Bring 5 quarts of water to a boil in a large pot. Adjust heat so that water boils very gently.

Preheat the oven to 350 degrees F (175 degrees C). Melt butter in a skillet over medium heat. Saute onion in butter until tender. Blend in 2 tablespoons flour until smooth. Pour in cream and broth and cook stirring constantly until thickened. Remove from heat and stir in half of the Parmesan cheese and half of the Jarlsberg until smooth. Pour over the dumplings in the dish. Sprinkle remaining cheeses over the top.
