Overview

Mitraillette

Belgian Fries Sandwich

This mitraillette recipe stuffs a crusty baguette with a fried pork patty, a pile of golden fries, salad and a creamy Andalouse-style sauce. It is the sandwich Belgium’s friteries are famous for — messy, generous and best eaten with both hands. One serving is about 505 g.

The mitraillette — “submachine gun” in French, named for the way it is eaten fast, or for the baguette’s shape — is the sandwich of Belgium’s friteries, the fry shops that are a national institution. A demi-baguette is filled with fried meat, a heap of twice-fried chips and sauce, and eaten standing up or on the go. Every friterie has its own sauce — Andalouse, Samouraï, Brésil — and every Belgian has a favourite. It is fast food, but it is also a point of pride: the chips must be fried twice, in beef dripping if you ask a purist.

Pairs well with: An ice-cold lager or a glass of sparkling water

A good mitraillette has a crackling baguette, crisp twice-fried chips, juicy meat and sauce in every bite — never soggy, never skimpy.

Execution Methodology & Culinary Technique

Step-by-Step Cooking Guide

Active 45m
P

Prep Stage: Cut the Fries and Mix the Sauce

20 Mins • Cutting & Mixing

Peel the potatoes (400 g), cut them into 1 cm batons, rinse in cold water and dry very well. Stir the mayonnaise (60 g) with the tomato paste (15 g) and a pinch of paprika for the Andalouse-style sauce. Slice the tomato (60 g) and onion (40 g), shred the lettuce (30 g), and split the baguettes (300 g) lengthways.

Maestro Tip: Dry potatoes fry crisp; wet potatoes steam and go limp.

  1. 1

    Fry the Chips Twice

    20 Mins Oil at 180°C (355°F)

    Heat the oil to 180°C (355°F). Fry the potato batons (400 g) for 5 minutes until pale and soft, lift out and rest for 5 minutes, then fry again for 3 minutes until deep golden and crisp. Drain well and salt at once with half the salt (1 g).

    The first fry cooks the inside; the second fry makes the crust. Skip the rest and they go limp.

    Done when: Deep golden outside, fluffy inside.

  2. 2

    Fry the Pork Patties

    10 Mins Medium-high heat, about 190°C (375°F)

    Fry the pork patties (160 g) in a little oil over medium-high heat for 4–5 minutes a side until browned and cooked through to 71°C (160°F) in the centre. Season with the remaining salt (1 g).

    Press the patties flat before frying so they fit the baguette and cook evenly.

    Done when: Browned outside, no pink in the middle; juices run clear.

  3. 3

    Warm the Baguettes

    5 Mins Oven at 180°C (350°F)

    Warm the split baguettes (300 g) in the oven at 180°C (350°F) for 5 minutes until the crust crackles.

    Warm bread holds the hot filling without going soggy.

    Done when: Crust crisp and crackling; inside warm and soft.

  4. 4

    Sauce the Bread

    2 Mins Room temperature, about 20°C (68°F)

    Spread the Andalouse-style sauce (mayonnaise 60 g mixed with tomato paste 15 g) generously inside each warm baguette.

    Sauce both sides — a dry half-baguette ruins the sandwich.

    Done when: Both halves coated edge to edge.

  5. 5

    Build the Mitraillette

    5 Mins Serve at once

    Lay a pork patty in each baguette, pile in the hot fries, add the lettuce (30 g), tomato (60 g) and onion (40 g), and spoon over the rest of the sauce. Press the top down gently and serve at once, wrapped in paper.

    Pile the fries high — a mitraillette should overflow a little.

    Done when: Sandwich full to bursting, fries hot and crisp.

Finishing Touches & Plating

Eat it at once, with both hands and plenty of napkins — a mitraillette waits for no one.

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

Vitamins & minerals: B vitamins and iron (pork), vitamin C (potato, tomato), vitamin A (lettuce, tomato).

A Properly Filling Lunch

About 29 g of protein per serving from the pork, with slow carbs from the bread and potatoes.

Fresh Salad Inside

Lettuce, tomato and onion add crunch, vitamin C and fibre to a rich sandwich.

Cooked Fresh, Not Processed

The patties and fries are cooked from raw potatoes and fresh pork at home, not reheated from a packet.

Food Pairings

What to Eat With

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

Drinks

An Ice-Cold Lager

A cold Belgian lager cuts the richness of the fried pork and the creamy sauce.

Vegetables

A Simple Green Salad

Crisp leaves with a sharp vinaigrette balance the fries and sauce.

Sides

Pickles

Sharp pickled onions or gherkins cut through the fat and refresh the palate.

Full Menus

With Extra Fries on the Side

Friteries serve it with more fries and mayonnaise — order a small portion, not a second full sandwich.

Complete menu

Serve the mitraillette with a small green salad, pickles and an ice-cold lager — and a pile of napkins.

Digestive Guardrails

What NOT to Combine

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

A Sweet Sauce

Ketchup-heavy or sweet chilli sauce would drown the savoury pork and fries; keep the sauce creamy and lightly spiced. This is general guidance, not medical advice.

Letting It Sit

The fries steam inside the bread and go soft within minutes, so build and eat the sandwich straight away.

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

Who Should Eat It

Who Should Eat

  • General adultsA big, hearty lunch — one sandwich is a full meal, best eaten fresh.
  • ChildrenSuitable from age 3+; cut into halves for small hands and go easy on the sauce.
  • ElderlyGood in a modest portion — cut in half and eat it warm; the fries go soft fast.
  • Pregnant womenGenerally suitable; the pork must be cooked right through to 71°C (160°F).
  • Breastfeeding womenGenerally suitable; a filling, energy-rich lunch — keep the portion modest.
  • AthletesA good energy-dense meal after training, with protein from the pork and carbs from the bread and fries.
  • Weight gainA good choice — take the full sandwich with extra fries on the side.
  • Weight lossA rich sandwich — take half, load up on the salad, and skip the extra fries.

Health Conditions — Adjust or Avoid

Conditions

  • DiabetesThe bread and fries are the main sources of carbs — take half a sandwich with salad and ask your clinician about portion size.
  • High blood pressureMost of the sodium comes from the bread, sausage and sauce; season lightly. Ask your clinician about a suitable portion.
  • Kidney diseaseLimit the portion (potassium from the potatoes); ask your clinician about portion size.
  • GoutEat occasionally and in smaller portions — pork sausage is a rich food.
  • Stomach issuesUsually fine; the fried food and rich sauce can trouble sensitive stomachs, so keep the portion modest.
  • Cardiovascular diseaseKeep the portion modest and favour the salad over the fries; the dish is rich in saturated fat and salt.
  • Fatty liverKeep to half a sandwich with salad instead of extra fries — the fried food and sauce add up fast.
  • Food allergiesContains wheat (gluten) and egg (mayonnaise), and pork. Naturally free of nuts and fish.
  • Special therapeutic dietsIf you follow a prescribed low-sodium diet, use low-sodium sausage and less sauce, and check with your clinician.

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