How Long Will Fresh Pesto Keep?
Pesto, a flavorful sauce made from basil, garlic, pine nuts, olive oil, and Parmesan cheese, is a staple in Italian cuisine. Whether you’re using it as a topping for pasta, a dip for bread, or a spread for sandwiches, the fresh, aromatic taste of pesto is unmatched. However, one question that often arises is: how long will fresh pesto keep? Understanding the shelf life of pesto can help you make the most of this delicious sauce and prevent waste.
Fresh pesto has a relatively short shelf life compared to commercially produced versions. Typically, when stored properly, homemade pesto can last in the refrigerator for about 7-10 days. To extend its longevity, it’s essential to store it correctly. Here’s how:
1. Transfer pesto to an airtight container: Once you’ve made your pesto, transfer it to an airtight container to prevent air from entering and causing oxidation, which can lead to separation and spoilage.
2. Use a spatula to remove as much air as possible: Before sealing the container, use a spatula to press down on the pesto, pushing out as much air as you can. This will help preserve the sauce’s quality.
3. Cover the container with a lid: Ensure the lid is tightly sealed to maintain the freshness of the pesto. A plastic wrap or a lid with a tight seal will work well.
4. Store in the refrigerator: Keep the pesto in the refrigerator at a temperature of 35-40°F (1.7-4.4°C). This cool environment will slow down the growth of bacteria and extend the shelf life.
5. Consume within 7-10 days: While pesto can last up to two weeks in the refrigerator, it’s best to consume it within 7-10 days for the best flavor and quality.
If you find that your pesto has lasted longer than the recommended shelf life, here are a few signs to look out for that indicate it may be time to discard it:
– Unusual odor: If your pesto has an off smell, it’s best to discard it, as this could be a sign of spoilage.
– Discoloration: Fresh pesto should have a vibrant green color. If you notice any darkening or separation of colors, it’s best to throw it away.
– Watery texture: If the pesto has become watery or has separated, it’s likely that the quality has deteriorated, and it’s no longer suitable for consumption.
Remember, while it’s important to follow proper storage and usage guidelines to extend the shelf life of fresh pesto, the best way to enjoy its full flavor is to consume it within the recommended timeframe. By doing so, you’ll be able to savor the rich, aromatic taste of pesto in all its glory.
