Can I use frozen chicken for this recipe?
Yes, frozen chicken works in a slow cooker, but add 1–2 hours to the cooking time. Ensure the chicken reaches 165°F internally before serving.
How do I prevent the potatoes from being mushy?
Quarter the potatoes to a uniform size so they cook evenly. Check at the 4-hour mark on low setting; don't overcook past tender.
Can I make this ahead?
Prep potatoes and chicken the night before and refrigerate in separate containers. Combine in the slow cooker in the morning. The parmesan sauce can be made 1 day ahead.
What if I don't have parmesan garlic sauce?
Mix ½ cup sour cream or heavy cream with ½ cup grated parmesan, 2 minced garlic cloves, salt, and pepper as a substitute.
Can this be doubled?
Yes, double all ingredients, but increase cooking time by 30 minutes on low. Ensure your slow cooker is large enough (6+ quart).
