Print Recipe


  • 4 pounds tomatoes
  • 2 ½ teaspoons Truvia or 2 Tablespoons (3 packets) low carb sweetener
  • 1 teaspoon dried oregano
  • 1 teaspoon basil
  • ½ teaspoon garlic powder


  • Skin tomatoes by first gently cutting an “X” at the base and then placing in boiling water for 30-60 seconds.
  • After skin has been removed, cut in quarters and place in microwave safe bowl.
  • Add sweetener and seasonings.
  • Cook uncovered in microwave on MED HIGH to HIGH (depending on wattage) for about 15-20 minutes.
  • Pour out excess liquid and cook for another 5-10 minutes.
  • Place tomato mixture into blender or food processor and puree.
  • Can be used immediately or canned for later use.


To save time, peeled canned tomatoes can be used instead of fresh. Tomatoes can also be cooked on the stove rather than the microwave until softened, about 15 to 20 minutes.
