Instructions

1. 1

   Cook the eggs

   Cook the six eggs for 9 minutes until hard-boiled. Rinse them under cold water, peel carefully and leave them to cool completely.

2. 2

   Make the roux

   Melt the butter in a saucepan over medium heat. Stir in the flour for 1 minute to form a roux.

3. 3

   Thicken the ragout

   Add the milk in small batches, stirring constantly, and continue stirring until the ragout is thick and smooth.

4. 4

   Season and chill

   Season the ragout with salt, pepper and nutmeg, then stir in the chopped chives. It should be very firm. Cool it for 10 minutes at room temperature, then refrigerate for at least 1 hour.

5. 5

   Set up coating

   Put flour, the beaten extra egg and breadcrumbs in three separate deep plates.

6. 6

   Wrap the eggs

   Take the ragout from the fridge. Spoon out about 60 g and flatten it in your palm. Set a peeled egg in the middle and fold the ragout around it until fully covered. Repeat with the remaining eggs.

7. 7

   Bread the balls

   Roll each ball in flour, then beaten egg, then breadcrumbs, pressing the crumbs firmly onto the surface. For an extra-crisp coating, repeat the beaten egg and breadcrumb layers once.

8. 8

   Chill the coating

   Refrigerate the breaded egg balls for 30 minutes so the coating can adhere.

9. 9

   Air-fry until golden

   Preheat the air fryer to 200°C. Spray the egg balls lightly all over with olive oil spray and arrange them in the basket. Cook for 12 to 14 minutes, turning them carefully halfway through, until golden brown and crisp.

10. 10

    Rest and serve

    Leave the egg balls to rest for 2 minutes, then serve straight away with mustard or mayonnaise on the side.

What is a Groningen egg ball?

The eierbal, or egg ball, is a regional Dutch snack associated with Groningen. It centres on a whole hard-boiled egg enclosed in savoury ragout and a crisp crumb coating.

This version keeps the classic combination of egg, creamy sauce and breadcrumbs, while using an air fryer to brown the outside. Chives add a fresh savoury note to the ragout.

Nutrition and macros by portion

The nutrition label shows one serving as written: 275 calories, 14g protein, 28g carbs, 12g fat.

The eggs supply most of the protein, while the milk and butter contribute fat and some additional protein. Flour and breadcrumbs provide much of the carbohydrate, with butter and the coating adding to the fat. To balance the plate, serve one egg ball with a generous portion of vegetables or salad.

Building a firm ragout

Roux first: cooking the flour in melted butter for a minute helps it blend into the sauce. Add the milk gradually and keep stirring to help prevent lumps.

Thickness matters: the ragout needs to be firm enough to mould around an egg. Keep stirring until smooth and thick, then give it the full chilling time to set.

Wrapping each egg

Flatten the ragout in your palm to make an even layer around the egg. Bring the edges together carefully and check that no part of the egg is exposed.

Keep your hands lightly damp if the ragout sticks, and work with one portion at a time. The recipe uses about 60 g of ragout for each egg.

Getting the coating to stick

Three stages: flour gives the beaten egg a surface to cling to, and the egg helps the breadcrumbs adhere. Press the crumbs gently but firmly all over.

For a thicker crust, repeat the egg and breadcrumb stages once. A 30-minute rest in the fridge helps the coating stay in place when the balls are turned.

Air-fryer texture and timing

Preheat the air fryer to 200°C before cooking. The balls need 12 to 14 minutes, with a careful turn halfway through, to brown on all sides.

Look for a golden, crisp exterior and handle the balls gently as you turn them. Rest them for 2 minutes before serving so the hot filling settles.

Serving the egg balls

Serve them immediately, as the coating is at its crispest straight from the air fryer. Mustard or mayonnaise makes a simple dip, as suggested in the recipe.

For a more complete plate, pair an egg ball with a green salad or cooked vegetables. Cut through the middle to show the egg and ragout layers.

Recipe notes & tips

• Cool the hard-boiled eggs completely before wrapping them.
• Add the milk in small batches and stir continuously for a smooth ragout.
• Chill the ragout until firm before trying to shape it around the eggs.
• Make sure the ragout completely covers each egg before breading.
• Turn the balls carefully halfway through cooking to avoid splitting the coating.
• Serve soon after the 2-minute rest for the crispest finish.

Variations

• Extra-crisp coating: Repeat the beaten egg and breadcrumb layers once as described in the method.
• Herb swap: Use another finely chopped soft herb in place of the chives for a different flavour.
• Peppery ragout: Add extra black pepper to the ragout seasoning to give it more bite.
• Mustard side: Serve with mustard for a sharp contrast to the creamy filling.
• Mayonnaise side: Offer mayonnaise alongside the egg balls for a mild, creamy dip.

Common mistakes to avoid

• Runny ragout: Keep stirring until it is very thick, then chill it for at least 1 hour before shaping.
• Warm eggs: Let the hard-boiled eggs cool completely so the ragout is easier to mould around them.
• Exposed egg: Fold the ragout over the whole egg and check for gaps before breading.
• Loose crumbs: Press the breadcrumbs onto the surface and chill the coated balls for 30 minutes.
• Rough turning: Turn the balls carefully halfway through cooking so the coating does not break.

How to store

Refrigerate leftovers promptly in a covered container and eat within 2 days. Reheat in the air fryer until hot throughout; the coating may be less crisp after storage.
