Step 1

Preheat the oven to 200C/400F (fan).

Step 2

Cook the pasta in boiling water for 1 minute less than the pack instructions. Then drain.

Step 3

While the pasta is cooking, melt the butter in a large frying pan over a medium-high heat.

Step 4

Once the butter has melted, gradually add the flour whilst constantly stirring with a whisk, until it becomes a thick paste.

Step 5

Gradually add the milk, whilst stirring with the whisk, until combined.

Step 6

Add in the cheese, reserving 1 heaped tablespoon of each type of cheese.

Step 7

By now the pasta should be ready. Add the cooked and drained pasta to the pan with the white sauce. Mix together until the sauce coats the pasta.

Step 8

Transfer the pasta to a baking dish and sprinkle on the reserved cheese and lightly cooked bacon.

Step 9

Bake in the oven for 15-20 minutes until golden brown.

Step 10

Sprinkle parsley on top, then serve.
