Fish Burger with Charred Lettuce and Tarragon Mayo

This fish burger features skinless white fish fillets lightly dusted in seasoned flour and pan-cooked for a tender inside with a light crust. The recipe includes a homemade tarragon mayonnaise that adds an herbal, creamy element. Charred large lettuce leaves bring a smoky, slightly wilted texture to the sandwich, which is served on soft bread rolls. The combination of grilled fish, charred greens, and fresh mayonnaise creates a balanced, fresh burger with layers of flavor and texture.

Description

The Fish Burger with Charred Lettuce and Tarragon Mayo is built around lightly floured white fish fillets pan-fried in olive oil to maintain juiciness while developing a slight crust. Charred lettuce leaves cooked in extra virgin olive oil add a smoky depth and balance moisture with a delicate crispness. The tarragon mayonnaise, made fresh by emulsifying egg yolk, mustard, lemon juice, and tarragon with oil, lends a herbal creaminess that complements the mild fish and brightens the overall flavor. Alternatively, a simple mix of store-bought mayo with chopped tarragon and lemon juice provides a quicker option.

The fish burgers are assembled by placing the cooked fish and charred lettuce inside soft bread rolls, with a squeeze of fresh lemon for added acidity. This recipe suits a lunch or light dinner where you want a fish sandwich with components that hold together well without becoming soggy.

The notes advise that various flaky white fish like barramundi, cod, haddock, or pollock can be used. Ensuring the fish is skinless helps keep the texture gentle. The fish is cooked briefly on each side to retain moisture. Charred lettuce adds an unusual smoky element that contrasts with the creamy, bright-tasting mayo. The rolls are sliced and ready to assemble just before serving to preserve freshness and prevent sogginess.
