Ingredients

The following ingredients have 4 Servings
  • 1 lb lean ground beef ((454 grams; I used 90/10 ground burger))
  • 1 tablespoon Montreal steak seasoning ((or your favorite burger seasoning))
  • 3 slices Muenster cheese ((23 grams per slice; can substitute with your favorite sliced cheese))
  • cooking oil spray

Instruction

  • With clean hands, thoroughly mix the seasoning and ground beef together.
  • Divide the beef mixture into 6 equal pieces. Make 3 of the pieces into very flat and large (4-inch/10 cm diameter) patties with no holes. Make the other 3 pieces into balls.
  • Cut each slice of the cheese into four pieces. Stack four pieces (one slice) of cheese atop each of the flattened patties.
  • Take the burger pieces that you formed into balls. Flatten each one out and use them to completely cover the cheese on the patties. Seal the edges of each burger. The cheese should now be completely encased within each patty.
  • Mist an air fryer rack with the cooking spray. Your burgers should all fit on one rack in a single-layer (if you have a large air fryer oven).
  • Put the rack with the burgers in the top position in the oven. Bake at 375°F (190°C) for 5 minutes. Then carefully flip the burgers and replace the rack in the top position in the oven. Bake for an additional 5 minutes at 375°F (190°C).
  • This recipe makes burgers that are cooked to medium doneness. Minimum safe internal temperature for ground beef is 160°F (71°C), which is well done. Adjust the cooking times to match your needs and preferences. Remember that color of the burger isn't a good doneness indicator, temperature is!
  • Let the burgers rest for a few minutes before topping as desired. Enjoy!
