A lower-calorie way to make Tuna pasta bake
Tuna pasta bake with sweetcorn, peas and yoghurt sauce
Tuna, wholemeal pasta, peas and sweetcorn bake in a lemony milk-yoghurt sauce for about 475 calories per serving.
Tuna pasta bake can be creamy without condensed soup or a thick cheese layer. A light milk sauce is cooled slightly before Greek yoghurt and lemon enter, preventing splitting. Tuna is folded through in large flakes, while peas and sweetcorn bring colour and enough bulk to keep the measured pasta portion satisfying.
What changes—and what stays
From often 620–800 kcal with condensed soup, mayonnaise and heavy cheese to 475 calories
Use spring-water tuna, 420 g dry pasta and 150 g Greek yoghurt, limiting cheese to 100 g for six portions. Lemon, mustard, parsley, tuna and a small amount of mature cheese create a bright savoury sauce that does not need mayonnaise.

Method
Each step includes heat, a visible cue, and a recovery.

Step 1 · follow the visible cue
Drain tuna without crushing flakes
Press tuna gently in a sieve and separate it into large pieces rather than mashing it into paste.
Look for: No water drips from the fish and recognisable flakes remain for the finished bake.

Step 2 · follow the visible cue
Cook pasta short and add vegetables
Boil pasta three minutes short of tender, adding peas and sweetcorn only for the final minute, then drain.
Look for: The pasta centre is firm and the vegetables are hot, bright and not wrinkled.

Step 3 · follow the visible cue
Cool sauce before adding yoghurt
Make a light flour-and-milk sauce, remove from heat for two minutes, then stir in yoghurt, lemon, mustard and parsley.
Look for: The sauce is smooth and tangy, without curds, oil or a raw flour taste.

Step 4 · follow the visible cue
Fold flakes and bake briefly
Combine gently, transfer to a dish, top with measured cheese and bake until bubbling and pale gold.
Look for: Tuna flakes remain visible and the creamy sauce coats pasta without a dry or greasy surface.
