Step 1

In a medium saucepan over medium-high heat, heat oil until shimmering. Add garlic cloves and sauté until browned, stirring occasionally to prevent scorching, about 3 to 4 minutes. Remove garlic and discard.

Step 2

Stir in crushed tomatoes, diced tomatoes, sugar (if using), basil, oregano, and salt and pepper to taste (I like 1/2 teaspoon salt and 1/4 teaspoon pepper). Reduce heat to medium and simmer uncovered until flavors have blended, about 10 minutes.

Step 3

Keep warm over low-heat until serving time, or cool completely and store covered in the refrigerator.
