Spicy Crunch Jalapeño Popper Grilled Cheese Sandwich

In a medium bowl, combine 4 oz cream cheese with the diced jalapeños, 1 tbsp hot sauce, and ½ tsp smoked paprika. Stir until smooth and evenly colored. This mixture will be the spicy heart of the sandwich, so taste and adjust heat now if you prefer it milder or hotter.

Assembling the Sandwiches

1. Spread the jalapeño cream. Lay out four slices of sour‑dough bread, skin side up. Evenly spread the jalapeño‑cream mixture on each slice, leaving a thin border to prevent overflow during grilling.
2. Add the cheeses. Sprinkle a generous handful of shredded cheddar and mozzarella over the cream layer on each slice. The cheeses will melt into a gooey bridge between the two pieces of bread.
3. Close the sandwiches. Top each prepared slice with the remaining four slices of bread, skin side down, forming four complete sandwiches.
4. Prepare the crunch coating. In a shallow dish, mix ½ cup panko breadcrumbs, 2 tbsp melted butter, ¼ tsp garlic powder, and a pinch of salt and pepper. The butter binds the crumbs, creating a crisp crust when grilled.
5. Coat the exterior. Lightly brush the top of each sandwich with melted butter, then press the breadcrumb mixture onto the buttered side, ensuring an even layer. This step is crucial for that signature crunch.
