Wondering how to make homemade spaghetti sauce? Look no further. This Crockpot Spaghetti Sauce is the BEST!

I grew up in a family where we never ate jarred sauce, but I’m always surprised at how many people do!

It’s SO much cheaper to make your own sauce. Plus, it’s easy to do and it tastes way better than anything you’ll find at the store!

Being Italian, sauce and pasta are staple dishes in my family.

Sauce is easy to make on the stovetop, but when you allow your crockpotto do the work – it’s even better.

The tomatoes cook low and slow leaving you with a rich spaghetti sauce that is so yummy!

How to Make Crockpot Spaghetti Sauce

1. Cook your onions/garlic in olive oil on the stove until translucent.

If you can give it a stir occasionally that’s great too – but if not, it will still be delicious!

Slow Cooker Tomato Sauce Tips

• This does make a good amount of sauce. If you’re just one or two people, I recommend making the full recipe + freezing half of it. I store my sauce in containers and just pop it in the freezer.. then when I need a fast dinner or lunch, I will take it out of the freezer the night before, defrost + cook
• Add meat for flavor: I love this Healthy Turkey Meatballs recipe or our Homemade Meatballs for adding into the sauce!
• Use fresh herbs if you can.. they just taste 100x better and give SO much flavor!
• You can also use this sauce in recipes like my Crockpot Stuffed Peppers, Turkey Bolognese Stuffed Zucchini,or Unstuffed Pepper Bowls

Adding meat to this sauce:

What I always do with my sauce is add my Healthy Turkey Meatballs or sausage to it to cook. I’ll bake the meatballs the day before I’m going to make sauce and then just put the completely cooked meatballs right into the sauce while it cooks in the crockpot.

It makes the meatballs SO tender.. they literally fall apart! It’s hard to find Whole30 sausage from the store that is good for sauce… I’d check with a local grocer/farmer if you can because they typically don’t add fillers/funky ingredients to their meat.

Whether you add meat or stick to meatless, this Healthy Crockpot Tomato Sauce is LOADED with flavor and super easy to make.

Ways to Use Slow Cooker Tomato Sauce

Here are our favorite ways to use crockpot tomato sauce:

• over pasta- theseHomemade Ricotta Cavatelli are my favorite!
• over zucchini noodles
• mixed in with Whole30 Stuffed Peppers
• Freeze it for another day
• Add a little bit to this Healthier Alfredo Sauce to make a creamy red pasta sauce
• with Homemade Ground Beef Meatballs or Healthy Turkey Meatballs

You can also try thisRosemary Chicken Sauce or Healthy Bolognese if you’re looking for a higher protein sauce with meat or if you’re looking for a cream sauce, try Healthy Alfredo Sauce or Lemon Cream Sauce.

How to Thicken Spaghetti Sauce:

This spaghetti sauce is thick as is. If you want to make it thicker, you can try cooking it for longer or adding some tomato paste.

Turn your slow cooker on high to try to thicken it. Be careful to watch your sauce towards the end because it could burn.
