Instructions

  1. Adjust rack to top position and preheat oven to 425°F. Wash and dry produce. Dice potatoes into ½-inch pieces. Place in a medium pot with enough salted water to cover by 2 inches. Bring to a boil and cook until tender, 10-15 minutes. Reserve 1 cup potato cooking liquid, then drain and return potatoes to pot. Cover to keep warm.
  2. While potatoes cook, trim green beans if necessary. Peel and mince or grate garlic. Quarter lemon.
  3. Toss green beans on a baking sheet with a drizzle of oil, half the garlic, salt and pepper. Roast on top rack for 10 minutes. Once green beans have roasted 10 minutes, remove sheet from oven. Carefully sprinkle almonds over green beans. Return to top rack and roast until green beans are tender and almonds are browned and fragrant, 2-5 minutes more.
  4. While green beans roast, pat barramundi dry with paper towels. Season all over with salt and pepper. Heat a large drizzle of oil in a large, preferably nonstick, pan over medium-high heat. Add barramundi, skin sides down and cook until skin is crispy, 4-5 minutes. Flip and cook until barramundi is opaque and cooked through, 2-3 minutes more. Turn off heat; transfer to a plate. Wipe out pan and let cool 2 minutes.
  5. To pot with potatoes, add sour cream and mash until smooth and creamy, adding splashes of reserved potato cooking liquid as needed. Taste and season with salt and pepper if desired.
  6. Melt 2 TBSP butter in pan used for barramundi over medium-low heat. Add basil paste, remaining garlic and juice from one lemon wedge. Cook, whisking constantly, until fully incorporated and warmed through, 1-2 minutes.
  7. Divide mashed potatoes, barramundi and green beans amandine between plates in separate sections. Drizzle basil sauce over barramundi and serve with any remaining lemon wedges on the side.

Recipe Tips

For extra crispy skin, make sure the barramundi fillets are patted very dry before seasoning.

If you don’t have basil paste, substitute 2 tablespoons finely chopped fresh basil mixed with 1 teaspoon olive oil.

Reserve more potato cooking liquid than you think you need; it helps achieve the perfect creamy consistency.

FAQ

Can I use a different fish instead of barramundi?

Yes, you can substitute other firm white fish like cod, halibut or sea bass. Adjust cooking time as needed.

How do I store leftovers?

Store components separately in airtight containers in the refrigerator for up to 2 days. Reheat gently to avoid overcooking the fish.

Can I make this dairy-free?

Yes, use dairy-free sour cream and substitute the butter with a plant-based alternative. The sauce may have a slightly different flavor.
