Crawfish Gratin

Crawfish Gratin is a delectable and indulgent dish that combines the rich flavors of crawfish, cheese, and creamy sauce. This Louisiana-inspired recipe begins with succulent crawfish tails, which are cooked to perfection and then smothered in a velvety cheese sauce. The sauce, often made with a blend of cheeses like Gruyere and Parmesan, adds a luxurious and comforting touch to the dish. The crawfish and cheese mixture is then baked until golden and bubbly, creating a delightful contrast of textures. The result is a heavenly combination of seafood and cheesy goodness that is sure to please any palate. Crawfish Gratin is a true delight for seafood enthusiasts and a dish that will leave a lasting impression on those lucky enough to enjoy it.

A tasty, creamy, cheesy Crawfish Gratin usually served with crunchy garlic bread, crusty loaves and salad. This is a wonderful dish served as an entree for dinner. My husband heated the leftovers and made it a dip that he ate with crispy tortilla chips. Served with French Bread Crostinis would also be very good.
