Preheat oven to 325 degrees. In a large pot, cook the pasta in chicken broth until al dente.
In a sauce pan, melt the butter and saute onions until edges are browned and caramelized. Add the seasonings, and the 1/2 cup chicken broth, and simmer for 2 minutes.
Add the sour cream. Mix well and remove from heat.
In a 13 x 9 baking dish, add in the pasta, sauce & shredded cheese. Mix well.
Bake for 15 minutes. Arrange the sliced cheese across the top. Then sprinkle the pickled peppers and a little paprika on top of the cheese. Bake for an additional 10-15 minutes, until cheese is melted and starting to brown.
