Introduction

These Savory Mini Tuna Éclairs are an elegant twist on classic French choux pastry. Instead of a sweet cream filling, each light and airy éclair is filled with a creamy tuna mixture flavored with fresh lemon, Dijon mustard, herbs, and a touch of mayonnaise.

They’re delicate, flavorful, and surprisingly simple to prepare, making them perfect for brunch, holiday gatherings, afternoon tea, baby showers, or an elegant appetizer platter. The crisp, golden choux shells contrast beautifully with the cool and creamy tuna filling, while fresh herbs add brightness and color.

Best of all, you can prepare the components ahead of time and assemble the éclairs shortly before serving for an appetizer that looks impressive without requiring complicated preparation.

Ingredient Notes

Mini Éclair Shells
Light and airy choux pastry shells create the perfect base for this savory appetizer. You can use store-bought mini éclair shells for convenience or prepare homemade choux pastry for the best texture.

Tuna
Choose good-quality canned tuna packed in water or olive oil. Drain it very well before mixing so the filling stays creamy rather than watery.

Mayonnaise
Mayonnaise gives the tuna filling its smooth, rich texture. Full-fat mayonnaise provides the creamiest result, but a lighter version can also be used.

Dijon Mustard
A small amount of Dijon adds depth and a subtle tang without overpowering the tuna.

Fresh Lemon Juice
Freshly squeezed lemon juice brightens the filling and balances the richness of the mayonnaise.

Fresh Herbs
Parsley and chives add freshness, color, and a delicate herb flavor. Fresh dill is another delicious option.

Salt and Black Pepper
Season gradually after mixing the filling, especially since canned tuna can already contain salt.

Ingredients

For the Mini Éclair Shells

  • ½ cup (120 ml) water
  • 4 tablespoons (55 g) unsalted butter
  • ½ cup (65 g) all-purpose flour
  • 2 large eggs
  • ¼ teaspoon salt

For the Creamy Tuna Filling

  • 1 can (5 oz / 140 g) tuna, thoroughly drained
  • 3 tablespoons mayonnaise
  • 1 teaspoon Dijon mustard
  • 1 tablespoon fresh lemon juice
  • 1 tablespoon finely chopped fresh parsley
  • 1 tablespoon finely chopped fresh chives, plus more for garnish
  • ¼ teaspoon freshly ground black pepper
  • Salt, to taste
  • ½ teaspoon finely grated lemon zest, optional

The original version on Lea Recipes uses ready-made mini éclair shells with tuna, mayonnaise, Dijon, lemon, parsley and chives; this expanded version keeps that flavor profile while adding a homemade choux option and clearer measurements. 

Instructions

1. Prepare the Choux Pastry

Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.

Add the water, butter, and salt to a small saucepan. Heat over medium heat until the butter has completely melted and the mixture begins to simmer.

Add the flour all at once and stir vigorously with a wooden spoon. Continue cooking for about 1–2 minutes, stirring constantly, until the dough forms a smooth ball and begins to pull away from the sides of the pan.

2. Add the Eggs

Remove the saucepan from the heat and allow the dough to cool for about 5 minutes.

Add the eggs one at a time, mixing thoroughly after each addition. The finished dough should be smooth, glossy, and thick enough to hold its shape.

3. Shape the Mini Éclairs

Transfer the dough to a piping bag fitted with a large round tip.

Pipe approximately 12 small logs, about 2½–3 inches long, onto the prepared baking sheet. Leave some space between each éclair.

4. Bake

Bake for 10 minutes at 400°F (200°C).

Reduce the temperature to 350°F (175°C) and continue baking for approximately 15–18 minutes, or until the éclairs are puffed, crisp, and deeply golden.

Avoid opening the oven during the first part of baking, as this can cause the choux pastry to collapse.

Transfer to a wire rack and allow them to cool completely.

5. Make the Tuna Filling

In a medium bowl, combine the drained tuna, mayonnaise, Dijon mustard, lemon juice, parsley, chives, black pepper, and optional lemon zest.

Mix until creamy but still slightly textured. Taste and add salt if necessary.

6. Fill the Éclairs

Once completely cool, carefully slice each mini éclair lengthwise without cutting all the way through.

Spoon or pipe the creamy tuna mixture inside each shell.

7. Garnish and Serve

Sprinkle with additional chopped chives, freshly ground black pepper, or a little lemon zest.

Refrigerate the filled éclairs for about 15 minutes before serving, which is also the chilling step used in your current recipe. 

Serve chilled or slightly cool for the best texture.

Expert Tips for Perfect Mini Tuna Éclairs

Let the shells cool completely.
Never add the tuna filling while the choux pastry is still warm. The heat can soften the shells and make the filling watery.

Drain the tuna thoroughly.
Excess liquid is the biggest enemy of a creamy filling. Press the tuna gently with a fork after draining if necessary.

Keep some texture in the filling.
Avoid overmixing. A slightly chunky tuna filling gives these mini éclairs a much more appetizing texture.

Fill shortly before serving.
For the crispiest choux pastry, prepare the shells and tuna mixture separately, then assemble them shortly before serving.

Use a piping bag for an elegant finish.
A piping bag fitted with a large star tip makes the filling look especially attractive for parties or brunch tables.

Variations

Caper & Dill Tuna Éclairs

Add 1 tablespoon finely chopped capers and replace the parsley with fresh dill for a brighter, slightly tangy flavor.

Creamy Avocado Tuna Éclairs

Mix a few tablespoons of mashed ripe avocado into the tuna filling and slightly reduce the mayonnaise.

Spicy Tuna Éclairs

Add a little hot sauce, cayenne pepper, or finely chopped jalapeño for a spicy version.

Cucumber Tuna Éclairs

Add very finely diced cucumber for extra freshness and crunch. Remove as much moisture as possible from the cucumber first.

Smoked Salmon Version

Replace the tuna with finely chopped smoked salmon and add cream cheese, dill, and lemon zest for an elegant alternative.

Storage & Make-Ahead Instructions

Choux shells: Store unfilled éclairs in an airtight container at room temperature for up to 1 day. For longer storage, freeze them and briefly reheat them in the oven to restore their crisp texture.

Tuna filling: Prepare the filling up to 1 day ahead and keep it refrigerated in a tightly covered container.

Filled éclairs: These are best enjoyed the same day. Once filled, the choux pastry gradually absorbs moisture from the tuna mixture and becomes softer.

For the best result, keep the two components separate and assemble shortly before serving.

Frequently Asked Questions

Can I use store-bought mini éclair shells?

Yes. In fact, your original recipe specifically allows either 12 mini éclair shells or homemade choux pastry, so store-bought shells are a great shortcut when you want a quick appetizer. 

Can I prepare these ahead of time?

Yes. Prepare the shells and tuna filling separately the day before, refrigerate the filling, and assemble shortly before serving.

How do I keep the éclairs from becoming soggy?

Make sure the tuna is very well drained and the baked choux shells are completely cool and dry before filling them. Waiting until close to serving time to assemble them also helps.

Can I use tuna packed in olive oil?

Absolutely. Drain it thoroughly first. Tuna packed in olive oil can give the filling a slightly richer flavor.

What can I serve with mini tuna éclairs?

They pair beautifully with a fresh green salad, cucumber bites, smoked salmon appetizers, crudités, or other small savory bites.

Conclusion

Savory Mini Tuna Éclairs are an easy way to transform simple ingredients into an elegant appetizer. Crisp, airy choux pastry combined with creamy lemon-herb tuna creates a delicious contrast of textures and flavors.

Whether you serve them for brunch, a holiday gathering, afternoon tea, or a party platter, these bite-sized éclairs are easy to prepare ahead and beautiful enough for special occasions. Your current recipe already has a good tuna-Dijon-lemon base; this expanded version gives it the depth and useful information the existing short post is missing.
