Begin by bringing a large pot of salted water to a rolling boil. Add the spaghetti noodles and cook according to package instructions until al dente, about 8-10 minutes. Drain and set aside.

In a medium saucepan, heat olive oil over medium heat. Add minced garlic and chopped onion, sauté for 2-3 minutes until fragrant.

Stir in crushed tomatoes, tomato paste, sugar, oregano, basil, salt, and black pepper. For spice, add red chili flakes. Simmer uncovered for 10-15 minutes until thickened.

While the sauce simmers, take mozzarella balls and press a half olive into each to create eyeballs.

Once the sauce has thickened, toss the spaghetti into the saucepan, ensuring all noodles are coated with the sauce.

Plate the spaghetti on a serving platter and nestle the mozzarella eyeballs on top for a spooky presentation.
