1. Cheesy Chicken and Rice Casserole

   Ground beef or turkey, taco seasoning, corn, beans, and tortilla chips topped with cheese. Serve with salsa and plain yogurt for a fast crowd-pleaser.

   Pasta, marinara, ricotta, mozzarella, and a handful of frozen spinach for an easy veggie boost. Assemble ahead and bake when ready.

5. Broccoli, Ham, and Cheese Bake
   Diced ham, frozen broccoli, pasta or potatoes, and a creamy cheddar sauce. Great for using holiday ham leftovers.

8. Mexican Layered Casserole (Enchilada Style)

    Sliced sausages, thinly sliced potatoes, bell peppers, and onions tossed with olive oil and herbs, roasted in a baking dish.

    Roasted eggplant, chickpeas, tomatoes, garlic, and feta for a vegetarian casserole with robust flavors.

    A hearty vegetarian alternative using lentils for protein under a mashed potato topping — great for meat-free Mondays.

    Sautéed mushrooms and chicken in a creamy herb sauce over rice or noodles; use pre-sliced mushrooms and rotisserie chicken to speed prep.
