Notes
Optional toppings are not included in nutritional information.If you do not have half and half, check out this article from The Suburban Soapbox on what half and half is and how to make your own. So, if you are like me and thought you had some, but turns out that you don’t, check it out and see if you have what you need to make your own half and half. You can put raw ground beef in the slow cooker, but most recipes have a step for browning the ground beef first to make sure that it is evenly cooked and the grease is drained. If you put the ground beef in the slow cooker raw, you will want to break it into little pieces first and then make sure that it’s fully cooked before consuming food. I have found that I prefer to cook it before adding it to the slow cooker because then I can drain the grease off of the meat.For this recipe we tend to use the traditional pasta noodle if we have it. However, don’t let that stop you from using other pasta noodles. I definitely encourage using what you have on hand. Don’t worry It will all taste fantastic.
