Mushroom & Onion Cheeseburger

From Are You a Cheeseburger?

Jammed with cheese in the middle and a second layer of cheese on top, you’ll love the creaminess they bring to a burger. Topped with my favourite Chanterelle & Onion Jam and caramelized onions, bacon and a smoky bbq sauce, that’s one decadent burger!

Prep        20 minutes

Cook       10 minutes

Serves     4


  • 1 lb (450 g) ground sirloin beef
  • 1 lb (450 g) ground lamb (or pork)
  • 1 clove garlic, crushed
  • 1 small white onion, grated
  • 1 tsp (5 ml) dried oregano
  • 1 Tbsp (15 ml) dried parsley
  • Sea salt and freshly ground pepper
  • 150 g package Caramelized Onion & Herb (or other favourite flavour) Boursin cheese
  • 8 slices Abbot’s Gold Caramelised Onion Cheddar, cut ¼ inch (6 mm) thick
  • 4 good-quality burger buns (like Brioche)
  • Your favorite burger toppings like caramelized onions, bacon, bbq sauce


  1. Preheat the barbecue or indoor grill to 350°F (180°C).
  • In a large bowl, combine the beef, lamb (pork), garlic, onion, oregano, and parsley. Form thin 8 patties. On four of the patties, top 1 tbsp of Boursin cheese. Top this with a second patty and seal the two patties together around the edges. Sprinkle with salt and pepper.
  • Grill the burger patties, flipping only once, for approximately 5 minutes per side or until the internal temperature reaches 160°F (70°C). About 2 minutes before the burgers are done, top them with the cheddar cheese.
  • Let the burgers rest for 1 minute off the heat, allowing the cheese to continue melting, and then place the burgers on the buns and dress appropriately.

Nada’s Tips & Tricks: These are my family’s favourite burgers…ooey, gooey bites of yumminess. Experiment with different cheeses and toppings or lay out an array of choices to make each one unique. Lots of fun!
