2fresh oregano springs (optional and can be replaced with 1 tsp dry oregano)
1cupshredded gruyere cheese
salt & pepper to taste
Heat a large pot over medium-high heat and add the OO. Add the onions and brown sugar. Cook about 5-8 minutes, stirring frequently, until softened and brown. Toss the mushrooms+garlic, season with salt and pepper, and cook until mushrooms are soft. Add the Worcestershire sauce and wine and let it cook into the onions.
Pour in the chicken broth and bring to a boil. Add your pasta, bay leaves and oregano, cook covered, stirring often until most of the liquid has been soaked up by the pasta and the pasta is al dente. Taste the pasta for doneness. Allow to cook more (if still crunchy), or allow some of the liquid to cook off. The pasta will absorb more of the liquid as it sits.
Stir in the sour cream+cream and half the gruyere cheese. Cook 2 minutes and then remove from the heat. Top with the remaining cheese (gruyere and parmesan) Let it sit uncovered for 5 minutes before serving.
