Ingredient Spotlight

Gochujang (Korean chili paste)

A thick, fermented Korean chili paste made from gochugaru (Korean red pepper flakes), glutinous rice, fermented soybeans and salt; it’s sweet, spicy and deeply umami with a mild fermented tang. It’s central to Korean cooking (think bibimbap, tteokbokki, marinades) and is sold in tubs at Asian markets, many supermarkets, or online. For a substitute, stir together miso or red bean paste with a chili paste (sambal oelek or sriracha) and a little brown sugar or honey to approximate the sweet-umami heat, adjusting to taste.

Ingredient Spotlight

Sesame oil

Usually refers to toasted sesame oil in this context — a strongly aromatic oil pressed from toasted sesame seeds used as a finishing or flavoring oil in East Asian and Middle Eastern cuisines; it has an intense nutty, toasted aroma and you only need small amounts. You can find it in the Asian/international aisle of most supermarkets or at any Asian grocery. As a substitute, use a very small amount of toasted sesame seeds or tahini thinned with a neutral oil, or mix a neutral oil with just a drop or two of toasted sesame oil to mimic the flavor without overpowering the dish.

Jake's note

"This recipe brings the sticky-sweet, savory notes of bulgogi to the high-heat crunch of a smash burger — perfect for weekend barbecues or an elevated weeknight dinner. Expect fast cook times and big, craveable flavors."

Bulgogi Smash Burger

This Bulgogi Smash Burger takes two simple pleasures — the ultra-crispy, lace-edged smash patty and the sweet-spicy umami punch of Korean bulgogi — and joins them where they make the most sense: at high heat. The trick is in the sequence: a violent first sear to build deep caramelization on 80/20 beef, then a quick hit of a gochujang-soy glaze so the sugars and chili paste caramelize into a sticky sheen without steaming the meat. The result is thin, almost lacey edges with a glossy, savory-sweet top and the bright, oniony finish of fresh scallions.

This version is built for weeknights and backyard sessions where speed and maximum flavor matter. You don’t need a long marinade to get bulgogi character — the glaze concentrates those classic flavors and keeps the patties tender because the meat itself is barely handled and cooked fast. Use a soft, slightly sweet bun (brioche or potato) to sop up glaze, consider a double-stack for extra heft, and serve immediately so the contrast between crisp edges and molten cheese is intact.

Instructions

Make the bulgogi glaze

Whisk together soy sauce, gochujang, brown sugar, sesame oil, minced garlic and half the sliced green onions in a small bowl. Transfer to a small saucepan over medium-low heat and cook, stirring, until the sugar dissolves and the sauce thickens slightly, about 2–3 minutes; remove from heat and set aside.

For this step

2 tbspSoy sauce
2 tbspGochujang (Korean chili paste)
1 tbspBrown sugar
1 tspSesame oil
2 cloveGarlic, minced
2 stalkGreen onions, thinly sliced

Portion the beef

Divide the ground beef into four equal 4-oz (about 115 g) balls, handling as little as possible to keep the meat tender. Keep the balls loosely packed and chilled until the griddle is ready.

For this step

1 lbGround beef (80/20)

Preheat and smash

Heat a large cast-iron skillet or flat top griddle over high heat until smoking hot, then add the vegetable oil and spread to coat. Place a beef ball on the hot surface, immediately press down hard with a heavy spatula or burger press to form a thin patty, and hold for 10–12 seconds; cook until deeply browned at the edges, about 2 minutes.

For this step

1 tbspVegetable oil (for griddle)
4 sliceCheese slices (American or cheddar)

Flip, glaze and melt cheese

Flip each patty and quickly brush the hot top with the bulgogi glaze, letting it caramelize onto the meat. Top each patty with a cheese slice, close to the heat for 30–45 seconds more until the cheese melts and the glaze becomes sticky.

Toast the buns

While patties finish, place buns cut-side down on the griddle and toast for 20–30 seconds until lightly golden. Remove buns and keep warm.

For this step

4 countBurger buns

Assemble and garnish

Build each burger with the toasted bottom bun, a glazed cheeseburger patty (or stack two thin patties if you like), a sprinkle of the remaining sliced green onions, and the top bun. Serve hot and enjoy immediately for best texture and flavor.

Tips from the kitchen

Keep balls loosely packed

Handle the ground beef as little as possible and form loose 4-ounce balls so the patties remain tender despite aggressive smashing.

Get the griddle screaming

Heat your skillet or flat top until smoking hot before adding oil — that immediate contact is what creates the crispy, browned edges.

Press, then hold pressure

Press each ball hard and hold the spatula down for 10–12 seconds to force maximum contact; this is what makes a true smash crust.

Brush glaze after flipping

Apply the bulgogi glaze to the hot side after the first flip so the sugars caramelize quickly without burning during the initial sear.

Melt cheese with cover

Cover the patties or use a metal bowl for 30–45 seconds to trap heat and melt the cheese evenly without overcooking the meat.

Variations & substitutions

Double-stack burger

Cook two thin patties per sandwich and place cheese between them to create an oozy, layered melt that echoes Korean stacked banchan sandwiches.

Bulgogi-marinated beef

For deeper infusion, mix half the glaze into the beef and marinate briefly (30 minutes to overnight); reduce added sugar when searing to prevent excessive burning.

Vegan/plant-based option

Use a chilled plant-based ground (or finely chopped king oyster mushrooms for texture) and swap cheese and buns for vegan versions; the glaze is vegan if your gochujang and sugar are vegan-friendly.

Kimchi-topped twist

Add a spoonful of chopped, drained kimchi or quick pickled cucumbers for tang and texture that cut the glaze’s sweetness beautifully.

Low-sodium or gluten-free

Use tamari or coconut aminos for a gluten-free/low-sodium soy substitute, and verify gochujang is gluten-free or swap a mix of chili paste and miso.

Storage & make-ahead

Store leftover cooked patties and buns separately in airtight containers in the refrigerator for up to 3 days; keep the glaze refrigerated in a small jar for up to a week. To reheat, crisp the patties gently in a hot skillet for 1–2 minutes per side and warm the glaze in a small pan to brush back on, or finish briefly under a hot broiler to re-melt cheese; avoid microwaving which will soften the crust.

What to serve with it

Serve with crisp, vinegary sides to balance the glaze—think a sesame-kimchi slaw, quick cucumber pickles, or fries tossed with Korean chili salt (gochugaru and sea salt). For drinks, a clean, effervescent lager or a citrus-forward IPA cuts through the richness, while soju or a chilled dry sake complements the sweet-spicy notes.

Frequently asked questions

Can I mix the glaze into the meat instead of brushing it?

You can add a small portion of the glaze to the meat for more integrated flavor, but too much sugar in the mix will cause excess sticking and burning on the griddle; brushing after the first sear gives better texture and controlled caramelization.

How can I reduce the heat if gochujang is too spicy?

Cut the gochujang amount in half and balance with a touch more brown sugar or mirin for sweetness, or dilute the glaze slightly with a splash of water or rice vinegar to mellow the heat.

What if I only have lean ground beef?

Lean beef can be used, but expect fewer crispy juices and a drier patty; add a tablespoon of neutral oil or finely grated pork fat to the mix, or cook slightly less to preserve juiciness.

Why are my edges not crispy enough?

Likely your griddle wasn't hot enough, you pressed too gently, or the patties were too thick—ensure a smoking-hot surface, press firmly and thinly, and keep the patties small and flat for the classic lacey crust.

Can I make these ahead for a party?

You can form and chill the meat balls a few hours ahead and keep the glaze refrigerated; however, smash and cook the patties just before serving for best texture and to preserve the crisp edges.
