Why We Love This Corned Beef Sandwich
While the Reuben sandwich is a celebrated classic, the simple corned beef sandwich wins hearts with its straightforward ingredients and flexible flavor profile. It’s a go-to for using leftover corned beef and offers a balanced bite of salt, tang, and crunch. This sandwich delivers:
- Big flavor from the sharp bite of mustard and the briny tang of relish and sauerkraut.
- Perfect texture thanks to toasted rye bread and tender, juicy corned beef.
- Customizable ingredients for an endless range of variations—cheese lovers, pickle enthusiasts, and spice fans all have a place here.
- Quick assembly, making it achievable even on busy days or as a convenient leftover makeover.
Ingredients Breakdown
This sandwich is made with just a handful of classic deli items. Each plays an important role in creating authentic flavor and texture:
| Ingredient | Description / Notes |
|---|---|
| Butter (4 Tbsp, softened) | Gives the bread a golden, crispy crust when toasted. Use unsalted to control sodium. |
| Rye Bread (8 slices) | Traditional choice for its hearty flavor, often with a hint of caraway. Choose fresh bakery-style bread for best results. |
| Mustard (1/4 cup) | Cuts through the richness with acidity and spice. Yellow, Dijon, or spicy brown all work well. |
| Relish (1/4 cup) | Pickled zing that brightens the sandwich—a classic sweet relish or dill-based option can be used. |
| Corned Beef (1/2 lb, sliced) | Purchase from your deli counter or use leftovers from homemade corned beef brisket. |
| Sauerkraut (1/2 cup, drained) | Fermented cabbage brings a unique salty-sour punch. Squeeze or drain well for less sogginess. |
Step-by-Step Instructions
Here’s how to bring this timeless sandwich together for an irresistible lunchtime treat:
- Prepare the bread: Lay out your rye slices. Spread softened butter on one side of each piece. Flip each slice and generously spread the unbuttered sides with mustard, followed by a layer of relish.
- Build the sandwich: On four slices, layer the corned beef evenly. Scatter sauerkraut over the corned beef. Cap each with a remaining slice of bread, buttered side out.
- Toast: Heat a medium skillet over medium heat. Add sandwiches (work in batches if needed), cooking 3 minutes per side until the bread is crisp and golden, and the filling is warmed. Firm but gentle pressure with a spatula helps ensure even toasting.
- Serve: Remove from skillet, slice in half, and serve immediately while warm.

Recipe Tips & Variations
Expert Tips for Success
- Drain your sauerkraut well to avoid a soggy sandwich.
- Press lightly with a spatula during toasting for even browning and a compact bite.
- Use fresh bread—stale or overly soft rye can struggle to achieve the right crunch.
- Adjust the heat to prevent burning; moderate heat is best for melting fillings and crisping bread evenly.
Comparing Corned Beef Sandwich vs. Reuben Sandwich
| Feature | Corned Beef Sandwich | Reuben Sandwich |
|---|---|---|
| Bread | Rye | Rye |
| Meat | Corned Beef | Corned Beef |
| Condiments | Mustard, Relish | Russian Dressing |
| Cheese | Optional | Swiss (essential) |
| Sauerkraut | Yes | Yes |
Creative Variations
- Add cheese: Melty Swiss, provolone, or sharp cheddar boosts richness and makes it more like a Reuben.
- Swap spreads: Try Russian dressing, horseradish cream, or thousand island for a twist.
- Caramelized onions: Top your beef with sautéed onions for added sweetness and depth.
- Pickle fans: Layer in dill pickle chips or more relish for extra tart crunch.
- Extra heat: Stir a dollop of sriracha or hot mustard into your condiments if you love spice.
What To Serve with a Corned Beef Sandwich
The classic sandwich + chips combo is always a win, but here are some tasty sides to round out your meal:
- Potato chips or kettle chips for crunch
- Potato salad—creamy or mustard-based
- Coleslaw for fresh, cool crunch
- Smashed roasted potatoes
- Pickles and extra sauerkraut on the side
Storage Recommendations
If you have leftover corned beef or want to prep ahead, follow these storage tips:
- Cooked corned beef: Store in an airtight container in the refrigerator for up to 3-4 days or in the freezer for up to 3 months.
- Assembled sandwiches: Best enjoyed fresh, but you can refrigerate for up to 1 day, then reheat in a skillet. Freeze only the filling—assembled sandwiches lose quality in the freezer.
- Sauerkraut and relish: Keep tightly sealed in the fridge for several weeks.
Frequently Asked Questions (FAQs)
Q: What’s the difference between a Reuben and a corned beef sandwich?
A: Both feature rye bread, corned beef, and sauerkraut, but a classic Reuben adds Swiss cheese and Russian dressing, making it richer and creamier, while the corned beef sandwich keeps it simpler with just mustard and relish.
Q: Can I use a different bread?
A: Traditional rye offers the right balance of flavor and sturdiness, but you can swap in pumpernickel, sourdough, or multigrain if preferred.
Q: Is it necessary to use butter on the outside of the bread?
A: Butter is key for toasting and achieving that golden, crispy crust, but a neutral oil, mayo, or even a dairy-free substitute can work in a pinch.
Q: Can I add cheese?
A: Absolutely! Swiss is a classic choice, but provolone or cheddar also work. Cheese should go directly on the bread before the beef for optimal melting.
Q: How do I keep the sandwich from being soggy?
A: Thoroughly drain the sauerkraut and avoid overloading with wet condiments. Toasting the sandwich helps seal moisture out, too.
Q: What is the best way to reheat a corned beef sandwich?
A: Reheat in a skillet over medium-low heat, pressing lightly until the bread crisps and the insides are heated through. Avoid microwaving, which can make the bread soggy.
Q: Can I make this sandwich ahead?
A: You can prep the fillings and assemble just before toasting for best texture. If storing, wrap tightly and refrigerate, then toast when ready to eat.
Pro Tips
- Use leftover corned beef from holiday meals to save time.
