Ingredients

  • 3 pounds Roma tomatoes
  • 1/3 cup olive oil
  • 1 teaspoon kosher salt
  • 1 teaspoon fresh ground pepper
  • 1/4 teaspoon sugar optional

Instructions

  • Preheat oven to 400°.
  • Wash tomatoes, remove stems and blemishes and discard. Cut tomatoes in half lengthwise. Place on a parchment paper lined rimmed sheet pan.
  • Drizzle with olive oil and season with salt, pepper and sugar.
  • Roast for 1 hour.
  • Remove from oven and cool slightly, 10 to 15 minutes.
  • Pour into a food processor, scraping the oil and juices from the pan.
  • Pulse tomatoes for about 15 - 20 seconds for a textured sauce and process on high for about 30 seconds for a smooth sauce. Scrape sides and bottom of food processor and continue to process if you still have large chunks of tomatoes.
  • Pour into an airtight container and refrigerate for up to 3 days or use immediately.
  • For freezing, pour into a vacuum sealer bag or zip top freezer bag and seal.
  • Freeze flat for easy storage and thawing.
  • To thaw frozen tomato sauce, place in refrigerator a day in advance or thaw in a shallow dish of hot water for about 15 minutes.

Notes

Sealed in a vacuum sealer bag, tomato sauce will last up to 1 year frozen. If using standard zip top freezer bags, tomato sauce will keep up to 3 months.
