- 1/2 cup grated Parmesan cheese
- 1/2 cup extra virgin olive oil
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
Ingredient Notes and Substitutions

How to Make Walnut Pesto
Start by washing the fresh basil leaves and patting them dry. This helps remove any dirt and ensures your pesto is fresh.
Lightly toast the walnuts in a skillet for 5 minutes over medium heat. This intensifies their flavor, giving your pesto a deeper nutty taste.
Add the basil leaves and garlic cloves to the food processor. This creates a fragrant base for your pesto.
Incorporate the toasted walnuts into the mix. Pulse a few times until coarsely chopped.
Mix in the grated Parmesan cheese and start drizzling in the olive oil. This creates a creamy consistency.
Add salt and black pepper to taste. These will enhance the flavors of the other ingredients.
Process the mixture until it reaches your desired consistency. A few small chunks add texture, but aim for a smooth finish.
Finally, taste your pesto and adjust salt, pepper, or garlic according to your preference. This step personalizes the final flavor.

Pro Tip: Always taste and adjust seasonings before serving — every ingredient has its own strength.
Tips for the Best Walnut Pesto
- Use fresh basil for maximum flavor; it’s the essential herb in pesto.
- Toast walnuts lightly to enhance their nutty flavor; keep an eye on them to prevent burning.
- Adjust garlic to your personal preference; more garlic makes it more robust.
- Store in an airtight container for longer freshness; a layer of olive oil on top can help reduce oxidation.
- Experiment with different cheese or nuts for unique flavors; each variation brings a new twist.
Common Mistakes to Avoid
- Skipping the toasting step can lead to bland pesto; toasting boosts richness.
- Overblending can make the pesto watery; aim for a textured consistency.
- Ignoring salt can result in a flat flavor; seasoning is key to balancing flavors.
- Using wilted basil can diminish the flavor; always use fresh herbs for vibrancy.

Storage and Reheating
Refrigerator
Store pesto in an airtight container in the fridge. It can last up to a week if stored properly.

Freezer
Walnut pesto freezes beautifully. Portion it into ice cube trays for easy use.
