Pizza Grilled Cheese Sandwich Recipe: Three-Cheese Melt on Toasted Bread

This isn’t your childhood grilled cheese. A three-cheese blend and classic pizza flavors come together between slices of toasted bread for a meal that’s both nostalgic and elevated.

I developed this recipe to satisfy cravings for both pizza and comfort food in one. The technique ensures melty cheese and a golden crust without the fuss of dough or sauce prep.

The cheese selection is critical for optimal melt and flavor. Whole Foods carries an excellent low-moisture mozzarella, while Trader Joe’s offers a pre-shredded three-cheese pizza blend that works beautifully. For Parmesan, always grate from a wedge—pre-grated versions contain anti-caking agents that prevent smooth melting. Sourdough provides the necessary structure to hold the fillings without becoming soggy.

Vegetarian pepperoni from Lightlife or Yves mimics the classic flavor without meat. Swap provolone for fontina or Gruyère for a more complex taste. No pizza sauce? Tomato paste thinned with water works in a pinch. The garlic powder can be replaced with fresh minced garlic at a 1:1 ratio. For extra depth, add a pinch of fennel seeds to the cheese mixture.

Assemble sandwiches just before cooking to prevent sogginess. Store unused cheese in airtight containers for up to 2 weeks. The pizza sauce keeps for 5 days refrigerated or 3 months frozen. Toasted sandwiches are best served immediately but can be reheated in a skillet for 2-3 minutes per side.

Step-by-Step Instructions for Pizza Grilled Cheese Sandwiches

Master the technique with precision timing and professional layering for optimal results.

Step 1: Prepare the Cheese Blend and Sauce Mixture

In a bowl, combine the 8 oz Mozzarella Cheese, 4 oz Provolone Cheese, and 0.5 cup Parmesan Cheese. The combination of these three cheeses creates a perfect melt with depth of flavor and ideal stretch. The low-moisture mozzarella ensures a smooth, stringy texture without excess liquid.

In a separate small bowl, mix the 0.75 cup Pizza Sauce with the 1 tsp Garlic Powder, 1 tsp Dried Oregano, 0.25 tsp Red Pepper Flakes, and 1 tsp Dried Basil. This infuses the sauce with aromatic complexity that elevates the sandwich from simple to gourmet.

Step 2: Assemble the Sandwiches with Strategic Layering

Lay out 4 slices of Sourdough Bread and brush the outer sides with the 1 tbsp Olive Oil. This creates an extra-crispy exterior when grilled. On the inner side of each slice, spread an even layer of the seasoned pizza sauce, leaving a small border to prevent spillage.

Divide the cheese blend evenly among the four slices, then distribute the 20 slices Pepperoni Slices on top of the cheese. The pepperoni should be placed directly against the cheese so its oils can meld into the mix. Top each with another slice of sourdough bread, oil-side out, to complete the sandwiches.

Step 3: Grill to Golden Perfection with Weighted Press

Heat a large skillet or griddle over medium heat. Add 2 tbsp Butter and let it melt completely, swirling to coat the surface evenly. Place two sandwiches in the pan and cook for 3-4 minutes until the bread turns golden brown and the cheese begins to melt at the edges.

Carefully flip the sandwiches and add the remaining 2 tbsp Butter to the pan. Press down gently with a spatula to ensure even contact and complete melting. Cook for another 3-4 minutes until the second side is equally golden and the cheese is fully melted throughout. The sandwich should be crisp on the outside and gooey on the inside.

Step 4: Rest and Serve for Maximum Structural Integrity

Transfer the sandwiches to a cutting board and let them rest for 2 minutes. This brief pause allows the cheese to set slightly, preventing it from oozing out when you cut into it. The rest also lets the flavors meld together for a more cohesive taste.

Slice each sandwich diagonally and serve immediately while hot. The ideal result features a crisp, buttery exterior giving way to a rich, three-cheese interior with pockets of spicy pepperoni and herbed tomato sauce in every bite. The structural integrity of the thick-cut sourdough ensures it holds up to the generous fillings without becoming soggy.

Storing and Reheating This Dish

Refrigerator Storage

Let your sandwiches cool completely before storing—I use glass containers with snap-tight lids to maintain freshness. They’ll keep in the fridge at 40°F or below for up to 3 days. The flavors deepen overnight as the herbs and spices meld together. ❄️

Freezer Storage

For longer storage, wrap each cooled sandwich individually in parchment paper, then place in a freezer bag. Squeeze out excess air to prevent freezer burn. These will stay fresh for up to 2 months without losing texture or flavor.

Skillet Reheating

This is my go-to method for reviving that fresh-off-the-griddle taste. Heat a skillet over medium-low heat, add the sandwich, and cook for 2-3 minutes per side until the cheese remelts and the bread crisps up again. Add a pat of butter for extra richness. 🔥

Air Fryer Option

Preheat your air fryer to 350°F and reheat for 3-4 minutes, flipping halfway. This method works great for a quick, crispy result. Watch closely to avoid over-browning the sourdough.

Microwave Quick Fix

For a fast option, microwave on 50% power for 30-45 seconds. Place a damp paper towel over the sandwich to prevent drying. The cheese will soften, but the bread won’t be as crispy as other methods.
