The eggs can be poached ahead and stored in cold water in the refrigerator, but if so, be sure to undercook them slightly. Warm them in hot water before serving.
Though filling enough as a main dish, you can also serve smaller portions of this creamy, cheesy casserole as a tasty side to scrambled eggs. We enjoyed the way the Classic Melts cheese blend melted over the casserole; substitute cheddar cheese if you can't find this product.
