Slow Cooker Tomato Sauce

I would’ve liked to have made this slow cooker tomato sauce using tomatoes from our garden. For some reason, our tomatoes just didn’t produce this year. Usually I have to worry about the raccoons stealing them but not this time. They just didn’t come out. So, Plan B, I picked up a big batch of ripe tomatoes at the grocery store. The end result came out very, very flavorful. Quite honestly, I had my sights set on using this sauce to make pizza sauce, but it’s so good by itself you could easily serve it as-is as tomato soup.
slow-cooker-tomato-sauceI used Roma tomatoes because I like how they taste. You can substitute any good tomato, just make sure they’re good and ripe. Do not use those hard-as-cardboard tomatoes you often find at your grocery store. If you’re lucky enough to be near a farmer’s market, it’s well worth the trip. When tomatoes are at peak you’ll want to make several batches of this slow cooker tomato sauce and freeze it for later.
