Notes
You can easily double this recipe by using a larger crock pot.
For a quick swap, use canned mushrooms in place of fresh mushrooms in this recipe.
The Homestyle or Swedish flavor of meatballs work best for this.
We usually serve these meatballs over noodles, rice or mashed potatoes.
For some additional spice you can stir in some paprika or cayenne pepper.
Heavy cream can be substituted for the sour cream.
The Crock Pot Meatball Stroganoff Recipe will stay good for up to 4 days covered in your refrigerator. To reheat place in a microwave or pot on the stove. You might need to add a splash of milk. I would recommend not mixing it with the pasta because it will taste better and is easier to warm up when kept separated. The noodles will soak up the sauce and make the dish very thick and heavy.
