Chef’s note
Rye, Swiss on both slices, thin-sliced corned beef, well-drained sauerkraut and Thousand Island, built ahead the way I did it for the lunch rush: assembled, wrapped tight and held cold, then grilled on a buttered flat-top until both sides are golden and the cheese has melted.

Makes
1 sandwich
Prep time
5 minutes
Grill time
About 3 minutes per side, at serving
Keeps
Up to 2 days, wrapped and refrigerated
Ingredients
- 2 slices rye bread
- 2 slices Swiss cheese (about ¾ ounce each, 1½ ounces total)
- 4 ounces sliced corned beef, trimmed of fat, sliced as thin as possible against the grain
- 3 ounces sauerkraut (drained well, squeezed dry)
- 1 tablespoon Thousand Island Dressing
To grill
- Butter, for the flat-top or griddle
Instructions
- Trim and slice the corned beef. Trim off all visible fat. Slice as thin as possible AGAINST the grain. (Look for the muscle-fiber direction; cut perpendicular to it.)
- Lay out rye bread. 2 slices per sandwich.
- Cheese on each slice. Place 1 slice of Swiss cheese on each piece of bread. (This locks the cheese against the bread for even melting.)
- Layer the corned beef. Spread 4 ounces of corned beef evenly on top of the Swiss on the bottom slice.
- Sauerkraut. Spread 3 ounces of (well-drained) sauerkraut evenly on top of the corned beef.
- Dressing. Spread 1 tablespoon of Thousand Island dressing on top of the sauerkraut.
- Top. Place the second slice of bread (cheese-side down) on top of the dressing.
- Wrap. Wrap the entire sandwich tightly in plastic film.
- Day-dot. Date and label.
- Refrigerate. Use within 2 days.
- To serve, grill on a buttered flat-top until both sides are golden and the cheese has melted (about 3 minutes per side).
Chef’s Tips
- Slice the corned beef AGAINST the grain. This is the difference between tender and chewy. Look at the muscle fibers; cut perpendicular.
- Cheese on BOTH bread slices. This is the trick — Swiss locks against the bread on both sides, sealing the bread from the wet sauerkraut.
- Drain the sauerkraut HARD. Wet sauerkraut = soggy bread. Squeeze in a kitchen towel before adding.
- Thousand Island, not Russian. My choice. Russian dressing is a substitute but the sweet-tang of Thousand Island works better here.
- 2 days max. Pre-built sandwiches, especially ones with wet ingredients (sauerkraut, dressing), don’t last long. Build a fresh batch every other morning.
- Variations: sub corned beef for pastrami (Rachel Reuben); sub coleslaw for sauerkraut (Rachel-style); sub grilled chicken for corned beef; sub Swiss for Gruyere; add 2 tablespoons caramelized onions on top of the corned beef.
- Scaling note: scales by sandwich. Build 8 to 12 in a session for a lunch run.
Storage & Make-Ahead
- Pre-built keeps 2 days in the fridge in tight plastic wrap.
- Don’t freeze — bread goes off.
The dressing
Thousand Island Dressing
The classic — beige, with visible flecks of sweet pickle relish and chopped hard-boiled egg. Built on mayonnaise and chili sauce, with horseradish and Worcestershire for backbone. Make it ahead; it keeps 5 days.
Makes
About 1½ cups
Prep time
10 minutes
Chill time
30 minutes (recommended)
Ingredients
- 1 cup mayonnaise
- 2 tablespoons horseradish (drained)
- ⅓ cup sweet pickle relish (drained)
- 3 tablespoons chili sauce (Heinz or similar)
- 3 tablespoons ketchup
- 1 teaspoon Worcestershire sauce
- 2 tablespoons hard-boiled egg, chopped ½-inch (about ½ a large egg)
- ¼ teaspoon kosher salt
Instructions
- Combine mayonnaise, horseradish, sweet pickle relish, chili sauce, ketchup, and Worcestershire in a medium bowl. Whisk until uniform — you want a beige-pink color.
- Fold in the egg. Add the chopped hard-boiled egg and salt. Stir gently with a spatula — don’t blend; you want visible egg pieces.
- Chill 30 minutes before using. The flavors come together as it sits.
Chef’s Tips
- Drain the relish. Wet relish makes a watery dressing. Press it in a strainer or pat dry with paper towels.
- The hard-boiled egg is what makes it look like the real thing. Chop it small but visible.
- Variations: add 1 tablespoon minced onion; add 1 teaspoon paprika for a smokier color; finish with a dash of Tabasco for heat.
- Scaling note: halves cleanly for ¾ cup; doubles cleanly.
Storage & Make-Ahead
- Keeps 5 days in the fridge in a covered jar.
- Doesn’t freeze.
