Kimchi Reuben Sandwich Recipe
Upgrade the classic deli sandwich with a vibrant, spicy twist. This Kimchi Reuben features tender corned beef, melted Swiss cheese, and tangy fermented kimchi toasted to crispy perfection on rye bread.
- Fermented lactic acid in kimchi cuts through the heavy fat of corned beef and Swiss cheese more dynamically than traditional sauerkraut.
- Squeezing excess moisture from the kimchi prevents steam buildup, ensuring a perfectly crispy, golden-brown crust.
- A custom Gochujang-infused Russian dressing bridges the gap between Eastern heat and Western savory elements.
The secret to an exceptional Kimchi Reuben Sandwich lies in managing moisture and balancing heavy fats with sharp, fermented acidity. While a traditional Reuben relies on sauerkraut, substituting it with well-fermented napa cabbage kimchi introduces complex lactic acid, garlic, and ginger notes that slice through the richness of corned beef.
Excess water is the enemy of a crispy melt.
When wet kimchi hits a hot skillet, the water rapidly converts to steam, which gets trapped beneath the bread and turns the crumb soggy. To prevent this, you must thoroughly press the kimchi in a clean kitchen towel to expel its liquid before assembly. This step concentrates the natural sugars in the cabbage, allowing them to undergo rapid caramelization when toasted, which enhances the sandwich's overall savory profile.
If you appreciate this style of fusion comfort food, you will also enjoy our Banh Mi Grilled Cheese, which similarly balances rich dairy with bright, pickled vegetables.
Choosing the right cheese is equally critical to the structural integrity of the sandwich. Swiss cheese, specifically Emmental or Gruyère, is preferred because its high moisture-to-fat ratio allows it to melt smoothly into a cohesive protein matrix that binds the corned beef and kimchi together.
For those who love these classic deli flavors but prefer a comforting bowl of warm broth, our hearty Reuben Soup offers a brilliant liquid interpretation of these exact ingredients.

It details how to manage ingredient moisture to prevent soggy bread, a principle that applies directly to handling wet kimchi. Applying these thermal principles guarantees a crisp exterior every time.
Precision yields perfection.
Kimchi Reuben Sandwich
Ingredients
- 4 slices rye bread (preferably marble rye)
- 6 oz thinly sliced corned beef
- 1 cup well-fermented napa cabbage kimchi, drained and chopped
- 4 slices Swiss cheese (such as Emmental)
- 2 tbsp unsalted butter, softened (such as Kerrygold)
- 2 tbsp mayonnaise (such as Duke's)
- 1 tbsp ketchup
- 1 tsp Gochujang (Korean chili paste)
- 1/2 tsp fresh lemon juice
Directions
- In a small bowl, whisk together the mayonnaise, ketchup, Gochujang, and lemon juice until smooth to create the spicy Russian dressing.
- Place the chopped kimchi into a clean kitchen towel or paper towels and squeeze firmly over the sink to remove as much moisture as possible.
- Spread a thin, even layer of softened butter on one side of each slice of rye bread.
- Flip the bread slices over and spread the prepared Gochujang dressing on the unbuttered sides.
- Layer one slice of Swiss cheese, half of the corned beef, the squeezed kimchi, and a second slice of Swiss cheese onto two of the bread slices, then top with the remaining bread slices, buttered side facing outward.
- Heat a heavy cast-iron skillet over medium-low heat to ensure even heat distribution and high thermal mass.
- Place the sandwiches in the skillet and cook for 3 to 4 minutes per side, pressing down gently with a spatula, until the bread is deeply golden brown and the cheese is fully melted.
Notes
The single most critical rule for a perfect griddled sandwich is maintaining a low, steady heat source to melt the cheese before the bread burns.
- We recommend using Diamond Crystal kosher salt if seasoning your homemade kimchi; if using fine table salt, reduce the volume by half to avoid over-salting.
- Lactic acid fermentation in the kimchi lowers its pH, which not only preserves the cabbage but also creates a sharp contrast that chemically breaks down the perception of heavy fats on your palate.
- If you skip squeezing the kimchi, the excess water will pool on the bread, causing starch retrogradation to fail and leaving you with a soggy, structurally compromised sandwich. Prevent this by pressing the cabbage thoroughly.
- Leftover assembled sandwiches do not store well; the bread will absorb moisture from the kimchi within 24 hours in the fridge, resulting in a mushy texture that cannot be restored to its original crispness.
- If you do not own a cast-iron skillet, a heavy stainless steel pan works as a backup, though you may need to reduce the heat slightly to prevent the butter from burning due to faster heat conduction.
Serving Suggestions
Serve this sandwich immediately while hot to maximize the contrast between the crispy toasted rye and the gooey melted cheese. Pair it with sides that offer sharp acidity or dry crunch to balance the rich, savory profile of the griddled meat.
- A side of crisp dill pickles (the sharp acetic acid complements the lactic acid of the kimchi).
- Thick-cut potato chips (adds a satisfying, dry crunch to contrast the tender corned beef).
- A light, vinegar-based coleslaw (cleanses the palate between rich bites).
- A cold, hoppy IPA (the bitterness cuts through the fatty profile of the Swiss cheese and butter).
Storage and Reheating
Store any leftover un-assembled components separately. Keep the sliced corned beef and Swiss cheese in airtight containers in the coldest zone of your refrigerator for up to 4 days.
Do not freeze assembled sandwiches. The high water content in the kimchi and the delicate emulsion of the dressing will break upon thawing, leading to a watery, unpalatable mess.
To reheat an assembled sandwich, place it in an oven or toaster oven preheated to 350°F (175°C) for 8 to 10 minutes. This dry heat evaporates surface moisture and crisps the bread while gently melting the cheese.
Avoid the microwave entirely. Microwaving heats water molecules rapidly, steaming the bread from the inside out and turning the crust rubbery.
Ingredient Substitutes
You can easily adapt this recipe to suit dietary preferences or ingredient availability with minor technical adjustments.
- Corned beef to pastrami: Swap at a 1:1 ratio. Pastrami is more heavily spiced, so reduce the Gochujang in the dressing slightly to keep the flavors balanced.
- Rye bread to sourdough: Swap at a 1:1 ratio. Sourdough has a tighter crumb, which may require an extra minute of cooking time to allow heat to penetrate to the cheese.
- Swiss cheese to Provolone: Swap at a 1:1 ratio. Provolone melts at a slightly lower temperature, so monitor the skillet closely to prevent the cheese from running out before the bread toasts.
Mastering the balance of moisture and heat transforms this simple melt into a restaurant-quality experience. Keep your skillet low, squeeze your cabbage thoroughly, and enjoy the complex interplay of spice, fat, and acid.
