Equipment

Ingredients

  • 5 lbs Roma tomatoes
  • 1 Large yellow onion chopped
  • ¼ cup Olive oil
  • 5 Garlic cloves Pressed or minced
  • Salt and pepper
  • ¼ cup Fresh basil
  • 1 tablespoon Sugar substitute
  • 2 teaspoon Dried oregano
  • Optional: Crushed chilies, fresh parsley, etc

Instructions

  • Preheat oven to 400F.
  • Cut tomatoes into quarters, removing the stem pieces. Place in a large roasting pan - ideally nonstick.
  • Add onion, olive oil, garlic, and a little bit of salt and pepper, tossing gently to coat.
  • Roast for 60-80 minutes, stirring every 20 minutes or so.
  • Allow to cool enough to handle.
  • In batches, puree the contents of the pan, transferring to a pot as you are happy with the consistency of each blitzed batch.
  • In one of the batches, add basil, sugar subsitute, and oregano when processing.
  • Stir the entire thing together, seasoning with salt and pepper - as well as any optional herbs and spices - to taste.
  • If you’d like it thicker, simmer it until it reaches desired consistency.
