18 Unique Mermaid Party Food Ideas for an Undersea Celebration (2024)

When planning for an upcoming children’s birthday party, the theme is one of the most important parts of the job. Boys might want the Hulk or Mario Party to play a central role…So how about a mermaid party for your little girl and her friends? A mermaid party will need more than costumes, however. How about some mermaid party food ideas to tie it all together? Peerspace is one of the internet’s best resources for party planners; we have ideas by the boatload to help you pull off a mermaid party. Take a look at some of our favorite food ideas!

1. Octopus hot dogs

Popular in Japan for bento lunch boxes, octopus hot dogs are a quick and easy mermaid party food idea to put together! They look adorable and don’t require any special preparation besides cutting each hot dog in half and then splitting the lower end to make the tentacles. Prepare as you normally would in the oven, on the stove, microwaved, or grilled, and the legs will curl in the heat!

2. Treasure pasta shells

Multicolored pasta shells are the perfect treasure shells for a mermaid party! You’ll need to prepare each batch of pasta using a different food dye. We recommend going with 3-4 colors, like red, yellow, green, and blue for a glittering bowl of treasure pasta! Simply boil the pasta as you normally would in salted water and add a few drops of food coloring at the very beginning.

Once your party food is finished you will still need a venue for hosting your kid’s birthday party. That’s where Peerspace comes in! We are the nation’s leading online marketplace for party spaces near you and have hundreds of venues with backyard play areas, movie screens, and other amenities for a mermaid party! 

3. Mermaid cake

If you’d like to try your hand at cake decorating, this mermaid cake recipe is right up your alley! The bright blue frosted scales will create a gorgeous effect that your kids will be delighted with. Moist vanilla cake with buttercream frosting is a classic birthday cake flavor. Add glittering blue sprinkles, candles, and a mermaid’s tail on top to complete the decor!

4. Clamshell cookies

Pretty and easy to make, clamshell cookies are nice little snacks that don’t take much time to prepare. The buttercream frosting is even homemade in this recipe. You’ll need to buy the sugar pearls but the end result is colorful and realistic cookie clams that your kids will gobble up!

How about a no-preparation-required mermaid party food idea? If you’re in a hurry, pick up some gumball pearls for the snack table! These giant pearls can be served as they are or added to gift bags or snack bags to be given out as party favors after a fun game. Just make sure the kids know how to dispose of used gum properly; you don’t want to be finding it for months after the party has ended…

6. Mermaid lemonade

Mermaid party drinks are just as important as the food you serve. Stick to the theme with mermaid lemonade! From the colorful seaweed green and sea blue ice cubes to the vivid blue lemonade itself, this drink is so pretty you won’t want to drink it too quickly. Don’t forget to dip each glass in dyed sanding sugar for the ultimate mermaid party mocktail!

7. Sand dollar cookies

The cinnamon, almond, and butter flavors of these sand dollar sugar cookies will be a guaranteed hit at the party table! Best of all, they are easy for bakers of any skill level to make. All you need to do to have cute sand dollars is to add almond slivers to the tops right before baking! The total prep time required, including chilling before baking, is less than two hours. Perfect for an upcoming mermaid party today!

8. Ocean blue party punch

An ocean blue punch bowl is the perfect drink for a mermaid-themed birthday party! Follow any of the non-alcoholic recipes listed here for a delightful party bowl to which you can add fruit slices and ice. Bonus creativity points if you take the time to make colorful blue and green ice cubes using water with food coloring in it.

9. Ursula cupcakes

What would a Little Mermaid party be without a showing from the star villainess? Bring back the thrill of those movies with some Ursula cupcakes, frosted in black and purple! You’ll need gel food coloring for these rather than a water-based blend. But the recipe is otherwise easy to pull off and a guaranteed hit with the kids!

10. Seaweed chip dip

Actual seaweed isn’t all that tasty to kids but don’t worry, this recipe doesn’t call for any! You’ll simply be using hummus dyed green and seasoned to taste. You can also go with guacamole for the same effect!

11. Pink seashell sugar cookies

Ice cream is one dessert that most people end up buying. But did you know that it doesn’t take all that much to make it yourself?

We’ve already looked at seashell cookies, so how about some seashell donuts instead? Each one is more substantial and chewier than a cookie and can be made as large as you like. We recommend using different frosting colors for each donut; vary things up with white, pink, and blue shells for fun!

17. Honey lime mermaid fruit salad

Fruit salads are a dish that can find a place at any party table. You can simply toss a bunch of mixed fruit together…Or try to make something a little more involved, like this recipe for honey lime mermaid fruit salad! The honey lime drizzle adds an extra bit of sweet tanginess to each bite of soft fruit. To keep to the mermaid theme, you’ll need a mermaid tail cookie cutter to chop the watermelon into the right shapes, like this one!  

18. Mermaid party donuts

Here is a recipe that is so easy even your kids can make them with you! Mermaid party donuts call for pre-made donuts; you can make them yourself but that does add to the preparation time. Simply dip them in colored frosting and sprinkle them with candy shapes like pearls and stars for an instant party favorite.
