Slow Cooker Spaghetti Sauce

Slow Cooker Spaghetti Sauce is my recipe of the day with the blogging group Multicooker Monday. We post our favorite recipes using small appliances such as slow cookers and instant pots on the third Monday of the month.
And this month I am sharing my spaghetti sauce with meat recipe which is made in the slow cooker. The long cooking time ensures the meat is very tender. Plus the combination of ingredients is much better than just a ground beef only sauce.
I have been making spaghetti for years and years and this is pretty much how I do it every time. It’s not that difficult to get a good tasting sauce together. Making your own sauce can save you a lot of money over jarred sauce. As well, if you grow your own tomatoes, you can use the ones you have made into marinara.

I can almost smell that sauce and using the slow cooker gives the flavors lots of time to meld together.
agree!
This sounds wonderful! Letting all of those ingredients meld in the slow cooker sounds delicious.
Wow! I will definitely try this spaghetti sauce recipe this weekend for my kids. Love the blog!!!
Thanks. I hope they love it as much as our family does.
I really liked the combo of the sausage and the hamburger. It was really good with spaghetti noodles.
