Pesto, the quintessential Italian sauce, has become a staple in many cuisines around the world. Made from basil, garlic, pine nuts, Parmesan, and olive oil, pesto adds a rich and vibrant flavor to various dishes, from pasta and pizza to soups and salads. While fresh homemade pesto is always preferred, jarred pesto is a convenient alternative that can be just as delicious when heated properly. In this article, we will explore the best ways to heat jarred pesto, its benefits, and some creative recipe ideas to get you started.
Understanding Jarred Pesto
Before we dive into the heating process, it’s essential to understand the characteristics of jarred pesto. Unlike fresh pesto, which is made from raw ingredients, jarred pesto is a processed product that has undergone heat treatment to extend its shelf life. This heat treatment can affect the flavor and texture of the pesto, making it slightly different from its fresh counterpart.
The Science Behind Heating Pesto
Heating pesto can be a bit tricky, as it can quickly become bitter or separate if not done correctly. This is because pesto contains a high amount of oil, which can cause it to break down when heated. However, with the right techniques, you can heat jarred pesto without compromising its flavor and texture.
The Role of Emulsifiers
Emulsifiers play a crucial role in maintaining the stability of pesto when heated. Emulsifiers are ingredients that help combine oil and water-based ingredients, preventing them from separating. In the case of pesto, emulsifiers like lecithin or xanthan gum are often added to the jarred product to ensure it remains smooth and creamy when heated.
Methods for Heating Jarred Pesto
Now that we understand the science behind heating pesto, let’s explore the best methods for warming up jarred pesto.
Method 1: Microwave Heating
Microwaving is a quick and easy way to heat jarred pesto. Here’s a step-by-step guide:
- Place the jarred pesto in the microwave for 10-15 seconds.
- Remove the pesto from the microwave and stir well.
- Check the temperature and repeat the process if necessary.
Important: Be cautious when microwaving pesto, as it can quickly become too hot and separate.
Method 2: Stovetop Heating
Stovetop heating is a more gentle way to warm up jarred pesto. Here’s how:
- Place the jarred pesto in a saucepan over low heat.
- Stir the pesto constantly to prevent it from burning or separating.
- Heat the pesto for about 2-3 minutes or until it reaches your desired temperature.
Method 3: Double Boiler Heating
Double boiler heating is a more sophisticated method that ensures gentle and even heating. Here’s how:
- Fill a saucepan with water and bring it to a simmer.
- Place the jarred pesto in a heatproof bowl or saucepan over the simmering water.
- Stir the pesto occasionally until it reaches your desired temperature.
Benefits of Heating Jarred Pesto
Heating jarred pesto can bring out its flavors and aromas, making it a more enjoyable and satisfying experience. Here are some benefits of heating jarred pesto:
- Enhanced flavor: Heating pesto can release its natural oils and flavors, making it more aromatic and delicious.
- Improved texture: Heating pesto can help to emulsify the ingredients, creating a smoother and creamier texture.
- Increased versatility: Heated pesto can be used as a sauce for pasta, pizza, or as a dip for vegetables.

What is the best way to heat jarred pesto without losing its flavor?
Heating jarred pesto can be a bit tricky, but there are a few methods that can help preserve its flavor. One of the best ways is to heat it gently over low heat, whisking constantly. This will help prevent the basil from losing its vibrant green color and the garlic from becoming bitter. You can also add a little bit of oil or cream to the pesto to help it heat more evenly and prevent it from separating.
Another option is to heat the pesto in the microwave, but be careful not to overheat it. Start with short intervals of 10-15 seconds and check the pesto until it’s warmed through. Stir well after each interval to ensure even heating. It’s also important to note that heating pesto can cause it to lose some of its potency, so it’s best to use it immediately after heating.
Can I heat jarred pesto directly in the jar?
It’s generally not recommended to heat jarred pesto directly in the jar. The jar may not be designed for high temperatures, and the pesto may not heat evenly. Additionally, the jar may become too hot to handle, and the pesto may splatter or spill when you try to remove it. Instead, transfer the pesto to a saucepan or microwave-safe bowl before heating.
If you do choose to heat the pesto in the jar, make sure to check the manufacturer’s instructions first. Some jars may be specifically designed for microwave heating, but it’s still important to be cautious and heat the pesto in short intervals, checking on it frequently to avoid overheating.
How long does it take to heat jarred pesto?
The time it takes to heat jarred pesto will depend on the method you choose and the amount of pesto you’re heating. If you’re heating it on the stovetop, it can take anywhere from 2-5 minutes, depending on the heat level and the amount of pesto. If you’re heating it in the microwave, it can take anywhere from 10-30 seconds, depending on the power level of your microwave and the amount of pesto.
It’s also important to note that you don’t need to heat the pesto to a boiling point. Simply warming it through is enough to bring out the flavors and aromas. Stir the pesto frequently as it heats to ensure even warming and to prevent it from separating.
Can I add other ingredients to jarred pesto while heating it?
Yes, you can add other ingredients to jarred pesto while heating it to enhance the flavor and texture. Some popular additions include grated Parmesan cheese, chopped sun-dried tomatoes, and cooked chicken or shrimp. You can also add some heavy cream or half-and-half to give the pesto a creamy texture.
When adding ingredients to the pesto, it’s best to do so towards the end of the heating time. This will help prevent the ingredients from cooking too long and losing their flavor and texture. Stir well to combine and adjust the seasoning as needed.
Is it safe to heat jarred pesto that’s past its expiration date?
It’s generally not recommended to heat jarred pesto that’s past its expiration date. While the pesto may still be safe to eat, its quality and flavor may have degraded over time. Heating it can cause the flavors to become bitter and unpleasant, and it may also cause the pesto to separate or become too oily.
If you’re unsure whether the pesto is still good, check the expiration date and look for any signs of spoilage, such as mold or an off smell. If in doubt, it’s best to err on the side of caution and discard the pesto.
Can I heat jarred pesto ahead of time and refrigerate or freeze it?
Yes, you can heat jarred pesto ahead of time and refrigerate or freeze it for later use. In fact, heating the pesto can help to preserve it and extend its shelf life. Once heated, let the pesto cool to room temperature, then refrigerate or freeze it in an airtight container.
When reheating the pesto, make sure to heat it gently over low heat, whisking constantly, to prevent it from separating or becoming too oily. You can also reheat it in the microwave, but be careful not to overheat it.
How do I store heated jarred pesto?
Once you’ve heated jarred pesto, it’s best to store it in an airtight container in the refrigerator. Let the pesto cool to room temperature, then transfer it to a container with a tight-fitting lid. The pesto will typically keep for 3-5 days in the refrigerator.
If you don’t plan to use the pesto within a few days, you can also freeze it. Transfer the cooled pesto to an airtight container or freezer bag, making sure to press out as much air as possible before sealing. Frozen pesto will typically keep for 6-9 months. When you’re ready to use it, simply thaw it in the refrigerator or reheat it gently over low heat.
