02 - 1 tbsp unsalted butter
03 - 1 tbsp olive oil
04 - 1/2 tsp salt
05 - 1 tsp sugar
→ Sautéed Mushrooms
06 - 9 oz cremini or button mushrooms, sliced
07 - 1 tbsp unsalted butter
08 - 1 tbsp olive oil
09 - 1 garlic clove, minced
10 - Salt and black pepper, to taste
→ Beef Patties
11 - 1.3 lbs ground beef (80/20 blend)
12 - 1 tsp salt
13 - 1/2 tsp black pepper
14 - 1 tsp Worcestershire sauce
→ Assembly
15 - 4 hamburger buns, split
16 - 4 slices Swiss or cheddar cheese
17 - Lettuce leaves
18 - Tomato slices
19 - Mustard, mayonnaise, or ketchup
# How to make it:
01 - Heat butter and olive oil in a large skillet over medium-low heat. Add sliced onions and salt. Cook, stirring occasionally, for 20–25 minutes until onions are golden and caramelized. Add sugar if desired to accelerate browning. Remove from heat and set aside.
02 - In another skillet, heat butter and olive oil over medium heat. Add mushrooms and cook for 5–7 minutes, stirring occasionally, until browned and tender. Add minced garlic and cook for 1 minute more. Season with salt and pepper. Remove from heat.
03 - In a bowl, gently combine ground beef with salt, pepper, and Worcestershire sauce. Divide into 4 equal portions and shape into patties slightly larger than your buns to account for shrinkage during cooking.
04 - Heat a grill pan or skillet over medium-high heat. Cook patties for 3–4 minutes per side for medium doneness. Place cheese slices on patties during the final minute of cooking to melt. Let patties rest for 1 minute before assembling.
05 - Lightly toast the buns, cut side down, in a dry pan or on the grill until golden and crisp.
06 - Layer lettuce on the bottom bun, add the beef patty, top with caramelized onions and sautéed mushrooms. Add tomato slices and condiments as desired. Complete with the top bun and serve immediately.
# Expert tips:
01 -
- The combination of sweet onions and earthy mushrooms transforms an ordinary burger into something restaurant quality
- Everything cooks in one pan system making cleanup surprisingly manageable
02 -
- Caramelizing onions takes patience but rushing them over high heat makes them bitter instead of sweet
- Don't press down on the patties while cooking or you will lose all those precious juices
03 -
- A well seasoned cast iron skillet creates the best crust on both patties and mushrooms
- The onions are done when they are reduced to about one fourth of their original volume
