I love anything cooked in my Instant Pot or a crock pot slow cooker.  I love the appeal of having my families dinner made up in a snap or while I am working all day!  This Crockpot Spaghetti Sauce is my favorite slow cooker recipe because it has so much flavor.

I love the Rao’s Marinara sauce that you can find in most grocery stores…but man is it expensive!  I love that it is delicious and it is the lowest in carbs I have ever seen.

I found the recipe for the Rao’s Marinara on the NY Times website and I adapted it to make in the slow cooker!

Now I am not sure how the jarred Rao’s sauce gets their carb count so low but I did my best on this one.


I say yes.  If you don’t brown your ground beef (or ground turkey) before you add your sauce to the slow cooker, you will have beef that doesn’t have as good of flavor, and you will have greasy spaghetti sauce.  Yuck!

For this crockpot spaghetti sauce, I heat the olive oil in a heavy bottom pan and then I sauté the salt pork to render out the fat.  I had never heard of salt pork before this recipe, but I bought it anyway.  I cut what I needed from the package and then froze the rest.  Salt pork is very similar to bacon, just much more salty.

After I rendered all of the fat, I removed the salt pork from the pan and I added in the onions and the garlic and sautéed them until soft.  Then I poured all of that yummy stuff into the slow cooker, as well as the crushed tomatoes.

My next step was to brown the meat in the same heavy bottom pan until it is cooked all of the way through.  I then added that to the slow cooker as well.

Now I just stirred everything together and set the crockpot on low for 8 hours.  The best spaghetti sauce is one that simmers all day, and the crockpot does just that!

Right before you are ready to serve the spaghetti sauce, taste for seasoning and add salt to taste.  I also added 6 torn basil leaves.

I love to serve my crockpot spaghetti sauce with zucchini noodles!

  • 2 Cloves of garlic, minced
  • 2 28 ounce Cans crushed tomatoes
  • 6 Leaves Fresh basil

  • In the same heavy pan, cook the ground meat until cooked through.  Add the meat to the slow cooker with a slotted spoon, leaving the fat in the pan.
  • Cook in the slow cooker on low for 8 hours.  When ready to serve, add in your torn basil and oregano and season to taste.  


  • You can use any ground meat you want in this crockpot spaghetti sauce...even sausage.
  • If you want to make this into a freezer meal: follow the steps above, but instead of putting the ingredients into a slow cooker, let them cool and put them into a freezer safe container.  When you are ready to cook the sauce, pull the container out of the freezer the night before, then cook in the slow cooker the next day.
  • If you want to cook this in the heavy pan instead of the slow cooker, Remove the onion and oil mixture to a bowl before you cook the hamburger meat.  Then when your hamburger meat is cooked, remove the fat, add the onion and oil mixture back to the pan, followed by the crushed tomatoes, then let it simmer, covered, for 1 hour.

    What’s the carb count on the sauce? You mentioned you tried to get it low but I don’t see the counts listed anywhere.

      I got 8 carbs per serving, but can depend on the labels on your tomatoes.
