This Slow Cooker Spaghetti Casserole is a family favorite and will be yours too. Cheesy, comforting, delicious and simple to make. You’re going to love it!
Happy Monday. I hope everyone had a great weekend.
I’ve been excited to share this recipe with you today. I love this slow cooker spaghetti casserole. It’s totally easy peasy. I love meals like this that are pretty much no brainers and require little or no effort. It’s as simple as browning your ground beef, throwing it in the slow cooker along with some dry, broken spaghetti noodles and then topping it off with store-bought pasta sauce and a can of tomatoes. You will have to grate some cheese . . . hopefully you can handle that.
This stuff is so delicious. My husband said he likes it even better than regular spaghetti. I served it with a salad and some garlic bread . . .a perfect, simple, & delicious meal!

My family really enjoyed this, and it was very easy to make. (One minor problem- my youngest child wasn’t keen on the fire roasted tomatoes, but it was easy to pick those out of her portion.)
Thank you for sharing a nice recipe.
Thanks Jocelyn. I actually put the fire-roasted tomatoes in the blender first so there were no pieces/chunks of tomatoes. I have a couple picky eaters and if they see any chunks of tomatoes, they pick them out so the blender thing worked great. Glad you enjoyed it.
That blender trick is a great idea! I will have to give it a try. Thanks again.
How many servings does this make?
If I double it for a large crock pot, would the directions change?
Hi Donna! This makes about servings. There shouldn’t be a need to change the directions if you double it and cook it in a larger slow cooker.
