Prepare the Burger Patties:
Combine the ground beef with salt, pepper, and garlic powder. Shape into two equal-sized patties.
Cook the patties in a skillet or on a grill over medium-high heat for about 3–4 minutes per side, depending on desired doneness.
Add a slice of cheddar cheese on top of each patty during the last minute of cooking to let it melt.
Cook the Bacon and Mushrooms:
In a separate skillet, cook the bacon strips until crispy and set aside on a paper towel.
In the same skillet, melt the butter and sauté the mushrooms until tender and golden brown, about 5 minutes.
Caramelize the Onions:
In a separate pan, cook the sliced onions over low heat with a bit of butter until they’re golden and caramelized.
Toast the Bun:
Butter the cut sides of the burger bun and toast in a skillet or on the grill until golden and slightly crispy.
Assemble the Burger:
Place the bottom bun on a plate.
Add caramelized onions as the base layer.
Place the first cheese-topped burger patty on top.
