  • 15 cloves garlic
  • 8 pounds ripe tomatoes (any variety), cored and quartered
  • 10 medium onions, quartered

  • ½ cup olive oil
  • ½ teaspoon salt
  • freshly ground black pepper, to taste
  • 3-4 tablespoons sugar, optional

Tips & Notes

This roasted tomato sauce can be refrigerated for up to 3 days or frozen for several months.



  1. Preheat oven to 450 degrees. Peel the garlic and chop 5 of the cloves, leaving remaining 10 cloves whole.

  2. In a large roasting pan, gently toss together the tomatoes, whole and chopped garlic, onions, herbs, oil, salt and pepper.

  3. Roast for 25 minutes. Gently stir the vegetables.

  4. Roast for another 25 minutes and gently toss.

  5. Roast for another 45 minutes or until the tomatoes are softened and somewhat broken down into a sauce, with a golden brown crust on top.

  6. Remove from the oven and taste for seasoning. Add a few tablespoons of sugar if it tastes bitter.

  7. If you like a smoother consistency, pour the finished sauce into a blender or food processor and blend until it is the texture you like. Pour the sauce into freezer bags if not using immediately. (It can be frozen for up to 6 months.)

  8. Use over pasta or in any recipe that calls for tomato sauce.
