The feta is non-negotiable for that signature tang. Whole Foods carries excellent imported Greek feta in brine—avoid the pre-crumbled stuff, as it dries out faster. For olives, Kalata or Cerignola add the right briny depth. Trader Joe’s has great sun-dried tomatoes in oil at a fair price. Sourdough from a local bakery (the kind with a proper crust) holds up better than soft sandwich bread.
No feta on hand? Fresh mozzarella with a pinch of lemon zest mimics the acidity. Out of Kalata olives? Picholine or green olives work in a pinch. Sun-dried tomatoes can be swapped for roasted red peppers (jarred is fine). If fresh herbs are scarce, dried oregano at half the amount keeps the Mediterranean profile intact.
Assemble just before cooking to prevent sogginess. Leftovers? Press between paper towels to remove excess moisture, then store in an airtight container for up to 2 days. Reheat in a skillet to revive the crisp—microwaving turns the bread to mush.

Step-by-Step Instructions for Mediterranean Grilled Cheese Sandwich
Master this technique for a perfectly crisp exterior and rich, molten Mediterranean filling.
Step 1: Prepare the Flavorful Filling
In a bowl, combine the 8 oz Feta Cheese, 0.5 cup Kalata Olives, 0.25 cup Sun-Dried Tomatoes, 1 cup Fresh Spinach Leaves, and 0.25 cup Fresh Basil Leaves. The feta should be crumbled into small, uniform pieces to distribute evenly throughout each sandwich.
Drizzle with the 1 tbsp Extra-Virgin Olive Oil and add the 2 cloves Garlic Cloves (minced), 1 tsp Dried Oregano, 0.5 tsp Red Pepper Flakes, 0.5 tsp Kosher Salt, and 0.25 tsp Freshly Ground Black Pepper. Gently fold everything together until the spinach and basil are just wilted. This creates a cohesive filling with balanced Mediterranean flavors.
Step 2: Butter and Assemble the Sandwiches
Lay out the 8 slices Sourdough Bread and spread 1 tbsp of the 4 tbsp Unsalted Butter on one side of each slice. Use the softened butter to ensure even coverage to the edges—this guarantees maximum crispness when grilled.
Divide the filling evenly among four slices, placing it on the unbuttered side. Top each with another slice of bread, buttered side facing outward. Press down gently to compact the filling without squashing the bread.
Step 3: Grill to Golden Perfection
Heat a large skillet or griddle over medium heat. Once hot, add two sandwiches and cook for 3-4 minutes per side, or until the bread is golden brown and the cheese begins to melt.
Avoid pressing down with a spatula—this can squeeze out the filling. Instead, lift occasionally to check for even browning. The sandwiches are ready to flip when the underside is crisp and golden.
Step 4: Rest and Serve Immediately
Transfer the cooked sandwiches to a cutting board and let them rest for 1-2 minutes. This brief pause allows the cheese to set slightly, preventing it from oozing out when sliced.
Cut each sandwich diagonally and serve while hot. The exterior should be crisp and buttery, while the interior offers a creamy, tangy blend of feta with the briny olives, sweet sun-dried tomatoes, and fresh herbs.
Pro Tips For Making Mediterranean Grilled Cheese Sandwich
- Press with a Plate: After assembling, press the sandwich with a weighted plate for 2 minutes before grilling—this packs the feta and spinach tightly so they don’t spill out when the cheese melts.
- Drain the Tomatoes: Pat the sun-dried tomatoes dry with a paper towel first; their oil can make the bread soggy and prevent a good crust from forming.
- Skip Raw Spinach: I learned this the hard way—wilt the spinach in a dry pan for 30 seconds first, or it’ll release too much water and turn your sandwich into a mushy mess.
- Butter the Outside: Sounds obvious, but use softened butter on the outer bread slices, not oil—it browns better and adds that rich, toasted sourdough flavor you want.
Storing and Reheating mediterranean grilled cheese sandwich
Refrigerator Storage
Let your sandwiches cool for 10-15 minutes before wrapping them tightly in parchment paper, then aluminum foil. Store in the fridge at 40°F or below for up to 2 days. The feta holds up surprisingly well.
Freezer Storage
For longer storage, wrap each sandwich individually in plastic wrap, then place in a freezer bag with parchment between layers. They’ll keep for up to 1 month, though the bread texture changes slightly. I always label with the date. ❄️
Skillet Reheating
My go-to method for reviving crispness. Heat a skillet over medium-low heat, add the sandwich, and cover with a lid for 2-3 minutes per side. The steam melts the cheese while the bread re-crispes beautifully.
Oven Reheating
Preheat your oven to 375°F and place sandwiches on a baking sheet. Bake for 8-10 minutes, flipping halfway. This works great for multiple sandwiches at once and maintains even heating.
Avoid the Microwave
While it’s the fastest option, microwaving turns the sourdough soggy. If you must, use 50% power for 30-45 seconds and place a paper towel underneath to absorb moisture. Even then, it’s not ideal.
