Today I’m sharing how you can make tomato sauce in your crock-pot. Not just any tomato sauce my friends, but a delicious recipe that will lead your family to believe you must have hovered over your hot stove-top all day preparing it. In reality, 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.

So what are some perks to making tomato sauce in the crock-pot? Below are just a few:


Tomato sauce is very versatile. One batch can be used in several different recipes. Make several batches at once and put the leftovers in cans to be used at a later time. This allows you to quickly throw together a spaghetti dinner on those crazy busy nights.

Here are some suggested recipe from the MOMables blog in which you could incorporate this tomato sauce:

It’s Good For You:

Tomatoes are very good for you. They contain lycopene, which is a powerful antioxidant (which is important for protecting your cells & providing immune system support). A cooked tomato contains approximately 6 times as much lycopene as a fresh tomato.

Can Be Made Year Round:

I used canned tomatoes for this recipe, however, you can use fresh.

May Trick Picky Eaters:

My son would tell you he dislikes tomatoes and if I put it on his plate it would most likely trigger his gag reflex. However, one of his favorite meals is…spaghetti. He doesn’t like the texture or taste of a fresh tomato but when it is pureed and broken down and cooked with other seasonings, he gobbles it up. So if your child is anything like my son then this tomato sauce recipe is a great way to sneak in those ingredients your child won’t eat fresh.
