Add breadcrumbs and beef broth to a small bowl and stir until the breadcrumbs are coated. Set aside.
Add mushrooms, carrots, onions, and garlic to a large bowl and stir. Add eggs, soaked bread crumbs, ketchup, dijon mustard, Worcestershire sauce, and salt to the bowl and mix. Then, gently fold the beef into the mixture until you incorporate all the ingredients. Form the meatloaf into a loaf, ensuring it's tight and compact.
Preheat your air fryer to 360 degrees Fahrenheit (182°C). Place meatloaf in the air fryer basket. Cook for 20-25 minutes until the temperature reaches 165 degrees Fahrenheit (74°C).
While meatloaf is cooking, prepare the glaze by combining ketchup, brown sugar, and Dijon mustard in a small bowl. When there are about 5 minutes left on your timer, spread the glaze over the meatloaf in the Air Fryer.
Remove and allow meatloaf to rest for 10-15 minutes before slicing.

Notes
Ensure your air fryer basket is large enough to hold the meatloaf. I used an air fryer with a 5 quart basket.
You might line the air fryer basket with aluminum foil or parchment paper for easier cleanup and prevent the meatloaf from sticking. If using foil, leave some space around the meatloaf for air circulation. Do not add any paper to the air fryer while it is preheating.
