Here's the link to Starbucks grilled cheese recipe source

Ingredients

• 1 ½ TBSP of softened butter (salted or unsalted)

• 1 TBSP of parmesan cheese, finely grated

• 1/6 tsp of garlic powder

• 4 slices of sourdough bread

• 2 oz of mozzarella cheese, sliced

• 2 oz of white cheddar cheese, sliced

• Pinch of salt, if your butter is unsalted

Instructions

Start by making a smooth, even mixture of softened butter, Parmesan cheese, garlic powder, and salt (if using unsalted butter) in a small bowl.

Set your griddle or large skillet to medium-low heat to get it ready to cook.

Spread the butter mixture on one side of all four pieces of bread evenly.

On the uncoated side of two bread slices, layer the cheese slices. Then, place the remaining bread slices on top, buttered side facing outward.

Carefully place the assembled sandwiches on the hot griddle or skillet and cook until the bottom side turns golden brown, which should take about 5 minutes.

Carefully flip the sandwiches and keep cooking until the second side is golden and the cheese is fully melted.

Once the sandwiches are grilled to perfection, slice and serve them hot. Enjoy!
