Homemade Roasted Tomato Sauce


  • 18-20 large Roma tomatoes, cut in half
  • 1/4 cup olive oil
  • 4 cloves of garlic, minced
  • 1 onion, diced
  • 1 tablespoon Italian seasoning
  • Handful of fresh basil leaves, chopped
  • 4 sprigs of fresh rosemary, stems removed
  • Salt and pepper to taste
  • About 1 1/2 cups of water
  • 1 tablespoon of sugar


  1. Line baking sheets with parchment paper. This makes for easy clean up. Set aside.
  2. Pre-heat oven to 300 degrees.
  3. In a large bowl mix olive oil, garlic, onion, sugar and Italian seasoning.
  4. Place cut tomatoes in the bowl and gently coat the tomatoes with olive oil mixture using a spoon or your hands. Place tomatoes cut side up on baking sheet and top with fresh herbs, salt, and pepper. Roast for approximately 2 hours.
  5. After 2 hours increase the heat of the oven to 400 degrees. Roast approximately for another 15 to 20 minutes.
  6. Remove roasted tomatoes from the oven and allow to cool for a few minutes. Place tomatoes in a food processor or blender and puree to desired consistency. Add water to thin out if you like a thinner sauce.
