Ingredients
For the pasta

For the cheese sauce
- 40g unsalted butter
- 40g plain flour
- 600ml whole milk, warmed

How to Make Delia Smith Macaroni Cheese with Bacon
- Prepare the oven: Preheat the oven to 200°C or 180°C fan. Place a shelf in the middle of the oven so the dish cooks evenly and the top browns nicely.
- Cook the macaroni: Bring a large pan of salted water to the boil. Add the macaroni and cook until just tender. Drain well and set aside.
- Make the roux: Melt the butter in a saucepan over medium heat. Stir in the flour and cook for about one minute, stirring constantly, until pale and smooth.
- Add the milk: Gradually whisk in the warm milk, a little at a time, until smooth. Continue cooking and stirring until the sauce thickens.
- Finish the sauce: Stir in the mustard and grated Cheddar. Season with salt and black pepper, then remove from the heat once the cheese has melted.
- Combine: Add the cooked macaroni to the cheese sauce and mix gently until evenly coated.
- Assemble the dish: Spoon the macaroni mixture into a lightly buttered ovenproof dish. Scatter the chopped bacon over the top, followed by the extra grated cheese.
- Bake: Place in the oven and bake for 20 to 25 minutes, until bubbling hot and golden on top.
- Rest before serving: Remove from the oven and allow to stand for 5 minutes before serving.
Tips
How do I stop the sauce from going lumpy?
Make sure the milk is warm and add it gradually while whisking constantly. This keeps the sauce smooth.
Can I make this extra creamy?
You can replace 100ml of the milk with double cream for a richer sauce.
How do I get a crisp topping?
Use mature Cheddar and spread it evenly. Placing the dish on the middle shelf helps even browning.
