Heat 1 tablespoon clarified butter in a small saucepan and fry the bacon strips in it until light brown. Add the onion cubes and stir-fry until translucent. Add the baked beans and heat. Turn off the stove.
Divide the beans between two ovenproof dishes. Make a well in the middle and break open 1 egg, slide in and season with salt. Bake the beans in the preheated oven at 200 ° (without convection) on the grid on the middle rack for 12 to 15 minutes, until the egg yolks just start to set.
Cut the bread into 4 strips each. Heat 1 tablespoon clarified butter in a coated pan and fry the strips of bread in it over medium heat until golden brown. Gradually add the remaining clarified butter. Serve the bread strips with the beans.
