Ingredients

  • 2 tablespoon olive oil
  • 1 cup chopped onion
  • 1 tablespoon minced garlic
  • 2 28 oz cans diced tomato (I like to buy the kind with onion and garlic in it for extra flavor, but this is optional)
  • 1 28 oz can crushed tomato
  • 1 14 oz can whole peeled tomato
  • 1 6 oz can tomato paste
  • 1 teaspoon oregano
  • 1 tablespoon dried basil
  • 2-3 bay leaves
  • 1.5 teaspoon kosher salt
  • ½ teaspoon fresh ground pepper
  • 2-3 pieces Parmesan rind This is optional, but if you aren't vegan or dairy free, I think it really adds to the flavor.

Instructions

  • Add first 3 ingredients into slow cooker and let them get started cooking on high while opening the cans and gathering all remaining ingredients together
  • add remaining ingredients and stir.
  • add Parmesan rinds if using (optional) and stir to incorporate
  • Turn slow cooker down to low and cook for 8 - 12 hours
  • remove cheese rinds and use immersion blender if you prefer a smoother consistency.
