Simple Tomato Sauce

While watching Kelsey's Essentials on the Cooking Channel I saw this recipe and made it immediately. The flavor combination is wonderful and when I invited friends over the smell made their mouths water.

Simple Tomato Sauce
1/4 cup extra-virgin olive oil
1 medium yellow onion, diced
3 garlic cloves, peeled and sliced
3 tablespoons chopped fresh basil or 1 tablespoon dried basil
2 (28-ounce) cans diced tomatoes
Salt and freshly ground black pepper

To make Simple Tomato Sauce:
In a large saucepan, heat the olive oil over medium heat. Add the onion, and garlic and cook until soft and golden brown. Add the basil and cook for an additional 3 to 5 minutes. Add the canned tomatoes with their juices and bring to a boil, stirring often. Lower the heat and simmer for 15 to 20 minutes, until the sauce has thickened. With a potato masher, break up the tomatoes to achieve a sauce-like consistency.
Season with salt and freshly ground black pepper and serve.
