How to Make Web-tastic Spooky Bites
Start with peeled hard-boiled eggs. Cut them in half, then remove the yolks. Mash the yolks with avocado, mayonnaise, mustard, salt, and pepper.
Add blue food coloring until the filling has the color you like. Spoon or pipe the filling into the egg whites. Finish each egg with black olive pieces shaped like small spiders.

How to Serve Web-tastic Spooky Bites
Serve these eggs cold on a dark platter for a spooky look. You can add lettuce, parsley, or shredded cabbage around the eggs to make the spiders stand out.
They pair well with fresh vegetables, crackers, cheese, and other Halloween finger foods. Keep them chilled until it is time to eat.
How to Store Web-tastic Spooky Bites
Place leftover eggs in an airtight container. Store them in the refrigerator for up to 2 days.
For the best look, keep the olive spiders on top and avoid stacking the eggs. Do not leave the eggs at room temperature for more than 2 hours.
Tips to Make Web-tastic Spooky Bites
- Use fully cooled hard-boiled eggs so they are easier to peel.
- Choose a ripe avocado for the smoothest filling.
- Add the blue food coloring a little at a time.
- Use a small spoon or piping bag to fill the egg whites neatly.
- Cut one olive in half for the spider body. Cut another olive into thin strips for the legs.
- Taste the filling before adding it to the egg whites, then adjust the salt and pepper if needed.
Variation
You can use green food coloring instead of blue for a monster-style snack. Purple food coloring also works well for a Halloween party.
For a stronger flavor, add a small amount of garlic powder, paprika, or hot sauce to the filling. You can also replace Dijon mustard with yellow mustard if that is what you have.
FAQs
Can I make Web-tastic Spooky Bites ahead of time?
Yes. You can make them up to one day ahead. Cover them tightly and keep them in the refrigerator until serving time.

The mayonnaise and mustard help, but you can also add a small squeeze of lemon juice to the filling. Keep the eggs covered and chilled.
Can I use store-bought hard-boiled eggs?
Yes. Store-bought hard-boiled eggs can save time and work well in this recipe.
Can I make these without food coloring?
