Halloumi and Pesto Sandwich
This is the definitive "gastro-café" lunch brought right into your kitchen. It’s built around thick, salty slabs of halloumi cheese pan-seared until golden and "squeaky," paired with a vibrant, garlicky herb pesto. Layered on toasted sourdough with sun-dried tomatoes and peppery arugula, it hits every flavor note—salty, tangy, and fresh. It’s an indulgent vegetarian powerhouse that feels gourmet but takes less than 15 minutes to throw together.
Ingredients
- 250 g Halloumi Cheese Sliced into 1cm thick slabs; pat dry before frying.
- 4 Slices Sourdough or Ciabatta Thick-cut bread works best for a "gourmet" feel.
- 4 tbsp Basil or Herb Pesto Use high-quality store-bought or fresh homemade.
- 1 Handful Fresh Arugula (Rocket) Provides a peppery crunch to balance the salt.
- 6 Pieces Sun-dried Tomatoes Sliced; oil-packed adds a nice sweetness and tang.
- 1 tsp Olive Oil Just a drizzle for toasting the bread if not using a toaster.
- 1/2 tsp Chili Flakes (Optional) For a little kick of heat on the cheese.
- 1/2 Unit Lemon A quick squeeze over the arugula for brightness.
Instructions
-
Prep the Halloumi:
Slice the halloumi block into roughly 1cm thick slabs. Use a paper towel to pat them very dry—this is the secret to getting that crispy, golden crust instead of a soggy mess.
-
Toast the Bread:
Heat a grill pan or toaster. Lightly drizzle your sourdough or ciabatta with a bit of olive oil and toast until golden brown and crunchy. Set aside.
-
Sear the Cheese:
Place a non-stick skillet over medium-high heat. Add the halloumi slices to the dry pan (no oil needed!). Fry for about 2 minutes per side until they develop a deep golden-brown crust and start to soften in the middle.
-
The Pesto Base:
While the cheese is frying, spread a generous tablespoon of herb pesto onto the bottom slice of each piece of toasted bread.
-
Layer Up:
Place the warm, seared halloumi slices directly onto the pesto. Top with the sun-dried tomatoes and a pinch of chili flakes if you want a little heat.
-
The Fresh Finish:
Toss your arugula with a tiny squeeze of lemon juice and pile it high on top of the cheese. Close the sandwich with the remaining bread slice.
-
Serve:
Cut diagonally with a sharp knife and eat immediately while the halloumi is still warm and "squeaky."
Recipe Notes
Serving & Presentation
To get that authentic "expensive café" look, it’s all about how you stack and slice. Here is how to make it look as good as it tastes:
-
The Diagonal Cut: Use a sharp serrated knife to cut the sandwich diagonally. It creates a more dramatic "cross-section" where you can see the bright green pesto, the white-and-gold halloumi, and the red sun-dried tomatoes.
-
The Skewer Trick: If your sandwich is stacked high with arugula, use a wooden bamboo skewer or a toothpick with an olive through the center to hold everything in place. It adds a professional touch and keeps it from sliding apart.
-
The Garnish: Sprinkle a tiny pinch of flaky sea salt or extra cracked black pepper directly onto the exposed halloumi. A few extra torn basil leaves on the side of the plate makes the "herb" theme pop.
-
Side Pairing: Serve on a matte ceramic plate or a small wooden board. It pairs perfectly with a side of lightly salted kettle chips or a small bowl of balsamic-glazed cherry tomatoes.
-
Eat It Hot: Halloumi has a very specific "squeak" and soft texture when warm. Serve it within 2 minutes of frying; once it cools completely, the cheese becomes firm and loses that melty-yet-crispy magic.
