A lower-calorie way to make Cauliflower cheese
Cauliflower cheese with a lighter mustard sauce and crisp crumbs
Roasted cauliflower, a measured mature Cheddar sauce and wholemeal crumbs make a bubbling side at about 315 calories per serving.
Cauliflower cheese turns watery when the florets are boiled and buried under sauce. Roasting drives off moisture and adds browned edges first. A modest sauce made with semi-skimmed milk, mustard and strongly flavoured mature Cheddar then coats rather than floods the cauliflower, while crumbs give the top a dry crunch.
What changes—and what stays
From often 450–600 kcal with butter, cream and a heavy cheese layer to 315 calories
Roast 1.4 kg cauliflower dry and use 160 g mature Cheddar plus 25 g butter across six portions. Deeply browned florets, English mustard, nutmeg, mature Cheddar and toasted crumbs create savoury intensity without cream.

How the flavor stays
Deeply browned florets, English mustard, nutmeg, mature Cheddar and toasted crumbs create savoury intensity without cream.
A cost rule that survives inflation
Cauliflower, milk and breadcrumbs are inexpensive staples, and a mature cheese provides more flavour per gram than a mild larger block.

Method
Each step includes heat, a visible cue, and a recovery.
Step 1 · follow the visible cue
Roast the florets dry
Spread equal florets on two hot trays and roast at 220°C until tender with browned edges, without crowding.
Look for: The stems yield to a knife and the trays are dry, with no puddle of cauliflower water.
Step 2 · follow the visible cue
Cook out the flour
Melt butter, stir in flour and mustard and cook for two minutes before adding warm milk in several additions.
Look for: The paste smells lightly toasted and the sauce is smooth without flour lumps or raw aroma.
Step 3 · follow the visible cue
Melt measured cheese off heat
Simmer until the sauce coats a spoon, remove from the heat and stir in most of the grated mature Cheddar.
Look for: The sauce is glossy and flowing, with no oil split around the edges or cheese strings.
Step 4 · follow the visible cue
Coat lightly and brown
Fold sauce through cauliflower, top with remaining cheese and crumbs and grill until bubbling and deeply golden.
Look for: Each floret has a thin coating and the top is crisp without liquid gathering beneath.
