What is Pesto?
Pesto is a traditional Italian sauce made with fresh basil, garlic, pine nuts, Parmesan cheese, and olive oil. The name “pesto” comes from the Italian word “pestare,” meaning to crush or pound, which describes the traditional process of making the sauce using a mortar and pestle.
Pesto originated in Genoa, Italy, and has become a popular sauce worldwide due to its delicious and versatile nature. It can be used as a spread, dip, or sauce for pasta, meats, and vegetables, making it a staple in many kitchens.

Shelf life of Pesto
If you’ve ever wondered how long your homemade or store-bought pesto can last in the refrigerator, you’re not alone. The shelf life of pesto can vary depending on several factors, including the ingredients used, storage conditions, and the type of pesto.
- Homemade pesto typically lasts for 5-7 days in the refrigerator. This is assuming that it’s stored in an airtight container and kept in the coldest part of the fridge (usually the back shelf).
- Store-bought pesto can last for up to 2 weeks or more if it’s unopened and stored in the refrigerator. However, once it’s opened, the shelf life decreases significantly.
- Freezing pesto can extend its shelf life to several months. By storing it in the freezer, you can use it whenever you need it, without worrying about it going bad quickly. Simply transfer it to the fridge to thaw it out before you use it.
It’s important to note that the shelf life of pesto can be affected by several factors. These include:
1. Exposure to air: When pesto is exposed to air, it can quickly go bad. Therefore, it’s important to store it in an airtight container to keep it fresh for as long as possible.
2. Contamination: If you use a dirty spoon or knife to scoop out pesto, bacteria can be introduced to the jar and cause it to spoil more quickly. Therefore, it’s important to use clean utensils when handling pesto.
3. Quality of ingredients: The quality of the ingredients used to make the pesto can also impact how long it lasts. For example, if you use old or wilted basil leaves, the pesto may not last as long as if you use fresh, high-quality basil.
How to tell if pesto has gone bad?
If you’re unsure whether your pesto has gone bad or not, there are a few signs to look out for. These include:
- Foul smell: If your pesto smells off or foul, it’s likely gone bad.
- Mold: If you notice any mold on the surface of the pesto, it’s best to throw it away immediately.
- Off taste: If the pesto tastes different than usual or has a strange aftertaste, it may have gone bad.
By following proper storage procedures, you can extend the shelf life of your pesto and keep it fresh for as long as possible.
| Type of Pesto | Shelf Life |
|---|---|
| Homemade Pesto | 5-7 days |
| Store-Bought (Unopened) | Up to 2 weeks or more |
| Store-Bought (Opened) | 5-7 days |
| Frozen Pesto | Several months |
Remember to always use your sight and smell senses to check if the pesto has gone bad even if it’s still within the shelf life period.
Storage conditions for Pesto
Storing pesto properly is essential to ensure its longevity and prevent spoilage. Here are some storage conditions to follow:
- Refrigeration: Pesto should always be kept in the refrigerator. This helps slow down the oxidation process and prevents the growth of bacteria and mold.
- Airtight container: Store pesto in an airtight container to prevent oxidation and contamination. Glass jars or plastic containers with tight-fitting lids work best.
- Avoid exposure to air: Pesto should not be left out for long periods. Once opened, consume within a few days to prevent exposure to air.
These storage conditions will help your pesto stay fresh for longer, but it’s essential to understand the shelf life of pesto as well. Here’s a table that outlines the different types of pesto and their storage duration.
| Type of Pesto | Refrigerator Storage Duration |
|---|---|
| Homemade basil pesto | 1 week |
| Commercially prepared pesto (unopened) | Up to 6 months |
| Commercially prepared pesto (opened) | 1-2 weeks |
By following these storage conditions, you can ensure that your pesto stays fresh and delicious for as long as possible.
How to Tell If Pesto Has Gone Bad
Pesto is a delicious blend of fresh herbs, nuts, and olive oil that adds flavor and vibrancy to many dishes. However, like all foods, pesto can spoil over time. Knowing how to tell if your pesto has gone bad can help you avoid food poisoning and ensure that your dishes taste their best.
- Check the expiration date: One of the easiest ways to tell if your pesto has gone bad is to check the expiration date. Most commercially made pesto will have a “best by” date printed on the label. If the date has passed, it’s time to toss the pesto.
- Spoilage signs: Look for signs of spoilage, like mold, discoloration, or an odor that seems off. If your pesto looks or smells funny, it’s best to err on the side of caution and throw it out.
- Texture changes: Pesto that has gone bad may also have a different consistency. If it seems thicker or grainier than usual, it’s possible that it has started to spoil.
It’s important to note that homemade pesto may have a shorter shelf life than store-bought varieties, as it does not have the same preservatives. It’s best to consume homemade pesto within a few days of making it.
If you’re unsure whether your pesto has gone bad or not, it’s better to be safe than sorry. Tossing it out and making a fresh batch is a small price to pay for your health and safety.
Below is a table that shows the approximate shelf life of different types of pesto:
| Type of Pesto | Shelf Life |
|---|---|
| Store-bought, unopened | 6-12 months |
| Store-bought, opened | 1-2 weeks |
| Homemade, refrigerated | 3-5 days |
| Homemade, frozen | 6 months to a year |
By following these guidelines and using your senses to determine if your pesto has gone bad, you can enjoy this delicious condiment without any worries.
Can Pesto be frozen?
If you have a big batch of pesto and you don’t want it to spoil, freezing is the best option. You can freeze pesto for up to six months, and it will still retain its flavor and texture. However, it’s essential to know that freezing pesto will slightly change its consistency, making it less creamy than fresh pesto.
- The best way to freeze pesto is to spoon it into an ice cube tray and place it in the freezer. Once the pesto bits are frozen, remove them from the tray and place them in a freezer-safe container. This method allows you to save time when you need to use pesto, as you can take out just the amount you require.
- Another alternative is to freeze pesto in a glass jar or plastic container with a tight-fitting lid. However, make sure you do not fill the container to the top, as pesto expands as it freezes.
- When thawing pesto, always do it gradually, by moving it from the freezer to the fridge. It’s also important to note that pesto should never be thawed, then refrozen.
Freezing pesto can save you money and time. It’s an excellent way to preserve the delicious taste of pesto, even long after its expiration date.
