This zesty slow-cooker tomato sauce sauce is an easy classic. Set it and forget it! And the result is so flavorful, it will quickly become a family favorite. Enjoy pasta, meatballs, chicken parm, and more!

Ingredients
4 tablespoons olive oil
1 small yellow onion, peeled and finely sliced
3 cloves garlic, peeled and minced
3 pounds (about 20 medium) fresh plum tomatoes, cored, peeled, seeded, and pureed (enough to yield 4 cups)
1/4 cup minced fresh parsley, or 1 tablespoon dried
3 tablespoons minced fresh basil, or 1 teaspoon dried
1 tablespoon minced fresh oregano, or 1 teaspoon dried
salt and pepper, to taste

Instructions

  1. Turn the slow-cooker on high, let it heat for 5 minutes, and add olive oil, onion, and garlic. Stir and cover. (The pot won’t get hot enough to brown them.) Cook for 1 hour, or until onion is soft and wilted.
  2. Uncover and add tomatoes, parsley, basil, oregano, salt, and pepper.
  3. Reduce the heat to low, and stir.
  4. Cook with the cover off for approximately 4 hours. The sauce is done when it is thick and not watery.

Not all tomato varieties are high in acid. In order to make them shelf-stable and last longer, add about 2 tablespoons of lemon juice or 1/2 teaspoon of citric acid per quart. For pints, add 1 tablespoon of lemon juice or 1/4 teaspoon of citric acid. Freezing really is your only other safest option.

Can this be canned in a hot water bath instead of frozen to keep longer?

sounds so good. Can slow cooker sauce be frozen for later? Thanks for your reply.

Yes, Kathy. Absolutely.

Why couldn't you "can" it afterwards? Like a hot water bath to seal? Please let me know.
