How to Store or Freeze This Recipe
To store your lemony basil pesto, transfer it to an airtight container. Make sure to press a piece of plastic wrap directly onto the surface of the pesto to prevent air exposure, which can cause discoloration.
For longer storage, consider freezing the pesto. Spoon it into an ice cube tray, filling each compartment. Once frozen, transfer the pesto cubes to a resealable plastic bag or another airtight container. This method allows you to thaw only the amount you need.
When freezing, you can also add a thin layer of olive oil on top of the pesto in the container. This extra layer of oil helps to seal in the freshness and prevent freezer burn.
Label your containers or bags with the date of preparation. Pesto can be stored in the freezer for up to three months without losing its vibrant flavor.
To thaw, simply place the desired amount of pesto in the refrigerator overnight. If you're in a hurry, you can also thaw it at room temperature for a few hours or use the defrost setting on your microwave.
Once thawed, give the pesto a good stir to reincorporate any separated olive oil. Adjust the seasoning if necessary, as freezing can sometimes dull the flavors slightly.
For a quick and easy meal, toss the thawed pesto with freshly cooked pasta, spread it on a sandwich, or use it as a flavorful topping for grilled meats and vegetables.
How to Reheat Leftovers
For a quick and easy method, place the pesto in a microwave-safe bowl. Cover it loosely with a microwave-safe lid or plastic wrap. Heat on medium power for 20-30 seconds, stirring halfway through to ensure even heating. Be careful not to overheat, as this can cause the basil to lose its vibrant color and fresh flavor.
If you prefer a stovetop method, transfer the pesto to a small saucepan. Warm it over low heat, stirring frequently. This gentle method helps maintain the integrity of the olive oil and parmesan cheese. Add a splash of lemon juice or a drizzle of olive oil if the pesto seems too thick.
For a more integrated approach, toss the pesto with freshly cooked pasta directly in the pot. The residual heat from the pasta will warm the pesto perfectly. If needed, add a bit of the pasta cooking water to achieve the desired consistency.
To reheat pesto for a sandwich or wrap, spread it on the bread or tortilla and then toast or grill the assembled sandwich or wrap. This method ensures the pesto warms up without direct exposure to high heat, preserving its fresh taste.
If using the pesto as a dip or spread, allow it to come to room temperature naturally. This can be done by leaving it out on the counter for about 30 minutes before serving. This method avoids any risk of overheating and maintains the pesto's bright, fresh flavors.

Airtight container: Necessary for storing the pesto in the refrigerator to keep it fresh for up to a week.
How to Save Time on Making This Recipe
Pre-measure ingredients: Measure and prepare all ingredients before starting. This will streamline the process and ensure you have everything ready.
Use pre-toasted nuts: Buy pre-toasted pine nuts to save time on toasting them yourself.
Minced garlic: Use pre-minced garlic from a jar to cut down on prep time.
