Slow Cooker Pizza Sauce

Sharing is caring!

Slow cooker pizza sauce:

Within the past year or so, I’ve been making recipes related to pizza. Calzones, pizza quesadillas… I’ve even started making my own pizza crust in my bread machine! For the longest time, I’ve just bought jars of pizza sauce. It’s convenient and tastes good, but I knew I could make my own somehow! After trying this, I’m never buying jarred pizza sauce again. The best part is that it makes so much, I can freeze the rest in individual sized bags to use in future recipes!

What you need:

Tomato paste
Tomato sauce
Parmesan cheese
Italian seasoning
Vegetable oil
Garlic powder
Salt and pepper

Slow cooker pizza sauce:

Add all ingredients except Parmesan cheese in the slow cooker and give it a good stir. Set to LOW and cook for 4 hours, making sure to stir every 30 minutes to prevent the sauce from sticking.

After 4 hours, add the cheese and stir again, and then serve however you like!

We used ours as the dipping sauce for pizza quesadillas.

After the sauce has cooled, store the leftovers in quart-sized freezer bags. How many just depends on how much sauce you like to use for each recipe. We were able to get 3!

If you lay the bags flat like this in the freezer, they’ll stack easily once frozen to save room in your freezer!

So because I’m a nerd and love seeing how much money I’m saving, here’s a breakdown of the cost of this versus a jar of pizza sauce:

1 jar of Ragu pizza sauce, 12 ounces: $1.29

This entire recipe, which makes about 45 ounces, or almost 4 jars: $2.20

  • Price per “jar”: $.55!

That’s a pretty big savings! Plus you control the ingredients that are being put in and can freeze the leftovers, saving even more money!
