Why This Sandwich Stands Out

  • Gourmet Ingredients: Swaps basic white bread for herbed focaccia, and classic mayo for savory pesto mayonnaise.
  • Bold Flavors: Layered tastes—sweet tomato, peppery arugula, rich pesto, and sharp pickled onion.
  • Make-Ahead Components: Prepare the pickled onions and pesto mayo in advance for quick assembly.
  • Fresh and Satisfying: Crisp vegetables and tender ham ensure every bite is pleasing and balanced.

Ingredients

Gather these essentials for an authentic result. Each component contributes to the sandwich’s harmonious flavor:

For the Pickled Red Onion

  • 1 red onion, thinly sliced
  • 3/4 cup apple cider vinegar
  • 1 tablespoon kosher salt
  • 1 tablespoon sugar
  • 1 teaspoon coriander seeds, crushed

Flavor Note:

Pickled onions add a tangy crunch that brightens up the whole sandwich and contrast naturally with creamy pesto mayo and ham.

For the Pesto Mayonnaise

  • 1/2 cup mayonnaise
  • 1/4 cup pesto (homemade or store-bought)

Flavor Note:

Pesto’s herbal, garlicky notes blend with creamy mayo for a versatile condiment that instantly elevates the sandwich.

For the Sandwiches

  • 4 squares (5-inch) herbed focaccia, sliced horizontally
  • 4 thick slices ripe tomato
  • 1 lb honey ham, thinly sliced
  • 1 1/2 cups baby arugula

Using herbed focaccia gives the sandwich a Mediterranean flair; the honey ham lends smoky-sweetness, while arugula’s peppery bite is the perfect foil for rich flavors.

Step-by-Step Directions

Here’s how to prepare every delicious layer for maximum freshness and flavor.

Step 1: Pickle the Red Onion

  1. In a medium saucepan, combine red onion, vinegar, salt, sugar, and coriander seeds.
  2. Bring to a simmer over medium heat, stirring occasionally.
  3. Cook until onions soften and change color (about 2 minutes).
  4. Transfer to a heatproof bowl; press onions down so they’re submerged.
  5. Let cool to room temperature in the liquid (about 1 hour).
  • Use immediately or store refrigerated up to 5 days for a quick lunch upgrade.

Step 2: Make the Pesto Mayonnaise

  1. Mix mayonnaise and pesto in a small bowl until uniform.
  2. Refrigerate until ready to use; it keeps for several days.

This easy two-ingredient spread adds depth to deli sandwiches, grilled chicken, wraps, and even salads.

Step 3: Prepare the Focaccia

  1. Preheat oven to 400˚F (204˚C).
  2. Lay sliced focaccia cut-side up on a baking sheet.
  3. Bake until lightly toasted (8–10 minutes). Let cool.
  • Toasted focaccia resists sogginess and provides the needed structural integrity for stacked fillings.

Step 4: Assemble the Sandwiches

  1. Spread pesto mayo generously on the cut sides of the focaccia.
  2. Layer the bottom half with tomato slices, then add ham, arugula, and pickled red onion.
  3. Top with the other focaccia half; press gently.

The composition ensures each bite is balanced and bursting with flavor—the sweetness of ham, acidity of tomato, herbal richness of pesto, and brightness of pickled onion all shine through.

Serving Suggestions & Pairings

  • Picnic Ready: These sandwiches travel well and are ideal for picnics or packed lunches. Make all components ahead, and simply assemble at the last minute for freshest taste.
  • Side Dishes: Try a crunchy cabbage or watermelon feta salad, kettle-cooked chips, or marinated olives for a complete meal.
  • Drink Pairing: A sparkling water with lemon or chilled rosé complements the sandwich’s bright flavors.

Expert Tips & Variations

  • Herbed Focaccia: Use store-bought or homemade. Rosemary, thyme, or basil infuse each bite with extra flavor.
  • Pesto Swaps: Try sun-dried tomato pesto or arugula pesto for new flavor profiles.
  • Cheese Option: Add a slice of sharp provolone or creamy mozzarella for a richer sandwich (though the original is delightfully cheese-free).
  • Protein Variations: Substitute turkey, grilled chicken, or even prosciutto to suit your preferences.
  • Gluten Free: Swap for gluten-free focaccia or whole-grain bread slices.

Make-Ahead and Storage Instructions

  • Pickled Onions: Store in an airtight container in the refrigerator for up to five days.
  • Pesto Mayonnaise: Keeps chilled up to one week; stir before spreading.
  • Focaccia: Toast and cool in advance; wrap tightly to avoid drying out.
  • Do not fully assemble sandwiches more than a few hours ahead—store fillings separately to maintain fresh texture.

Why Arugula and Pesto Mayo Are a Perfect Match

Arugula brings a peppery, fresh snap that cuts through the richness of mayonnaise and ham, while pesto infuses classic Italian herb flavor. Together, they transform deli staples into something special—robust but balanced, with freshness in every layer. Even without cheese, the combination feels luxurious thanks to the creamy pesto drizzle and vibrant vegetables.

Frequently Asked Questions (FAQs)

Q: Can I substitute regular bread for focaccia?

A: Yes, but focaccia’s herby flavor and chewy texture add distinction. Ciabatta or hearty wheat bread are good alternatives.

Q: Is it necessary to pickle the onions?

A: Pickling gives a distinct brightness and crunch, but in a pinch, thinly sliced raw onion or quick pickled cucumbers also work.

Q: Can I make the sandwich vegetarian?

A: Replace ham with grilled rotisserie vegetables, roasted portobello, or thick mozzarella slices for a meatless version.

Q: How long do leftovers keep?

A: Prepared components last several days in the fridge (except assembled sandwiches, which are best eaten fresh for texture).

Q: What makes pesto mayo special?

A: The combination provides a complex, herbal condiment—ideal for not just sandwiches but as a dip for fries, drizzle for grilled meats, or binder in cold salads.

Recipe Variations and Popular Twists

  • Open-Faced: Use focaccia as a base for stacked fillings—serve as an appetizer or light lunch.
  • Mini Sandwiches: Slice focaccia smaller for hors d’oeuvres or party platters.
  • Bread Swaps: Try rye, sourdough, baguette, or slider buns for a fresh take.
  • Extra Crunch: Add thin radish or cucumber slices alongside arugula.
  • Spicy Kick: Blend a little sriracha into the pesto mayo or sprinkle red pepper flakes on arugula.

Perfect Occasions For This Sandwich

  • Lunches: A showstopper for office or school lunch—make ahead and assemble fresh.
  • Picnics: Portable ingredients and robust bread make it ideal for outdoor eating.
  • Brunch: Pair with fruit salads and sparkling beverages at daytime gatherings.
