Heat 3 tablespoons of olive oil in a large pot or Dutch oven over medium heat. Add the finely chopped onion and sauté, stirring occasionally, until softened and translucent, about 5-7 minutes.

Add the ground beef to the pot, breaking it up with a wooden spoon. Increase heat to medium-high and cook until the beef is thoroughly browned, about 8-10 minutes. Drain off any excess fat from the pot if desired.

Stir in the minced garlic and tomato paste, cooking for 1 minute until fragrant. If using, pour in the red wine and bring to a simmer, scraping up any browned bits from the bottom of the pot. Cook for 2-3 minutes until the wine has slightly reduced.

Add the crushed tomatoes, beef broth (or water), cinnamon stick, bay leaves, dried oregano, 1 teaspoon of salt, and 1/2 teaspoon of black pepper. Stir well to combine all ingredients. Bring the sauce to a gentle simmer, then reduce the heat to low, cover the pot, and let it cook for at least 45-50 minutes, stirring occasionally, until the sauce has thickened and the flavors have deeply melded. Remove the cinnamon stick and bay leaves before serving.

About 15 minutes before the meat sauce is ready, bring a large pot of salted water (1 tablespoon salt) to a rolling boil. Add the pasta and cook according to package directions until it is al dente (firm to the bite).

Drain the pasta well. You may toss it with a teaspoon of olive oil to prevent sticking if desired.

To serve, you can either combine the drained pasta directly into the pot with the meat sauce and toss to coat, or portion the pasta onto individual plates and spoon a generous amount of the Makaronia me Kima sauce over the top.

Garnish each serving generously with freshly grated Kefalotyri or Parmesan cheese.
