Slow Cooker Fresh Tomato Sauce

Slow Cooker Fresh Tomato Sauce

Growing up, we had a huge garden and for some reason every year my dad would plant 6 tomato plants. Those of you that garden understands the magnitude of that decision. We would end up with so many tomatoes we didn’t know what to do with them.

We would try to use as many as possible and ended up making lots of pasta sauce. The beauty of pasta sauce is that you can freeze it for later. I no longer have a garden living in an apartment, but I still love my fresh tomato sauce. Usually, my family would blanch the tomatoes first, but this sauce does not require you to do that. So yay, fewer steps!

Soften and caramelize onions and carrot under the broiler. This gives a sweet and slightly smoky flavor.

Toss the tomatoes with the onion and carrots, spices and bay leave.

Cook for 8 hours, 4 on low and 4 on high. This should break down the tomatoes and give a great flavor. Just puree it with a hand blender, my favorite tool and you are done!
