Slow Cooker Marinara

For a simple and flavorful sauce, it doesn’t get any better than this Slow Cooker Marinara. We start by sautéing onions and garlic and then layer in the seasonings. Then we add crushed tomatoes, tomato paste, and balsamic vinegar and let it all simmer in the slow cooker. The result is a tomato sauce that has a surprising complexity of flavor.
