Preheat the oven to 400°F (200°C). Cook spaghetti according to package directions until al dente. Drain thoroughly and transfer into a greased 9x13-inch casserole dish.
Layer with cheese and seasoning
Dot the cooked pasta evenly with ricotta cheese. Sprinkle garlic powder and Italian seasoning over the surface for added flavor.
Add sauce and turkey
Pour the spaghetti sauce evenly over the pasta and ricotta. Distribute the shredded turkey across the top, ensuring it is spread evenly.
Top with cheeses and bread crumbs
Sprinkle shredded mozzarella cheese over the turkey and sauce, followed by the parmesan cheese. Finish with a layer of Italian bread crumbs for added crispness.
Bake the casserole
Place the dish in the preheated oven and bake uncovered for 15 minutes, or until the cheese has fully melted and the bread crumbs are golden brown.
Garnish and serve
Remove from the oven and garnish with freshly chopped basil before serving warm.
