Cast Iron Skillet Burgers
A cast iron skillet holds and retains far more heat than a nonstick pan or a grill grate exposed to open air, so the patties develop a thick, dark crust through fast, even contact with the surface, all while the fat rendering out gets reabsorbed into that crust instead of dripping away.

Instructions
- 1Divide the ground beef into 4 equal portions, about 6 oz each, and shape loosely into balls without compacting the meat.
- 2Place the cast iron skillet over high heat for a full 4-5 minutes, until it's visibly smoking slightly. Add the oil and swirl to coat.
- 3Set a meat ball in the skillet and immediately press it flat with a sturdy spatula (or the bottom of another pan) into a patty about 1/2 inch thick and wider than the bun. Repeat with the remaining portions, working in batches if needed to avoid crowding the pan.
- 4Season the tops generously with salt and pepper. Sear undisturbed for 2-3 minutes, until a deep brown crust forms and the edges look crisp and lacy.
- 5Flip each patty, season the second side, and cook for another 2 minutes for medium doneness. Add a slice of cheese during the last minute and let it melt.
- 6Meanwhile, butter the cut sides of the buns and toast them in a separate pan or under the broiler until golden.
- 7Rest the patties on the buns for 1-2 minutes before adding toppings and serving.
Tips & variations
- An 80/20 fat ratio is the sweet spot for cast iron; leaner blends dry out fast under this much direct heat.
- Press the patties within seconds of them hitting the oil, cast iron loses heat quickly once a cold ball of meat sits on it, and a delayed press won't sear as aggressively.
- For a smash-burger double, use 3 oz portions per patty and stack two per bun instead of using one thicker patty.
- A splash of Worcestershire sauce mixed into the beef before shaping adds savoriness without needing extra binders.
Storage & reheating
Store cooked patties in an airtight container in the refrigerator for up to 3 days. Reheat in a dry skillet over medium heat for 1-2 minutes per side, or in a 300°F oven for about 10 minutes, to avoid drying them out in the microwave.
Tips from the Tulo kitchen
- A well-seasoned skillet releases the crust cleanly once it's actually formed; if the patty resists lifting, it usually needs another 30 seconds, not more oil.
- Letting the beef sit at room temperature for 10-15 minutes before cooking helps it sear more evenly than beef straight from the fridge.
FAQ
Why does cast iron work better for burgers than a nonstick pan?
Cast iron holds far more thermal mass, so its surface temperature doesn't crash the moment a cold patty is added, which is what allows a thick, dark crust to form in just 2-3 minutes instead of the meat gradually graying and steaming.
Do I need to add oil if the skillet is well-seasoned?
Yes, a thin layer of oil still helps with even heat transfer and easier release, even on a well-seasoned pan; skip it and the fatty edges of the patty can still stick before enough fat has rendered out.
What internal temperature means the burger is done?
140°F for medium, 145°F for medium-well, and 160°F for well-done, checked with an instant-read thermometer inserted sideways into the center of the patty.
Should I use a lid while searing?
No, a lid traps steam and softens the crust that direct, dry heat is meant to build; leave the skillet uncovered through both sides of the sear.
