Start by melting the butter in a microwave-safe bowl. Add minced garlic and parsley to the bowl, stirring until combined. The garlic butter is what makes the bread so flavorful and crispy, giving it that golden perfection.
Take your shredded chicken and place it in a medium bowl. Mix it thoroughly with paprika, Worcestershire sauce, and BBQ sauce. You’ll want each piece of chicken to be coated in that tangy, smoky goodness.
Heat olive oil in a skillet over medium heat. Toss in the thinly sliced red onions and cook for about two minutes, just until they soften. Stir occasionally to prevent them from sticking. These softened onions add a subtle sweetness to balance the BBQ flavors.
Lay the slices of bread out on your work surface. Spread the garlic butter evenly on one side of each slice. Flip six slices so the buttered side faces down. Layer Havarti cheese, then spread an even portion of the BBQ chicken mixture on top. Add a second layer of Havarti before topping it with the other six slices of bread, buttered side up.
Place the sandwiches in the skillet over medium heat. Grill for 3-5 minutes on one side until golden brown, then flip them carefully using a spatula. Lower the heat slightly and cook for another 3-5 minutes until the cheese melts and the second side is golden. The result is a crisp, cheesy sandwich that’s irresistible.
