Note
Storage: Refrigerate leftovers in an airtight container for up to 3 days. Reheat gently on the stovetop over low heat to prevent the sour cream from splitting.
Substitutions: You can substitute Greek yogurt for sour cream for a tangier flavor, or use a mix of cheddar and mozzarella instead of Swiss. If you don't have fresh parsley, dried parsley can be used (use 1 teaspoon instead of 3 tablespoons).
Variations: Add a splash of chicken broth if the sauce seems too thick. For extra creaminess, stir in a tablespoon of cream cheese along with the sour cream.
Tip: Ensure the chicken is fully cooked before adding it to the skillet to ensure food safety and proper texture. If using raw chicken, cook it separately first.
