Preheat your oven to 350° F. Cook the pasta and ramen according to package instructions for 1 minute less than required cook time.
While your pasta is cooking, make the cheese sauce: add 6 tablespoons of butter to a deep pan or pot over low heat. Once it has melted, whisk in flour. Continue whisking until the butter and flour becomes brown (around 1 minute). Whisk in milk, followed by heavy cream, along with smoked paprika, mustard, miso, msg, and hot sauce. Continue whisking until the mixture starts bubbling (do not let it scald).
Add 4 cups of the grated vegan cheese, 1 cup at a time, stirring it in until your sauce is smooth. Remove from heat. Scoop out about 1 cup of the cheese sauce.
When your pasta is ready (i.e., 1 minute from totally cooked), drain and place back in the pot it was cooking in over low heat. Add 1 tablespoon of butter and stir in until your pasta is evenly coated. Then, add the cheese sauce (minus the 1 cup you reserved). Stir until the pasta is evenly coated.
Add half the pasta into your pre-greased 4 quart (11¾” x 8” x 2 ½”) casserole dish. Then, sprinkle with half the remaining cheese. Add grated parmesan. Add the remaining pasta and sprinkle with remaining cheese. Drizzle the top with reserved cheese sauce. Place in your preheated oven and bake for about 35 to 40 minutes, until the top is just beginning to brown.
