In a mixing bowl, combine the softened unsalted butter, minced garlic, 2 teaspoons of the chopped parsley, and grated Parmesan cheese if you're using it. Mix until well combined.
Take your baguette and slice it into 1-inch thick pieces.
Using a butter knife, generously spread the garlic butter mixture on one side of each slice of baguette.
Preheat your air fryer to 350°F (175°C).
Arrange the slices of baguette in a single layer in the air fryer basket.
Cook the garlic bread in the air fryer for about 5-7 minutes, or until golden brown and crispy.
Once cooked, remove the garlic bread from the air fryer and sprinkle the remaining teaspoon of chopped parsley on top. Serve immediately.
