Lotteria Double Cheeseburger Copycat Recipe

To make a Lotteria Double Classic Cheeseburger at home, sear two thin beef patties per burger, melt a slice of processed cheddar on each, and stack them on a soft, buttery bun spread with mayonnaise and mild mustard. Top with finely chopped onion and two pickle slices. No lettuce: the original has none. This is my copy of the burger Lotteria sells in South Korea as 더블 클래식치즈버거(버터번), the Double Classic Cheeseburger (butter bun), checked against the Korean menu in October 2026. It is not Lotteria’s recipe. The chain has never published patty weights or sauce formulas, and I flag every estimate below.

What’s in the Lotteria Double Classic Cheeseburger?

The Lotteria Double Classic Cheeseburger is a bun, two beef patties, two slices of cheese, mayonnaise, mustard sauce, chopped onion and pickles, with no lettuce or tomato. It builds on the Classic Cheeseburger (클래식 치즈버거), which Lotteria Korea launched on December 6, 2016, according to Herald Business. The Double keeps that base and doubles the patty and the cheese, as The Edit lists.

At launch, Lotteria described a handmade potato-style bun leavened with fermented whole-wheat starter, a thick patty of Australian beef and cheddar melted onto the patty. Each burger, the chain said, was made to order and balanced on three things: bun, patty, cheese. Today’s Korean menu sells the Double on a butter bun instead. When the bun changed, and what goes into it, Lotteria hasn’t said.

Why the Lotteria cheeseburger has no lettuce

Lotteria left lettuce off the Classic Cheeseburger on purpose, to put the beef and cheese first. Herald Business and a December 2016 Brunch review both report it. Korea Times columnist Jon Dunbar called it a stripped-down burger, “just a bun, burger and a slice of processed cheese,” in February 2025, and pointed out that the ordering kiosk lets you add bacon. I think Lotteria made the right call. On thin patties, lettuce mostly adds water and turns the bun soggy.

Ingredients for 2 copycat Double Classic Cheeseburgers

For two burgers you need four thin beef patties, four cheese slices, two soft butter buns, mayonnaise, mild mustard, onion and four pickle slices. Patty weight and sauce amounts are my estimates; Lotteria publishes neither.

• Ground beef: 300 g (10.5 oz), 80/20, shaped into 4 patties of 75 g (2.6 oz). My estimate, within a likely range of 70 to 80 g per patty.
• Processed cheddar slices: 4 (American-style melting slices).
• Soft butter buns: 2, brioche-style or potato buns, about 10 cm (4 in) wide.
• Unsalted butter: 15 g (1 tbsp), for toasting the buns.
• Mayonnaise: 30 g (2 tbsp), 1 tbsp per burger.
• Mild yellow mustard: 10 g (2 tsp), 1 tsp per burger.
• White onion: 30 g (about ¼ small onion), finely chopped.
• Dill pickle slices: 4, 2 per burger.
• Fine salt and black pepper: to season the patties.

Lotteria copycat recipe, step by step

The method takes about 25 minutes: 15 minutes of prep, 10 at the stove. Timings and temperatures are my choices. Lotteria has never said how it cooks the patties, on a griddle or a grill, or at what heat.

1. Chop and rinse the onion

Chop the onion as finely as you can, about 3 mm (⅛ in). Soak it in cold water for 10 minutes, then drain it well. The soak takes the harsh edge off raw onion so it doesn’t bury the cheese. It’s the step people skip, and they shouldn’t.

2. Shape the patties

Divide the beef into four 75 g (2.6 oz) portions. Press each into a patty about 11 cm (4.3 in) wide, slightly wider than the bun, since it shrinks as it cooks. Chill the patties for 10 minutes so they hold together in the pan.

3. Toast the butter buns

Melt the butter in a skillet over medium heat. Toast the cut sides of the buns for about 1 minute, until golden. Set them aside, cut side up.

4. Sear the patties

Heat a cast-iron skillet or griddle over high heat to about 220 °C (430 °F). Season the patties with salt and pepper and sear them for 2 minutes. Don’t touch them. If your pan is small, work in two batches.

5. Flip and melt the cheese

Flip each patty and lay a cheese slice on top straight away. Cook for 1 to 2 minutes more, until the cheese slumps over the edges. The center of the patty should reach 71 °C (160 °F), the USDA safe minimum for ground beef, so check with a thermometer.

6. Sauce and assemble

Spread 1 tbsp mayonnaise and 1 tsp mustard on each top bun. Stack two cheese-topped patties on each bottom bun, then add two pickle slices and half the chopped onion. Close and serve at once. The stacking order is my call: secondary sources describe one, but no primary source confirms it.

What this copycat keeps from the original

This copy keeps the four things that define the Korean burger: two patties with cheese melted onto them, the mustard-and-mayo pairing, chopped raw onion with exactly two pickles, and no lettuce. Two Korean sources, Brunch and The Edit, confirm all four.

• Cheese melted onto each patty, not laid on cold, as in Lotteria’s 2016 launch description.
• Mayonnaise plus mild mustard, no ketchup. Lotteria’s mustard sauce is a proprietary formula, so mild yellow mustard is my closest stand-in, at an estimated dose. Resist the ketchup. It turns this into a generic cheeseburger.
• Two pickle slices only. The 2016 Brunch reviewer already found the pickle flavor strong, so I don’t add more.
• A soft, slightly sweet bun, which the same reviewer noticed. A butter brioche gets you there.
• What stays uncertain: patty weight and fat ratio, seasoning, cooking temperature and the exact cheese. I chose them to match the descriptions; they are not Lotteria’s specifications.

Double cheeseburger at home: bun, cheese and pickle tips

A soft brioche or potato bun, processed melting cheddar and thin, sharp dill pickles bring a homemade double cheeseburger closest to Lotteria’s. Get those three right and the rest is detail.

Which bun imitates Lotteria’s butter bun?

A small butter brioche, toasted in butter, is the closest match you can buy. Lotteria hasn’t published what goes into its butter bun, so treat this as an approximation. A potato bun works too, and it nods to the 2016 original.

Which cheese should you use?

Use processed cheddar slices that melt all the way. Lotteria said cheddar in 2016, and the Korea Times describes processed cheese. The brand has never been confirmed. Skip aged cheddar here: it splits and goes greasy before it drapes.

Korean vs Japanese Lotteria: which burger is this?

This recipe copies the South Korean Double Classic Cheeseburger, not a Japanese Lotteria burger. Lotteria Japan’s 絶品チーズバーガー (Zeppin Cheeseburger) used Gouda and red cheddar on a coarse-ground beef patty, as Gigazine reported. Different burger, different country.

Japan has stopped being a reference market for Lotteria anyway. Zensho, which bought Lotteria Japan in 2023, set March 31, 2026, as the deadline to convert every Japanese branch to its Zetteria brand, according to Impress Gourmet Watch. At the end of 2025, Japan still had 106 Lotterias against 172 Zetterias.

Where to eat the original Korean fast food cheeseburger

The surest place to eat the Double Classic Cheeseburger is South Korea, where Lotteria had about 1,300 restaurants in March 2026, according to etoday. In the capital, our Lotteria Seoul guide with menu prices and the 4 a.m. Seoul Station branch tells you where to go, and the best burgers in Seoul hub lists the rest. Our Lotteria Daegu guide with addresses, hours and menu covers the chain’s branches in that city.

Lotteria opened its first US restaurant in Fullerton, California, in early August 2025, Chowhound reports. It also operates in Vietnam (see our Lotteria Da Nang addresses and hours). I have not confirmed that the Double Classic Cheeseburger is sold outside Korea, so check the local menu before you go. For the chain’s history and figures, read our Lotteria brand profile.

Sources and method

I built this recipe from Lotteria’s 2016 launch coverage in Herald Business, the ingredient lists in Brunch and The Edit, the Korea Times, and the product name on Lotteria’s official Lotte Eatz page. The market is South Korea, and I checked the menu in October 2026. Anything those sources don’t state is marked as an estimate.
