A lower-calorie way to make Tuna Pasta Bake
Tuna Pasta Bake — with peas, sweetcorn and a thin cheddar crust
Wholewheat pasta, tuna and vegetables bake in a light milk sauce under a thin golden crust, about 480 kcal per serving.
Pasta is stopped well short of tender and the milk sauce cooked only until lightly thick. Drained tuna is folded in large flakes immediately before baking. A rested square should hold together with moist tuna flakes and firm pasta, without a dry centre or milky pool at the edge.
What changes—and what stays
From with mayonnaise, cream and a thick cheese layer often 650–900 kcal to 480 calories
Use wholewheat pasta, semi-skimmed milk and cheese only as a thin crust, keeping tuna in large flakes. Tuna, mustard, lemon, parsley, black pepper and mature cheddar provide salt, acidity and browned savouriness.

Method
Each step includes heat, a visible cue, and a recovery.
Step 1 · follow the visible cue

Whisk flour into cold milk and simmer until smooth and just thick enough to coat a spoon
Look for: The sauce falls in a broad ribbon without lumps, butter sheen or heavy thickness
Step 3 · follow the visible cue
Drain and fold tuna gently
Press excess spring water from the tuna and divide it into large flakes before one gentle fold
Look for: The flakes remain clearly visible and no watery liquid collects in the mixture
Step 4 · follow the visible cue
Bake a thin golden top
Add peas and sweetcorn, scatter cheddar only over the surface and bake until set
Look for: The top is evenly golden and a rested portion cuts cleanly without dry pasta
