Heat oven to 200C/180C fan/gas 6.
Heat the oil in a large frying pan, add
the garlic and cook for 1 min. Add the
mushrooms and thyme, then cook for
3 mins until they start to soften. Throw in
the spinach and stir until the heat of the
pan wilts the leaves. Remove from the
heat and stir in the soft cheese, 1 tbsp
of the Parmesan and some seasoning.
Put a quarter of the spinach mix on the
bottom of a medium-sized baking dish,
lay 2 pasta sheets on top, then repeat
until you have used all the pasta. Finish
with the final quarter of the spinach mix,
sprinkle over the rest of the Parmesan,
then bake for 35 mins until golden and
the pasta is tender.
