In a large pot, cook the oil and garlic over medium-high heat until fragrant, about 30 seconds.
Stir in the crushed tomatoes, tomato paste, salt, pepper, and basil.
Cook the sauce over medium-high heat, stirring occasionally, until it starts to bubble. Cover, reduce the heat to low, and simmer for 45 minutes to 1 hour. (The longer it simmers, the better it tastes.)
