Baked Mac and Cheese

Baked mac and cheese turns a simple pasta-and-cheese sauce into a proper oven-baked casserole, with tender macaroni held in a smooth Cheddar sauce and a crisp, buttery panko crust on top. The sauce follows the classic flour-and-milk base used for a creamy bake, while Dijon mustard adds a gentle sharpness that keeps the richness from feeling flat. It is the kind of American-style comfort dish that works as a generous vegetarian dinner, a side for a larger meal, or a make-ahead bake for sharing. Served bubbling from the oven after a short rest, it should be creamy underneath with enough golden crunch to make each spoonful satisfying.

Why this recipe works

  • Smooth cheese sauce: A simple flour-and-butter base thickens the milk before the Cheddar is added, helping the sauce coat the pasta evenly.
  • Crisp golden topping: Buttered panko bakes into a light, crunchy crust that contrasts with the creamy pasta underneath.
  • Balanced richness: Dijon mustard cuts through the richness of the cheese and milk without making the sauce taste overtly sharp.

Texture tips

  • For a smoother sauce: Add the grated Cheddar off the heat and stir it in gradually, so it melts gently rather than turning grainy.
  • Keep the pasta tender: Boil the macaroni until just al dente, as it will continue softening while the bake heats through in the oven.
  • For extra crunch: Spread the buttered panko evenly over the surface so it browns consistently instead of clumping in patches.

Ingredient notes

  • Cheddar choice: A mature Cheddar gives the sauce a fuller savoury flavour, while a milder Cheddar keeps the dish softer and more family-friendly.
  • Mustard balance: Dijon mustard adds gentle sharpness that stops the sauce feeling flat; whole-grain mustard gives a milder bite and a little texture.
  • Panko topping: Panko breadcrumbs stay lighter and crisper than fine breadcrumbs, making them especially good for baked pasta dishes.

Make-ahead tips

  • Assemble ahead: The pasta and sauce can be combined in the baking dish ahead of time; add the buttered panko just before baking for the best texture.
  • Reheat gently: If leftovers look dry, add a splash of whole milk before reheating in a 180°C (355°F) oven until piping hot throughout.
  • Freeze in portions: Cool completely, freeze in portions, then defrost overnight in the fridge before reheating thoroughly.

Common mistakes

  • Adding cheese over high heat: Take the sauce off the heat before stirring in the Cheddar; strong heat can make the cheese separate and turn oily.
  • Baking too long: Bake only until the edges are bubbling and the topping is golden, as extra oven time can make the sauce thicken too much.

  1. Heat the oven to 200°C (390°F). Melt 20 g of the unsalted butter and mix it with the panko breadcrumbs in a bowl until evenly coated. Set aside.
  2. Bring a large pot of water to the boil and season with 1 tsp of the fine sea salt. Cook the macaroni until just al dente, about 1 minute less than the packet suggests. Drain well in a colander.
  3. In a saucepan over medium heat, melt the remaining unsalted butter. Stir in the plain flour and cook for 1 minute, stirring constantly, until it smells lightly biscuity but has not browned. Gradually whisk in the whole milk until smooth.
  4. Simmer the sauce gently for 3 to 5 minutes, whisking often, until thick enough to coat the back of a spoon. Whisk in the dijon mustard, remaining fine sea salt, and black pepper. Take off the heat.
  5. Stir in the cheddar cheese a handful at a time until fully melted and smooth. Fold the drained macaroni through the cheese sauce until evenly coated. Tip into a baking dish and level the top.
  6. Scatter the buttered panko breadcrumbs evenly over the top. Bake for 18 to 20 minutes until bubbling at the edges and golden on top. Rest for 5 minutes before serving so the sauce settles slightly.

Recipe notes

Tips

  • For the best melt, grate the cheddar cheese and add it off the heat so the sauce stays smooth.
  • If you like a looser sauce, bake in a slightly larger dish so the pasta sits in a thinner layer and heats through quickly.
  • If serving vulnerable groups, ensure the sauce is properly heated through and bubbling before serving.

Substitutions

  • Replace Dijon mustard with whole-grain mustard for a milder heat and a little texture.
  • Replace Cheddar cheese with gruyere-cheese for a nuttier, more savoury finish.

Storage

  • Refrigerate up to 3 days
  • Cool completely, then cover and refrigerate. Reheat in a 180°C (355°F) oven until piping hot throughout; 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.
