You will need a large 3-4 quart casserole dish for this recipe. We used a deep 9X13 casserole dish.
Yield:10-12 servings 1x
Prep:30 minsCook:45 minsTotal:1 hour 15 minutes
3cups low sodium chicken or turkey stock
2cups whole milk
2cups heavy cream
1/2pound Fontina cheese, shredded
1 teaspoon salt (if using salted stock, omit salt or salt to taste)
1/2 teaspoon freshly ground black pepper
1/4 teaspoon freshly ground nutmeg
5 tablespoons butter
2cups thickly sliced onion (slice onion in half vertically and lay flat, then slice with the grain into thick slices).
1 12–ounce package button mushrooms, cut into thick slices
3 tablespoons flour
Non-stick cooking spray
8ounces uncooked extra broad egg noodles (we used No Yolk brand)
1pound cooked turkey (white or dark) cut into bite sized pieces
2cups frozen green peas
2ounces finely shredded Swiss cheese
2ounces plain potato chips, crushed
Preheat oven to 375 degrees.
Place chicken stock into medium to large sauce pan and bring to a boil. Boil until reduced to one cup, letting two cups evaporate. This will give you a triple strength stock. Add all of the milk and cream and bring to hot but not boiling. Add Fontina cheese, salt, pepper and nutmeg, stir and keep mixture on medium low heat.
While stock is reducing, melt butter in a large pot over medium heat and add onions. Sauté for five minutes and add mushrooms. Sauté for five more minutes and add flour. Reduce heat and stir to make a roux. Cook for three minutes. Add hot stock and milk mixture to butter, mushroom and flour mixture one third at a time, stirring with a wooden spoon. This sauce will be intentionally thin.
Spray a 3-4 quart casserole dish with non-stick cooking spray and ladle in some sauce to coat the bottom.
Spread half the dry noodles, half the cooked turkey, half the frozen peas and half of the hot cream sauce. Repeat with remaining noodles, turkey, peas and sauce.
Mix the finely shredded Swiss cheese with the crushed chips in a small bowl and sprinkle over the top of the casserole. (if you used a smaller casserole dish and it is filled to the top, place a sheet of foil on the rack below the casserole to catch any drips).
Bake uncovered for 30-40 minutes. The liquid should be bubbling and hot. Place under brolier for a minute or two to brown and crisp the top if desired. Remove from oven and allow the casserole to set up for ten minutes before serving.
