There are many mac n cheese recipes out there, but this is the classic. Baked in the oven with deep savoury flavours like bay and mustard, this is the pasta recipe you’ll come back to time and time again.
Mac n cheese is a cheesy pasta classic, but I have a couple of interesting bits in this mac n cheese recipe that might seem unusual at first. I don’t soften the onion before adding it to the sauce. There are a few reasons for this – firstly, it works to impart as much of that fresh, zingy onion flavour as possible – important to cut through the richness. Secondly, it adds a nice texture to the mac n cheese. Of course, the onion cooks while the pasta is baking in the oven, so it’s not really raw at the end. Give it a go – you’ll like it!
I also use whole grain mustard (and a fair amount of it). This adds a gentle mustard flavour that works well with the cheese and makes the dish reminiscent of a rarebit.

The Ingredients
- Macaroni – it’s called mac and cheese for a reason! If at all possible, use macaroni in this recipe. If you can’t, use the shortest pasta you can find – you want to get one a similar size to macaroni.
- Butter, flour, milk – these are the ingredients that make your white sauce. Use salted or unsalted butter – either is fine. Use plain flour. You can use skimmed, semi skimmed or whole milk.
- Cheddar cheese – for me, in this classic mac n cheese, it’s got to be cheddar. It has a nice strong flavour and melts into the sauce well – everything you need.
- Bay leaves, onion, whole grain mustard – these are my little additions that make this classic the best. It tastes SO savoury and you won’t be able to stop eating it! If you can, use fresh bay leaves.
