Finnish egg butter, or munavoi, is a traditional Finnish spread made with hard-boiled eggs and butter. It is best known as a topping for warm Karelian pies, but also works well with new potatoes, asparagus, and rye bread.
With only a few ingredients, munavoi creates a rich but fresh-tasting spread that has been part of Finnish home cooking for generations.
A Traditional Finnish Favorite
In Finland, munavoi is best known as the classic topping for Karelian pies. Warm rice pies topped with cool egg butter are one of the most iconic combinations in Finnish cuisine and are served everywhere from everyday coffee tables to festive gatherings.
Although the ingredients are simple, the contrast between creamy butter and finely chopped eggs creates a flavor and texture that feels both comforting and satisfying. Many families have their own version, adjusting the texture and salt level slightly to their taste. Some prefer it smoother and creamier, while others like it more rustic with visible pieces of egg.
Some versions also include cottage cheese, which makes the spread lighter and extra creamy. If you wish, you can replace one of the eggs with a similar amount of cottage cheese for a slightly softer texture and milder flavour.
Simple Ingredients, Best Quality
Because this recipe contains only a few ingredients, quality matters. Good butter and properly cooked eggs make a noticeable difference.
For the best texture, boil the eggs until just hard-boiled rather than fully overcooked. Slightly softer yolks keep the mixture creamier and fresher tasting.
I prefer using salted butter and finishing the mixture with a little flaky salt if needed. The result stays rich and flavorful without becoming overly heavy.
Keep the texture slightly rustic rather than completely smooth. Small pieces of egg give the spread more character and work especially well with warm breads, potatoes, and Karelian pies.
How to Use Munavoi
Finnish egg butter is most traditionally served spooned over warm Karelian pies. The cool, creamy butter melts slightly into the hot rye crust and rice filling, creating a classic Finnish combination that has been loved for generations.

It also works beautifully with boiled new potatoes. Spoon munavoi over warm potatoes and finish with fresh dill for a simple, comforting Nordic-style side dish where the butter melts gently over the potatoes.
One of my newer favourite ways to enjoy it is with white asparagus. The creamy egg butter pairs surprisingly well with the mild, delicate flavour of asparagus, creating a simple but elegant dish that feels both traditional and slightly modern.
Texture Matters
One small detail makes a big difference in munavoi: how the eggs are cooked and chopped.
The best result comes from eggs that are just hard-boiled, not overcooked. This keeps the yolks softer and helps the mixture stay creamy.
Finely chopping the eggs creates a balanced texture, but leaving a little rustic structure keeps the spread more interesting and traditional.
Serving Suggestions
Serve munavoi chilled or at cool room temperature depending on your preference.
It works especially well:
- on Karelian pies
- with archipelago bread
- with boiled new potatoes
- with white asparagus
- as part of Nordic brunch tables
- at coffee table gatherings and seasonal meals
Because it is so simple, it also fits beautifully into buffet-style serving.
