This Swedish inspired seafood sandwich cake (smörgåstårta) is a show stopping centerpiece that will raise the bar at your next special event or celebration.

seafood sandwich cake smörgåstårta presentation

This is one epic sandwich.

There’s a few steps to the planning and preparation, but it’s worth it!

And, when you stop to think about it – it’s actually a lot simpler to make than it seems.

It’s perfect for special occasions.

We love it on holidays like New Year’s Eve and Easter as well as for Mother’s day, baptisms and birthdays, or for a memorable brunch.

I remember my first smörgåstårta as if it were yesterday.

It was my first time in Sweden, and having never seen anything like it before, I was a little skeptical. All of that cream and cheese?

My first bite was interesting. Then the second. By the third bite, I was convinced. This is the best thing ever.

After an amazing smörgåstårta dinner, I was informed – if you thought that was good, just wait until tomorrow.

It’s even better the next day.

The bread has time to absorb the cream and really let the flavors come together.

You can even have it for breakfast if you want to.

And I came to realize that, of course you’ll have it for breakfast, because it’s impossible to think of any other food when there’s smörgåstårta leftovers in your fridge.

That’s just a fact.

But wait a minute, it is a lot of cream and cheese right? Isn’t that way too heavy?

You know what?

We love to make these homemade sandwich cakes so often that we’ve actually found a way to lighten them up.

Instead of heavy cream or mayo, we use mostly Turkish labneh (tangy yogurt with a texture similar to cream cheese) and a little sour cream. That reduces the fat and calories by a long shot.

And with the creamiest consistency, it tastes like it would be worse for you, when it’s actually a lot healthier. How about that?

But what about all those carbs? That’s a ton of carbs.

Well, not if you use a low carb bread like Carbonaut. That’s what we do in this recipe. Our homemade smörgåstårta is actually made of a low carb, gluten free bread.

So basically, you can indulge in perhaps the richest, creamiest sandwich cake you’ve ever tasted, and rest assured that it’s lower in carbs, calories, gluten and fat.

Ingredients in Seafood Sandwich Cake (Smörgåstårta)

seafood sandwich cake smörgåstårta ingredients mise en place
  • Bread — you can use your bread of choice, our seafood sandwich cake is made with low carb and gluten free Carbonaut bread.
  • Labneh — a thick yogurt cheese with flavor and texture similar to cream cheese.
  • Sour Cream — use full fat, not light or fat free.
  • Mustard — we love honey mustard in this sandwich cake.
  • Sandwich Fillings (choose your favorite four):
  • Cheese slices — we use Havarti cheese for the sides of the sandwich cake.
  • Smoked Salmon — for garnish on top of the cake.
  • Optional Garnishes — Feel free to choose your favorites from the following:
    • radish
    • dill
    • chives
    • cucumber
    • lemon
    • red onions
    • grapes

Although we have shown five sandwich fillings above, we use four layers in our smörgåstårta, so you only need four fillings.

If you want to add a fifth layer and use them all you definitely can, you’ll just need more bread for an additional layer. Likewise, you can choose three fillings for a three layer sandwich cake.

You can choose your sandwich fillings and prep them ahead the night before you need them. That will make things so much easier.

The next day, when those are done, all you have to do is assemble and garnish.

We chose to put tuna salad on the bottom layer, egg salad on the second layer, smoked salmon on the third layer and ended with shrimp salad on top. You can choose any order you like.

How to Garnish Your Seafood Sandwich Cake

Garnishing a sandwich cake is kind of an art form.

We never know exactly how it will go and the design is different each time.

As you can see from our mise en place pictured above, we had planned to use grapes but then left them out because the smörgåstårta was so full already.

You can decorate your sandwich cake in endless ways, it’s totally up to you.

We try to keep our design symmetrical for the most impressive presentation. Plus, that way each slice has the same toppings when cut.

But you can choose your favorite toppings and let your creativity run wild!

Health Benefits of Seafood Sandwich Cake Smörgåstårta

We use labneh and sour cream instead of creme fraiche and mayo for a sandwich cake lower in calories and fat. In our recipe, low carb, gluten free Carbonaut bread takes the place of regular loaves.

This cake is loaded with seafood, eggs, cheese, yogurt and vegetables and is naturally a cornucopia of vitamins and minerals. It’s bursting with nutrients and contains zinc, protein, iron and vitamin B12.

What to Serve With Seafood Sandwich Cake

This is a hearty cake. You won’t need much more food to go with. It’s quite rich on its own and is usually the star of the show.

There are a lot of ingredients, and they combine beautifully for a special occasion.

If you like, you can serve pita pizzas as an appetizer. Two pita pizzas are a perfect amount for four people. We often choose seafood pita pizzas with our seafood sandwich cakes.

Here are our favorites to serve with a seafood smörgåstårta:

These pita pizzas are festive, and have a restaurant style flair to them, while being super easy to prepare!

Serve with sparkling apple or pear cider, non-alcoholic or with alcohol.

Sandwich Cake Charcuterie or Smörgåsbord Tips

If you don’t want to assemble the whole cake, you can serve it as a smörgåsbord (sandwich table), or as we like to call it, a smörgåstårta-bord.

Set it all up as a sandwich cake charcuterie board. Lay out all of the ingredients and provide several plates as well as cutlery.

Basically, you’ll need what you see in our ingredient mise en place photo above. Plus, any additional sandwich fillings or toppings you’d like to include.

Keep the different sandwich fillings in bowls, but you can arrange the rest of the ingredients (cheese, vegetables, bread, grapes, etc.) on nice charcuterie style wooden serving trays.

Let your guests make their own individual mini sandwich cakes or smörgåsår (open faced sandwiches).

This is perfect concept for when you can’t decide on a seafood or meat smörgåstårta.

You can include ingredients for both types and then build your own sandwiches according to individual preferences.

Storage Tips

We like to assemble our sandwich cakes directly onto a serving platter that is just slightly larger than the cake itself. The cake looks great on it, is easy to store in the fridge, and takes up the least amount of space.

Alternatively, if you don’t have a flat rectangular serving platter, you can assemble your sandwich cake right onto a cake storage container with lid.

We have a Wilton Cake Caddy with a lid that snaps on securely. We usually make ours right on the base and then we can easily cover and transfer to the fridge. It does take up a lot of space though, so use it only if you don’t mind that.

It’s super easy to get the leftovers that way, and return to the fridge again. You won’t have to deal with any cling wrap that way. But it’s not as presentable as on a serving platter. When we make sandwich cakes for our own family, we don’t mind using the cake caddy.

This seafood sandwich cake will keep in the fridge for three days, but is best enjoyed within a day or two, for freshest flavor.
