Instructions

  1. Adjust an oven rack to the top position and preheat the oven to 425°F. Wash and dry all produce. Cut the broccoli into bite-size pieces. Finely chop the cilantro. Zest the lemon, then quarter it. Mince or grate the garlic.
  2. On a foil-lined baking sheet, toss the broccoli with a drizzle of oil, salt and pepper. Roast on the top rack until browned and tender, 15-20 minutes.
  3. While the broccoli roasts, in a small bowl, combine the cilantro, half the cumin, half the lemon zest, 2 tablespoons olive oil (4 for 4 servings), a big squeeze of lemon juice and a pinch of garlic to taste. Season with salt, pepper and chili flakes to taste. Set aside.
  4. In a small pot over medium-high heat, melt 1 tablespoon butter (2 for 4 servings). Add the couscous and remaining garlic. Cook, stirring often, until the garlic is fragrant and the couscous is lightly toasted, 1-2 minutes. Stir in 1 cup water (2 for 4 servings) and the veggie stock concentrate. Bring to a boil, then cover, reduce heat to low and cook until the couscous is tender, 6-8 minutes. Keep covered off heat until ready to serve.
  5. While the couscous cooks, pat the barramundi dry with paper towels. Season all over with the remaining cumin, salt and pepper. Heat a drizzle of oil in a large nonstick pan over medium-high heat. Add the barramundi and cook until opaque and cooked through, 4-6 minutes per side. Turn off the heat.
  6. Fluff the couscous with a fork and season with salt and pepper. Toss the roasted broccoli with the remaining lemon zest. Divide the couscous, broccoli and barramundi among plates. Spoon the cilantro sauce over the barramundi. Serve with any remaining lemon wedges on the side.

Recipe Tips

For the best flavor, use fresh cilantro and lemon. Adjust the chili flakes to your spice preference.

Pat the barramundi very dry before seasoning to ensure a nice sear.

If you can’t find barramundi, substitute with any firm white fish like sea bass or cod.
