Store leftovers in an airtight container in the refrigerator for up to 3 days. When cooking pasta, ensure it is well-drained and tossed with sauce immediately to prevent sticking. If garlic begins to brown, reduce the heat to medium-low immediately to prevent burning and maintain a mellow flavor. If tomatoes are not bursting, slightly increase the heat while closely monitoring to keep the garlic from burning. For a more pronounced flavor, adjust salt and pepper more generously during cooking. If fresh ingredients are limited, consider using canned tomatoes or frozen beans as convenient alternatives without sacrificing taste. Reheat in a skillet with a splash of water to maintain moisture.
