Bring a large pot of salted water to a boil.Note: I use a 5 quart pot with about 4 1/2 cups water and 1 tablespoon salt. While the water is coming to a boil, let's cook the onions.
In a large saute pan, heat the olive oil over medium heat.
Sauté the onions and hot pepper flakes. Season with a pinch of salt and freshly ground black pepper. Saute 4 to 5 minutes until onions are translucent and soft.
While the onions are cooking add the pasta to the boiling water and cook al'dente according to package direction.Note: I used a protein plus pasta which cooks al dente in 10 minutes. By the time the pasta is cooked the onion mixture will be ready. Add in the chopped garlic and rosemary to the pan with onions. Cook 30 to 60 seconds.
Carefully and slowly pour in the white wine. Simmer until reduced to 1/2 or 1/3. About 1 to 2 minutes.
Pour in the beef broth. Bring to a simmer. Cook 2 to 3 minutes.
Add in about 2 tablespoons chopped parsley.
Add in the short-ribs. Give it a quick stir.
Drain the pasta and add it into the pan with the short-ribs. Turn off the stove.
Add another 2 tablespoons fresh chopped parsley. Add the grated asiago cheese.
Mix/stir until the cheese is melted.
Transfer to a serving bowl. Garnish with parsley and more cheese if desired.
Serve and enjoy.
