Tips for the Best Weeknight Casseroles

• Use cooked chicken. Rotisserie or leftover chicken saves loads of time.
• Grease the dish. A well-greased dish keeps casseroles from sticking.
• Do not overfill. Leave a little room so the casserole does not bubble over.
• Add a cheese layer. A middle layer of cheese adds flavor and richness.
• Keep toppings crisp. Add crunchy toppings just before baking.
• Drain the meat. Draining excess fat keeps the dish from getting greasy.
• Pre-cook watery veggies. This keeps the casserole from turning soupy.
• Let it rest. A few minutes of resting helps the layers set before serving.
• Bake on a sheet. A baking sheet underneath catches any drips.

How to Make Ahead and Store Casseroles

One of the best things about weeknight casseroles is how well they fit into a busy schedule. Many can be assembled ahead of time, covered, and refrigerated, then baked fresh when you are ready for dinner. This makes them perfect for prepping on a calm afternoon and pulling out on a hectic evening.

Most weeknight casseroles also freeze beautifully, which makes them ideal for batch cooking. You can assemble a second casserole, freeze it before baking, and thaw it in the refrigerator overnight when you want a homemade meal with almost no effort. For dishes with a crunchy topping, it is often best to add the topping just before baking.

Leftovers store well too. Let the casserole cool, then keep it in an airtight container in the refrigerator for a few days. Reheat individual portions or a larger dish in the oven to keep crispy toppings crisp, making these weeknight casseroles a gift that keeps on giving all week long.
