In a large bowl, whisk the eggs, then mix in our ricotta, Parmesan, Italian seasoning, garlic powder, salt, and pepper.
Add the cooked and cooled spaghetti and toss to coat evenly.
Preheat the oven to 375°F and grease a 9-inch pie dish.
Press the spaghetti mixture into the dish, forming a "crust." Be sure to really pull and form the spaghetti up the sides, like a nest that can hold the sauce and the cheese.
Spoon your sauce over the spaghetti base.
Top with shredded mozzarella.
Bake for 30-35 minutes, or until the cheese is bubbly and slightly golden.
Let cool for 5-10 minutes before slicing.
Garnish with fresh basil if desired. Slice and serve like a pie!
