Easy Slow Cooker Spaghetti Sauce–Don’t buy cans or jars spaghetti sauce at the grocery store…make it at home! Make it at home in your slow cooker. It’s super easy and tastes amazing after simmering all day long. Make a huge batch and freeze the leftovers for an easy dinner another night.
This is a meatless spaghetti sauce but if you want you can easily add in cooked ground beef or ground turkey or Italian sausage. I love all of the Italian flavors in this spaghetti sauce and I love how it tastes even better with more simmering. This is a recipe that you can literally leave on low in the slow cooker for hours and hours.
Here are some other recipes to go with your homemade spaghetti sauce:

I’ll do this in a small pot on the stove, right? Microwave died and not replacing it:
