Spinach pasta bake

1 onion

300g frozen spinach (defrost)

200g any pasta shapes

2 Tbsp butter

2 Tbsp flour

2 cups milk

salt, pepper, nutmeg

Melt the butter in a heavy-bottomed saute pan over medium heat. Add the onions and saute until translucent, about 10 minutes. Add the flour and nutmeg and cook, stirring, for 2 more minutes. Add the milk and cook until thickened. Squeeze as much liquid as possible from the spinach and add the spinach to the sauce. Season, to taste, with salt and pepper.

Mix the sauce with cooked pasta and transfer to a baking dish. Sprinkle with grated cheese on top. Bake for 20 minutes until hot and bubbly.
