Make a big batch of Marinara sauce right in the slow cooker. This Freezer Marinara Sauce is great for recipes later such as spaghetti, lasagna and more!
We love having this sauce on hand for pizza, simple pasta dishes or even my Slow Cooker Parmesan Chicken Pasta recipe.
I made a big pot of marinara sauce in my slow cooker, then I portioned out the sauce into freezer bags. The entire month I will have fresh-tasting sauce for our meals. Not only does it taste good, but I save money by not having to buy jars of sauce!
How much does it cost to make a big batch of marinara sauce?
- 3 cans crushed tomatoes: $1.13 x 3
- 2 cans diced tomatoes: $0.59 x 2
- garlic: $0.34
- onion: $0.37
- freezer bags: $2.99 (note, you can save money by using your own containers instead of bags, see recipe for details)
Total: $8.27 (I already had seasonings on hand)
I divided the sauce into 1.5 cup (for pizza topping) and 2 cup portions (for pasta and calzone topping). After I divided the sauce up, I will have enough sauce for 7 meals. If you plan on using the sauce the same week you make it, ladle the sauce into jars or Tupperware and place in fridge. The uses for this handy sauce are endless. I am dreaming about making a lasagna, or making homemade cheese sticks and using this sauce to dip them in.
