DIRECTIONS

  • Set oven to 350 degrees F.
  • Butter a 13 x 9-inch casserole dish (or a large oval casserole dish).
  • Cook the pasta in a large pot of boiling water until al dente (do not overcook the pasta, leave semi-firm as it will cook more in the oven) drain, then transfer to a large bowl.
  • Add in whipping cream and all three canned soups, cooked chicken or turkey, sour cream, Parmesan cheese, 1-1/2 cup grated cheddar cheese and frozen peas (if using) toss well to combine.
  • In a large skillet melt butter; add in the mushrooms and cook until all the liquid is removed (about 10 minutes).
  • To the skillet with the mushrooms, add in onions, garlic and jalapeño pepper (if using) sauté until onions are soft; add to the soup mixture.
  • Using a wooden spoon mix all ingredients together until well combined.
  • Season with seasoned salt and pepper (or white salt).
  • Transfer to prepared baking dish.
  • Cover with foil and bake about 30-35 minutes (or until hot and bubbly) uncover and sprinkle with about 1 cup grated cheddar cheese, return to oven and bake until cheese is melted (about 5-8 minutes).
