Mermaid Crab Sandwiches

Here at Ruffles and Rain Boots, we adore turning every day into fun-times in little ways. Or, turning a party into a silly occasion to really enjoy myself and get a giggle out of the kid. So, of course when she needed (her word, not mine) a mermaid party for herself and a stuffed-animal friend, well, we went to the kitchen to whip-up lunch–er, mermaid crab sandwiches.


They’re the perfect little mermaid party food, if your guests need more than just cake. But it’s also so simple that if you’re just making it for lunch, well, that’s perfect too. If you’re ready to make a fun mermaid crab sandwich, well, let’s get started.

Tips to Make Mermaid Food

  • It’s fine if you know the mermaid you’re making these crab sandwiches for, but if you don’t know your eaters, maybe leave the assembly to them. You can do the heavy lifting of cutting the croissants and even putting in the eyes, but let them choose whether or not to have cheese or condiments or anything else.
  • If you’re more cool than I am, you might think of doing eyes with black olives and mozzarella cheese. But I honestly didn’t think of that until just now. So, there’s that. If you’re not going that direction and want to do what I did, click here to grab the candy eyeballs–it’s a lot faster.
  • To make your crab sandwiches a little easier to handle for little hands, you can use mini-croissants or even bake some of your own–those always bake up smaller than the croissants you get in the bakery.

  3. Place two toothpicks into each croissant at an angle leaning backward. Place a dot of mustard on the back of two candy eyeballs. You will want the toothpicks to be leaning back at a steep angle so the candy eyes laying almost flat so they'll stay there. Then serve! photo collage tutorial of how to make mermaid sandwiches
