Preheat the oven to 375F; get out a 1.5-quart casserole dish.
Add the butter to a medium skillet over medium heat. Once hot, add the onion and cook until softened, but not browned, about 3 minutes, stirring occasionally. Add the garlic and cook 1 minute more, stirring constantly. Add the broth and bring up to a simmer. Whisk in the cream cheese until smooth; let it simmer a couple minutes until thickened slightly, whisking frequently. Whisk in the Emmental cheese a handful at a time until fully incorporated. Stir in the parsley, Worcestershire, and black pepper. Remove from the heat.
Add the zucchini and chicken to the casserole dish and pour in the sauce. Sprinkle on the crisped pork belly and then the Parmesan. Cover with foil and bake until the zucchini is tender, about 45 minutes. Remove the foil and broil a couple minutes to brown the top.

This is a great use for leftover chicken, or store-bought rotisserie chicken.
Instead of pork belly, you can substitute 2 slices of crisped, crumbled bacon.
