Store-bought pasta sauce just can't compare to homemade marinara--and the slow cooker makes marinara from scratch much easier. This fresh tomato recipe was developed to preserve the summer bounty from your garden or farmers' market; it freezes well for up to 6 months so you can pull out pasta or pizza sauce anytime. Keeping the skins on makes it even easier, plus they contain pectin, which helps thicken the sauce. Source: EatingWell Magazine, September 2020

  • Cut tomatoes in half crosswise. Gently squeeze out the seeds and discard (don't worry if you don't get them all). Mix onion, oil, tomato paste, garlic, oregano, vinegar, sugar and 1 teaspoon salt in a 6-quart or larger slow cooker. Place the tomatoes on top.

  • Puree with an immersion blender or in a regular blender in batches until chunky. (Use caution when pureeing hot liquids.) Placing the lid askew, cook until thickened, about 3 hours more on High or 6 hours more on Low.

  • Season with the remaining 1/2 teaspoon salt and pepper (or crushed red pepper) to taste. Puree further, if desired. Serve hot or let cool completely before refrigerating for up to 5 days or freezing for up to 6 months.
