Melt butter in a skillet over medium heat and add the onions to sauté for about 10 minutes, stirring occasionally, until it starts turning a golden color.

Step 1

Add the rest of the butter along with the mushrooms, sugar, and salt and continue to sauté for another 5 minutes until the mushrooms have cooked through. Remove from the heat and set those aside.

Step 2

Open the buns and lay both halves face side down onto a greased grill or skillet to toast until crispy. Remove them and set them aside, open faced.

Step 3

Grease the grill once more and cook the burger patties, flipping halfway, until cooked through and desired doneness has been reached. While they’re on the grill, sprinkle with Montreal steak spice on both sides.

Step 4

Place a slice of American cheese on each one of the patties to melt.

Step 5

1. Spread mayo and sriracha sauce over both halves of the bun. 2. Place 2 patties (optional, you can definitely stick to 1 if you’d like) with melted cheese onto the bottom bun.

Step 6

3. Top with sliced red onions, a slice of tomato, leaf of lettuce, and of course the caramelized onions and mushrooms. Close it up with the top bun.

Step 7

4. Fill a stainless steel syringe filled with nacho cheese and pierce it right into the burger. If you want to get fancy, especially when serving a crowd, serve the burger with the cheese syringe in it! Squeeze the nacho cheese into the burger and enjoy!
