This Cod Reuben Sandwich is a fishy take on a classic deli-style Reuben! It's piled high with seared cod, sauerkraut, and a homemade yogurt-based Russian dressing.
Growing up, I didn't spend much time eating Reuben sandwiches.
What I did eat, on a somewhat regular basis, is the Reuben's ever so slightly lighter cousin, the Rachel.
Just like a Reuben, the Rachel is made up of rye bread, Russian dressing, sauerkraut, and Swiss cheese all grilled in sweet, sweet butter. Unlike the Reuben, the Rachel has turkey instead of corned beef.
And this fishy version of the Reuben uses COD instead of corned beef. Maybe we'll call it a Rod.
Yes? No?
How did I get the idea for a seafood Reuben?
I was in Florida for the bestie's wedding, and the restaurant menus were full of seafood sandwiches.
Guys, I love seafood sandwiches! I make smoked fish sliders, slow-roasted salmon sandwiches, and seared salmon sandwiches with Dijon.
But in Florida, I saw the most exciting seafood sandwich ever. I saw-- not once, not twice, but THREE TIMES-- grouper Reubens on restaurant menus.
I shrieked with delight! But then the sandwiches came.
They were good-- but they were definitely not Reubens!
There was no rye bread, there was cole slaw instead of sauerkraut, and there was no Swiss cheese. But these faux-Reubens gave me an idea.
I came home, and started brainstorming.
Best Fish for Seafood Reubens
Yes, grouper is fabulous on sandwiches, but it's not always easy to find. If you can find some, try making my version of a grouper Reuben.
Which type of fish would be thick and delicious, so that the sandwich would have a similar texture and look to a classic Reuben?
Which type of fish would go well with the flavors in the classic-- the rye bread, sauerkraut, and spicy Russian dressing?
The answer to this fish sandwich seemed clear, cod.
If you've got extra cod in your fridge or freezer, check out these recipes too: broiled cod with lemon sauce, spiced cod with sweet potato mash, pumpkin cod curry, and pan-seared cod with bourbon sauce.
What Can I Use Instead of Cod?
If you prefer, you can swap the cod for another dense and meaty white fish.
Can I Skip the Cheese on a Cod Reuben?
Yes-- if you want to.
But it's really delicious with the cheese!
Should I Use Sauerkraut or Cole Slaw?
I tried versions with cole slaw instead of sauerkraut, just in case all those Florida cafes were onto something-- they weren't.
Use sauerkraut! I like to use homemade sauerkraut (but store-bought works too!).
It's delicious with the cod.
Can I Use Pre-Made Dressing?
This recipe includes a quick and easy, healthy yogurt-based Russian dressing.
But if you're in a hurry, a pre-made Russian dressing (if you can find one!), or a Thousand Island will work just fine.
Russian dressing is spicier than Thousand Island.
How to Make a Cod Reuben Sandwich
To make a Cod Reuben Sandwich, make the dressing first.
You could even make the dressing the day before!
Next, sear the cod, and then assemble your sandwiches.
Add the rye bread, and layer it with sauerkraut, as much of the dressing as you want, the cheese (if you're using it), and of course-- the cod. If your cod isn't the same size as the bread, you can flake it apart a little and spread it out.

Next, add a little more butter to the pan, and quickly grill each side of the sandwich.
Grab some napkins and eat your Cod Reuben Sandwich while it's still hot! Then, sigh happily after enjoying your giant deli sandwich!
Cod Reuben
Ingredients
Russian Yogurt Sauce:
- ½ cup whole milk plain yogurt
- 2 green onions, diced
- ⅛ cup diced red onion
- 1 tablespoon relish (dill or sweet)
- 1 tablespoon horseradish root, freshly grated (or sub prepared)
- 1 teaspoon tomato paste
- ½ teaspoon salt
- ½ teaspoon paprika or smoked paprika
Cod:
- 2 cod fillets (~4oz each)
- ¼ teaspoon salt
- 1 tablespoon olive oil
- 1 tablespoon butter
Reuben:
- 4 slices rye bread Jewish rye preferred
- ½ cup sauerkraut
- 2 slices Swiss cheese (optional), add more if desired
- 1 tablespoon butter
Instructions
Prepare Toppings:
- Combine all ingredients for Russian dressing. Taste dressing, add more salt if it tastes bland, and/or more horseradish if you prefer it spicier. Set aside.
Cook Cod:
- Add oil to a heavy pan, such as cast iron, and heat on medium-high heat. Pat cod dry, and then dry it off again. Wet fish will stick to the pan.
- Set cod in hot pan, and DO NOT TOUCH IT. Set a timer for 4 minutes, and don't touch the cod until the timer goes off. (If your butter smokes a little, lower the heat slightly.)
- Next, use a thin metal spatula to flip the cod. If it sticks to the pan, wait another 30 seconds. The fish will release when it's done cooking. Cook for another 4 minutes, and remove from pan.
Grill Sandwiches:
- Lower the heat to medium.
- Prepare sandwiches by layering one slice of bread, a thick layer of the Russian sauce, sauerkraut, the cod, cheese, and another piece of bread. If the cod is too small for the bread, you can flake it apart with a fork and spread it across the bread.
- Add remaining butter to the pan, and grill sandwiches about 2 minutes per side, until each side is golden and the cheese is melted. Serve immediately.

My mouth is absolutely watering just looking at this sandwich. Like you, I stopped buying lunchmeats a long time ago -- if I want a sandwich, I use leftover meat from whatever we had last night -- but I've never thought to make fish sammies with cod -- and I usually have cod in the house... Pairing the cod with sauerkraut and dressing -- just sounds heavenly. I'm not a seafood/cheese hater, either -- so I'll add a few slices to increase the nummi-ness factor!

Yay for skipping the lunch meats! So many preservatives!! Let me know if you try this out (and I really recommend the cheesy version!!!)

OMG - I love this Sarah! What a neat idea using cod! I do love a reuben sandwich, but haven't had in forever! This sounds a lot lighter and definitely a delicious lunch or supper. That yogurt sauce sounds pretty yummy too - bet it would be awesome for fries 😉

Thanks Dawn!!! It's definitely lighter than a regular Reuben (and so yummy!) Enjoy!

Never would have thought to use fish in a reuben sandwich! This looks really delicious
Shelley Blechar
Delish! I have always been more of a Rachel fan myself. I never would have thought to sub cod! I think the dressing is the integral part. In college I'd go to McDonald's and get a Big Mac....with no meat. Tasted almost the same LOL! When I think of coleslaw on a sandwich I think of a cold sandwich. A grilled reuben def calls for kraut!
Donna
Those photos have me craving this right now. Like I really need it right now. Love the sound of that Russian yogurt sauce, and everything else about this sandwich. Adding it to the menu plan for this week, I am excited to try it out 🙂

So, I've been following this delicious looking sandwich on social media, and it needs to happen in my life ASAP. I absolutely love the substitution of cod for a lighter twist on a classic, and your yogurt Russian dressing sounds on point! Also, I had to laugh about breaking the "no cheese with fish" rule. This was kind of engrained in me growing up, and I've become a bit of a rebel in my adult life. 🙂 Some fish dishes really do benefit from cheese!
champagne-tastes
Aw thanks!!! And yes- break the rules with me and put the cheese on the fish!!! LOL

We made this tonight and it was amazing! The sauerkraut, the yogurt dressing, and the fish were absolutely perfect together, and since I don't actually go for sauerkraut very often, for me that's really saying something. 🙂 We had some pumpernickel bread on hand, so we used that and it was A+. Will definitely make again.

Excellent recipe will be making this again.
