There’s nothing like a comforting Seafood Gratin Bake on a busy evening. It’s the perfect combination of rich, cheesy goodness with the satisfying taste of the sea. When I make this dish, it’s like taking a little trip to the coast, right from my Manhattan kitchen. A while ago, my kids were curious about different seafood flavors, and making this gratin bake was such a delightful way to introduce them to try something new. Plus, it’s a one-dish meal—less cleanup for us busy parents! You might also like my [ Breakfast Potatoes Recipe ] which is equally delightful.
