Slow Cooker Sunday: Spaghetti sauce so easy you’ll never buy another jar

I’m going to let you in on my secret of what I do when I have friends coming over for dinner.

I purposely make something that will make the house smell insanely amazing when my guests walk in the door. And guess what — this spaghetti sauce works every time. The house smells so good that I can’t even explain it. Just being in the house while this is cooking will make you hungry.

And the best part is that it’s so easy to make. Especially since it’s made in a slow cooker. Really, the only thing that needs to be done when enjoying this sauce is to boil the spaghetti and make some garlic bread.

This sauce looks (and tastes) so rich and hearty. The only warning is that you may get hungry way before dinnertime when you smell this cooking.

A little tip: Make extra pasta for leftovers to warm up later in the week.
