Bring a large pot of water to a boil. Add about half of the salt, then cook the spaghetti until al dente according to the package directions.
Before draining, reserve about 240 ml of the pasta cooking water. Drain the spaghetti and set it aside.
While the pasta cooks, heat the extra-virgin olive oil in a large skillet over medium heat.
Add the diced onion and cook for 5–7 minutes, stirring occasionally, until softened and translucent.
Add the minced garlic and cook for 30–60 seconds, stirring constantly, until fragrant but not browned.
Pour in the crushed tomatoes and add the remaining salt. Bring the sauce to a gentle simmer and cook uncovered for 12–15 minutes, stirring occasionally, until slightly thickened.
Tear or roughly chop the basil leaves, reserving a small amount for garnish. Stir the remaining basil into the tomato sauce.
Add the drained spaghetti to the skillet and toss until evenly coated. Add reserved pasta water a little at a time, if needed, to loosen the sauce.
Remove the skillet from the heat and mix in 60 g of the grated Parmesan cheese.
Divide the pasta among serving plates and garnish with the remaining 20 g of Parmesan and reserved fresh basil. Serve immediately.
