If you want to make the burger buns then keep reading but if you bought burger buns already then skip to step 4.Follow the instructions to make the dinner roll recipe but instead of shaping into 8 balls we will shape into 6. Rest for about an hour. Cover with plastic wrap.
Set the oven to 175°C/350°F. Carefully brush the hamburger buns with the egg wash. Sprinkle generously with sesame seeds.
Bake in the oven for 10 minutes, turn and then back in the oven for 7 minutes more. When they reach 200°F on a thermometer they're perfect.
Season the burgers generously with salt and pepper in a bowl and mix thoroughly.
Roll the burgers into balls first, then stuff the butter cubes in the middle. Make the cubes a little smaller than in the picture for best results.
Shape the burgers with clean hands into burger patties. Make sure the butter is completely covered by the meat.
Get all the other ingredients ready to go. Fry the bacon until crispy and then cook the mushrooms in the bacon fat. Make the mac sauce. Slice the cheese, pickles, tomatoes, and pick the lettuce. Have everything ready to go so when the burgers are ready, you are ready.
Fire up the BBQ and grill the burgers over medium high heat. Quarter turn once, then flip, then quarter turn again. This takes about 10-15 minutes in total.
Once the burgers are almost ready add the cheese and bacon. Cook to 160°F/71°C.
Slice the buns and toast them if you like. On the top add the sauces, lettuce, tomatoes and pickles. On the bottom put the mushrooms and then the burger with the cheese and bacon. Hold together with a toothpick if necessary. Enjoy!
