Ingredients
  

  • 5 pounds cored whole tomatoes, fresh or frozen
  • 3 tablespoons extra-virgin olive oil
  • 2 medium onions, chopped
  • 4 cloves garlic, minced
  • 3/4 teaspoon dried basil or 1 tablespoon chopped fresh basil
  • 3/4 teaspoon dried thyme or 1 tablespoon chopped fresh thyme
  • 3/4 teaspoon dried oregano or 1 tablespoon chopped fresh oregano
  • 1 ¾ teaspoons salt
  • ½ teaspoon freshly ground pepper
  • 1-2 teaspoons sugar (optional)

Instructions
 

  • If using fresh tomatoes, bring a large pot of water to a boil. Score a small X in the bottom of each tomato, then blanch in the boiling water for 30 seconds to 2 minutes until skins loosen. Transfer to an ice water bath, then peel. For frozen tomatoes, rub skins off under warm water and thaw as needed.
  • Dice the peeled tomatoes, reserving any juice to use in the sauce.
  • Heat olive oil in a Dutch oven over medium heat. Add onions and cook until softened and golden, about 4-6 minutes. Stir in garlic and cook for another minute until fragrant.
  • Add the tomatoes, their juice, herbs, salt, pepper, and sugar (if using) to the pot. Bring to a boil, then reduce heat to maintain a gentle simmer. Let it cook, stirring occasionally, for 1 to 1 1/2 hours until thickened to your desired consistency.
  • Taste and adjust salt, pepper, and sugar to match your preference. Serve immediately or store for later use.

Notes

Pro tip: If you’re missing any of these, substitutions such as canned tomatoes (for fresh) or dried herbs (instead of fresh) can work in a pinch, though the flavor will vary slightly.
