Baked Macaroni and Cheese

Few oven-baked pasta dishes are as dependable as macaroni and cheese: short pasta coated in a smooth cheese sauce, finished in the oven until the top turns crisp and the edges bubble. This version follows the classic American style, using a butter, flour and milk base for a stable, creamy sauce, with Cheddar for sharpness, Dijon mustard for savoury depth and a little nutmeg for warmth. Breadcrumbs add the essential golden crust, while slightly undercooked macaroni keeps the bake from turning soft. It works as a comforting vegetarian dinner, a side dish, or a make-ahead bake for casual gatherings.

Why this recipe works

  • Smooth cheese sauce: A butter-and-flour roux thickens the milk into a stable base before the cheddar is melted in off the heat.
  • Golden topping: Breadcrumbs and reserved cheese create a crisp, savoury crust that contrasts with the soft pasta underneath.
  • Balanced richness: Dijon mustard and nutmeg cut through the dairy richness, giving the sauce depth without overpowering the cheddar.

Texture tips

  • Keep the pasta firm: Drain the macaroni just before it reaches al dente, as it will continue to soften while baking in the sauce.
  • Build the sauce gradually: Whisk the milk in slowly at first so the roux loosens evenly and the sauce stays smooth.
  • Let the top brown properly: Bake until the edges are bubbling and the breadcrumb topping is golden rather than merely dry.

Ingredient notes

  • Choose a good melting cheese: A mature cheddar gives the sauce a stronger flavour, while a milder cheddar produces a softer, creamier profile.
  • Use nutmeg lightly: Nutmeg should add gentle warmth in the background, not dominate the cheese sauce.
  • Changing the cheese changes the finish: Gruyere melts well and adds nuttiness, but it will make the bake taste less like a classic cheddar macaroni cheese.

Make-ahead tips

  • Assemble before baking: The pasta and sauce can be combined in the baking dish ahead of time, then topped and baked when needed.
  • Reheat covered first: Warm leftovers in a 180°C (355°F) oven covered until piping hot, then uncover briefly to re-crisp the topping.
  • Freeze in portions: Cool completely, freeze in portions, then defrost overnight in the fridge before reheating thoroughly.

Common mistakes

  • Adding milk too quickly: Pouring in all the milk at once can make the sauce lumpy; add it gradually and whisk until smooth before adding more.
  • Boiling the pasta too long: Fully cooked macaroni can become too soft after baking, so stop boiling while it still has a little bite.
  • Melting cheese over high heat: Take the sauce off the heat before adding the cheddar to help it melt smoothly without becoming grainy.

  1. Heat the oven to 200°C (390°F). Bring a large pot of well-salted water to the boil, then cook the macaroni until just shy of al dente. Drain well and set aside.
  2. Meanwhile, melt the butter in a saucepan over medium heat. Stir in the flour and cook for 1 minute, stirring constantly, until it smells lightly biscuity. Gradually whisk in the milk until smooth.
  3. Cook the sauce, whisking, for 3 to 5 minutes until thick enough to coat the back of a spoon. Take off the heat and stir in the Dijon mustard and nutmeg. Add most of the cheddar cheese, reserving a small handful for the top, and stir until melted and smooth.
  4. Fold the drained macaroni into the cheese sauce until evenly coated. Spoon into a baking dish and level the top. Sprinkle over the breadcrumbs and the reserved cheddar cheese.
  5. Bake for 18 to 20 minutes until bubbling around the edges and golden on top. Rest for 5 minutes so the sauce settles slightly before serving.

Recipe notes

Tips

  • Undercook the macaroni slightly so it finishes cooking in the oven and stays pleasantly firm.
  • For the smoothest sauce, add the milk gradually and whisk well before adding more, especially at the start.
  • If serving to vulnerable groups, use pasteurised milk and ensure the bake is piping hot throughout.

Substitutions

  • Replace Cheddar cheese with Gruyere cheese for a nuttier, more complex flavour.
  • Replace Dijon mustard with English mustard for a sharper heat.

Storage

  • Refrigerate up to 3 days
  • Cool completely, then refrigerate in a sealed container for up to 3 days. Reheat in a 180°C (355°F) oven, covered, until piping hot, then uncover for a few minutes to re-crisp the top. Freeze in portions for up to 2 months and defrost overnight in the fridge before reheating.
