This stuffed spinach mozzarella chicken breast is a cozy, satisfying meal perfect for a busy weeknight or a casual dinner with friends. It transforms simple ingredients into a juicy, flavor-packed main course with a creamy spinach and cheese filling, topped with marinara and melted mozzarella. The leftovers are fantastic for sandwiches or salads the next day.
For a lighter version, use part-skim mozzarella and low-fat cream cheese. You can use frozen chopped spinach (thawed and squeezed very dry) instead of fresh. Letting the chicken rest after baking is crucial for juicy results. The stuffed chicken can be assembled and frozen before baking for up to 2 months.
