1medium onion, peeled and sliced into large quarters (root base attached)
4cloves garlic, peeled and smashed
128-ounce can unsalted San Marzano whole tomatoes
large sprig fresh basil, plus more to garnish
1 1/2teaspoonskosher salt, or to taste
1generous pinch red pepper flakes
generous pinch sugar, optional
Instructions
Crush the tomatoes by hand or by sticking kitchen shears in the can and snipping until the whole tomatoes are broken up into chunks. Set aside.
Heat the olive oil with the onion quarters over medium heat in a large skillet.
When the onion starts to gently sizzle, add the garlic, tomatoes, salt, red pepper flakes, and basil. Swish about a 1/2 cup of water in the empty tomato can to get the rest of the tomatoes out, and add the tomato water to the skillet. Stir gently.
When the tomatoes come to a boil, reduce heat to a low simmer and cook for 15 to 20 minutes, stirring frequently. Taste for seasoning. Depending on the acidity of the tomatoes, you may want to add a pinch or two of sugar, and maybe a little more salt. Remove onion pieces -- which should be falling apart -- before serving, but do not discard. They are delicious on crusty bread, or on their own.
