Creamy Seafood and Dill Casserole Over Rice
Cooking shrimp and scallops on high heat for three minutes prevents moisture loss while building immediate fond in a non-stick skillet. Evaporated milk provides the body of heavy cream without excess fat, reducing cost while maintaining emulsion stability under heat. Cornstarch acts as the thickening agent, forming a network of starch molecules that trap liquid when heated with stock and Dijon mustard.
Fresh seafood releases varying amounts of water during cooking. Whisking cornstarch directly into cold stock and milk before adding it to the skillet prevents clumping. The mustard adds emulsifying compounds that help bind dairy fats and cooking liquids into a cohesive sauce.
Broiling the assembled casserole for one minute under direct radiant heat caramelizes the seasoned bread crumbs and parmesan cheese without overcooking the shrimp or scallops beneath. Watching this final stage closely prevents the dairy and bread crumbs from burning.
Leftovers stored in an airtight container for up to two days retain adequate moisture if reheated gently over low heat. Rice absorbs excess liquid during storage, so adding a tablespoon of stock before warming restores the original sauce consistency.
