These Cast Iron Burgers are half-pound, restaurant-quality burgers with a thick, juicy center and a deeply seared crust. Finished in the oven for even doneness, this foolproof method delivers big flavor and perfectly cooked burgers every time—no grill needed.
Preheat the oven to 350°F and the skillet on the stove top over medium heat.
Divide the ground beef into 4 ½ pound (8 ounce) portions.
Season each portion with ½ teaspoon seasoning salt and form into patties.
Melt butter in skillet.
Add patties to skillet, 2 at a time.
Cook for 3-4 minutes on the first side then flip and cook for an additional 3 minutes. Do not disturb the patties while cooking.
Place the skillet (with the patties in it) in the oven and cook for 10 minutes or until they've reached the desired temperature (160°F).
Turn off the oven and add the cheddar cheese slice to each patty and place it back in the warm oven to melt; about 2 minutes.
Serve on bun with your favorite condiments.
Notes
Start with a Hot Skillet: Preheat the cast iron until fully hot before adding the burgers. You should hear an immediate sizzle—this is essential for building a deep, crispy crust.
Don’t Crowd the Pan: Use at least a 12-inch skillet to cook all the burgers at once, or cook two at a time in a 10-inch skillet. Giving the burgers space helps them sear instead of steam.
Finish in the Oven: After searing, transfer the skillet to the oven and cook for about 10 minutes. This allows thick, half-pound burgers to cook evenly through the center without burning the exterior.
Press a Center Dent: Before cooking, press a shallow dent into the center of each patty. This helps prevent the burgers from puffing up and promotes even cooking.
Cook Undisturbed: Let the burgers cook without moving them until a crust forms. Flipping too early can tear the surface and prevent proper browning.
