Variations
If I want to mix things up, I can add a variety of veggies to the casserole. Mushrooms, zucchini, or even bell peppers would be great additions. For a lighter version, I can swap out the mozzarella and Parmesan cheese for lower-fat alternatives. I could also use ground turkey instead of chicken for a different twist.
Storage/Reheating
This casserole is fantastic for meal prep! I like to store it in an airtight container in the refrigerator for up to 3 days. To reheat, I place individual servings in the microwave for 1-2 minutes or bake the casserole in the oven at 350°F (175°C) for about 10-15 minutes until heated through.

Definitely! I can prepare the casserole, cover it, and refrigerate it until I’m ready to bake. Just add a few extra minutes to the cooking time if it’s cold from the fridge.
