Serving this casserole is all about enhancing its appeal. Think about pairing it with simple side dishes like steamed green beans or a vibrant salad for a refreshing contrast. For a cozy touch, serve with crusty bread to soak up the delicious sauce.
Storage and reheating tips
Leftovers can be a blessing! Store any uneaten casserole in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy it again, simply reheat in the oven at 350°F (175°C) until warmed through. For longer storage, you can freeze it—but be sure to wrap it tightly to prevent freezer burn.
