This one-pot mac and cheese recipe makes ultra-creamy stovetop mac and cheese in 25 minutes with no draining — a family favourite for busy nights. Everything cooks in a single pot: the pasta absorbs the milk as it cooks, which leaves a naturally thick, silky sauce that clings to every piece of macaroni. There is no separate sauce pan, no colander and very little washing up.
Why You Will Love This Recipe
It is quick, comforting and reliably creamy. Because the pasta cooks directly in the milk mixture, the starch released by the macaroni helps the sauce thicken without flour or a roux. Stirring often and adding the cheese off the heat keeps the sauce smooth rather than grainy. It is the kind of supper that works just as well on a rushed weeknight as it does as a cosy weekend treat, and children and adults tend to ask for seconds.
Ingredients
- 350 g elbow macaroni
- 480 ml whole milk
- 240 ml water
- 2 tablespoons butter
- 1 teaspoon Dijon mustard
- 1/2 teaspoon garlic powder
- 1/2 teaspoon salt, plus more to taste
- 1/4 teaspoon black pepper
- 200 g mature cheddar, grated
- 100 g mozzarella, grated
How to Make One-Pot Mac and Cheese
- Add the milk, water, butter, mustard, garlic powder, salt and pepper to a large, deep pan. Warm over a medium heat until the butter has melted and the mixture is just beginning to simmer.
- Stir in the macaroni, making sure it is mostly covered by the liquid. Reduce the heat to medium-low and cook for 10 to 12 minutes, stirring often so the pasta does not stick, until it is just tender.
- Take the pan off the heat. Add the cheddar and mozzarella a handful at a time, stirring until each addition has melted before adding the next.
- Leave the mac and cheese to stand for 2 minutes. It will thicken as it cools slightly. Taste, adjust the seasoning, and serve at once.
Tips for the Creamiest Sauce
Use whole milk rather than skimmed milk, and grate your own cheese if you can, as pre-grated cheese can melt less smoothly. Keep the heat gentle once the pasta is in the pan, and stir regularly to prevent sticking and to help the sauce come together. If the sauce seems too thick, stir in a splash of warm milk. If it seems too thin, leave it to stand for a few more minutes before serving. Always add the cheese off the heat so it melts gently instead of splitting.
Variations to Try
Stir in cooked broccoli, peas or sweetcorn for extra vegetables, or add crispy bacon, shredded chicken or sliced sausage to make it more filling. A pinch of smoked paprika, a spoonful of cream cheese or a little extra mustard will all change the flavour without changing the method. For a golden top, spoon the finished mac and cheese into an ovenproof dish, scatter over extra cheese and breadcrumbs, and grill briefly until bubbling.
Storage and Reheating
Cool any leftovers quickly and store them in an airtight container in the fridge for up to 3 days. Reheat gently in a pan over a low heat with a splash of milk, stirring until hot and creamy again. Freezing is not ideal, as the sauce can turn grainy when thawed, so this is best enjoyed fresh or from the fridge.
Frequently Asked Questions
Do I really not need to drain the pasta?
No. The pasta cooks in the milk and water, and the liquid that remains becomes the sauce. Draining it would remove the starch that helps the sauce thicken, so keep everything in the pot.
Why is my sauce grainy?
Graininess usually happens when cheese is added over too high a heat. Take the pan off the heat first, add the cheese gradually, and stir until it is fully melted before serving.
Can I use a different pasta shape?
Yes. Small shapes such as shells, fusilli or penne work well, although cooking times may vary slightly. Check the pasta a minute or two before the end of the suggested time and cook until just tender.
Can I make it ahead?
It is best served fresh, when the sauce is at its creamiest. If you do need to make it ahead, reheat it gently with a splash of milk and stir well to bring the sauce back together.
Conclusion
