This base will provide the casserole with its delightful richness and flavor, bringing all the ingredients together seamlessly.
Step 3: Fold in the Goodness
Next, gently fold in the shredded boneless, skinless chicken breasts, fresh baby spinach, and artichoke hearts. Be sure to also add half of the shredded mozzarella cheese at this stage.
