A delicious twist on the classic grilled cheese sandwich, featuring a creamy and flavorful filling.
Combine the shredded cheddar cheese, sour cream, and caramelized onion in a mixing bowl until well blended.
Ensure the onion is fully caramelized for a sweeter, richer flavor.
Spread the filling evenly over two slices of bread.
Use a spoon or spatula to spread the filling smoothly and evenly.
Top each with another slice of bread, buttering the outer sides.
Butter the bread evenly to achieve a golden, crispy crust.
Heat a skillet over medium heat and cook the sandwiches until golden brown on both sides and the cheese is melted.
Press gently with the spatula while grilling for even cooking.
Slice the sandwiches in half and serve warm.
Serve with a side of tomato soup or a fresh salad for a complete meal.
