This vibrant dish brings together tender barramundi fillets with a bright, herbaceous chimichurri sauce. The sauce-made with cilantro, garlic, lemon, cumin and chili flakes-adds a punchy, tangy flavor that perfectly complements the mild, buttery fish.
On the side, we’re serving fluffy garlic butter couscous and roasted carrots tossed with fresh lemon zest. Every bite is a harmony of fresh, bold flavors that will make this a new weeknight favorite.

Ingredients
Instructions
- Adjust rack to top position and preheat oven to 425°F. Wash and dry produce. Trim, peel and cut carrots on a diagonal into ½-inch-thick pieces. Finely chop cilantro. Zest and quarter lemon. Peel and mince or grate garlic.
- Toss carrots on a foil-lined baking sheet with a drizzle of oil, salt and pepper. Roast on top rack until golden brown and softened, 20-25 minutes.
- While carrots roast, in a small bowl, combine cilantro, half the cumin (you’ll use the rest later), half the lemon zest, 2 TBSP olive oil (4 TBSP 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 chimichurri aside.
- Heat 1 TBSP butter (2 TBSP for 4 servings) in a small pot over medium-high heat. Add couscous and remaining garlic. Cook, stirring often, until garlic is fragrant and couscous is lightly toasted, 1-2 minutes. Stir in ¾ cup water (1½ cups for 4) and stock concentrate. Bring to a boil, then cover and reduce to a low simmer. Cook until al dente, 6-8 minutes. Keep covered off heat until ready to serve.
- While couscous cooks, pat barramundi dry with paper towels. Season all over with remaining cumin, salt and pepper. Heat a drizzle of oil in a large, preferably nonstick, pan over medium-high heat. Add barramundi and cook until opaque and cooked through, 4-6 minutes per side. (Barramundi is fully cooked when internal temperature reaches 145°F.) Turn off heat.
- Fluff couscous with a fork; season with salt and pepper. Toss carrots with remaining lemon zest. Divide couscous, carrots and barramundi between plates. Top barramundi with chimichurri. Serve with remaining lemon wedges on the side.
Recipe Tips
For even roasting, cut carrots into uniform ½-inch pieces.
Toast the couscous until lightly golden for extra nutty flavor.
Pat barramundi very dry before seasoning to ensure a nice sear.

Yes, you can substitute barramundi with other firm white fish like cod, halibut or sea bass. Adjust cooking time as needed.
Can I make the chimichurri ahead of time?
Absolutely! The chimichurri can be made up to a day in advance and stored in the refrigerator. Let it come to room temperature before serving.
What can I use instead of Israeli couscous?
