Steps

Before you start
  • Preheat your air fryer to 400°F (200°C) for 3 minutes
  • Have vegetable broth or water at hand for the couscous
  • Measure out all ingredients before you begin—the cooking moves quickly
  1. Preheat and prepare radishOven 400°F / 205°C

    • Preheat your air fryer to 400°F (200°C) for 3 minutes.
    • While it heats, use a sharp knife to cut the watermelon radish into ½-inch (1.3 cm) thick wedges, keeping the skin on for visual drama.
    • You should have roughly 8–10 wedges.

    Tip: Keep the skin intact so the radish holds together and creates that stunning striped interior on the plate.

  2. Coat and roast radishOven 400°F / 205°C

    • In a small bowl, combine the watermelon radish wedges with 2 tbsp (30 ml) olive oil, ½ tsp (3 g) sea salt, and a few grinds of black pepper.
    • Toss gently to coat evenly.
    • Arrange in a single layer in your air fryer basket, flat side down.
    • Air fry at 400°F (200°C) for 12–15 minutes, shaking the basket halfway through, until the edges are caramelized and the flesh is tender when pierced.
    + Show details

    Ready when: Edges are golden brown and flesh yields to a fork; skin is lightly charred

    Tip: Don't crowd the basket—radishes need air circulation to caramelize rather than steam. Work in batches if necessary.

  3. Toast couscous

    • While the radish roasts, warm 1 tbsp (14 g) butter in a medium saucepan over medium heat.
    • Add 1 cup (180 g) pearl couscous and stir constantly for 2–3 minutes until lightly golden and fragrant, then pour in 1.5 cups (360 ml) vegetable broth.
    + Show details

    Ready when: Couscous is light golden and smells nutty

    Tip: Toasting the couscous in butter first adds depth—don't skip this step.

  4. Simmer couscous

    • Bring the broth to a gentle simmer, then reduce heat to medium-low.
    • Cover and cook for 8–10 minutes until the liquid is absorbed and the couscous is tender with just a slight firmness in the center.
    • Let it rest, covered, for 2 minutes off the heat.
    + Show details

    Ready when: All liquid is absorbed; pearls are plump and tender but retain slight bite

    Tip: Resist the urge to stir while simmering—stirring releases starch and makes the couscous mushy.

  5. Fluff and assemble

    • Fluff the couscous with a fork and divide among four serving bowls or plate as a bed.
    • Arrange the roasted watermelon radish wedges on top, then scatter 3 tbsp (30 g) dukkah spice blend over everything.
    • Top with ½ cup (60 g) chopped roasted pistachios and ¼ cup (10 g) torn fresh mint.
    + Show details

    Tip: Sprinkle the dukkah just before serving so it stays crunchy and doesn't absorb moisture.

  6. Finish with lemon zest (optional)

    • If using, zest a lemon over the finished dish for a bright citrus note that complements the earthiness of the dukkah.

    Tip: A microplane makes quick work of zesting without bitter white pith.

Good to know

Tips
  • Watermelon radishes are increasingly available at farmers markets and specialty grocers in spring and fall; if you cannot find them, any heirloom radish variety will work (they all roast beautifully and sweeten as they cook).
  • Dukkah is a traditional Egyptian spice blend typically made from hazelnuts or chickpeas, sesame seeds, and warm spices; look for it in Middle Eastern markets or online, or make your own by toasting and grinding nuts and spices together.
  • The air fryer's dry heat brings out the natural sugars in the radish, creating deep caramelization that wouldn't happen as quickly in a conventional oven—this is why the air fryer method is ideal here.
  • Serve this as a standalone vegetarian side, or pair it with roasted lamb, grilled fish, or charred chicken for a complete Mediterranean meal.
Make ahead

You can toast and cook the couscous up to 2 hours ahead; store it covered in the fridge. Reheat gently in a covered saucepan over medium-low heat with a splash of broth, stirring gently. Roast the radishes no more than 30 minutes before serving so they stay warm and crispy-edged.

Storage & reheating

Store leftover assembled dish in an airtight container in the refrigerator for up to 2 days, though the dukkah will soften. Reheat the couscous and radishes separately in a low oven (300°F / 150°C) for 5 minutes. Store couscous alone for up to 3 days, covered in the fridge. Does not freeze well due to the delicate radish texture.

Substitutions
  • watermelon radish → Baby carrots or beets. Both roast beautifully in the air fryer with similar caramelization. Adjust cooking time to 10–12 minutes depending on size.
  • pearl_couscous → Farro or bulgur wheat. Both have a similar texture. Increase cooking time to 12–15 minutes and use 1.75 cups (420 ml) broth for the same amount.
  • dukkah spice blend → Za'atar or a simple spice blend of ground hazelnuts, sesame seeds, coriander, and cumin. These provide similar warm, nutty, herbal notes. Use the same 3 tbsp (30 g) amount.
  • roasted salted pistachios → Toasted almonds or walnuts. Chop them to a similar size for texture. The flavor profile will shift slightly but remain delicious.
