They’re a cheerful choice for Christmas dinner, holiday potlucks, or an appetizer platter. You can boil the eggs and prepare the filling ahead, then pipe and decorate the “trees” shortly before serving.

How to Make Christmas Tree Deviled Eggs
Step 1: Boil the Eggs
Place the eggs in a saucepan in a single layer and cover them with cold water by about 1 inch. Bring the water to a boil over medium-high heat.
Once it reaches a steady boil, cover the pan, turn off the heat, and let the eggs stand for 10–12 minutes. This helps cook the yolks through while reducing the chance of overcooking them.
Step 2: Cool and Peel the Eggs
Transfer the eggs to a bowl of ice water and leave them there for about 10 minutes. Cooling them quickly helps stop the cooking and can make peeling easier.
Gently tap each egg on the counter and roll it lightly to loosen the shell. Peel under cool running water if needed, then pat the eggs dry.
Step 3: Halve the Eggs and Remove the Yolks
Slice each egg in half lengthwise with a sharp knife. Carefully remove the yolks and place them in a medium bowl. Arrange the egg whites cut-side up on a serving platter or a tray.
If the egg whites wobble, trim a very small piece from the rounded underside so each half sits flat. Keep the cuts shallow so the filling still stays inside.
Step 4: Mash the Yolks
Mash the yolks with a fork until they are fine and crumbly. For a smoother filling, press them through a fine-mesh sieve or use a small food processor.
A smooth yolk mixture will pipe more neatly into tree shapes and help the filling hold its ridges.
Step 5: Mix the Pesto Filling
Add the mayonnaise, basil pesto, grated Parmesan, crushed red pepper flakes, salt, and black pepper to the mashed yolks. Stir until smooth and evenly green.
Taste the filling and adjust the seasoning. Add a little more pesto for stronger basil flavor, or a small spoonful of mayonnaise if you prefer a softer, milder filling. Keep the mixture firm enough to hold its shape when piped.
Step 6: Fill the Piping Bag
Spoon the filling into a piping bag fitted with a large star tip. If you don’t have a piping bag, use a zip-top bag and snip off one corner.
For cleaner piping, don’t overfill the bag. Work the filling toward the tip and twist the top closed so it doesn’t squeeze out behind your hand.
Step 7: Pipe the Christmas Trees
Pipe the filling onto each egg-white half in a tall, stacked swirl. Start near the center of the egg white, then move the tip in small circles while gradually lifting it to create a tree-like peak.
If one tree looks uneven, smooth it gently with a small spoon and pipe again. Keep the trees similar in size so they’re easy to serve together.
Step 8: Add the Decorations
Cut the red bell pepper into thin pieces, then use a small knife to cut tiny star shapes. If you don’t have a small star cutter, cut narrow strips or small triangles instead.
Place a pepper star on top of each piped tree. Sprinkle the trees lightly with additional Parmesan and a few crushed red pepper flakes. Add a small amount of finely diced red pepper around the platter for extra color, if desired.
Step 9: Chill and Serve
Cover the deviled eggs loosely and refrigerate for 20–30 minutes before serving. Chilling helps the filling firm up and gives the flavors time to blend.
Keep them refrigerated until just before serving, and bring out only the amount you plan to serve at one time.
Tips for the Best Christmas Tree Deviled Eggs
- Cool the eggs in ice water. This stops the cooking and makes the eggs easier to handle.
- Peel carefully. Smooth egg whites make a neater base for piping.
- Mash the yolks thoroughly. Small lumps can clog a piping tip.
- Keep the filling thick enough to pipe. Add extra mayonnaise a little at a time rather than all at once.
- Use a large piping tip. A wide star tip makes the tree ridges more visible and is less likely to clog.
- Chill the filling briefly if it’s soft. Refrigerate it for about 10–15 minutes before piping.
- Make the pepper stars small. A light decoration keeps each tree’s green shape visible.
- Use a steady hand. Pipe with even pressure, lifting gradually to make the tree taller toward the top.
- Keep the eggs cold. Refrigerate the platter until serving time and avoid leaving it out for a long stretch.
Easy Variations
Use Spinach for a Brighter Green
For a more vivid green color, blend a small handful of well-drained spinach into the filling. Add it gradually so the mixture remains thick enough to pipe.
Adjust the Pesto Flavor
Use 1 tablespoon of pesto for a milder taste or add another small spoonful for a stronger basil flavor. Pesto brands vary in saltiness, so taste the filling before adding more salt.
Make Them Mild
Leave out the crushed red pepper flakes and use only a little black pepper. The pesto and Parmesan will still give the filling plenty of savory flavor.
Add a Garlic Note
Stir a small pinch of garlic powder into the yolk mixture. Start with a little, since pesto often already contains garlic.
Try Different Toppers
Use tiny pieces of roasted red pepper, diced pimento, or a small red tomato piece instead of bell pepper stars. A sprinkle of finely chopped parsley or chives can add extra color.
Make a Rustic Version
If you don’t want to pipe the filling, spoon it into the egg whites and shape it into small mounds. Sprinkle with Parmesan, red pepper flakes, and diced red pepper for a simple finish.
Make-Ahead and Storage
You can boil, cool, and peel the eggs up to 2 days ahead. Store the peeled eggs in an airtight container in the refrigerator. You can also prepare the filling a day ahead and keep it covered in a separate container or piping bag.
For the neatest presentation, pipe and decorate the eggs on the day you plan to serve them. Store finished deviled eggs in a covered container in the refrigerator for up to 2 days.
Keep deviled eggs chilled until serving. For a party, place the serving platter over a larger tray filled with ice if it will be out for an extended period. Discard eggs that have been at room temperature for more than 2 hours, or sooner in a warm setting.
Frequently Asked Questions
How do I keep the green filling from becoming too soft?
Add the mayonnaise gradually and use a thick pesto. If the filling feels loose, refrigerate it for 10–15 minutes before piping. You can also mix in a little extra grated Parmesan to make it firmer.
Can I make the filling without a piping bag?
Yes. Spoon the filling into a zip-top bag and snip off a corner. For a simpler presentation, use a spoon to mound the filling in each egg white.
What can I use instead of red pepper stars?
Use a small piece of diced red bell pepper, pimento, or roasted red pepper on top of each tree. Small tomato pieces can also add a festive red accent.
Why is the filling not smooth?
The yolks may not have been mashed finely enough. Mash them thoroughly with a fork or press them through a sieve before mixing in the other ingredients.
Can I make these a day ahead?
Yes. Boil and peel the eggs and prepare the filling a day ahead. Store the two parts separately in the refrigerator, then pipe and decorate the eggs shortly before serving for the freshest appearance.
How should I transport them?
Arrange the finished eggs in a deviled egg carrier or a shallow container with a tight-fitting lid. Keep them chilled during transport and avoid stacking them.
Can I leave out the Parmesan?
Yes. The filling will still work without it, although it will have a milder, less savory flavor. You can replace it with a small amount of finely shredded cheddar or leave it out entirely.
Final Thoughts
These Christmas Tree Deviled Eggs bring festive color and a fresh basil flavor to a classic appetizer.
