In this keto dish, baking salmon fillets at a low temperature keeps the flesh tender and moist even when cooked to well-done. The yogurt sauce on top helps insulate the salmon too, creating a flavorful creamy coating for the fish, which is balanced with salty, crunchy cucumbers and cashews.
Green Curry and Yogurt-Roasted Salmon
Heat the oven to 325 degrees. Line a rimmed baking sheet with foil.
Place the salmon fillets on the prepared baking sheet and season all over with salt and pepper. In a small bowl, whisk together the yogurt, olive oil and curry paste until smooth, then spoon evenly over the fillets, spreading each to completely cover the tops of the salmon. Bake until an instant-read thermometer inserted in the thickest part of each fillet reads 160 degrees, about 35 minutes for 1- to 1 ½-inch-thick fillets.
While the salmon bakes, heat a small skillet over medium-high heat. Add the cashews and cook, tossing occasionally, until toasted and warm, about 2 minutes. Transfer to cutting board and roughly chop.
Place the cucumber slices in a medium bowl, sprinkle with salt and pepper and let stand, massaging occasionally with your fingers, until soft, at least 30 minutes.
Remove the salmon from the oven and transfer each fillet to a plate. Scatter the cashews over the top of each fillet and serve with cucumbers on the side.
