In a large bowl, whisk together the egg, chopped parsley, tomato paste, dried oregano, salt, pepper, minced garlic, and water. Add ground beef, ground pork, bread crumbs, and freshly grated Parmigiano-Reggiano. Gently combine by hand until just incorporated, avoiding overmixing to maintain tenderness.

Form the mixture into golf ball-sized meatballs and arrange them spaced apart on a baking tray. Bake for 10 minutes, then flip each meatball and bake for another 10 minutes until browned and nearly cooked through.

While the meatballs bake, melt unsalted butter in a large skillet over medium heat. Add the finely chopped yellow onion and sauté for about 5 minutes until soft and translucent. Incorporate the minced garlic and cook for an additional minute until fragrant.

Pour the high-quality marinara into the skillet. Add the granulated sugar, salt, and black pepper. Stir and bring the sauce to a gentle simmer. Allow the flavors to meld for several minutes.

Slowly drizzle in the heavy cream while stirring continuously. Maintain low heat to prevent boiling and curdling of the cream. Simmer for 2 more minutes to achieve a smooth, creamy consistency.

In a separate bowl, whisk together the all-purpose flour and water until smooth. Gradually whisk this mixture into the simmering sauce, stirring vigorously to avoid lumps. Continue cooking for a few minutes until the sauce thickens nicely. Adjust seasoning by adding extra garlic powder, sweet paprika, salt, or pepper as desired.

Gently add the baked meatballs to the sauce and carefully toss to coat evenly. Let the meatballs warm through for a couple of minutes.

Immediately add freshly boiled, drained spaghetti to the skillet containing the meatballs and sauce. Toss and cook for about 5 minutes, allowing the pasta to absorb the creamy sauce.
