The best street sandwich in the world doesn’t come from the United States. It comes from Argentina, it’s called choripan, and it relies on two things: a grilled sausage with character and a handmade chimichurri. Nothing else.

Final result — Choripan just like in Buenos Aires: crispy toasted bread, smoky merguez, and homemade chimichurri that wakes up the whole sandwich.

Imagine the bread — a firm ciabatta, lightly toasted, that crackles under your fingers before giving way. Inside, a lamb merguez whose skin has blistered on the barbecue, with those little almost-black spots that smell of smoked cumin and embers. On top, a generous spoonful of bright green, shiny chimichurri, with small pieces of parsley and garlic melting on the heat of the sausage. It drips a little. That’s normal. In fact, that’s the point.

Why you’ll love this recipe

✓Chimichurri changes everything : Not the store-bought jar version — you make this one in 5 minutes with fresh parsley and garlic. The difference is immediate: a vibrant, slightly acidic herb kick that cuts through the fat of the sausage.

✓It’s a weekend recipe, not a weekday recipe : Not in the sense that it’s complicated. In the sense that you take your time. You prep the chimichurri in advance, you let the barbecue come up to temperature, you don’t rush anything. You have to earn it a little.

✓Two main ingredients, zero frills : Bread, sausage, sauce. That’s the choripan equation. No lettuce, no tomato, no pickles — nothing to interfere with the flavors. If you feel like adding something, you’ve got the wrong recipe.

✓Lamb merguez plays the part perfectly : Since Argentine chorizo is hard to find in Europe, lamb merguez is the best substitution: spicy, just fatty enough, with that cumin and coriander taste that pairs perfectly with the herbaceous chimichurri.

Ingredient Notes

Ingredients

A few simple ingredients — that’s all it takes to make the best sandwich of your life.

Lamb merguez : Look for artisanal merguez at a butcher — supermarket ones tend to be too thin and dry out quickly during cooking. A good merguez should be firm to the touch, with a natural casing that resists before snapping on the grill.
Ciabatta or baguettine bread : The bread must be firm. Not a soft brioche-style baguette — the bread is going to soak up the sausage juices and chimichurri, and if it’s too soft, it collapses at the second bite. A well-aerated ciabatta or a half-baguette does the job perfectly.
Flat-leaf parsley : Strictly flat-leaf parsley, never curly. Curly is more bitter, less fragrant, and chops poorly. For chimichurri, you want broad-leaf parsley that releases its essential oils under the knife — a peppery, herbaceous, almost anise-like smell.
Garlic : Three cloves for four people is the baseline. Some use five. Raw garlic in chimichurri remains powerful even after infusing — if you’re not a big fan, stick to three cloves and avoid chopping it too finely.
Red wine vinegar : This is the acidity of the chimichurri. One tablespoon is enough — the idea isn’t to make a vinaigrette, but to provide a touch of acidity that wakes up the herbs and counterbalances the sausage fat. Apple cider vinegar also works if that’s what you have on hand.

Why chimichurri is always prepared in advance

Raw chimichurri — what we call chimichurri fresco — needs time. Not two hours, not all night. Thirty minutes minimum, one hour is better. During this time, the olive oil infuses with the parsley, the garlic loses its aggressive edge, and the vinegar binds everyone together. Hand-chopped, not in a blender — you want pieces, not a green puree. The aroma rising from the bowl as you mix is already a promise: parsley, raw garlic, a slight vinegary acidity. If you taste it immediately after mixing, it’s sharp and unbalanced. Let it sit. That’s where the magic happens.

The part everyone misses: cooking the sausage

Merguez is cooked slowly. This is where everyone fails — a barbecue that’s too hot, sausage burnt on the outside and cold on the inside. You need two cooking zones: a high-heat zone to sear the skin, a gentler zone to finish. Two to three minutes over direct embers so the skin blisters and turns that deep mahogany color, then ten minutes in indirect heat so the meat cooks without drying out. When you prick it with a fork and the juice that comes out is clear — not pink — it’s ready. Resist the urge to poke it too early.

The bread needs to be toasted too

Not optional. Toasted bread is the boundary between a good choripan and an ordinary sandwich. Thirty seconds crumb-side down on the hot grill, just long enough for the surface to turn golden like light caramel and for the ciabatta holes to crunch slightly under your fingers. This toasted layer absorbs the sausage juices without getting soggy — it holds. And it adds that slightly smoky background that harmonizes perfectly with the chimichurri herbs.

Assembly: two seconds, no more

Don’t overthink it. Sausage in the bread, two spoonfuls of chimichurri on top. That’s it. Eat immediately, standing up if possible, because the choripan is a street sandwich before it’s a sit-down meal. The chimichurri will drip down the sides, the sausage juice will slightly soak the bottom bread — that’s exactly what’s supposed to happen. Have napkins ready.

Tips & Tricks

Don’t cut the sausage in half lengthwise to speed up cooking — you’ll lose all the juices inside, and the merguez will end up dry. Leave it whole on the grill for even cooking.
If you make the chimichurri the day before and put it in the fridge, take it out 20 minutes before serving: olive oil slightly solidifies in the cold and the sauce loses its vibrancy. At room temperature, it regains its fluid texture and aromas.
Adjust the amount of red chili flakes to your tolerance — a pinch just gives depth, a full teaspoon and you’ll start feeling the heat rise. Start light, taste, and adjust.

FAQs

Can I prepare the chimichurri in advance?

Yes, it’s even recommended. One hour of infusion is enough for the flavors to blend, but you can make it the day before and keep it in a closed jar in the refrigerator. Take it out 20 minutes before serving so it regains its fluid texture — olive oil solidifies slightly in the cold.

Can I cook the merguez without a barbecue?

Absolutely. A dry-heated cast iron skillet works very well: sear the merguez for 2-3 minutes on high heat to color them, then lower to medium heat, cover, and continue cooking for 8-10 minutes. The oven grill at 220°C also works, turning halfway through.

What can I substitute for lamb merguez?

Spicy beef sausage or poultry sausage with fennel are excellent alternatives. To stay in the Argentine spirit, look for a smoked beef sausage at a butcher. Smoked plant-based sausages also work surprisingly well with the herbaceous chimichurri.

Is choripan eaten with anything other than chimichurri?

In Argentina, some people add a salsa criolla — a brunoise of tomatoes, onions, and peppers seasoned with vinegar. But traditionally, choripan is eaten only with chimichurri. Resist the urge to add mustard or ketchup.

How to store leftovers?

Chimichurri keeps for up to 5 days in the refrigerator in an airtight jar. Cooked merguez keeps for 2 days in the cold, but is truly best freshly grilled. Reheat them in a pan rather than the microwave, and always keep the bread separate.

How to dose the chili in the chimichurri?

Start with a small pinch and taste before adding more — the chili is felt more after infusing than right after mixing. For a group with mixed tastes, serve the chili on the side so everyone can adjust in their own bowl.
