Yield: 4 to 6 servings
Ingredients: Kosher salt; 3 tablespoons extra-virgin olive oil, plus more for brushing; 8 ounces spaghetti; 2 large eggs, beaten; 1/2 cup plus 2 tablespoons grated Parmesan cheese; 1 small onion, chopped; 1 small zucchini, chopped; 2 cloves garlic, chopped; 1 pound ground beef (85% lean); 1 teaspoon dried oregano; Pinch of red pepper flakes; 2 tablespoons tomato paste; 1 8-ounce can tomato sauce; 1 cup fresh ricotta cheese (about 8 ounces); 1 cup grated low-moisture mozzarella cheese (about 4 ounces)

Directions

Position a rack in the lower third of the oven and preheat to 425˚ F. Bring a large pot of salted water to a boil. Brush the bottom and sides of a 9-inch deep-dish pie plate with olive oil.
Add the spaghetti to the boiling water and cook as the label directs for al dente. Reserve 1 cup cooking water, then drain the spaghetti and shake the colander to remove the excess water. Put the spaghetti in a large bowl and toss with 2 tablespoons olive oil and 1 teaspoon salt. Add the beaten eggs and 1/2 cup Parmesan, then toss.
While the spaghetti cooks, heat the remaining 1 tablespoon olive oil in a large skillet over medium heat. Add the onion and zucchini and cook until softened, about 5 minutes. Add the garlic and cook until softened, 1 more minute. Crumble in the beef, season with 1/2 teaspoon salt and cook, breaking it up with a wooden spoon, until browned, 3 to 4 minutes. Stir in the oregano and red pepper flakes, then clear a spot in the center of the skillet and add the tomato paste. Let it toast for 30 seconds, then stir into the beef mixture. Add the tomato sauce, 1/2 cup of the reserved cooking water and 1/4 teaspoon salt, then bring to a simmer and cook until very thick, 3 to 5 minutes. Season with more salt to taste.
To assemble the pie, transfer the spaghetti mixture to the pie plate and press to form a crust with a flat bottom and slightly higher sides. Spread the ricotta in the spaghetti crust, leaving a border around the edges. Spoon the meat sauce on top, then sprinkle with the mozzarella and the remaining 2 tablespoons Parmesan. Bake until the bottom and sides of the pie are golden and the cheese is browned, about 25 minutes. Transfer to a rack and let cool 5 minutes before slicing.
