Add a new, quick weeknight meal to your rotation with these savoury beef and blue cheese stuffed mushrooms that air fry to juicy perfection inside with an amazing crust on top. Served up with a salad of greens, this recipe makes enough to serve 2 as a main course or 4 as a plated appetizer. Note: Cook times suggested are based on a counter-top family-size air fryer**; times will vary with different appliances so always check for doneness with a reliable digital instant-read thermometer and texture cues and adjust cook time as necessary. Ground beef is done when the thermometer reads 160°F (71°C).
