Patatje Oorlog

War Fries, Patat Oorlog, Dutch War Chips

This patatje oorlog recipe double-fries thick-cut chips until golden, then piles them with a vegetarian satay sauce, mayonnaise and diced raw onion. One serving is about 395 g.

Patatje oorlog — literally 'war fries' — is the most famous order at a Dutch chip shop: thick fries with mayonnaise, peanut satay sauce and raw onion piled on top. The name is part of the dish's charm, and its exact origin is not settled — some say it comes from the messy, mixed-up look of the sauces, others from the clash of flavours on the plate. What is certain is that the combination has been a chip-shop staple in the Netherlands for decades, and that the satay sauce arrived with the Indonesian food traditions that became part of Dutch eating. This version keeps the satay sauce vegetarian, with no shrimp paste.

Pairs well with: Serve in a paper cone or tray with a fork, with the sauces spooned over the top so every chip gets some.

Prep Stage: Cut the Chips and Dice the Onion

15 Mins • Prep Work

Peel the potatoes and cut them into thick chips about 1.5 cm wide. Rinse them in cold water, dry them thoroughly, and dice the onion finely. Measure out the peanut butter, coconut milk, soy sauce, sugar, lime juice, chilli and garlic for the satay sauce.

Maestro Tip: Dry chips are the whole secret — wet chips spit in the oil and never crisp properly.

  1. 1

    First Fry

    10 Mins Oil at 160°C (320°F)

    Heat the oil to 160°C (320°F). Fry the chips in batches for 6 minutes until pale and soft all the way through but not coloured. Lift them out, drain and leave them to cool for 5 minutes.

    Fry in batches — a crowded fryer drops the oil temperature and the chips go soggy.

    Done when: Chips are soft and pale, with no colour yet.

  2. 2

    Make the Vegetarian Satay Sauce

    8 Mins Medium heat, about 175°C (350°F)

    Warm the peanut butter, coconut milk, soy sauce, brown sugar, lime juice, chilli and garlic in a small pan, stirring until smooth. Simmer gently for 3 minutes until it thickens enough to coat a spoon, then keep warm. This sauce is vegetarian — it is made with no shrimp paste, which some satay sauces contain.

    If the sauce gets too thick, thin it with a spoon of hot water, not more coconut milk.

    Done when: A smooth, glossy sauce that falls slowly off a spoon.

  3. 3

    Second Fry

    7 Mins Oil at 180°C (350°F)

    Raise the oil to 180°C (350°F). Fry the chips again in batches for 3 to 4 minutes until deep gold and crisp. Drain well and toss with the salt while still hot.

    The second fry is short and hot — that is what makes the outside crisp and the inside fluffy.

    Done when: Chips are deep gold, crisp outside and fluffy inside.

  4. 4

    Build the Patatje Oorlog

    3 Mins Serve hot, about 70°C (160°F)

    Pile the hot chips into a paper cone or tray. Spoon the warm satay sauce generously over one side and the mayonnaise over the other, then scatter the diced raw onion over the top and serve at once with a fork.

    Sauce the chips at the last second — five minutes of waiting and the crisp is gone.

    Done when: Hot chips, glossy sauces and a snowy layer of raw onion on top.

Finishing Touches & Plating

Eat it straight away, straight from the paper, with a little wooden fork — that is how a Dutch chip shop serves it, and the chips are at their best in the first five minutes.

Energy for a Hungry Afternoon

About 1,013 kcal per serving from potatoes, peanut sauce and mayonnaise — a proper snack, not a light one.

Potassium and Vitamin C

Potatoes are a good source of potassium and vitamin C, and the raw onion adds a fresh bite.

Vegetarian by Design

The satay sauce here is made with no shrimp paste, so the whole dish is vegetarian — check the label if you use a ready-made sauce.

Food Pairings

What to Eat With

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

Sides

Frikandel

A frikandel next to the fries is the classic Dutch snack-bar combination — the spiced sausage loves the same sauces.

Vegetables

Pickled Cucumber

Sharp pickled cucumber cuts through the rich peanut sauce and mayonnaise and resets the palate.

Drinks

Cold Beer or Cola

An ice-cold lager or a cola is the usual chip-shop drink — cold and fizzy against hot, salty chips.

Full Menus

Kroket

A beef kroket with mustard on the side turns the snack into a fuller Dutch fast-food meal.

Digestive Guardrails

What NOT to Combine

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

Reusing Frying Oil Too Many Times

Oil that has been heated again and again breaks down and can taste bitter. Use fresh oil and discard it when it darkens or smells off. This is general food information, not medical advice.

Eating Fries Left Standing

Chips lose their crisp in minutes and should be eaten hot. Do not leave fried chips at room temperature for hours. 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 chip-shop snack — one full portion is a meal in itself for most adults.
  • ChildrenChildren love it; use a mild satay sauce and less raw onion for younger ones.
  • ElderlySoft inside and easy to eat, but high in fat and salt — a small portion is enough.
  • Pregnant womenFine as an occasional snack; the sauces are salty, so keep the portion modest.
  • Breastfeeding womenA filling snack after a long day, though high in fat — enjoy it occasionally.
  • AthletesHigh in energy and carbohydrate, so it refuels well after training — but it is fried food, not a recovery staple.
  • Weight gainEasy to enrich: take a larger portion and add a frikandel on the side.
  • Weight lossAt about 1,013 kcal a serving this is a very rich snack — share one portion between two, or take half.

Health Conditions — Adjust or Avoid

Conditions

  • DiabetesAbout 75 g of carbohydrate per serving from the potatoes and the sweet satay sauce. Take a smaller portion and ask your clinician.
  • High blood pressureAbout 1,381 mg of sodium per serving. Use low-sodium soy sauce and less added salt; ask your clinician about your sodium target.
  • Kidney diseaseThis dish is high in sodium and fried fat, so it may not suit a restricted diet. Ask your clinician before making it a regular meal.
  • GoutPeanuts are the main purine concern here only in the sense that this is a rich snack; the bigger issue is fat and salt. Ask your clinician if flare-ups are frequent.
  • Stomach issuesFried food and raw onion can bother reflux or a sensitive stomach; eat a smaller portion and skip the raw onion. Ask your clinician if symptoms persist.
  • Cardiovascular diseaseVery high in fat, much of it from frying and mayonnaise. Share a portion and ask your clinician about your fat target.
  • Fatty liverA fried, high-fat snack can be heavy on the liver; keep it an occasional treat and load up on vegetables elsewhere. Ask your clinician for personal advice.
  • Food allergiesContains peanuts, egg (mayonnaise) and soy. Peanut allergy is serious — do not serve this to anyone with a peanut allergy, and ask your clinician if you have a food allergy.
  • Special therapeutic dietsNot suitable as written for a low-fat or low-sodium diet; bake the chips instead of frying and use a light sauce, and ask your clinician or dietitian.

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