Step 1.
Heat the oven to 180°C/160°C fan.
Step 2.
Bring a large pot of well-salted water to the boil. Add the rigatoni and cook following pack instructions until firmly al dente. Do not over cook. Drain and set aside.
Step 3.
Meanwhile, in a medium saucepan, melt the butter over medium heat, then add the flour and whisk while cooking for 1-2 mins, stirring constantly, until it bubbles and begins to foam.
Step 4.
Gradually add in the milk, whisking constantly to avoid lumps. Cook for around 5-8 mins or until the sauce thickens. Add the mustard and remove from the heat.
Step 5.
Grate in ¾ of the cheddar cheese and all the Parmesan and stir until melted. Stir in the defrosted spinach and the just-cooked pasta and season to taste with salt, pepper and a very generous grating of nutmeg. Transfer to a buttered baking dish.
Step 6.
Add the remaining grated cheddar cheese to the top and bake in the preheated oven for 30-35 mins, or until the top is bubbling and golden. Remove from the oven and dust over with some extra Parmesan to serve, if you like.
