Grouper Reuben

This grouper Reuben sandwich is a fishy take on a classic deli-style Reuben! It’s piled high with broiled grouper, sauerkraut, and a homemade yogurt-based Russian dressing.

Have you been cooking at home more than usual?

I have been.

And guys, when you’re cooking dinner every single day, it can get a little bit boring.

To help battle dinner-time boredom, I’ve been trying to include a few make-at-home versions of my favorite restaurant meals.

If you follow my Instagram stories, you’ve probably seen some of my DIY take-out meals make recurring appearances. We’ve been eating these deconstructed sushi bowls on repeat.

One of my restaurant favorites is a fish Reuben. It’s just like a classic Deli-style Reuben, but with fish instead of corned beef.

I love making cod Reubens, because cod is easy to find locally, but my first fish Reuben was at a seaside Florida café and included (you guessed it) grouper.

This grouper Reuben is an easy seafood sandwich that will make you feel like you’re enjoying a fish sandwich at the beach. Sand and sunburn not included.

What Does Grouper Taste Like?

Grouper is a mild, meaty, dense white fish.

This fish plays nice with the strong flavors in the Reuben, such as sauerkraut and Russian dressing.

What Can I Use Instead of Grouper?

Can’t find grouper?

Swap another dense or flaky white fish, such as cod.

Sauerkraut or Coleslaw for a Grouper Reuben?

When I see fish Reubens on restaurant menus, they’re often served with coleslaw instead of the traditional sauerkraut.

I’ve tried this sandwich both ways and definitely prefer the sauerkraut version, especially when I can use my homemade sauerkraut. That said, if you’re not into kraut, feel free to swap slaw.

Can I Use Thousand Island Instead of Russian Dressing?

You can, but know that they’re not the same thing.

Thousand Island dressing is sweet and Russian dressing is spicy.

How to Cook the Grouper

I like to broil the grouper for this sandwich because it’s a quick, hands-off method.

Simply brush the fish with oil, sprinkle with a little salt, and place it in an oven-safe pan. I use this Lodge 12″ carbon steel skillet.

Cook the grouper under a broiler for about nine minutes per inch of thickness until it’s tender and opaque.

Assemble the Grouper Reubens

After the fish is cooked, make the sandwiches.

Layer Russian dressing, sauerkraut, grouper, and Swiss cheese onto rye bread.

Grilling Grouper Reubens

Next, melt butter in a hot pan. I simply wipe out the pan I used to cook the fish and reuse it now.

Add the sandwiches to the pan and cook for about two minutes per side, until the bread is toasted and the cheese is melted.

Serve your grouper Reubens right away along with some crispy oven fries and a dill pickle.
