Belgian urban submarine sandwich — half a baguette stuffed with a Belgian frikandel (deep-fried minced-meat sausage) or steak haché, topped with twice-fried Belgian frites, drowned in your choice of 22+ sauces (andalouse, samurai, dynamite, mammouth — each frituur has its lineup). Eaten standing at a friterie at 2am after Brussels nightlife. The carb-and-fat bomb that defines Belgian street food culture.
Mitraillette ('machine gun') is named because the long baguette resembles a gun barrel and the fries packed inside it the bullets. It originated in the Charleroi area of Wallonia, with roots in the interwar period — when money and provisions were scarce, people made do with bread and a few fries, the dish's humblest ancestor. Its modern form came much later: the French baguette was only produced in Belgium around 1975–76, and paired with Belgium's beloved frites the sandwich took its current shape (Charleroi's Robert la Frite, opened 1952, is one early landmark). It is popular across Wallonia and Flanders and into northern France, where its resemblance to an American burger earns it the name 'américain'; regional aliases include 'routier' (Liège) and 'spécial' (the Centre region). Brussels friteries — Maison Antoine on Place Jourdan, running since 1948, being the most famous — are celebrated for it, and Brussels students treat the mitraillette as the post-bar 'reset' meal: cheap, fast, and dense enough to absorb a lot of alcohol. The 22+ Belgian frites sauces (andalouse, samurai, cocktail, dynamite, mammouth, américaine, etc.) are an institution of their own, each friterie with its own signature combinations.
A mitraillette is the most Belgian thing you can eat. The first bite: crusty baguette gives way to crispy-outside-soft-inside frikandel (or steak haché), then crispy frites, then a tsunami of mayonnaise-based sauce that ties everything together with creamy-tangy-spicy depth. The textural variety per bite is unreal — bread crust + soft bread + crispy frites + meaty interior + sauce. Belgian frites done right (twice-fried, salted hot) are themselves the centerpiece. After 6 bites you understand: this is what 2am Brussels eats. The hangover prevention meal. The post-stadium-game ritual. Authentic Belgian street culture.
Two-stage frying is the technical key to Belgian frites: first fry at 150°C cooks the potato through without browning (the starch gelatinizes inside); 10-min rest lets surface moisture evaporate; second fry at 180°C creates the crispy exterior via Maillard reaction. This produces frites that are fluffy-inside AND crispy-outside — the canonical 'pommes frites' texture. The frikandel is a Belgian/Dutch deep-fried minced-meat sausage (similar to a frankfurter but without casing) that crisps to a golden bark in oil. The sauce delivery in massive quantity is essential — Belgian frites sauces are mayo-based, often with vinegar, mustard, or curry powder for character.
Variations
Frikandel is the canonical filling (the Walloon standard); swap in a beef patty (steak haché), Liège-style meatballs (boulettes), sausage (cervelas), or a fried schnitzel for variations; a veggie mitraillette uses falafel or a vegetarian frikandel; friterie-specific signatures vary by sauce combination; northern-French versions ('américain') use their own fried meats. Ultimately the mitraillette's character is set by how the meat, frites, and sauce are matched.
On the Palate
Where Mitraillette sits in the Belgian flavor cloud
Fry the frites twice — a gentle 150 度 first fry cooks the potato through and fluffs the inside, a hot 180 度 second fry crisps the shell; one single fry can only give you soft or greasy, never both textures at once.
Ingredients
Serves 1How it's made
10 steps · 20 min active + 5 min waiting
- 12 min
Prep the frikandel: thaw 1 Belgian frikandel sausage (if frozen). Score the surface with a knife to allow steam release.
- 212 min
Prep frites: peel and cut 2 large russet potatoes (~400g) into 1cm × 1cm × 8cm sticks. Soak in cold water 10 min; drain; pat very dry.
- 35 min
First fry of frites: heat 5cm vegetable oil to 150°C. Fry potato sticks 5 min until cooked through but still pale. Remove; let drain on rack 10 min.
Watch outFirst fry until the sticks are cooked soft but still pale — no color yet; that browning is the second fry's job.
- 46 min
Cook frikandel: heat 5cm oil to 175°C in a separate pot (or use the same oil after the first fry, raised in temp). Fry frikandel 6 min until deep golden and crispy. Remove; drain.
- 53 min
Second fry of frites: raise oil to 180°C. Fry the par-cooked potatoes again 3 min until deep golden, crispy outside, fluffy inside. Drain on paper; salt immediately.
Watch outSecond fry in hotter oil until deep gold — listen for the sizzle to quiet and the shells to turn crisp.
- 62 min
Cut 1 baguette piece (~25cm) lengthwise (almost through but not all the way). Optionally toast the inside briefly in a toaster or on a griddle.
- 71 min
Slice the frikandel lengthwise (don't fully separate).
- 84 min
Build the mitraillette: place frikandel inside the baguette. Top with a generous amount of frites (50% more than seems reasonable — the bread should be straining to close). Drizzle generously with sauce of choice: andalouse (Belgian-mayonnaise + bell pepper + paprika); samurai (mayonnaise + harissa); cocktail (mayonnaise + ketchup + brandy); dynamite (spicy mayonnaise + curry).
Watch outPack in far more fries than looks sensible — the baguette should be straining to shut.
- 91 min
Optional toppings: chopped onion, sliced pickles, shredded lettuce.
- 101 min
Wrap the mitraillette in parchment or foil to hold together. Eat immediately, standing or sitting outside a friterie. Pair with a cold Belgian Pils or a Coke.
