A lower-calorie way to make Macaroni cheese
Macaroni cheese with cauliflower, peas and mature Cheddar
Measured macaroni, cauliflower and peas in a mustard Cheddar sauce create a creamy bake at about 465 calories per serve.
Macaroni cheese feels generous when sauce coats every curve, not when pasta and cheese are piled high. Cauliflower florets roast first so they stay distinct, peas add colour, and mature Cheddar brings flavour in a measured amount. Toasted wholegrain crumbs give the top a crisp finish without another cheese layer.
What changes—and what stays
From often 650–850 kcal with large pasta portions, cream and extra cheese to 465 calories
Use 420 g dry macaroni for six, add 900 g cauliflower and peas, and limit mature Cheddar to 180 g. Roasted cauliflower, mustard, nutmeg, sharp Cheddar and toasted crumbs create creamy, savoury contrast with less cheese.

Method
Each step includes heat, a visible cue, and a recovery.
Step 1 · follow the visible cue
Roast cauliflower until dry
Spread florets on a hot tray and roast until browned and just tender rather than boiling them in water.
Look for: The tray is dry, stems yield to a knife and the edges show dark toasted spots.
Step 2 · follow the visible cue
Cook macaroni just short of tender
Boil pasta two minutes less than the packet time, drain thoroughly and reserve a cup of cooking water.
Look for: The centre retains a firm line and the elbows are separate, not swollen or split.
Step 3 · follow the visible cue
Build a smooth mustard sauce
Cook butter and flour, whisk in warm milk, simmer to coat a spoon and melt cheese and mustard off the heat.
Look for: The sauce is glossy and loose enough to flow through pasta without oily separation.
Step 4 · follow the visible cue
Fold top and bake briefly
Combine macaroni, cauliflower, peas and sauce, top with crumbs and bake only until bubbling and golden.
Look for: Vegetables remain visible, crumbs are crisp and the sauce has not dried into a solid block.
