is 36 total carbs. That ingredient alone would make it 3 total carbs per the 1 tablespoon serving. With the carbs in the spices, it adds 3.1 more total carbs. For a total of 39.1 total carbs or 3.3 per 1 tablespoon serving. Please advise.
Recipe tastes very good.
jojobe
0I used monk fruit sweetened honey and it added no sugar alcohol and no carbs. The flavor is sweeter than sugar so I was careful and there is no obvious sweetness just a balanced flavor.

0Hi Susan, Nutrition facts are provided as a courtesy. If you have questions about calculations or why you got a different result please see our nutrition policy.

0I loved this recipe! I’ve already written it down and put it in my family recipe box. I plan on mixing the dry ingredients to keep on hand so I can make a quick batch when needed. The ground cloves added a nice dimension to this recipe; it was the perfect amount.
Mi
0Love it. So glad I found this. I also made the meatloaf that went along with it. Loved it also.
Sharon
0Just wondering how long it keeps in the fridge, please 😀 If its not used straight away, what is the best way to store it?
Wholesome Yum D
0Hi Sharon, There is a whole section in the article on how to store the sugar free ketchup.
Heather Collins
0Love this recipe and your BBQ sauce is to die for. Can I freeze these? We don’t use a lot of either sauce but I hate wasting anything.
Wholesome Yum D
0Hi Heather, I have never tried to freeze this because I am not sure if it would be good after thawing due to the vinegar.
Haleigh
0Very excited to make this thanks!
Brian
0LOVE this ketchup. It’s all we use now… and my stepson even said he was “giving up H***z,” which used to be the only brand he’d eat. Just finished up a batch scaled up for a #10 can (6 lb 15 oz) of tomato paste. Made just over 6 quarts, 5 of which I put in a water bath for 15 minutes. I’m no expert, so don’t quote me on it, but as the pH was around 3.5, I figure it should be fine.
Nancy
0Love this recipe. I replaced erythritol with 4 dates (they cooked down and blended in perfectly). Plus, I added 1/8 tsp cayenne pepper to add a bit of a kick.
sam
0This is truly the best keto ketchup recipe, it far exceeds anything you can buy in the store. Thank you for sharing!
Beverly Brooks
0Can you make this salt free or there’s something else to substitute for salt?
Wholesome Yum M
0Hi Beverly, There are several salt-free products you can use in place of salt. Potassium chloride is commonly used as a salt substitute.
Nifrey Tero
0If using liquid monkfruit, what quantities do we use for this same recipe?
Wholesome Yum D
0Hi Nifrey, Sorry, I have not tested that. Let me know how it goes if you do.
Sharla
0So good! I made this the first tine when I was out of Primal Kitchen ketchup. Making it again today. Taste is great!
Yayra Gunu
0Tried this for the first time and it’s really YUM
Keto_Creed
0Thanks for the recipe. Where do I get the tomato paste from? Do I need to buy it or make it myself?
Stacey
0This ketchup is my go to, and we love it in our house. What is the shelf life for this recipe when refrigerated? Thanks!
Wholesome Yum M
0Hi Stacey, This recipe is good for a week+ in the fridge. Enjoy!
Wholesome Yum M
0If you are in the US, you can find tomato paste in any grocery store. It’s with the canned goods, but can be found in a tube as well. If you are located outside of the US, then you will want to look for a concentrated tomato product. It should have a thicker consistency than a tomato soup or tomato sauce products. I hope this helps to clarify what you are looking for!
Maureen
0I’m a little bit of a ketchup snob and this is bar none the BEST homemade ketchup I’ve ever made
Nancy Blanchard
0Love, love this ketchup…tastes amazing and I always make a double batch!
Thank you so much,
Nancy
Tonya Courchesne
0This ketchup is perfect. I prefer to any store bought brand which seem bitter. Thank you for creating this!
James
0I didn’t see any comments about making with stevia. What would the proper amount be? Thanks for posting this, can’t wait to try it.
Wholesome Yum M
0Hi James, You definitely can make this recipe using liquid stevia. Check this sweetener calculator here to figure out the correct amount.
