Ingredient
Weeknight suppers demand something hearty yet straightforward, and this tuna mornay delivers precisely that kind of satisfying warmth. The combination of flaky fish and tender broccoli florets creates a substantial base, while a proper bechamel sauce enriched with sharp cheddar brings everything together in creamy harmony.
Building the sauce requires patience. You begin with a roux, cooking butter and flour until it smells faintly nutty, then whisk in warm milk gradually to avoid lumps. Off the heat, Dijon mustard and a dash of Worcester sauce add depth without overwhelming the delicate tuna. Folding in the cheese and fish at this stage keeps those chunks intact rather than breaking them down during baking.
Getting the Top Just Right
The final flourish matters. A scattering of parmesan and panko breadcrumbs creates a textural contrast against the soft pasta beneath. Twenty-five minutes in a hot oven transforms these simple toppings into a golden, crackling crust that yields to creamy layers below.
Let it stand briefly before serving. This resting period allows the sauce to settle so each portion holds its shape on the plate, offering that perfect ratio of crisp topping to velvety interior.
