Sauté the Vegetables: Heat 1 tablespoon extra virgin olive oil in a large skillet over medium heat. Add 1/2 small yellow onion, 2 garlic cloves, 1 small carrot, and 1 celery stalk. Sauté until softened, about 5 minutes.
Brown the Meat: Add 1 pound lean ground beef to the skillet. Cook, breaking it up with a spatula, until browned and fully cooked. Drain excess grease.
Simmer the Sauce: Stir in 1 can (14 ounces) crushed tomatoes, 1/2 cup tomato paste, 1/2 cup red wine, 1 teaspoon dried oregano, 1 teaspoon dried basil, 1 teaspoon kosher salt, and 1/2 teaspoon fresh ground black pepper. Bring to a simmer, reduce heat to low, and cook for 20–25 minutes, stirring occasionally, until the sauce thickens.
Cook the Pasta: Meanwhile, bring a large pot of salted water to a boil. Cook 12 ounces rigatoni according to package directions until al dente. Drain and set aside.
Assemble the Pasta Bake: Preheat the oven to 375°F. Grease a 9x13-inch baking dish. In a large bowl, combine the pasta with the sauce and stir until evenly coated.
Layer the Dish: Spread half the pasta mixture into the prepared baking dish. Dollop half of the 8 ounces whole milk ricotta cheese across the surface. Add the remaining pasta mixture, then top with the rest of the ricotta and sprinkle with 4 ounces mozzarella cheese.
Bake: Cover the baking dish with foil and bake for 20–25 minutes. Remove foil and bake for another 10–12 minutes, or until the cheese is bubbly and golden.
Garnish and Serve: Let the pasta rest for 5–10 minutes. Garnish with chopped parsley and serve hot.
