Ingredients:
- 1 lb Spaghetti or Linguine (broken in half)
- 4 cups Cooked Chicken, shredded or cubed
- 2 tbsp Extra Virgin Olive Oil
- 8 oz Cremini mushrooms, sliced
- 1 small Yellow onion, finely diced
- 3 cloves Garlic, minced
- 1/2 cup Unsalted butter
- 1/2 cup All-purpose flour
- 3 cups Chicken stock (low sodium)
- 1 cup Heavy cream
- 1/2 tsp Nutmeg
- Salt and cracked black pepper to taste
- 1 cup Freshly grated Parmesan cheese
- 1 cup Shredded Mozzarella or Gruyère
- 1/2 cup Panko breadcrumbs
- 2 tbsp Fresh parsley, chopped
Instructions:
- Preheat and Prep. Set your oven to 375°F (190°C). Boil your 1 lb of pasta in heavily salted water, but pull it out 2 minutes earlier than the al dente instructions on the box. Note: It should still have a firm bite in the center.
- Drain and Oil. Drain the pasta and toss it with a drizzle of olive oil. Note: This prevents the strands from turning into a giant gluey brick while you make the sauce.
- Sauté Mushrooms. Melt the 1/2 cup butter in your skillet over medium heat. Sauté the 8 oz of mushrooms until they are golden brown and the pan is dry.
- Aromatics. Add the diced yellow onion and 3 cloves of minced garlic to the mushrooms. Cook for about 3-4 minutes until the onions are translucent and fragrant.
- Build the Roux. Whisk in the 1/2 cup flour. Cook for 1-2 minutes until it smells slightly nutty and looks like wet sand.
- Liquid Gold. Slowly stream in the 3 cups of chicken stock and 1 cup of heavy cream. Whisk constantly until the sauce is silky and coats the back of a spoon.
- The Big Mix. Fold in the 4 cups of chicken, the undercooked pasta, and 1/2 cup of the Parmesan. Stir in the 1/2 tsp nutmeg, salt, and pepper.
- Assemble. Transfer everything to your 9x13-inch dish. Top with the remaining Parmesan, the 1 cup of Mozzarella, and the 1/2 cup of Panko.
- The Bake. Slide it into the oven for 25–30 minutes until the edges are aggressively bubbling and the top is golden brown.
- Garnish and Rest. Sprinkle with fresh parsley and let it sit for 10 minutes before serving to let the sauce set. > Chef's Tip: If your sauce looks too thick before adding the pasta, splash in a little bit of the pasta cooking water. The starch in that water helps keep the sauce emulsified and creamy rather than pasty.
