Halloween is one of those holidays that the whole family gets super excited about. We decorate the house, we plan out our costumes and we just have a great time being silly. I love seeing all of the creative costumes and big smiles on the kids faces as they go trick-or-treating.

Now that my kids are in their teens, they are balancing that line between being a little kid and growing up. I want them to dress up, trick-or-treat and have some fun. I just wish their teachers would let them be kids and give them a night with no homework.

I first published this recipe for Avocado and Wasabi Halloween Deviled Eggs back in 2013. Never in my wildest dreams did I think they would go viral. You might have seen variations or similar creepy green deviled eggs out there, but this is the original. The beauty of the internet is that you can share your ideas with the world, even with those who just want to copy your ideas.

But enough of that. Let’s get to the recipe!

Creepy Halloween Deviled Eggs

The great thing about having older kids, is that you can create some really creepy and gross foods to celebrate Halloween. And they aren’t a scared toddler who won’t eat it! And I am taking full advantage of this milestone.

Now I am not a huge fan of deviled eggs. They are usually full of goopy mayonnaise and don’t have much flavor. I knew I wanted to create some really fun and creepy halloween deviled eggs, and really break the mold of what a deviled egg should be. What could be creepier than green deviled eggs with blue-grey veins all over them??!!

The Best Way to Hard Boil Eggs

But before we get into the green deviled egg filling, we have to start with hard boiled eggs. My kids love eating hard boiled eggs for breakfast. After years of making this super simple food, I’ve found the best technique for making the perfect hard boiled egg.

You start by placing your eggs in a saucepan. Do not overcrowd you pan as the eggs should fit in one layer. Cover the eggs with cold water. and add some salt. Why add salt? Great question!

Adding salt to the water for hard boiled eggs does nothing for flavor. What it does is increase the boiling point of the water. This means that your water will have a higher temperature and your eggs will cook better.

Cover your pot and bring your eggs and water to a boil. Once you get a rolling boil, lower the temperature from high to medium and cook your eggs for 5 minutes. Remove the pot from heat and let the eggs sit in the hot water with the lid on the pot for 10 minutes.

Make sure you have a large bowl filled with ice water ready. After 10 minutes, put your eggs in the cold water until they are cool to touch.

How to Make Spider Web Deviled Eggs

What makes these halloween deviled eggs extra spooky is the spider web effect created on the white part of the egg. To do this, you skip the cold water bath after boiling the eggs. You also add frozen blueberries to the water bath.

I’ve written before about natural food dyes. Remember my naturally dyed Easter eggs? Blueberries give you a nice indigo dye. I find the frozen blueberries give you more juice much more quickly than fresh blueberries. And they are cheaper, too! You can use food coloring to achieve the same effect.

Either way, add it to the hot water bath when you are boiling your eggs. Once the eggs are cooked, you need to remove the eggs and use the back of the spoon to press cracks all over the egg shells. Don’t worry about messing up. All those cracks you form in the egg shells will form indigo lines all over your eggs.


Once the eggs are cracked up, place them back in the blueberry bath water and let it sit for 6 hours or up to overnight. Yes, this extra step takes extra time. But that extra time is so worth the final creepy deviled egg effect!

Creepy Avocado Wasabi Deviled Egg Filling

So your hard boiled eggs are cracked and getting a nice soak in the blueberry water. It is showtime! Peeling eggs can be hit or miss. I found the best way to start peeling the egg is at the rounded end. You can usually find a little air pocket on this end.

As you peel your eggs, your awesome spider webs are revealed. Cut the eggs in half lengthwise and scoop out the yolks. Again, to make the deviled egg filling green, you could easily use food dye.

But I wanted something that tasted good and used zero food dyes. Thanks to my friend, Mimi Avocado, I had a beautiful avocado from her ranch on my counter giving me some serious green inspiration.

This mayo-free deviled egg filling is made with egg yolks, avocados, wasabi and lemon juice. It is a pretty forgiving recipe. You can add more wasabi if you like a lot of POW in your deviled eggs, or tone down the wasabi and add more avocado. I typically add more lemon juice because we love that tangy flavor!

I piped the green egg filling using the infamous grass piping tip (#233) for an extra touch of creepy. I confess that the holes plugged up and I had to stop frequently to unplug the holes. You can also use the open star piping tip, like this one (#1M), to pipe in the creepy green deviled egg filling into your spider web cups.

Topped with charcoal salt and black sesame seeds and my mayhem was done.

Green Halloween Drinks

My freaky green color scheme this Halloween isn’t over. Last week I featured my Toxic Sludge/Kiwano Margarita. It is naturally green from the kiwano fruit. It has a tart, cucumber like flavor and makes a really nice margarita!

Who else is excited for Halloween?!!
