Instructions

1. 1

   Halve the rolls

   Slice each rye roll horizontally. For a crisper result, briefly toast the halves in a toaster or under the grill.

   Spread the mustard

   Generously spread the cut sides with wholegrain mustard, using a little more or less to taste.

3. 3

   Place one or two slices of mature Gouda on each roll; it is fine if the cheese extends beyond the edges.

4. 4

   Top with vegetables

   Slice the gherkins diagonally and scatter them over the cheese, then add a few rings of red onion.

What is Halve Hahn?

Halve Hahn is a well-known snack from Cologne, traditionally built around a rye roll and cheese. Despite the name, it contains no chicken.

This version pairs mature Gouda with coarse mustard, tangy gherkins and sharp red onion. The mix of savoury, piquant and crisp toppings makes a plain roll feel like a complete little meal.

Nutrition and macros by portion

The nutrition label shows one serving as written: 350 calories, 19g protein, 39g carbs, 13g fat.

The rye rolls supply most of the carbohydrates, while Gouda contributes much of the protein and fat. Mustard and gherkins add flavour and some sodium, so serve a roll with salad or raw vegetables for a more balanced plate.

Choose a sturdy roll

Rye rolls: Their robust flavour stands up to the strong cheese and mustard, while a firm crust helps the toppings stay in place.

Toasting: A brief toast is optional, but adds crunch and helps the cut surface hold the mustard without becoming too soft.

Balance the toppings

Mature Gouda: Its concentrated savoury flavour is the main event, so use slices that cover the roll without piling them too high.

Mustard: Coarse wholegrain mustard gives both tang and texture. Spread it generously, adjusting the amount to suit your taste.

Get the texture right

Gherkins: Cut them diagonally into slices so they are easy to arrange and give each bite a crisp, sharp contrast to the cheese.

Red onion: Thin rings bring a fresh, punchy bite. Keep them fine so they complement rather than overpower the other toppings.

Season without overdoing it

Black pepper: Grind it over the assembled rolls for a little warmth. The cheese and mustard are already savoury, so taste before adding any salt.

Serve it simply

Serving board: Bring the rolls to the table soon after assembling so the bread keeps its texture. Put extra gherkins and mustard alongside for anyone who wants more.

On the side: A crisp green salad or sliced raw vegetables make a fresh contrast; the rolls also work well as part of a casual sharing spread.

Recipe notes & tips

• Use cheese sliced thinly enough to sit neatly on the roll.
• Pat very wet gherkins dry before adding them if you want to keep the bread crisp.
• Toast the rolls only briefly so they remain easy to bite.
• Spread mustard right to the edges for flavour in every bite.
• Keep extra mustard and gherkins on the side rather than overloading the rolls.

Variations

• Add radishes: Slice them thinly for extra crunch and a peppery note.
• Use another cheese: Try a similarly mature, firm cheese in place of Gouda.
• Try caraway rye: Choose rye rolls with caraway for a more aromatic base.
• Add fresh herbs: Scatter a little chopped chive over the onion for a fresh finish.
• Make it milder: Use less red onion and a gentler mustard.

Common mistakes to avoid

• Too much mustard: An excessive layer can overwhelm the cheese; start with a generous but even spread.
• Thick onion rings: They can dominate each mouthful; slice the onion thinly.
• Wet gherkins: Excess pickle liquid can soften the bread; drain or pat the slices dry.
• Over-toasting: Very crisp rolls can be awkward to bite; toast only briefly if using the toaster or grill.
• Adding salt automatically: Gouda and mustard are already savoury; taste first and season with pepper.

How to store

These rolls are best assembled and eaten straight away, as the mustard and gherkins can soften the bread. Store any leftover components separately in the fridge, covered, and assemble fresh; avoid reheating the cheese-topped rolls.
