No Sugar Sauce

Sugar Free Ketchup | Sugar Free Tomato Sauce Recipe

Aren’t we all tired of buying overpriced sugar free & keto ketchup or tomato sauce at our local stores? Many brands charge so much just for removing sugar while you could have homemade ketchup for under $3 for 12 ounces.

It couldn’t be any easier to make a homemade ketchup recipe as it is all about balancing the salty, sour, and sweet flavors and you’re done. The flavor tastes better than normal store-bought ketchup without all that corn syrup with high fructose.

  • Shrimp cocktail – mix ketchup with Worcestershire, lemon, and Cajun seasoning to make a Bloody Mary-inspired cocktail sauce for shrimp.  
  • Homemade BBQ sauce – A lot of homemade BBQ sauce recipes start with ketchup as the base. It only takes 30 minutes to make it.
