Last of the Summer Basil: How to Make It Last All Winter
Don’t Let Your Basil Go to Waste
As the cooler air begins to settle in and winter approaches, many gardens start to slow down. But if you’ve still got basil thriving in the autumn sunshine, now is the perfect time to make the most of it.
Basil is one of the most versatile and flavourful herbs you can grow—fresh, fragrant, and perfect for elevating everyday meals. Rather than letting those last vibrant leaves go to waste, you can turn them into something truly special that lasts well beyond the season.
One of the easiest and most rewarding ways to preserve basil is by making homemade pesto—a simple, fresh recipe that brings a taste of summer into the colder months.
Basil & Mint Pesto Recipe (Quick & Easy)
Adding mint to traditional pesto gives it a refreshing lift—enhancing the basil without overpowering it.
Ingredients
6 cloves garlic, peeled
1 cup loosely packed fresh mint leaves
2 cups loosely packed fresh basil leaves
300ml olive oil
1 teaspoon salt
1 cup pine nuts (lightly toasted and cooled)
½ cup finely grated parmesan
½ cup finely sliced chives (optional)
Method
Add garlic, basil, mint, olive oil, salt, and pine nuts to a food processor.
Blend into a coarse paste (avoid over-processing).
Transfer to a bowl and stir in parmesan and chives.
Adjust consistency with extra olive oil if needed—aim for slightly chunky rather than smooth.
Ingredient Alternatives
Nut-free: Use toasted sunflower, pumpkin, or sesame seeds
Budget-friendly: Swap pine nuts for walnuts
Other options: Almonds or cashews work well
