Ingredients
Instructions
- Adjust racks to top and middle positions and preheat oven to 425°F. Wash and dry produce. Dice potatoes into ½-inch pieces. Trim and thinly slice scallions, separating whites from greens. Zest and quarter lemon.
- Place potatoes in a medium pot with stock concentrate and enough salted water to cover by 2 inches. Bring to a boil and cook until tender, 15-20 minutes. Reserve ½ cup potato cooking liquid, then drain and return potatoes to pot. Mash with sour cream and 1 TBSP butter (2 TBSP for 4 servings) until smooth, adding splashes of reserved potato cooking liquid as needed. Season generously with salt and pepper. Keep covered off heat until ready to serve.
- While potatoes cook, cut broccoli into bite-size pieces if necessary. Toss on a baking sheet with a drizzle of oil, salt and pepper. Roast on top rack until golden brown and crispy, 15-20 minutes.
- While broccoli roasts, pat barramundi dry with paper towels. Rub each fillet with a drizzle of oil. Season generously all over with salt and pepper, then rub paprika into flesh sides. Heat a large drizzle of oil in a large, preferably nonstick, pan over medium-high heat. Add barramundi, skin sides down; cook until skin is crispy, 3 minutes. Turn off heat. Transfer barramundi, skin sides down, to a second lightly oiled baking sheet. Roast on middle rack until cooked through, 10-12 minutes.
- Meanwhile, heat pan used for barramundi over medium heat. Add 2 TBSP butter (4 TBSP for 4 servings) and scallion whites. Cook, carefully swirling butter, until foamy and flecked with amber brown bits, 2-3 minutes. Turn off heat and add a big squeeze of lemon juice. Stir in lemon zest; season with salt and pepper.
- Divide mashed potatoes, barramundi and broccoli between plates. Top potatoes and barramundi with brown butter and sprinkle with scallion greens. (TIP: If brown butter is done before the rest of the meal, reheat over low heat, stirring, for 1 minute.) 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 a potato masher, use a fork or the back of a spoon to mash the potatoes.
The brown butter can be made ahead and reheated gently over low heat.
