Use a spoon to fill all the compartments in the ice cube tray with fresh homemade pesto.
Drizzle a little bit of olive oil on top of each compartment. This is done to make sure the pesto doesn’t turn dark.
Wrap the whole ice cube tray with plastic wrap. Press it gently on each cube compartment to leave as little room for air as possible.
Place the tray in the freezer overnight until the pesto has completely frozen.
Remove the tray from the freezer, hold it under cold water for a couple of seconds until the pesto cubes pop out easily.
Get a freezer bag and dump the pesto cubes inside. Store the bags in the freezer for as long as 6 months.
Notes
Blanch the basil leaves before throwing them into your food processor. This will help them retain their beautiful green color.
To use frozen pesto, you need to let it thaw before adding it to a dish. Put it in the refrigerator for a while until it’s ready to use or pop it in the microwave on the defrost setting.
If you wish to freeze pesto to use it as a pizza sauce, then you should pour it into mason jars and store them in the freezer.
