Slow Cooker Tomato Sauce

There’s nothing like slow cooked pasta sauce that’s been simmering on the stove all day. It’s even better when you can make it in a slow cooker. Loaded with spicy Italian sausage, fire roasted and crushed tomatoes. This sauce is simmered low and slow for 8 hours! The sauce gets super thick, rich and loaded with flavor.

Amazing Slow Cooker Tomato Sauce

This slow cooker tomato sauce is rich, hearty and comforting. The perfect meal for busy weeknights or Sunday dinner.

This recipe makes enough to serve 6-8 people and always leaves tons of leftovers.

Super Easy Slow Cooker Tomato Sauce


This sauce is super easy to throw together and only takes 5 minutes of prep time. I like to brown my sausage in a skillet before adding it to the slow cooker for extra flavor. I know it’s an extra step but it is totally worth it! Throw everything in the slow cooker in the morning and come home to an awesome home cooked meal.

Serve this Slow Cooker Tomato Sauce over spaghetti or zucchini noodles (my favorite!)

  • YUM! This looks so good!! What a great recipe! Perf for the fall!! SO tasty! …I love nourishing dishes like this! SO lovely 🙂

  • I am all about the slow cooker year round, but especially this time of year! AND especially if it involves making a delicious, hearty tomato sauce!! Love your addition of Italian sausage and that you used my favorite fire roasted tomatoes! This looks absolutely PERFECT! Pinned! Cheers, girlie!

  • This tomato sauce looks so delicious, Kelley! I love that you can make it ahead in a slow cooker…so convenient! And I agree, I think browning the meat in the pan before always adds more flavor in the end, so that extra step is totally worth it. Can’t wait to give this a try! Thank you! 🙂

  • This tomato sauce looks so fantastic! I love that you can cook it in the slow cooker too, things like that are so much better when they simmer for a long time!

  • Anything home made is great as you know what in it and also I love slow cooker recipe. Slow cooker is the best help for busy people like me. Thank you for sharing the recipe.

    • Hi Tom,

      No not all. I was worried about the same thing when I first made this and was pleasantly surprised at how thick the sauce became. The tomato paste and long cooking time keeps the sauce nice and thick. I hope you enjoy if you choose to make it!

      Thanks,

      Kelley

    This is very similar to the sauce that I make. I add neck bones for extra flavoring and of course remove them before serving.

    • Hi Kamika,

      No this recipe cannot be canned. I am pretty sure lemon juice or vinegar needs to be added to be able to can the sauce.

      Thanks!

    Do you chop the sausage, or just put that browned links in the cooker? I am guessing they crumble into pieces after cooking in the sauce that long? Also, can the sausage be omitted?

    • Hi Hap!

      Yes the sausage can be omitted from the sauce. I use ground sausage and stir it around so no need to cut it up.

      Thanks!

    Made this yesterday. I sautéed an onion and mushrooms and added them about 2 hours in. Sauce was delicious!

  • Annamaria Christensen

    Instead of sausage can I brown meatballs and add them?

    I’m cooking this recipe as I type. After 40 years of cooktop sauce I thought it was time to modernise. One thing I had to adjust was the lack of garlic. I just can’t make red sauce without it. One large clove, minced and added to browning sausage about a minute before it was ready for the pot. Also, since I’m retired, I’m going to cook it on high and check it at 4 hours.

    Made this with hot Italian sausage links and ground that and the fire roasted tomatoes in a blender bc we don’t like chunks of either. Turns out it’s an amazing base recipe and you can add other spices, etc to taste. I cook minced garlic in a skillet with garlic before blending. I also do about a tsp each of garlic and onion powder. I find that doubling the other spices and adding some chicken bouillon and sugar (depending on bitterness of the crushed tomatoes) results in the best sauce. Thanks for the recipe!
