Baked Macaroni and Cheese with Breadcrumb Crust

Few pasta bakes are as direct and comforting as baked macaroni and cheese: short pasta folded through a smooth cheese sauce, baked until bubbling, then finished with a crisp topping. Here the sauce is the classic flour-and-butter base enriched with whole milk and mature Cheddar, giving it body, sharpness and a glossy texture that clings to the macaroni. Dijon mustard, black pepper and a little nutmeg sharpen the dairy richness without turning the dish away from its familiar, savoury character. The buttery breadcrumb crust adds the essential crunch, while a short rest after baking helps the centre settle for cleaner spoonfuls or slices. It works well as a vegetarian main, a generous side, or a make-ahead comfort dish for colder evenings.

Why this recipe works

  • Creamy sauce: A flour-and-butter roux thickens the milk into a smooth base that coats the macaroni evenly.
  • Crisp topping: Buttery breadcrumbs are added near the end of baking so they turn golden without drying out the pasta underneath.
  • Balanced richness: Dijon mustard and mature cheddar bring enough sharpness to keep the cheese sauce savoury rather than heavy.

Ingredient notes

  • Use mature cheddar: Mature cheddar gives the sauce a deeper, sharper flavour than mild cheddar, which can taste flat once baked.
  • Keep the seasoning subtle: Nutmeg, mustard and black pepper should support the cheese rather than dominate the sauce.

Texture tips

  • Stop the pasta early: Cook the macaroni just shy of al dente so it finishes in the oven without becoming soft.
  • Add breadcrumbs late: Scattering the breadcrumbs over the bubbling pasta keeps the topping crisp while the centre stays creamy.

Make-ahead tips

  • Assemble in advance: The macaroni and sauce can be assembled ahead and chilled before baking; add the breadcrumb topping just before it goes into the oven.
  • Reheat gently: Reheat covered in a 180°C (355°F) oven until piping hot, adding a little milk if the sauce looks dry.
  • Freeze in portions: Cool completely, freeze in portions, then defrost overnight in the fridge before reheating.

Common mistakes

  • Adding milk too quickly: Whisk the milk in gradually so the roux loosens smoothly and the sauce does not turn lumpy.
  • Overheating the cheese: Take the pan off the heat before stirring in the cheddar to help the sauce stay glossy rather than oily.
  • Serving immediately: Let the bake stand briefly so the sauce settles and the portions hold together more cleanly.

  1. Heat the oven to 200°C (390°F). Bring a large pot of well-salted water to the boil.
  2. Cook the macaroni until just shy of al dente, about 1 minute less than the packet suggests. Drain well in a colander and set aside.
  3. In a saucepan over medium heat, melt 40 g of the butter. Whisk in the flour and cook for 1 minute until it smells biscuity but has not browned.
  4. Gradually whisk in the milk until smooth, then bring to a gentle simmer, whisking often. Cook for 4 to 6 minutes until thick enough to coat the back of a spoon.
  5. Take the pan off the heat and whisk in the Dijon mustard, salt, nutmeg and pepper. Stir in the cheddar cheese until melted and glossy.
  6. Fold the macaroni into the cheese sauce, then scrape into a baking dish and level the top. Bake for 15 minutes until bubbling around the edges.
  7. Meanwhile, melt the remaining 20 g butter and mix with the breadcrumbs until evenly coated. Scatter over the bubbling macaroni cheese and bake for 8 to 10 minutes until golden and crisp.
  8. Leave to stand for 5 minutes before serving so it sets slightly and slices more neatly. Serve hot.

Recipe notes

Tips

  • Undercook the macaroni slightly so it stays tender after baking rather than turning soft.
  • For the neatest slices, let it stand the full 5 minutes, then cut with a sharp knife and lift with a spatula.

Substitutions

  • Replace Cheddar cheese with Gruyere cheese for a nuttier, slightly sweeter finish.
  • Replace Dijon mustard with whole-grain mustard for a milder heat and a little texture.

Storage

  • Refrigerate up to 3 days
  • Cool completely, then cover and refrigerate. Reheat in a 180°C (355°F) oven until piping hot; add a splash of Whole milk before reheating if it looks dry. Freeze in portions for up to 2 months and defrost overnight in the fridge before reheating.
