Overview

Kaassoufflé

Dutch Cheese Soufflé, Kaassouffle

This kaassoufflé recipe makes the Dutch snack-bar classic at home: a thick Gouda cheese sauce, chilled firm, shaped into rectangles, coated in breadcrumbs and deep-fried until the crust is golden and the centre is melted and stretchy. It is the pocket of cheese you find in every Dutch snackbar, and it takes only a handful of ingredients to get right. One serving is about 175 g, two pieces.

The kaassoufflé is a Dutch snack-bar classic: a pocket of melted cheese in a crisp breadcrumb crust, sold in snackbars alongside kroketten and frikandellen. Snackbars are the Dutch takeaway shops where fried snacks are the main event, and the kaassoufflé became one of their most loved items — eaten on its own with mustard, or tucked into a soft white roll as a broodje kaassoufflé.

Pairs well with: A spoonful of mustard and a soft white roll, with a cold beer or a glass of milk.

Execution Methodology & Culinary Technique

Step-by-Step Cooking Guide

Active 1h 20m

Prep Stage: Make the Cheese Mixture & Chill

70 Mins • Cooking, Chilling & Shaping

Grate the Gouda. Melt the butter in a pan, stir in 40 g of the flour and cook for 1 minute, then whisk in the milk a little at a time until smooth. Stir in the grated cheese, mustard, salt, nutmeg and white pepper until melted and thick. Spread the mixture in a shallow dish, cover, and chill in the fridge for 60 minutes until firm enough to shape.

Maestro Tip: Do not skip the full hour of chilling — a warm, soft mixture cannot be shaped or breaded, and it will burst in the oil.

  1. 1

    Make the Thick Cheese Sauce

    10 Mins Medium heat, ~160°C (320°F)

    Melt the butter in a pan over medium heat, stir in 40 g of the flour and cook for 1 minute, stirring all the time. Whisk in the milk a little at a time until smooth, then simmer for 2 minutes until thick. Take the pan off the heat and stir in the grated Gouda, mustard, salt, nutmeg and white pepper until the cheese has melted into a thick, smooth sauce.

    Add the milk slowly — a little at a time keeps the sauce smooth, while a whole jug at once makes lumps that no amount of stirring will fix.

    Done when: A thick sauce that holds its shape on a spoon and falls in slow ribbons.

  2. 2

    Chill & Shape the Rectangles

    70 Mins Fridge, 4°C (40°F)

    Spread the sauce in a shallow dish, press cling film onto the surface, and chill in the fridge for 60 minutes until firm. Cut the firm mixture into 8 even rectangles, about 8 cm by 4 cm.

    Wet the knife between cuts — it slices the chilled cheese cleanly instead of dragging it.

    Done when: A firm block that cuts cleanly and holds its shape when lifted.

  3. 3

    Bread the Soufflés

    10 Mins No heat

    Set out three shallow bowls: the remaining 30 g of flour, the beaten egg, and the breadcrumbs. Roll each rectangle in flour, dip it in the egg, then coat it all over in breadcrumbs, pressing gently so the crumbs stick. Chill the coated pieces for 10 minutes while the oil heats.

    Press the crumbs on firmly and seal the edges — any bare spot is where the cheese will escape in the oil.

    Done when: Every piece fully coated, with no bare cheese showing at the edges.

  4. 4

    Deep-Fry Until Golden

    5 Mins Hot oil, 175°C (350°F)

    Heat about 750 ml of oil in a deep pan to 175°C (350°F). Fry the soufflés two at a time for about 3 minutes until deep golden and crisp, turning once. Lift out with a slotted spoon and drain on a rack.

    Fry two at a time — crowding the pan drops the oil temperature and the coating turns soggy instead of crisp.

    Done when: Deep golden crust all over, with the cheese melted inside.

  5. 5

    Drain & Serve Hot

    2 Mins No heat

    Let the soufflés rest on the rack for 1 minute, then serve at once with mustard on the side. Cut one open before eating — the melted cheese inside stays hotter than the crust for a while.

    Serve on a rack, not on paper — paper traps steam and softens the crust within a minute.

    Done when: A crisp crust that gives way to stretchy, melted cheese.

Finishing Touches & Plating

Serve at once, with a spoonful of mustard on the side — the soufflé waits for no one, and the cheese is at its best in the first few minutes out of the oil.

Nutrition values are estimated — calculated from USDA FoodData Central values for the listed ingredients.

Vitamins & minerals: Calcium and phosphorus (Gouda), vitamin B12 and vitamin A (cheese, butter, egg), vitamin D (egg). Nutrition is estimated.

Protein in a Small Snack

One serving carries about 26.6 g of protein from the Gouda, egg and milk, which is what makes this small snack surprisingly filling.

Calcium from Gouda

Gouda brings calcium to the plate, and the egg in the coating adds B vitamins — the snack is rich, but it is not empty calories.

No Added Sugar

Made at home, you choose the cheese and the oil, and there is no added sugar in the snack at all — just cheese, milk, flour and crumbs.

Food Pairings

What to Eat With

To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:

Drinks

Cold Lager

A cold beer is the classic snackbar drink with a kaassoufflé because the bitter fizz cuts through the rich melted cheese.

Vegetables

Green Salad

A simple green salad with a sharp dressing gives a fresh, acidic bite that balances the fried, salty snack.

Sides

Soft White Roll

Tucked into a soft white roll, a kaassoufflé becomes a broodje — the way many Dutch snackbars serve it for lunch.

Sauces

Mustard Dip

A spoonful of mustard on the side adds a sharp, tangy note that wakes up the mild Gouda inside.

Complete menu

Serve kaassoufflés with a green salad and a soft white roll, then finish with fresh fruit.

Digestive Guardrails

What NOT to Combine

To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:

Biting Into a Freshly Fried Soufflé

Biting straight into a freshly fried kaassoufflé can burn the mouth, because the melted cheese inside stays far hotter than the crust. Cut it open and wait a minute. This is general food information, not medical advice.

Extra Salty Sauces and Crisps Beside It

The Gouda, breadcrumbs and mustard already make this snack salty, so adding extra salty sauces or crisps to the same plate pushes one snack too far on sodium. This is general food information, not medical advice.

General information only, not medical advice — consult a doctor for personal dietary decisions.

Who Should Eat It

Who Should Eat

  • General adultsA rich, salty snack — two pieces per serving, best eaten hot while the cheese still pulls.
  • ChildrenChildren love the crisp crust and melted cheese; cut a piece open first so the hot centre can cool for a moment.
  • ElderlySoft inside and easy to chew once cooled a little, but rich and salty — one piece at a time is the comfortable choice.
  • Pregnant womenFine as an occasional snack when the cheese sauce is cooked through and the soufflé is fried until piping hot; keep portions modest. Ask your clinician about portions.
  • Breastfeeding womenAn energy-rich snack; one serving is filling, so there is no need for a second helping.
  • AthletesA salty, energy-dense snack after training, with about 26.6 g protein per serving — pair it with a salad rather than more fried food.
  • Weight gainEnergy-dense at about 620 kcal for two pieces, so it suits weight gain as an afternoon snack.
  • Weight lossRich for a snack at about 620 kcal; one piece with a green salad is the lighter way to enjoy it.

Health Conditions — Adjust or Avoid

Conditions

  • DiabetesThe breadcrumb crust is the main carbohydrate, so keep to one or two pieces and eat a salad first to slow the rise. Ask your clinician about portions.
  • High blood pressureOne serving carries about 1,009 mg sodium, so do not add extra salty dips or crisps to the same snack. Ask your clinician about portions.
  • Kidney diseasePortions should stay modest, and the salt and protein content matter for some kidney diets. Ask your clinician about portions.
  • GoutCheese and egg are the main purine sources here, so keep to one modest serving and drink water with the snack. Ask your clinician about portions.
  • Stomach issuesDeep-fried food can feel heavy on a sensitive stomach; eat it slowly and keep the mustard mild. Ask your clinician about portions.
  • Cardiovascular diseaseThe cheese and frying oil add saturated fat, so one modest serving with a green salad is a better balance than a second helping. Ask your clinician about portions.
  • Fatty liverThe snack is energy-dense and fried, so keep portions modest and avoid eating it late at night. Ask your clinician about portions.
  • Food allergiesContains milk (Gouda, butter), egg, wheat (flour and breadcrumbs) and mustard. People with milk, egg, wheat or mustard allergy should not eat it unless a safe substitute is used. Ask your clinician about safe alternatives.
  • Special therapeutic dietsNot suitable for a low-fat or low-sodium therapeutic diet as written; any lighter version changes the dish and should be discussed with a clinician.

If you have a medical condition, consult your doctor before changing your diet.

Storage & Use

Storage & Use

How to store
Cool the fried soufflés quickly and store in a covered container; keep the unfried, breaded pieces in a single layer so the coating does not stick.
In the fridge
Fried soufflés keep 1 day in the fridge at 4°C (40°F) or below; the breaded, unfried pieces keep 2 days.
In the freezer
Unfried, breaded soufflés freeze for up to 1 month; fry from frozen for 5 minutes instead of 3.
How to reheat
Reheat in a hot oven at 190°C (375°F) for 8 minutes until crisp and steaming hot, to 74°C (165°F); do not microwave, or the crust turns soft.
Freezing recommended
Yes — before frying.
Signs it has spoiled
Sour smell from the cheese, a soggy or slimy coating, or mould.
