Corned Beef Reubens

If you love a sandwich that feels hearty, savory, and absolutely loaded with flavor, these Corned Beef Reubens are exactly the kind of recipe worth making. With slow-braised corned beef, melty Swiss or Havarti, buttery grilled bread, spicy Sriracha slaw, and a creamy Sriracha sauce on the side, this version takes the classic deli-style Reuben and gives it a bold, homemade twist.

This is the kind of sandwich that feels like a full event rather than a quick lunch. The corned beef braises low and slow until fork-tender, then gets sliced thin and piled high onto rye or pumpernickel. Add the grilled bread, warm cheese, crunchy slaw, and a little extra sauce, and you get a sandwich that is rich, tangy, spicy, and deeply satisfying.

It is perfect for weekend cooking, game day, casual entertaining, or anytime you want a sandwich that really shows off.

Why I Love This Recipe

What I love most about this recipe is the corned beef itself. Braising it with onion, spices, ginger, garlic, soy sauce, and brown sugar gives it so much depth that the sandwich feels way beyond ordinary deli meat.

I also love the contrast of textures. The grilled bread is crisp and buttery, the cheese is melted, the corned beef is tender, and the Sriracha slaw brings crunch and brightness that cut through all the richness beautifully.

Another reason this recipe stands out is that it feels like a full sandwich-shop experience at home. It takes a little time, but the result is the kind of sandwich people talk about after the meal is over.

Swaps and Notes

Flat-cut corned beef is a great choice here because it slices neatly for sandwiches once it has cooled slightly. Slicing against the grain is especially important so the meat stays tender.

The bacon, brown sugar, soy sauce, and spice blend give the brisket a deeper, sweeter, more aromatic flavor than a standard boiled corned beef approach.

Swiss is the classic cheese for a Reuben, but Havarti makes a great option if you want something a little creamier and milder.

The Sriracha slaw and sauce bring heat and brightness, which helps balance the richness of the meat and cheese. If you prefer less spice, simply scale the Sriracha down a bit.

How to Make Corned Beef Reubens

1. Prep and sear the corned beef

Preheat your oven to 250°F.

Rinse the corned beef brisket and pat it very dry.

Rub oil over the top and bottom, then sear both sides in a hot cast iron skillet over medium-high heat.

Remove it from the skillet and let it cool slightly.

2. Build the braise

Rub the brown sugar over the fat cap side of the brisket.

Lay bacon strips across the top and secure with toothpicks if needed.

Scatter the quartered onion in the bottom of a 5-quart Dutch oven.

Sprinkle in the cloves, cardamom, juniper berries, star anise, coriander seeds, mustard seeds, black peppercorns, crushed garlic, bay leaf, and crushed ginger.

Place the brisket in the center, bacon side up, and pour the white shoyu soy sauce over the top.

3. Braise

Cover with the heavy lid and place the Dutch oven in the oven.

Cook for about 3 1/2 hours, roughly 1 hour per pound, until a fork slides easily through the center.

Remove from the oven and let the brisket cool enough to handle.

4. Slice the beef

Slice the corned beef very thinly against the grain.

5. Make the Sriracha slaw

Right before serving, combine the cabbage, carrot, and onion in a bowl.

Whisk together the vinegar, sugar, mayonnaise, Sriracha, Dijon mustard, salt, and pepper.

Pour over the vegetables and toss well.

6. Make the Sriracha sauce

Whisk together the Sriracha, Dijon mustard, mayonnaise, salt, sugar, and minced garlic until smooth.

7. Grill the sandwiches

Butter one side of a slice of bread and place it butter-side down in a non-stick pan over medium heat.

Pile on sliced corned beef, then top with Swiss or Havarti.

Add another slice of buttered bread and grill until golden on both sides and the cheese is melted.

Repeat with the remaining sandwiches.

8. Serve

Serve the grilled Reubens with the Sriracha slaw, sweet pickle chips, jarred peppers, and extra Sriracha sauce.

Tips for Success

Let the corned beef rest a bit before slicing so it stays juicy and slices more cleanly.

Slice the meat as thinly as possible for the best sandwich texture.

Keep the sandwich heat at medium rather than too high so the bread gets golden while the cheese has time to melt.

If you are making several sandwiches, keep them warm on a baking sheet in a 200°F oven until ready to serve.

These Reubens are excellent with pickle chips, kettle chips, fries, coleslaw, or a cup of soup. They also work beautifully as part of a casual entertaining spread when you want something hearty and memorable.
