Peel the onions. Cut crosswise 4 times from the base of the flower to about 1.5 cm before the root. Blanch the cut onions in a large pot of boiling salted water for 3-4 minutes.
Lift out and pat dry well.
For the dough, mix 200 g flour with 400 ml cold water until smooth. Season with 1 tsp salt, 1 tsp paprika and 2 tbsp herbs from Provence. Heat the oil in a fryer or pot to approx. 180 °C.
Dust the onions with flour first, then dip them into the dough, also spreading the dough in the spaces between the onions. Lift out onions, let them drip off a little and turn them into breadcrumbs or sprinkle them generously with breadcrumbs.
Bake in hot oil for 5-10 minutes one after the other until golden brown. Take out and let it drip off on kitchen paper.
