Slow Cooker Marinara Sauce

I’ve been trying to make as much in my slow cooker as I can lately.  Instead of having to stop whatever I’m doing to start making dinner, dinner is already done!  That’s such a great feeling! 

I feel like it gives me back time to spend with my family, walk my dog, or curl up with my latest book.

So, because I try to make all my sauces from scratch, I decided I might as well create a slow cooker version of my Homemade Marinara Sauce, and here we are with Slow Cooker Marinara Sauce.

Why make homemade marinara sauce?

As easy as it is to open a jar of marinara from the grocery store, you just can’t beat homemade. 

It’s not only super inexpensive, but it makes more than you get from a jar, and you can control the ingredients.

For example, I don’t want sugar in my marinara, but a lot of sauces from the store include it. 

Also, I can make my marinara sauce organic for way cheaper than buying organic sauce from the store!

Ingredients needed for this recipe (scroll down to recipe card for complete recipe):

• Canned crushed tomatoes
• Onion
• Garlic
• Bay leaf
• Fresh basil
• Dried oregano
• Red pepper flakes
• Salt, pepper
• Olive oil

Here, I use homemade marinara sauce in my Mushroom Kale Lasagna (shown below).

It’s layered between lasagna noodles, garlicky sautéed mushrooms and kale with a blend of cheeses.  Perfect for Meatless Monday!

How to use Slow Cooker Marinara Sauce:

• Dipping Calabrian Chili Garlic Bread, mozzarella sticks, fried ravioli or breadsticks.
• Great as a pizza sauce!
• Use it as the base in Mushroom Kale Lasagna (pictured above).
• Freeze it in small containers for ready-to-go homemade sauce.
• Feel free to drop some meatballs or Italian sausages in the sauce so everything cooks at the same time.

How long is homemade marinara sauce good for?  Can I freeze it?

Leftovers can be stored in an air-tight container in the fridge for up to 6 days. 

This marinara sauce can also be frozen in freezer bags or freezer-safe containers for up to 6 months.
