While the air fryer is preheating, prepare the garlic butter spread. In a mixing bowl, combine the softened butter, minced garlic, and optional chopped parsley. Mix well until all the ingredients are fully incorporated.
Cut the French bread or baguette in half lengthwise.
Spread the garlic butter mixture evenly over the cut sides of the bread.
Sprinkle the shredded mozzarella and grated Parmesan cheese over the buttered bread. Make sure to cover the bread evenly with the cheese.
Season the bread with a pinch of salt and some freshly ground black pepper to taste.
Place the prepared garlic bread halves in the preheated air fryer. Depending on the size of your air fryer, you may need to do this in batches.
Air fry the cheesy garlic bread at 350°F (175°C) for about 5-8 minutes or until the cheese is melted and the bread is crispy and golden brown. Cooking times may vary depending on the air fryer model, so keep a close eye on it to prevent burning.
Once done, carefully remove the garlic bread from the air fryer. It will be hot, so use tongs or a spatula to handle it.
Let the cheesy garlic bread cool for a minute or two before slicing it into smaller pieces for serving.
Optionally, garnish with more fresh chopped parsley or additional grated Parmesan cheese before serving…
