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.

  • Cover and cook for 2 hours on High or 4 hours on Low.

  • 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.

I was very skeptical about the "no peel" part, having tried not peeling my tomatoes in the past and still had to spend an hour or so picking out the cooked peel. But when you puree the sauce with the immersion blender - they disappear! 6 pounds of tomatoes filled my slow cooker before I cut and seeded them. I added a bunch of fresh basil too . I only gave this a 4 instead of a 5 as I reduced my sauce on my stove as the slow cooker was taking too long. But the finished sauce is delicious. Read More
