A delightful twist on the classic grilled cheese, featuring caramelized onions and Swiss cheese for a gourmet touch.
Heat a skillet over medium heat and melt half of the butter.
Using unsalted butter allows you to control the saltiness of the dish.
Add the sliced onions to the skillet and cook, stirring occasionally, until they are caramelized and golden brown, about 20 minutes.
Cook the onions slowly to bring out their natural sweetness.
Spread the remaining butter on one side of each bread slice.
Ensure the butter is softened for easy spreading.
On the unbuttered side of half the bread slices, spread a thin layer of Dijon mustard.
Adjust the amount of mustard to your taste preference.
Top the mustard-spread slices with caramelized onions, Swiss cheese, and pickles. Cover with the remaining bread slices, buttered side up.
Layer the ingredients evenly for consistent flavor in each bite.
Heat the skillet over medium heat and grill the sandwiches until the bread is golden brown and the cheese is melted, about 3-4 minutes per side.
Press the sandwiches gently with a spatula for even grilling.
Cut the sandwiches in half and serve warm.
Serve with a side of soup or salad for a complete meal.
