Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish and set aside.
Cook the spaghetti according to the package instructions until al dente. Drain and set aside.
In a large skillet, melt 2 tablespoons of butter with the olive oil over medium heat. Add the diced onion and sauté until softened, about 3-4 minutes.
Stir in the minced garlic and cook for 1 minute until fragrant.
Add the sliced mushrooms to the skillet and cook until they release their moisture and begin to brown, about 5-6 minutes.
Push the vegetables to the side of the skillet and add the remaining 2 tablespoons of butter. Once melted, whisk in the flour, stirring constantly to create a roux.
Slowly pour in the chicken broth while whisking to incorporate the roux. Then stir in the milk and heavy cream, cooking until the sauce thickens slightly, about 5 minutes.
Reduce the heat to low and stir in the grated Parmesan cheese until melted and smooth. Season the sauce with salt and black pepper.
Add the cooked turkey, thawed peas, and cooked spaghetti to the skillet. Toss everything to coat evenly with the sauce.
Transfer the mixture to the prepared baking dish. Sprinkle the shredded cheddar cheese evenly over the top, followed by the breadcrumbs.
Bake in the preheated oven for 20-25 minutes, or until the topping is golden and the edges are bubbly.
Let cool for 5 minutes before serving. Garnish with chopped parsley, if desired.
