Recipe Instructions

1. Toast the walnuts in a dry pan over medium heat for 2-3 minutes, stirring occasionally, until fragrant. Let them cool slightly.

2. In a food processor or blender, combine the toasted walnuts, basil leaves, garlic, Parmesan cheese, lemon juice, salt, and pepper. Pulse until finely chopped.

3. With the processor running, slowly drizzle in the olive oil until the pesto reaches a smooth but slightly chunky consistency. Taste and adjust seasoning with more salt, pepper, or lemon juice as needed.

4. Season the chicken breasts with salt and pepper. Grill or pan-sear them over medium-high heat for 5-6 minutes per side, or until the internal temperature reaches 165°F (74°C). Let the chicken rest for a couple of minutes before shredding.

5. Mix the shredded chicken with the pesto.

6. Heat a skillet over medium heat and melt 1 tablespoon of butter (or use olive oil) in the pan. Slice the baguette in half and toast until golden and crispy, about 2-3 minutes per side.

7. Fill the toasted baguette slices with the chicken-pesto mixture, then add fresh mozzarella, tomatoes, and arugula.

8. Cut the sandwich in half and serve immediately.

Top Tips

• Toast the walnuts: Don’t skip this step! Toasting the walnuts for just a couple of minutes brings out their natural oils and enhances their flavor, making the pesto even more delicious.

• Adjust the pesto’s consistency: If you prefer a smoother pesto, add more olive oil; for a chunkier texture, use less. Play around until it’s just how you like it!

• Rest the chicken: Let the chicken rest for a few minutes after cooking before shredding. This helps keep it juicy and easier to pull apart.

• Toast the bread for extra crunch: Toast the sourdough baguette until golden and crispy. It adds texture and holds up better against the pesto and melted cheese.

• Add extra flavor with toppings: Feel free to get creative with your sandwich toppings! Roasted red peppers, avocado, or even a drizzle of balsamic glaze could make it even tastier.

• Use fresh mozzarella: Fresh mozzarella works best in this recipe for its creamy texture and meltability. Be sure to slice it thinly for the perfect bite!

• Season the sandwich: Don’t forget to season the chicken and veggies with salt and pepper as you assemble. A little extra seasoning can make all the difference.

• Make ahead the pesto: You can prepare the walnut pesto in advance and store it in the fridge for a few days. It’ll save you time when putting the sandwich together!

• With a refreshing iced tea: This sandwich pairs wonderfully with a cold, refreshing iced tea or lemonade, especially on a hot day.

• Toast the bread for added crunch: If you love extra crunch, give your sandwich a quick toast in a pan before serving, it makes the whole experience even more satisfying.

• For a fun twist, turn it into a panini: Grill the sandwich in a panini press for those crispy, golden edges and gooey melted cheese.

• Add a fried egg: For an extra layer of richness, top your sandwich with a fried egg. The runny yolk is the perfect addition!

Absolutely! You can prepare the walnut pesto in advance and store it in an airtight container in the fridge for up to 3 days. Just give it a stir before using it in the sandwich.
