Sauté the onion and garlic in oil. Add the penne (raw!) And sauté briefly. Deglaze with the bouillon. Add the bay leaf. Cover and cook over a medium heat for about 10 minutes, stirring occasionally, until the liquid has almost boiled down. Pull from the stove. Remove the bay leaf.
Mix the cream and cream cheese in a bowl. Season well, add half of the cheese.
Pour the pasta mixture into a greased casserole dish, pour the cream mixture over it, distribute it and sprinkle with the rest of the cheese.
