Preheat oven (electric cooker: 175°C/circulating air: 150°C/gas: see manufacturer). Wash pumpkin, dab dry, quarter and remove seeds and fibres. First cut the pumpkin into thin slices, then halve them crosswise.
Peel the garden pumpkin. Peel and finely chop the garlic. Wash parsley, shake dry, chop leaves.
Line a baking tray with baking paper. Mix pumpkin, garlic, 4 tbsp. oil, approx. 1 1/2 tsp. salt, 1/2 tsp. pepper and approx. 3/4 each of lemon peel and parsley. Spread on the baking tray. Bake in the hot oven for about 45 minutes.
Mash cheese with a fork and mix with crème fraîche. About 15 minutes before the end of the baking time, spread in splotches on the pumpkin.
In the meantime dab the fillets dry. Heat 1 tablespoon of oil in a large frying pan. Fry the meat for 5-6 minutes. Sprinkle with the rest of the lemon peel and parsley and fry briefly.
Season with salt and pepper. Wrap in aluminium foil and let it rest for about 5 minutes. Arrange everything. Baguette tastes good with it.
