Homemade Ketchup

Updated 20-Sep-2023

Ketchup is a bit expensive and full of not-so-nice ingredients (or super expensive and organic). We make ours in about 10 minutes using tomato paste, water, salt, sugar, and vinegar. One can always add more ingredients (garlic, onion, etc.), but it is not necessary.


  • One small can tomato paste
  • 1/2 cup water
  • 1 TBSP sugar
  • 4 TBSP vinegar
  • 1/2 tsp salt


  • Simmer ingredients on the stove top, stirring until thoroughly mixed.
  • Let cool and store in a jar in the fridge

Substitutions and Additions

  • Lemon juice may be substituted for vinegar (2 times the lemon juice replacement ratio)
  • pepper, or cayenne pepper may be added
  • onion powder, celery salt, and / or garlic powder may be added
  • Maple syrup, or brown sugar may be substituted for sugar
