This recipe for crock-pot tomato sauce is as simple and good as it gets!
Did you know you can make a delicious, homemade tomato sauce in your slow cooker? This recipe for crock-pot tomato sauce is easy to make and perfect for pizza, pasta, and all your tomato sauce needs.
In this recipe, I’ll be sharing a simple slow cooker method for that same rich and delicious sauce you get from the 4-hour stove-top recipe.
Homemade Tomato Sauce
All you have to do is place some washed tomatoes in the crock-pot (no peeling, seeding, or coring needed), add some seasonings and heat over low for approximately 8 hours. That’s it.
Depending on your slow cooker’s size, you can double or triple the batch and use the extra for all sorts of meals or store for future use.

I love helping parents create various incredible meals with real ingredients and simple methods, hence this crock-pot tomato sauce. One batch can be used in several ways and made with canned or fresh tomatoes.
While I often use canned tomatoes for this recipe, you can also use fresh tomatoes when they are in season, so nothing goes to waste.
In case you do, you might want to remove the skin and de-seed the tomatoes, which is shown in this easy canned salsa recipe.
How Long Does Tomato Sauce Last?
While we are talking about nothing going to waste, this sauce stays fresh for 1 week or up to 2 months, depending on how you store it.
If you plan to use it within the week, refrigerate the tomato sauce in an airtight container for 5 days.
Anything longer and the sauce will either need to be frozen in an airtight container for 3 to 4 months or canned and stored in the pantry for up to a year.
How to Thicken Tomato Sauce in a Slow Cooker
Nothing can thicken up a sauce, gravy, soup, or roux like starch! Whether that’s cornstarch, arrowroot, or tapioca.
To thicken tomato sauce, add 2 teaspoons to a tablespoon of starch to the sauce. Stir to combine and cook for 10 minutes- it will thicken!
How to Pack Pasta and Tomato Sauce for Lunch
If you make this tomato sauce for dinner, why not pack it for a delicious hot lunch the next day? It’ll take care of those leftovers and give everyone a break from the usual salad/sandwich option.
You can even pack it with zucchini pasta for a low carb version. My kids even enjoy it too!
In the morning, reheat the pasta, or zucchini pasta, and sauce. Pack into thermos container and seal. Easy enough, right?!
