Ingredients

  • 56 ounces canned tomatoes (2 28-ounce cans of whole, crushed, or diced)
  • 1/2 cup butter
  • 6 cloves garlic smashed
  • 1 tsp salt or to taste
  • 1/2 tsp pepper

Instructions

  • Empty the two 28-ounce cans of tomatoes into an oven-safe shallow dish. I used a 13 x 11 pyrex dish for this dish. If the tomatoes are whole, crush them with your hands or a potato masher. 
  • Dot the top of the tomatoes with butter. Yes, butter! Butter adds unbelievable richness and flavor to this sauce. Add the garlic.
  • Bake at 425-F for about an hour, stirring once or twice during the cooking time.
  • Remove from the heat and using the back of a fork or a potato masher, mash up the remaining chunks of tomato and garlic. Season with salt and pepper, and use in your favorite dish.
