Preparation Preheat the oven to 180°C. Peel the asparagus and cut them diagonally into slices. Set the tips aside for finishing. Slice the shallots into thin rings and cut the guinea fowl into cubes.
Making the base of the lasagna Melt the butter in an ovenproof pan. Sauté the shallot until it becomes translucent. Add the guinea fowl, season with pepper and salt, and briefly fry.
Preparing the sauce Whisk the cornstarch into the cream and add it to the pan. Pour in the chicken broth and add half of the cheese. Season again with pepper and salt and mix well.
Assembling the lasagna Break the lasagna sheets and mix them into the whole. Stir in the asparagus pieces (except for the tips). Finish with sage leaves, the remaining cheese, asparagus tips, and cheddar.
Baking Place the pan in the preheated oven and bake for 25-30 minutes until the top is golden brown and crispy.
Tips
Saving asparagus disputes: Do not throw away the asparagus disputes! Freeze them in until you have enough to make a delicious asparagus soup, of which I also have a vegan version!
