Notes
Prep Tip - The chicken can be cut into bite-sized pieces and added to the casserole instead of leaving as full breasts. The chicken tends to be more tender when baked this way.Meal Prep Tip - This casserole can be divided between four oven-safe glass containers (each covered tightly with aluminum foil) and baked at 375F for 1 hour. Remove from the oven, uncover, and allow to cool before covering with a lid and storing in the fridge for up to 5 days. Reheat in the microwave. Watch the video HERE.
