How Long Does Romesco Sauce Last?
Keep your roasted pepper spread fresh and flavorful in the fridge.
Romesco sauce lasts about 2 weeks in the refrigerator when stored in an airtight container.
Romesco sauce is a vibrant, textured condiment made from roasted red peppers, tomatoes, garlic, and toasted nuts. Because it contains fresh components like roasted vegetables and often oil-based bases, maintaining its quality depends on proper cooling and containment. While the acidity from tomatoes can help preserve it, moisture and oxidation are the primary enemies of flavor. Storing your romesco sauce in a sealed glass jar prevents it from absorbing other flavors while keeping the texture smooth and the colors bright for several weeks.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
