Tools Needed to Make Pesto
- Food processor or blender – For quick, uniform blending.

Step-by-Step Guide to Making Pesto from Scratch
1. Prepare Your Ingredients
Start by gathering all your ingredients. Rinse the basil leaves thoroughly and pat them dry. Peel the garlic cloves. If you're using nuts other than pine nuts, lightly toast them in a dry skillet over medium heat for enhanced flavor, then let them cool.
2. Measure the Ingredients
For a standard batch, you might need:
- 2 cups of fresh basil leaves
- 2-3 garlic cloves
- 1/3 cup of pine nuts (or your preferred nuts)
- 1/2 cup of grated Parmesan cheese
- 1/2 cup of extra virgin olive oil
- Salt and freshly ground black pepper to taste
3. Blend the Basil and Nuts
Place the basil leaves and nuts into the food processor. Pulse a few times until roughly chopped. This step helps to evenly incorporate the ingredients and releases their flavors.
4. Add Garlic and Cheese
Add the peeled garlic cloves and grated Parmesan cheese to the mixture. Pulse again until the ingredients are finely combined. Be careful not to overprocess at this stage; you want a coarse, pesto-like consistency.
5. Incorporate Olive Oil
Slowly pour in the olive oil while the processor is running. This emulsification process creates a smooth, glossy sauce. Stop occasionally to scrape down the sides to ensure all ingredients are blended evenly.
6. Season and Adjust
Finally, taste your pesto and adjust seasoning with salt, pepper, or a splash of lemon juice if desired. If the pesto is too thick, add a little more olive oil to reach your preferred consistency.
Tips for Perfect Homemade Pesto
- Use fresh, high-quality ingredients: The flavor of your pesto depends heavily on the freshness of basil and quality of cheese and nuts.
- Don’t overprocess: A coarse texture is traditional and desirable; over-blending can turn it into a paste.
- Adjust the oil: Start with less oil and add more if needed to achieve desired consistency.
- Salt conservatively: You can always add more salt later, but it’s hard to fix an overly salty pesto.
- Experiment with nuts and herbs: Variations like arugula, spinach, or walnuts can create unique flavors.
Storing and Preserving Homemade Pesto
Refrigeration
Transfer your pesto into an airtight container and cover the surface with a thin layer of olive oil. Store in the fridge for up to a week. The oil helps prevent oxidation, keeping the pesto vibrant.
Freezing
For longer storage, freeze pesto in small portions using ice cube trays or silicone molds. Once frozen, transfer the cubes into a freezer-safe bag or container. This method allows you to enjoy fresh pesto whenever needed, with a shelf life of up to 6 months.
Serving Ideas for Homemade Pesto

- Spread on sandwiches or wraps for added flavor.
- Use as a dip for vegetables or breadsticks.
- Swirl into soups for an herbal kick.
- Top grilled chicken, fish, or roasted vegetables.
