Wash the potatoes thoroughly and boil them covered in plenty of boiling water for about 25 minutes. In the meantime clean, wash and cut broccoli into florets. Steam broccoli covered in 1/2 litre of boiling salted water for about 5 minutes. Put the broccoli on a sieve and collect the broccoli stock. Clean the mushrooms. Peel and chop onion.
Finely dice the bacon as well. Cut ham into strips. Heat 1-2 tablespoons of oil in a frying pan, drain the bacon and finally fry the onions briefly, remove them and add 2 tablespoons of oil to the pan. Sauté the mushrooms vigorously while turning. Season with salt and pepper and put half of the onion-bacon mixture back into the pan. Dust with flour, sauté briefly and deglaze with broccoli stock and cream. Add ham, bring to the boil and simmer for about 5 minutes. Cut the rind off the raclette cheese. Grate cheese roughly. Stir 75 g cheese into the sauce, season with salt and pepper. Add broccoli to the sauce and fold in.

Cut potatoes into thick slices, put them into a wide casserole dish (approx. 22 cm wide / 34-35 cm long approx. 2.5 litres capacity) and add the mushroom-broccoli sauce. Spread the rest of the onion-bacon mixture on top. Sprinkle with rest of cheese. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 30 minutes
