How to make a Juicy Lucy — the cheese-stuffed burger with a molten core. The best cheeses, the sealing technique, and how to avoid blowouts.
The Juicy Lucy flips the cheeseburger inside out, sealing the cheese inside the patty so it melts into a molten, lava-like core. When you bite in, hot cheese oozes out — it's a glorious mess. Here's how to make a Juicy Lucy at home and avoid the dreaded cheese blowout.
What a Juicy Lucy Is
The Juicy Lucy (or Jucy Lucy) is a burger with the cheese cooked inside the patty rather than melted on top. Famously associated with Minneapolis bars, it's made by encasing cheese between two thin patties sealed into one, so that as the burger cooks, the cheese melts into a hot, gooey center. The reward is a burst of molten cheese with every bite — though the molten cheese is very hot, so the first bite needs caution.
Choosing the Cheese
The ideal cheese for a Juicy Lucy melts smoothly and flows. American cheese is the classic and arguably best choice — its emulsifiers make it melt into a perfectly smooth, molten core without separating. Other good melters like cheddar, Monterey Jack, or pepper jack work too, though they may not flow quite as smoothly. Use the cheese folded or cut into a compact piece that fits within the patty with room to seal around it.
Forming and Sealing the Patties
This is the crucial step. Divide your ground beef into two thin patties per burger. Place a small, compact piece of cheese in the center of one patty, keeping it well away from the edges. Top with the second patty and press the edges firmly together all the way around, sealing them completely so no cheese can escape. Make sure there are no cracks or thin spots. A well-sealed patty is the key to keeping the cheese inside.
Avoiding the Blowout
The "blowout" — where the cheese bursts out during cooking — is the main pitfall. To prevent it: seal the edges thoroughly with no gaps, don't overstuff with cheese, and avoid pressing down on the burger as it cooks (no smashing). Cook over medium heat rather than blazing high heat, which can rupture the patty. And don't pierce the burger. A gentle, patient cook keeps the molten core contained.
Cooking the Juicy Lucy
Cook the sealed patties over medium heat in a skillet or on a grill, turning once, until cooked through and the cheese inside is fully melted — this takes a bit longer than a regular burger because of the thickness and the need to melt the core. Because the cheese is sealed in, you'll want the patty cooked through to ensure the center is molten. Let it rest a minute before serving, and warn everyone that the cheese inside is extremely hot.
Serving
Serve the Juicy Lucy on a toasted bun with classic burger fixings — lettuce, tomato, onion, pickles, and sauce — but go easy, since the star is the molten cheese core. The first bite releases a flow of hot cheese, so let it cool slightly before diving in. Pair with fries and a cold drink for the full indulgent experience.
Frequently Asked Questions
What cheese is best for a Juicy Lucy?
American cheese is the classic, melting into a perfectly smooth, molten core; cheddar, Monterey Jack, or pepper jack also work.
How do I keep the cheese from leaking out?
Seal the two patties together firmly all around with no gaps, don't overstuff, cook over medium heat, and never press or pierce the burger.
Why is the first bite of a Juicy Lucy dangerous?
The sealed-in cheese gets extremely hot and molten, so it can burn your mouth — let the burger cool slightly before biting in.
