Traditional Polish Deviled Eggs (Jajka Faszerowane)
Traditional Polish deviled eggs feature hard-boiled eggs filled with a mixture of creamy yolks, sauteed mushrooms, fresh parsley and a bit of mayo. It’s a simple but delicious and timeless appetizer, perfect for Easter and beyond.
Boil eggs: Place the eggs in a pot, add cold water and 1.5 teaspoons of salt, cover and bring to the boil then lower the heat and simmer gently for about 9 minutes. Remove from the heat, drain and place the eggs in ice water. After about 2 minutes tap each egg gently against a counter to break the shell (in one place) and return to the pot for another minute. Drain and set aside.TIP: As the eggs cool top up with more cold water, if necessary.
Prepare mushrooms: In a large pan melt the butter with oil, add the onion and cook gently for 3 minutes stirring often (don’t let it brown). Add the mushrooms, salt and pepper, stir and cook on a medium heat for about 12 minutes until all the moisture has been absorbed and the mushrooms start to brown a little, stirring occasionally. Remove from the heat and set aside to cool.TIP: While you are waiting for the mushroom mixture to cool prepare the egg yolks.
Prepare eggs: Once cooled completely gently tap the eggs against a counter/cutting board to break the shell all over then peel. Cut each egg in half lengthwise and remove the yolks.
Prepare yolks: Place the yolks of 6 eggs in a large shallow bowl and mash with a fork until crumbly (not completely smooth or creamy). For a coarser texture chop the yolks into small pieces using a knife.TIP: Use the 2 remaining yolks in an egg salad or another recipe with hard-boiled eggs.
Add mushrooms: Add the mushroom mixture (once cooled completely) and parsley then stir, add the mayonnaise and mustard and stir again. Taste and adjust the seasoning if necessary.
Stuff eggs: Scoop the stuffing mixture, shape it using 2 large spoons then fill each egg half.
Serve: Arrange the eggs on a plate/platter, drizzle over a little mayo (this is optional), scatter fresh chives, cress or similar. Serve.TIP: I like to add a drop of mayo or sour cream under each egg to help them stay in one place. You can use tender salad leaves, instead.
Notes
Make sure your eggs are at room temperature (to prevent cracking as they boil).
I recommend boiling the eggs with about 1.5 teaspoons of salt (to prevent the whites escaping if any of the eggs crack).
Wipe the mushrooms with a paper towel to remove any soil or grit. Do not rinse.
To save time boil the eggs and prepare the mushrooms simultaneously.
Fill the egg halves with generous amounts of the stuffing mixture.
Polish mushroom deviled eggs are best served at room temperature. Keep refrigerated, covered, for up to 2 days.
