Why This Recipe Works
💡 Smashing When Fat Is Solid
Smashing during the first 30 seconds when fat is still solid creates maximum metal contact for Maillard browning without forcing out melted juices.
Ingredients for 2 ServingsUS Standard Measurements
- 0.75 lb 80/20 ground beef chuck, divided into four 2.5 oz balls
- 4 slices Real American cheese slices⭐ Recommended: Kraft Deli Deluxe
- 2 buns Potato burger rolls⭐ Recommended: Martin's Potato Rolls
- 2 tbsp Unsalted butter, softened (for toasting buns)

- 0.5 tsp Freshly cracked black pepper
Required Kitchen Tools

Step-by-Step Preparation
Toast Buns & Shape Loose Meatballs
Butter the cut sides of the 2 potato burger rolls with 2 tbsp softened butter and toast in the skillet until golden; set aside with 8 dill pickle chips on the bottom buns. Form cold 80/20 ground beef into 4 loose rough 2.5 oz balls without overworking.
Hard Smash in Dry Skillet
Place meatballs onto the dry smoking cast iron. Immediately smash down flat into thin wafers using a heavy rigid metal spatula and press.
Season and Brown
Season heavily with 1 tsp kosher salt and 0.5 tsp freshly cracked black pepper. Cook 2 minutes undisturbed until edges are dark and lace-like.
Scrape, Flip, and Melt
Scrape firmly under the crust to release, flip, top each patty with a slice of American cheese until melted (reaching ≥160°F / 71°C internal temperature), and stack two patties per butter-toasted potato bun over the dill pickles.
