Turn up the heat to medium and stir in the flour. Cook for 1-2 minutes. Slowly add the milk, using a whisk to stir (just stir, don’t whisk) it in.

Notes
Can you make it ahead?Yes, make up the dish and sprinkle with the cheese (but don't bake in the oven). Cover and refrigerate for up to two days.Take out of the refrigerator an hour before you want to cook it, to take the chill off the dish (and to help prevent cold spots upon heating) then place in the oven covered in foil at 190C/375F for 10 minutes, then a further 20-25 minutes uncovered. Check that it's piping hot in the middle before serving.Can you freeze it?Yes, make up the dish and sprinkle with the cheese (but don't bake in the oven). Cover and freeze.Defrost in the refrigerator overnight. Take out of the refrigerator an hour before you want to cook it, to take the chill off, then place in the oven covered in foil at 190C/375F for 10 minutes, then a further 20-25 minutes uncovered. Check that it's piping hot in the middle before serving.Which pasta shapes?I used rigatoni, but any large pasta shapes will work. spiralli, shells, fusilli and penne are all good options.Nutrition info is for one serving of this recipe (this recipe serves 6).
