Method
Make the patties
- In a mixing bowl, combine ground beef with Worcestershire sauce, salt, and garlic powder, then form into 4 patties.
- Set patties aside while you caramelize the mushrooms and onions.
Sauté the mushrooms and onions
- Melt butter in a cast iron skillet over medium heat, then add sliced mushrooms, sliced onion, thyme, salt, and pepper.
- Cook for 15–20 minutes, stirring occasionally, until golden and caramelized.
Cook and melt the cheese
- In a separate cast iron skillet or grill pan over medium-high heat, cook the patties for 3–4 minutes per side until cooked to your liking.
- Top each patty with a slice of Monterey Jack cheese, cover the pan, and heat for 1 minute until melted.
Assemble
- Plate each patty and smother it with the mushroom and onion mixture.
- Serve immediately over french fries.
Notes
For the best sear, let the patties sit at room temperature for 5 minutes before cooking and don’t press them while they cook. Store leftovers in an airtight container in the fridge for 3 days; reheat in a skillet until warmed through. Freezing is not recommended for best cheese texture. For a lower-fat swap, use 90/10 ground beef and add an extra pinch of salt to keep the flavor bold.
