Preheat your air fryer to 350°F (175°C) for 3-5 minutes while you prepare the meatloaf mixture.
In a large bowl, combine milk and breadcrumbs and let sit for 2-3 minutes until the breadcrumbs absorb the moisture.
Add ground beef, diced onion, bell pepper, garlic, beaten egg, Worcestershire sauce, and all seasonings to the bowl. Mix gently with your hands just until combined—avoid overmixing as it can make the meatloaf tough.
Shape the meat mixture into a loaf that will fit your air fryer basket, leaving some space around the edges for air circulation. If your air fryer is smaller, consider making two smaller loaves.
Line your air fryer basket with parchment paper or foil with small holes punched in it to allow for drainage while still making cleanup easier.
Place the meatloaf in the air fryer and cook for 15 minutes at 350°F (175°C).
While the meatloaf cooks, make the glaze by combining all glaze ingredients in a small bowl and stirring until smooth.
After 15 minutes, carefully brush the top and sides of the meatloaf with half the glaze and continue cooking for 5 minutes.
Apply the remaining glaze and cook for a final 5 minutes or until the internal temperature reaches 160°F (71°C).
Let the meatloaf rest for 5-10 minutes before slicing to allow juices to redistribute throughout the meat.
