Cook vegetables gently without browning to build sweetness. Simmer low and slow for at least 2½ hours for best flavor. Stir occasionally to prevent sticking. Let the sauce rest 15–20 minutes before serving. For variation, add a splash of milk for creaminess, mushrooms for depth, or red pepper flakes for heat. Sauce can be refrigerated up to 4 days or frozen up to 3 months.
