French Eggs Mimosa: A Classic Mustard-Filled Egg Recipe

French eggs mimosa, or œufs mimosa, are hard-boiled eggs filled with a smooth mixture of their yolks, mayonnaise, and Dijon mustard. Served chilled as a starter or appetizer, they are finished with a fine crumble of yolk that resembles mimosa blossoms; family versions vary in seasoning and garnish.

Ingredients

6 large eggs (about 300 g without shells)
3 tablespoons (45 g) mayonnaise, preferably commercially prepared
1 teaspoon (5 g) Dijon mustard
1 teaspoon (5 ml) lemon juice or white wine vinegar
⅛ teaspoon (about 0.75 g) fine salt, plus more to taste
⅛ teaspoon (about 0.25 g) ground white pepper, or a small pinch of black pepper
1 tablespoon (3 g) finely snipped chives, for garnish
¼ teaspoon (about 0.5 g) sweet paprika, optional
Water, enough to cover the eggs by about 1 inch (2.5 cm)

Instructions

Bring the water to a boil. Set the eggs in a single layer in a saucepan that fits them without crowding. Add cold water to cover by about 1 inch (2.5 cm). Set the pan over medium-high heat and bring the water to a full boil, which usually takes about 8 minutes, depending on the pan and burner. Starting the eggs in cold water helps them heat evenly and makes the timing easier to manage.
Cook the eggs until firm. Once the water boils, lower the heat enough to maintain a gentle boil and cook the eggs for 11 minutes. Check that the whites and yolks are firm; USDA FSIS guidance for whole boiled eggs is to cook until the yolk and white are firm rather than to use a thermometer. Avoid a hard, vigorous boil, which can knock the eggs together and crack the shells.
Cool promptly. Transfer the eggs with a slotted spoon to a bowl of ice water. Leave them for 10 minutes, adding more ice if the water warms substantially. Cooling stops the cooking and makes the eggs easier to handle. Drain and dry them before peeling.
Peel and halve. Tap each egg gently on the counter to crack the shell all over, then peel under a thin stream of cool water if needed. Slice the eggs lengthwise with a clean knife. Wipe the blade between cuts for neater edges. Lift the yolks into a small bowl, keeping the whites intact; arrange the empty halves cut-side up on a serving plate.
Make a smooth filling. Mash the yolks thoroughly with a fork, then mix in the mayonnaise, Dijon, lemon juice, salt, and white pepper. Work the mixture until it is creamy, with no large dry lumps. Taste and adjust the salt, pepper, or acidity a little at a time. The filling should taste gently tangy and savory, not sharply sour or so loose that it runs out of the whites.
Fill and finish. Spoon the yolk mixture into the egg-white cups, or transfer it to a piping bag or a small food-storage bag with one corner snipped off and pipe it in. Sprinkle the tops with chives and, if using, a light dusting of paprika. For the classic mimosa look, push a reserved spoonful of cooked yolk through a fine-mesh sieve over the filled eggs. Chill until serving.

Tips

Peel carefully. Eggs that are very fresh can be harder to peel cleanly. If you know your eggs are fresh from the farm, allow an extra minute for peeling and work gently under cool running water. Small tears in the white are harmless; cover them with filling or use them as the less-decorative pieces.
Adjust the filling gradually. Egg yolks vary slightly in size, and mayonnaise brands differ in thickness and tang. Start with the listed amount, then add mayonnaise by the teaspoon if the mixture feels dry. Add lemon juice or vinegar in small drops so the filling does not become runny.
Use a sieve for the garnish, not necessarily the filling. A fork is enough to mash the filling for a home-style result. Sieving a little yolk over the top makes the signature fine, fluffy finish; pushing the whole filling through a sieve takes more effort and is not essential.
Keep the eggs cool while you work. If assembling takes longer than expected, return the filled plate to the refrigerator rather than leaving it on the counter. For easy transport, keep the halves in a covered container with a cold pack and garnish shortly before serving.

Serving Suggestions

Serve the eggs chilled or just slightly cool, arranged on a small platter as an apéritif snack, picnic dish, or first course. They pair well with a green salad dressed with vinaigrette, sliced radishes, crusty bread, or a board of simple vegetables. For a light French-inspired lunch, offer two egg halves per person with lettuce, tomato, and a few slices of baguette. Their mild, creamy filling also makes them a useful contrast beside sharper pickles or mustardy salad dressing.

For a tidy party platter, use a flat dish or an egg plate so the halves do not slide. A bed of lettuce can help hold them in place, but keep the leaves dry so the whites do not sit in water. Add the chives, paprika, and sieved yolk shortly before serving for the clearest color and texture. If the eggs are part of a buffet, put out a smaller plate at a time and keep the rest refrigerated.

Variations

There are plenty of family and regional variations, so the seasoning can be adapted without changing the basic method. For a slightly richer filling, replace 1 tablespoon (15 g) of the mayonnaise with crème fraîche or thick sour cream; the result is less mayonnaise-forward and a little more tangy. A pinch of cayenne or a few drops of hot sauce adds warmth, while finely chopped cornichons give the filling a crisp, tart bite. Keep additions finely chopped so they do not block a piping tip.

For a milder flavor, use ½ teaspoon (2.5 g) Dijon instead of a full teaspoon, or substitute smooth yellow mustard. Yellow mustard is softer and often sweeter, so the finished filling will taste less sharp and less distinctly French. If you do not have white pepper, black pepper works well, though its dark flecks will show. Parsley can stand in for chives, and a small pinch of smoked paprika gives a more pronounced smoky note than sweet paprika.

To make the platter more decorative, pipe the filling with a star tip and place a tiny chive piece or a small parsley leaf on each egg. Keep garnishes restrained so the yolk and mustard remain the main flavors. You can also leave the halves unpiped and use a teaspoon; the classic character comes from the seasoned yolk filling and the fine yolk topping, not from elaborate presentation.

Storage and Reheating

Eggs mimosa are served cold and should not be reheated. Refrigerate them within 2 hours of preparation or serving, sooner if the room is very warm. Store the finished eggs in a covered, shallow container in the refrigerator at 40°F (4°C) or colder, and use them within 3 to 4 days. For the best appearance, however, serve them the day they are made; the whites can dry slightly and the garnish can lose its delicate texture over time.

You can prepare the hard-boiled eggs up to 2 days ahead, refrigerate them unpeeled in a covered container, and make the filling and assemble the platter on serving day. Alternatively, prepare the filling and whites separately, cover both, and refrigerate them; fill the whites within a day for the freshest texture. Do not leave the eggs at room temperature while waiting to serve, and discard any that have been out for more than 2 hours rather than returning them to the refrigerator.

Frequently Asked Questions

Why are they called eggs mimosa?
The finely grated or sieved yolk sprinkled over the filled eggs resembles the small yellow flowers of the mimosa plant. The name describes the traditional finish; it does not mean the eggs contain mimosa flowers.

Can I make eggs mimosa the day before?
Yes. For the neatest result, boil and peel the eggs, then store the whites and yolk filling separately in covered containers in the refrigerator. Assemble and garnish the platter on the day you plan to serve it. Fully assembled eggs can also be refrigerated overnight, though the garnish may look less fluffy.

How do I keep the yolk filling from being lumpy?
Mash the yolks finely before adding the wet ingredients, then stir until the mixture is uniform. If you want an especially smooth texture, press the yolks through a fine-mesh sieve before mixing. Add mayonnaise gradually; too little leaves dry crumbs, while too much can make the filling loose.

What if I do not have a piping bag?
A teaspoon works perfectly well. For a similar piped look, spoon the filling into a clean food-storage bag, press it toward one bottom corner, and snip off a very small piece of the corner. Cut a little more only if needed, since a wide opening makes it harder to control the amount.

Why do hard-boiled egg yolks sometimes have a green ring?
A gray-green ring can form when eggs are cooked too long or cooled too slowly. It is generally a quality issue rather than a sign that the egg has spoiled, but it can affect the appearance and texture. Follow the cooking time, cool the eggs promptly in ice water, and avoid leaving them in hot water after cooking.

Can I use regular yellow mustard instead of Dijon?
Yes. Use the same amount to start, then taste the filling before adding more. Yellow mustard tends to be milder and sweeter, so the eggs will have a softer flavor and less of Dijon’s tang. A little extra lemon juice can restore brightness if the finished mixture tastes flat.
