This is the pub-style steakhouse burger you make just because you want to flex. Half-pound, hard-seared crust, golden mushrooms, sharp cheddar, Dijon-mayo — cast iron or smoke-and-sear options for whatever you're craving.
1tsp1 tsp freshly cracked black pepper or steak seasoning
For the Mushrooms
8oz8 oz cremini or button mushrooms, sliced
1tbsp1 tbsp butter
1pinch1 pinch kosher salt
For the Sauce and Assembly
2tbsp2 tbsp mayonnaise
1tsp1 tsp Dijon mustard
2slices2 slices sharp cheddar
22 brioche or pub rolls, split
Butter or oil for toasting
4–6slices4–6 slices thick-cut bacon, cooked through
1 handful arugula
Instructions
Form the Patties
Divide beef into two portions and gently form into loose patties ¾–1 inch thick. Press a shallow dimple in the center. Season outsides with salt and pepper right before cooking.
Cook the Mushrooms
Heat cast iron over medium-high with no fat. Add mushrooms and a pinch of salt. Cook 6–8 minutes until moisture cooks off completely and the pan sounds dry. Add butter, cook 1–2 minutes more until mushrooms are golden. Transfer to a plate.
Sear the Burgers
Add patties to the same hot skillet. Don't touch for 4–5 minutes until a dark crust forms and the patty releases cleanly. Flip once, lower heat slightly, cook 3–4 more minutes. Pull at 130°F for medium-rare or 140°F for medium.See the notes below for smoking these burgers.
Melt the Cheese
Top each patty with sharp cheddar in the final minute. Cover briefly if needed. Remove from heat and rest 3–4 minutes.
Toast the Buns
Butter cut sides and toast in the pan until golden.
Assemble
Mix the mayo and Dijon in a small bowl together, then spread it on the bottom bun. Add the arugula, a smoked patty, spoon mushrooms over top, layer on the bacon, top with the remaining bun halves, and serve.
Notes
Don't salt ground beef before forming - season the exterior only, right before cooking.
Chill patties 30 minutes before smoking for better structure.
Store cooked patties and mushrooms separately, refrigerated up to 3 days. Reheat covered in a skillet at low heat or in the oven at 325°F for 8–10 minutes.
To smoke these:
Preheat your smoker to 225°F and add a hickory or post oak chunk. Chill the patties 30 minutes before smoking: cold fat holds together on the low-and-slow and gives you a better crust on the sear. Season the patties right before they go in and smoke 30–45 minutes until the internal temp reads 130°F.
Then move fast - get a cast iron or charcoal grill screaming hot (450°F+) and sear 2–3 minutes per side until the crust forms and the internal temp hits 135°F for medium-rare or 145°F for medium.
Add cheddar in the final minute and close the lid to melt. The smoke adds a depth the skillet method can't touch.
