Follow this simple guide to create your Greek Beef Giouvetsi with Orzo:

1. Brown the Beef: In a large Dutch oven, heat the olive oil over medium-high heat. Add the beef pieces and brown them on all sides. Remove the beef and set aside.

1. Sauté Onions and Garlic: In the same pot, add the chopped onion and sauté for about 5 minutes until soft. Add the minced garlic and cook for an additional minute.

1. Add Tomatoes and Broth: Stir in the crushed tomatoes and beef broth. Combine well.

1. Season the Mixture: Add the dried oregano, ground cinnamon, salt, and black pepper. Bring the mixture to a gentle simmer.

1. Return the Beef: Place the browned beef back in the pot. Cover and let it simmer for 45 minutes, stirring occasionally.

1. Prepare the Orzo: Meanwhile, cook the orzo in a separate pot according to package instructions until al dente. Drain and set aside.

1. Combine: After 45 minutes, add the cooked orzo to the beef mixture, stirring gently to incorporate everything.

1. Bake: Preheat your oven to 350°F (175°C). Transfer the mixture to a baking dish, sprinkle with grated Parmesan cheese, and cover with foil. Bake for 30 minutes.

1. Uncover and Finish: Remove the foil and bake for an additional 15 minutes, allowing the cheese to become golden and crispy.

1. Garnish and Serve: Remove from the oven and let it cool slightly. Garnish with fresh parsley before serving.
