Preheat and prep: Preheat the oven to 200°C / 400°F for the carrots. Pat the beef dry with paper towels and season generously with salt and black pepper — patting dry is essential to get a good sear (moisture on the surface steam‑cooks the meat instead of browning). Toss the carrot slices with 1 tbsp olive oil and a pinch of salt; spread in a single layer on a rimmed baking sheet.

Roast the carrots (why: concentrating sweetness and adding a caramelized note): Roast the carrots in the preheated oven for 18–22 minutes, turning once, until they are tender and have some browned edges. Roasting caramelizes the natural sugars and gives a counterpoint to the savory braise.

Toast the nuts and bloom spices: While the carrots roast, warm a small dry skillet over medium heat and toast the almonds/pine nuts for 2–3 minutes until fragrant and lightly golden — watch closely to prevent burning. Set aside. In the same skillet toast the ground cumin, cinnamon and smoked paprika for 20–30 seconds — toasting briefly in dry heat (or a teaspoon of oil) blooms the spices and deepens their aroma.

Sear the beef (why: Maillard reaction builds flavor): Heat a large heavy skillet or Dutch oven over medium‑high heat and add 2 tbsp olive oil. When the oil is shimmering, add half the beef in a single layer and sear without moving for 1½–2 minutes per side until well browned. Work in batches to avoid crowding (crowding steams the meat). Remove seared beef to a plate and repeat with remaining beef.

Sweat aromatics and develop the base: Lower the heat to medium. Add the chopped onion and a pinch of salt to the pot and cook, stirring, 5–7 minutes until softened and starting to color — the browning adds sweet, savory depth. Add the minced garlic and the toasted spices and cook 30–45 seconds until very fragrant (this wakes up the spices).

Deglaze and build the braising liquid (why: lift all the fond and concentrate flavor): Pour in about ½ cup of the stock and use a wooden spoon to scrape the browned bits (fond) off the bottom of the pan — this is flavorful glue for the sauce. Return the beef and any collected juices to the pot, add the remaining stock and the soaked raisins (drained). Bring to a gentle simmer.

Braise gently to tenderize: Reduce heat to low, cover partially (lid slightly off or tilted) and simmer gently for 35–45 minutes until the beef is tender. Thinly sliced chuck or very lean strips may be done closer to 30–40 minutes; thicker or chewier cuts can need up to an hour. Low, steady braising at just below a simmer breaks down connective tissue and keeps meat moist.

Finish braise for flavor balance: Taste the braising liquid and adjust seasoning — preserved lemon is salty and bright, so add salt sparingly. Stir in the finely chopped preserved lemon rind and simmer 2–3 minutes to meld the bright citrus essence through the sauce (we use rind because the pulp can be intensely salty and bitter). If the sauce is too thin, raise heat and reduce 3–5 minutes to intensify.

Prepare the couscous (why: gentle finishing keeps grains fluffy): While the braise finishes, reheat or cook your Moroccan couscous if needed. If using prepared/cooked couscous (2 cups), warm it gently in a covered saucepan with a pat of butter (1 tbsp) and 1 tbsp olive oil to keep grains separate and glossy. Fold in half the chopped herbs (cilantro and parsley), half the preserved lemon, and half the toasted nuts and raisins. Taste and adjust — the preserved lemon should lift the couscous, not overpower it.

Plate and finish: Spoon the preserved‑lemon couscous onto warmed plates. Arrange roasted carrots alongside or atop the couscous. Spoon braised beef and some braising sauce over the couscous. Scatter the remaining chopped herbs and toasted nuts over the dish and finish with a drizzle of the remaining olive oil for shine and silk.

Rest and slice note (if using larger pieces): If you used thicker pieces of chuck instead of thin strips, let the meat rest 5–10 minutes before slicing against the grain — resting preserves juices and slicing against the grain shortens muscle fibers for a more tender bite.

Serve: Serve immediately with extra preserved lemon on the side and freshly cracked black pepper. Offer lemon wedges or a small bowl of harissa for anyone who wants extra heat.
