Slice your baguette lengthwise into two halves, then cut each half into 4-inch pieces. Lay them cut-side up on a clean cutting board and pat gently with paper towels to remove excess moisture—drier surfaces crisp more efficiently in the air fryer basket.
Combine softened butter with minced garlic in a small bowl, stirring until the mixture becomes uniform and pale. Add salt, black pepper, garlic powder, and red pepper flakes to the butter, whisking to distribute seasonings evenly throughout.
Brush the garlic butter generously onto each bread piece's cut surface using a pastry brush, ensuring complete coverage with no dry spots. Beautiful air fryer garlic bread recipe depends on even butter distribution—rushed application results in inconsistent browning and texture.
Arrange prepared bread pieces cut-side up in your air fryer basket in a single layer without overlapping. Set temperature to 350°F and cook for exactly 8 minutes, checking at the 6-minute mark for your specific air fryer model's heat distribution patterns.
Remove the basket carefully and sprinkle Parmesan cheese, fresh parsley, fresh basil, and lemon zest immediately over the hot bread. The residual heat melts the cheese slightly while the fresh herbs remain vibrant—this creates the visual appeal that makes this beautiful side unforgettable.
Return to the air fryer for exactly 2 minutes at 350°F to set the cheese and warm the fresh herbs through without wilting them. The final result should display a deep golden-brown crust with glistening cheese and verdant herb flecks.
