Slow Cooker Tomato Sauce made with meatballs served over cooked pasta makes a delicious meal any night of the week.
Cooking the sauce low and slow all day is another family friendly crock pot recipe. It also helps make the house smells like Little Italy!

My recipe for Homemade Tomato Sauce with Meatballs is one of those recipes that I don't really have a recipe. I mean, not one written down. It's a recipe I've developed over the 30 plus years I've been married.
This is the first time I'm actually writing it down. Silly, I know. But like any other good Italian cook I've always just added a little of this, a little of that and my delicious tomato sauce was made!
If you've been a follower of my site for awhile, you'll know that when I first was married I didn't know how to cook anything.
I finally asked my mom had to make homemade tomato sauce for meatballs. Of course my mom didn't have a recipe written down either. Over the years I've adapated the recipe my mom dictated to me over the phone with what my family enjoys.

Crock Pot Tomato Sauce
You can make this recipe in a crock pot or on top of the stove in a heavy pan. I like to use my crcok pot because there's no risk of burning the sauce while I'm busy working.
But when I'm pressed for time, I will put out my heavy saucepan and make it like I did when I was first married.
I hope you'll use this recipe as a guide and adjust the seasonings to your family's taste. Because that's what all good home-cooks do. We cook for our family.
How to Freeze Cooked Ground Beef
When I make homemade meatballs, I usually make more than my family will eat for one meal. What I like to do is make around 15 or 20 meatballs but only add 6 or 8 to the crock pot with the sauce ingredients.
Here's how to freeze cooked ground beef or partially cooked meatballs:
- Place the partially cooked meatballs on a baking tray lined with parchment paper.
- Allow them to cool slightly.
- Then place the baking tray in the freezer to flash freeze the meatballs for about 30 minutes.
- Once frozen, wrap them in aluminum foil and store in a freezer-safe plastic container or bag.
The next time you're making homemade tomato sauce, pull the frozen meatballs out of the freezer. Add them frozen to the slow cooker and they'll be cooked through by the time the homemade marinara sauce is done.
