Free Printable: Low Carb & Keto Food List
Get It NowCreating the perfect keto ketchup recipe was no different than developing sugar free BBQ sauce and keto pizza sauce. After much trial and error, I perfected a sugar free ketchup that tastes just like the real deal and stays low carb enough for a keto diet. You can cross this one off your list of favorite foods you miss!
The official start of summer may be a few weeks away, but grilling season is definitely here — and, you’re going to need this low carb sugar free ketchup recipe for all your cookouts this summer. Your guests (or your kids) won’t guess it has no added sugar and is keto friendly. You might even forget it yourself. 😉
Is Ketchup Keto?
Traditional store bought ketchup is not keto. It’s made with added sugar, or even worse, high fructose corn syrup. There are some sugar free ketchup brands, but most of them use artificial sweeteners like sucralose.
Fortunately, there is still a way to enjoy ketchup on a low carb diet and avoid sugar. Just use my homemade sugar free ketchup recipe instead!
The key to making low carb ketchup or keto ketchup is really just the sweetener. Instead of sugar, or syrup, I used Besti Powdered Monk Fruit Allulose Blend, which dissolves easily and ensures that the ketchup is smooth, not grainy.
In fact, it tastes so much like the real deal that I included it in my Easy Keto Carboholics’ Cookbook, along with several other delectable sauces and spreads.
Ingredients & Substitutions
This section explains how to choose the best ingredients for the best sugar free ketchup, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.
- Tomato Paste – Adds classic tomato ketchup flavor. If you don’t have any on hand, you can simmer tomato sauce until it reduces to a paste consistency.
- Water
- Besti Powdered Monk Fruit Allulose Blend – Some sugar substitutes work better than others, and this one is my top recommendation. Other sweeteners can crystallize or not fully dissolve, leading to a gritty texture. You can use a concentrated liquid sweetener if you prefer, such as liquid monk fruit extract or stevia, but keep in mind that these can create an aftertaste and you’ll need to use much less.
- White Vinegar – Use apple cider vinegar to make this homemade ketchup paleo friendly.
- Spices – To make this tomato ketchup taste similar to Heinz, you will need sea salt, onion powder, garlic powder, paprika, ground cloves, and mustard powder.
How To Make Sugar Free Ketchup
This section shows how to make keto ketchup, with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.
- Combine. Whisk all ingredients in a small saucepan, until smooth.
- Simmer. Gently bubble over low heat, with a cover, until the sugar free ketchup thickens (reduces) to your desired consistency. Stir occasionally while simmering. Taste, and adjust salt and sweetener if needed.
- Blend. For the best keto ketchup that’s silky smooth, transfer the mixture to a high-powdered blender (this one is my favorite) and puree. This step is not required, but I highly recommend it for the smoothest texture that is most similar to the ketchup you’re probably used to.
TIP: Simmering time will vary.
The time can vary widely depending on the size of your pan and your stove temperature. Larger pans will need less time.
Storage Instructions
- Store: Keep keto ketchup in an airtight container in the fridge for 1-2 weeks. If separation occurs, give it a stir and it will return to normal.
- Freeze: Pour into an airtight container or freezer bag, then store in the freezer for up to 3 months.
Ways To Use Keto Ketchup
Fries — which are not low carb — are probably the food that comes to mind when you think of ketchup. But don’t worry, there are alternatives and other tasty ways to enjoy keto ketchup in your favorite meals:
- Burgers – Use it to top your burgers sandwiched between low carb hamburger buns. Add some homemade mayo on them while you’re at it! If you’re making burgers for a cookout, serve your burgers with grilled cabbage steaks or a creamy cauliflower potato salad.
- Chicken – Dip keto chicken nuggets (pictured above) or crispy keto chicken tenders into sugar free ketchup. They just aren’t the same without the right condiment!
- Fries – Try my favorite keto french fries or even low carb cauliflower tots. You can also serve it with garlic parmesan fries for family members who aren’t keto.
- Meatloaf – Slather a layer on a keto meatloaf or a savory bacon wrapped turkey meatloaf.

0This was delicious! I made it to use on the Wholesome Yum keto meatloaf, which was also wonderful. I’m very glad I went ahead and made a double batch tonight for the first try of this recipe, because we all loved it! Both recipes will be regulars in our house!
Steve Volker
0Will Truvia work? I use it in all my recipes to date.
Maya | Wholesome Yum
0Hi Steve, I don’t recommend Truvia, as it’s over 99% erythritol, which has issues as explained in the post above. The ketchup can turn out gritty initially, and if it doesn’t, it will often crystallize when storing.
Pam
0Could I use Canning salt and Swerve or Splenda in place of Allulose?
Maya | Wholesome Yum
0Hi Pam, Swerve will not work well, as the ketchup will be gritty. Splenda might work, but I don’t recommend sucralose for health reasons.
Janice
0I can say that this keto, sugar-free ketchup is a lifesaver. I am always looking for alternative condiments for my meals, and luckily I came across your recipe! I prefer this homemade ketchup to store-bought ones! I would definitely save this recipe for future use!
Joshua Weberg
0I was super happy to find this recipe. I have grown tired of the ketchups at the store that are loaded full of sugars. This ketchup was tasty and made for the perfect replacement ketchup on my burgers.
Jane
0I have tried both Heinz and Keto Sugar-Free Ketchup, and I definitely prefer Keto. It has a much stronger, more savory flavor than Heinz.
