In a large heavy bottom pot over medium-high heat, add a drizzle of olive oil and the ground chuck and Italian sausage. Crumble the meat down as much as possible.
Add the onions and garlic and a pinch of salt. Stir and cook for 5 minutes until the onions are softened.
Add the oregano, chili flake, tomato paste, and beef bouillon. Stir and cook for 2-3 minutes.
Pour in the crushed tomatoes, water, sugar, and fresh basil. Stir to combine.
Break the spaghetti in half and add it to the sauce. Simmer for 1 minute.
Transfer the pot to the oven and bake at 425°F for 16-18 minutes, stirring halfway through, until the pasta is tender.
Remove from the oven, stir in the parmesan, and serve.
