Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package instructions until al dente.

Drain the pasta in a colander and set aside, reserving a cup of pasta water.

In a skillet, heat the olive oil over medium heat. Add the minced garlic and sauté until fragrant, about 1 minute.

Add the crushed tomatoes, oregano, salt, and pepper. Simmer for 15 minutes, stirring occasionally.

Add the cooked pasta to the sauce, tossing to coat. If the sauce is too thick, add reserved pasta water as needed.

Serve hot, topped with grated Parmesan cheese and fresh basil.
