When I was brainstorming this recipe, I had a bunch of different Halloween deviled eggs ideas come to mind. Like spider deviled eggs, monster deviled eggs, and bloodshot eye deviled eggs!

Then I started to draw inspiration from where I live. Here in Florida, we’re basically in the swamp, or never far from it. And thus, swamp eggs were born. I had a few things in mind when I came up with this recipe.

I knew I wanted crackled eggs because I love the veiny look.

Another thing that was important to me was keeping these dyed deviled eggs naturally dyed. No icky food coloring if we can help it! (In my experiments, I found that blueberries work perfectly for purple deviled eggs and chlorophyll is great at dying the filling green.)

And the last requirement I had was that the deviled egg filling be completely grotesque. Rotten, if you will. Like something that was dredged up from the bottom of a swamp!

Not only do these deviled eggs look absolutely gross (read: perfect for Halloween!), but they’re surprisingly delicious with a creamy garlic and dill deviled filling. Talk about one heck of a Halloween appetizer.

I’m going to walk you through making this easy Halloween deviled eggs recipe with step-by-step photos. Let’s get to it!

The Best Halloween Deviled Eggs – Swamp Eggs!

If you’re wondering how to decorate deviled eggs for Halloween, look no further. These are grossly creepy in the perfect way!

In these sections I explain the ingredients and give substitution ideas. For the full recipe (including ingredient amounts), see the recipe card below.

Purple Dyed Deviled Eggs

purple crackled eggs ingredients
  • Eggs – because friends, you can’t have deviled eggs without the eggs!
  • Frozen blueberries – we use frozen blueberries that are thawed to naturally dye the hardboiled eggs purple. During my testing, I got much better results using frozen blueberries that are thawed than I did using fresh blueberries (their staining power is greatly superior for some reason)
  • Hot water – for the dye solution
  • Distilled white vinegar – vinegar helps the color set on our naturally dyed deviled eggs; if you follow the recipe (don’t let the eggs soak longer), you shouldn’t be able to taste the vinegar

Green Deviled Egg Filling

  • Egg yolks – from the hard-boiled eggs after they’re dyed
  • Mayo – like many deviled egg recipes, Halloween eggs use mayonnaise as the creamy base for the filling
  • Liquid chlorophyll – this is what we use to naturally dye our spooky deviled egg filling green
  • Salt and black pepper – these simple seasonings make sure our deviled eggs aren’t bland
  • Dill and chives – these fresh herbs not only add a ton of flavor, but they also help to cover the slightly grassy taste of chlorophyll; and they bump up the green color too
  • Garlic – don’t skip the garlic! Yes, it’s raw (vampire slayer-style!), but its sharp bite pairs perfectly with the flavor of dill

Other Ingredients

  • Poppy seeds – we use poppy seeds as a garnish on top to look like tiny little spider eggs…ewww, but in the best way!

How to Make Halloween Deviled Eggs

The beauty of this method is that you can also use it to make crackled eggs for Easter, or naturally dyed deviled eggs for any occasion!

How to Make Hard-Boiled Crackled Eggs

  1. Add the eggs to a 3-quart saucepan, and add enough cold water to cover the eggs by 3 inches. Bring the water to a rolling boil over high heat. Immediately reduce the heat to a slow boil and set a timer for 9 minutes 30 seconds.
  2. Once the timer goes off, drain the eggs and add them to a large bowl of ice water. Let the eggs chill in the ice bath for 10 minutes.
  3. Crack the egg shells on each egg in several places, leaving the shell still on the eggs (this is what creates the veiny, crackled look).

How to Make Naturally Dyed Purple Eggs

  1. Add the thawed blueberries, hot water, and vinegar to a blender or food processor and puree.
  2. Add the blueberry mixture and hard-boiled eggs to a gallon-sized zip-top bag, squeeze out as much air as possible, and put the bag into a large bowl. Refrigerate 24 hours, rotating the eggs a few times. (Note that the eggs won’t be fully submerged in liquid; just rotate them a few times and you will get the desired crackled look.)
  3. After 24 hours, use tongs to transfer the eggs to a large baking tray lined with a wire rack. Let the eggs dry on the rack (in the fridge if you have space) for 1 hour. 

How to Make Green-Filled Halloween Deviled Eggs

  1. Use a paper towel to blot any remaining moisture off the egg shells. Peel the eggs, slice each in half lengthwise, and transfer the yolks to a large bowl. 
  2. Mash the egg yolks well, and then add the mayo, chlorophyll, salt, and black pepper and mix thoroughly.
  3. Add the dill, chives, and garlic, and stir until combined.
  4. Pipe or spoon the yolk mixture into the egg whites. Sprinkle the poppy seeds on top, and serve.

Storage and Make Ahead

Normally, deviled eggs last for up to 4 days covered in the fridge. However, these are a little different.

The chlorophyll in our herby deviled egg filling can change color (it has the tendency to darken) and intensify in flavor over time. Because of that, I recommend waiting to add the chlorophyll to the filling within 2 hours of serving these Halloween deviled eggs.

But you can get some of the process made ahead of time! According to the FDA, hard-boiled eggs last up to 7 days in the fridge whether they’re peeled or unpeeled.

Halloween Deviled Eggs FAQs

Can I Use Food Coloring For These Dyed Deviled Eggs?

Yes! If keeping these Halloween eggs naturally dyed isn’t a concern, you can use food coloring.

For the crackled eggs exterior, you can use a combination of blue and red food coloring to make purple (or use black food coloring instead!). And for the filling, use green food coloring.

What is the Best Way to Fill Deviled Eggs?

There are several different methods you can use to filled deviled eggs, depending on the look you’re going for. And you don’t need a piping bag or any special equipment for some of them!

  1. Spoon – Use a regular spoon to simply dollop the filling into the hard-boiled egg whites. This method is a little more rustic (read: sloppy!), but they’ll taste the same.
  2. Scoop – Use a 1-tablespoon scoop to scoop in the filling.
  3. Pipe with a plastic bag – You can use a Ziploc bag as a make-shift piping bag. Add the deviled egg filling to the bag, squeeze out the air, seal the bag, snip off one corner, and pipe the filling.
  4. Pastry bag – Just like piping buttercream onto cakes, you can use a pastry bag fitted with whatever tip you like to fill deviled eggs. This option gives you the most precision for the fanciest looking deviled eggs! (Pro Tip: I like using a disposable piping bag to fill deviled eggs because unlike a reusable pastry bag, you don’t have to worry about getting the garlic flavor out!)

How Long Can I Leave Deviled Eggs Out?

If you’re serving these deviled eggs at a party, note that you can leave them at room temperature for up to 2 hours.
