Can I use a different kind of meat?
Meatballs - Use 1-2 pounds of frozen meatballs, cut the time down to 3 hours on high or 6 hours on low.
Ground beef - Be sure to brown and crumble the beef before adding to the slow cooker.
Chicken - You can use boneless chicken breasts or thighs. Use chicken or turkey gravy instead of beef. Shred the chicken before adding the noodles and sour cream.
Can I use low-fat or non-fat sour cream?Yes, but the consistency of the sauce will be thinner.Can I serve or rice instead of adding pasta?Yes! Forgo adding the pasta. Add the sour cream just before serving and serve over steamed rice.Could another type of pasta be used?Yes, any type of pasta will work great (8 ounces). Cook according to package directions and drain well before adding to the sauce.
