Making your own pesto at home allows you to customize the ingredients, control the salt and oil content, and enjoy a truly fresh, flavorful condiment.

Understanding the Basics of Pesto
Before diving into the recipe, it's helpful to understand what makes pesto unique. Traditional pesto, known as pesto alla genovese, relies on a few key ingredients: fresh basil, garlic, pine nuts, Parmesan cheese, and olive oil. The ingredients are combined in a mortar and pestle or food processor to create a fragrant, emulsified sauce.
Homemade pesto is highly customizable. You can experiment with different nuts, herbs, or cheeses to create variations suited to your taste. However, sticking to the classic ingredients will give you that authentic flavor that’s both bright and savory.

Step-by-Step Guide to Making Homemade Pesto
Step 1: Prepare the Basil
- Rinse basil leaves gently under cold water.
- Pat dry thoroughly with paper towels or a clean cloth to prevent excess moisture.
- Remove any thick stems, keeping only tender leaves.
Step 2: Toast the Nuts (Optional)
- Place pine nuts in a dry skillet over medium heat.
- Toast for 2-3 minutes, stirring constantly until golden and fragrant.
- Allow to cool before use.
Step 3: Toast the Garlic (Optional)
- For a milder, mellow garlic flavor, lightly toast garlic cloves in the skillet until fragrant.
- This step is optional but adds depth.
Step 4: Combine Ingredients
You can choose between traditional mortar and pestle or modern food processor:
- Using a mortar and pestle: Place garlic and a pinch of salt in the mortar. Pound until smooth. Add basil leaves gradually, crushing and turning until you get a fragrant paste. Mix in toasted pine nuts, then cheese. Slowly drizzle in olive oil while continuing to grind until you reach your desired consistency.
- Using a food processor: Combine basil, garlic, toasted pine nuts, and grated cheese in the bowl. Pulse several times to chop evenly. With the processor running, slowly pour in olive oil until the mixture emulsifies into a smooth sauce. Stop and scrape down the sides as needed.
Step 5: Adjust Seasonings
- Taste your pesto and add salt as needed.
- For extra brightness, a squeeze of lemon juice can be added at this stage.
Step 6: Store Properly
- Transfer the pesto to a clean jar or airtight container.
- Cover the surface with a thin layer of olive oil to prevent oxidation.
- Store in the refrigerator for up to a week, or freeze in small portions for longer storage.
