Cheese Sauce for Pasta
A dependable cheese sauce is a useful South African kitchen basic. The roux thickens the milk; the cheese provides flavour. Asking the cheese to do both jobs over fierce heat is how dinner becomes a bowl of salty gravel.

Smooth, glossy and pourable enough to coat pasta.
Milky, savoury and distinctly cheesy without raw flour.
What the record supports.
Flour-thickened milk sauces belong to European sauce traditions and have been adapted widely for macaroni cheese and pasta bakes.
This mature-Cheddar version is a local household guide, not an authentic Italian pasta sauce.
Every ingredient has a job.
Butter and flour
A cooked roux thickens milk without requiring cheese to overheat.
Milk
Milk provides the liquid body.
Mature Cheddar
Strong cheese gives flavour without needing an excessive amount.
Build it in order.
Mature Cheddar gives better flavour per gram than mild cheese. Pre-grated products may contain anti-caking starch and melt differently.
- 01
Cook equal masses of butter and flour for one minute without browning.
- 02
Whisk in warm milk gradually and simmer until the flour is cooked.
- 03
Remove from strong heat and add grated cheese in handfuls.
- 04
Season, then loosen slightly before using in a bake because the oven reduces it further.
Pasta that helps.
- Macaroni
- Pasta bakes
- Cauliflower and vegetable pasta
Substitutions
Gruyère adds nuttiness.
A portion of mozzarella adds stretch but little seasoning.
Common mistakes
Adding milk too quickly
Failing to simmer out the flour taste
Boiling after cheese is added
Making the sauce too thick before baking
Storage and freezing
Cover the surface and refrigerate for 2 days.
Freeze for 1 month; whisk thoroughly after thawing.
Warm slowly with milk while whisking.
Mustard powder sharpens mature Cheddar.
A breadcrumb top belongs to the bake, not the sauce itself.
Put the technique to work.
