Steps

  1. Begin by bringing a large stockpot of water to a rolling boil. Add 2 teaspoons salt and 12 ounces spaghetti. Cook for 8-10 minutes until al dente – you want the pasta slightly firm as it will continue cooking in the oven. Test by biting a strand – it should have just a slight resistance in the center. Drain and rinse under cold water to stop the cooking process.
  2. Position your oven rack in the center and preheat to 375°F (190°C). Thoroughly butter a 9×13-inch baking dish, making sure to get into all corners to prevent sticking.
  3. Create your roux by melting 6 tablespoons butter in a medium sauté pan over medium heat. Once melted, add 6 tablespoons flour and cook for 2 minutes, stirring constantly. The mixture should smell nutty but remain pale in color – if it darkens too quickly, reduce heat.
  4. Gradually whisk in 3½ cups stock, about ½ cup at a time, waiting for each addition to be fully incorporated before adding more. This prevents lumps from forming. Cook for 3-5 minutes until sauce is smooth and coats the back of a spoon. When you run your finger through the sauce on the spoon, it should hold a clear line.
  5. Whisk in ¾ cup cream and remaining seasonings. The sauce should be thick enough to coat pasta but still flow easily – if too thick, thin with additional stock. Fold in turkey and peas, heating just until warmed through.
  6. Combine ½ cup breadcrumbs with ½ cup Parmesan in a small bowl. Layer pasta in prepared dish, pour over sauce mixture, then top evenly with breadcrumb mixture. Bake uncovered for 20 minutes until bubbling at edges. Finish under broiler for 1-2 minutes until golden brown – watch carefully to prevent burning.
