Halve the butternut squash, remove the kernels with a spoon and then peel. Cut the pumpkin into 1 cm cubes. Peel the sweet potatoes and cut into cubes approx. 1 cm in size. Rinse baby spinach under cold running water and drain in a colander.
Cook the pumpkin and potato cubes in a saucepan with a little salted water for approx. 20 minutes until soft and then drain.
In the meantime, mix the ricotta with the parmesan and eggs and season with salt and pepper. Grease a baking dish. Take the pasta dough out of the packaging and cut in half with a knife. So you have four large sheets of lasagne.
Place a lasagne plate in the baking dish. If corners stick out, cut them off with a knife. Put a layer of pumpkin potatoes on top, then spinach and a few pine nuts and finally the ricotta, parmesan and egg mixture.
Repeat the process and finish with the ricotta-parmesan-egg mixture.
Bake in a preheated oven at 220 degrees top / bottom heat for about 15 minutes.
