About This Recipe
This recipe is a celebration of simplicity and quality ingredients. The salami provides a robust, savory base, while fresh mozzarella adds a milky softness. Tomatoes offer acidity and sweetness, and the arugula salad—dressed with lemon and olive oil—cuts through the richness. The star is undoubtedly the homemade pesto, a classic Ligurian-style sauce made with basil, almonds, Parmesan, garlic, and olive oil. Unlike store-bought versions, this one bursts with fresh flavor. For the best results, use a good olive oil and high-quality ingredients. The sandwich needs at least an hour in the fridge, so plan accordingly—it’s worth the wait.
Ingredients
- 250 g salami, thinly sliced
- 300 g fresh mozzarella, sliced into rounds
- 100 g arugula (rocket)
- 3 ripe tomatoes, sliced
- 1 small red onion
- 3 tbsp extra-virgin olive oil
- 1 tbsp lemon juice
- Salt and freshly ground black pepper
For the pesto:
- 1 large bunch fresh basil (about 50 g leaves)
- 100 g grated Parmesan or Pecorino cheese
- 50 g almonds (or pine nuts)
- 1 garlic clove
- 6 tbsp extra-virgin olive oil
- 1 tsp grated lemon zest
- 1 tbsp lemon juice
- Salt to taste
You’ll also need a dense rustic bread (sourdough or country loaf), sliced 1.5 cm thick. A good convection oven can toast the bread lightly if desired, but it’s not necessary.
Step-by-Step Instructions
Step 1: Make the Pesto
Pull the basil leaves from the stems. Roughly chop the almonds and garlic. Combine basil, almonds, garlic, grated cheese, lemon zest, lemon juice, and olive oil in the bowl of a food processor. Add a pinch of salt. Pulse until smooth and creamy, scraping down the sides as needed. If you prefer a chunkier texture, pulse less. A high-powered food processor works beautifully here.
Step 2: Prepare the Arugula Salad
Peel the red onion and slice it into very thin rings. In a medium bowl, combine the onion slices with the arugula. Drizzle with 3 tablespoons of olive oil and 1 tablespoon of lemon juice. Season with salt and pepper, then toss gently to coat. Let it sit while you assemble the other components.
Step 3: Assemble the Sandwiches
Slice the bread into pieces at least 1.5 cm thick. Spread a generous layer of pesto on each slice. Slice the mozzarella and tomatoes into rounds. On half of the bread slices, layer salami, mozzarella, tomato slices, and a handful of the arugula salad. Top with the remaining bread slices. Press down firmly so the ingredients adhere. Wrap each sandwich tightly in plastic wrap and refrigerate for at least 1 hour (overnight is even better). The refrigerator works its magic, allowing the flavors to meld.
Tips for the Perfect Sandwich
- Bread choice: Use a sturdy rustic loaf that won’t get soggy. Sourdough, ciabatta, or pain de campagne work well.
- Pesto consistency: For a smoother pesto, use a immersion blender. For a chunkier texture, pulse in a food processor.
- Chilling time: At least one hour is essential. If you can, let the sandwiches rest overnight for the best flavor penetration.
- Serving: Cut the sandwiches in half on the diagonal for a beautiful presentation. They’re perfect for picnics, lunchboxes, or as a party snack.
- Moisture control: Pat the mozzarella and tomato slices dry with paper towels to prevent the bread from becoming too wet.
Variations
This sandwich is endlessly adaptable. Swap the salami for prosciutto or spicy capicola. Use provolone instead of mozzarella for a sharper edge. Add roasted red peppers or grilled zucchini for extra vegetables. For a vegan version, replace the cheese with plant-based alternatives and use nutritional yeast in the pesto. You can also try different nuts in the pesto—walnuts or cashews work wonderfully. Looking for more sandwich inspiration?

FAQ
Can I make this sandwich gluten-free?
Absolutely. Use your favorite gluten-free rustic bread. Just note that gluten-free breads can be more fragile, so handle with care when pressing and wrapping.
How long will this sandwich keep in the refrigerator?
Properly wrapped, the sandwich will stay fresh for up to 24 hours. After that, the bread may start to soften. It’s best enjoyed within 12 hours of assembly.
Can I use store-bought pesto instead?
Yes, but homemade pesto is far superior. If you’re in a pinch, choose a high-quality refrigerated pesto. For a quick fix, a pressure cooker won’t help here, but a blender will.
What kind of salami is best?
A dry-cured Italian salami like Genoa or Soppressata works beautifully. Avoid pre-sliced packages that are too thin; ask for thick slices at the deli counter for the best texture.
Can I toast the bread first?
Lightly toasting the bread adds a pleasant crunch. Just be sure to let it cool completely before assembling, or the cheese will melt prematurely. A non-toxic air fryer can do this quickly.
Conclusion
This hearty salami sandwich is more than a meal—it’s a testament to how simple, quality ingredients can create something extraordinary. The homemade pesto, the creamy mozzarella, the peppery arugula, all cradled in rustic bread and chilled to perfection, make every bite memorable. Whether you’re packing it for a picnic, serving it at a gathering, or simply treating yourself, this recipe delivers.
