Jump to RecipeThis Slow Cooker Spaghetti Sauce is one of my favorite family recipes. Growing up, my mom used to make it for special occasions and I just loved it! And I didn’t know this at the time but she would often double the recipe and freeze half of it for later, so we could have a special meal whenever. I follow in her footsteps and often make a double batch and freeze it for later as well.
Slow Cooker Spaghetti Sauce simmers away all day and develops an amazingly rich flavor, so by the time you are ready to eat, the flavor is bold and delicious.

How to Make Slow Cooker Spaghetti Sauce
This sauce is not hard to make, but tastes really amazing. And it is so wonderful to have amazing smells coming from the kitchen as this simmers away all day. You’ll be so ready to eat come dinner time.
To make this sauce, you’ll start by cooking the Italian sausage over the stove. Cook until it is browned all the way through, breaking it up as it cooks. I like to use this meat chopper to break up ground meats because it’s way faster and easier than using a wooden spoon or another utensil. Soak up any excess grease with a paper towel. I like to cover whatever utensil I’m using with a paper towel and soak up the grease that way.
Grease your slow cooker or use a liner, and add all of the ingredients, including the cooked sausage. Stir everything up really well and cover. Cook on HIGH for 5 hours or LOW for 7-8 hours. When ready to serve, remove the bay leaves and serve over cooked pasta.
Can I Freeze this Recipe?
Absolutely! I like to make a double batch, and freeze half of it in a big container or plastic bag after it is cooked. Then, I just heat it up and serve it whenever I want fresh pasta sauce.
