• 1 teaspoon olive oil
• 1 tablespoon chopped fresh dill
• kosher salt and cracked black pepper to taste
• 1 (1 pound) halibut fillet
• 2 tablespoons chopped fresh flat-leaf (Italian) parsley
• 5 large baking potatoes, peeled and cubed
• 0.25 cup grated Parmesan cheese

Recipe Instructions

Step 1

Meanwhile, preheat the oven to 350 degrees F (175 degrees C).

Step 2

Grate cucumber into a colander and sprinkle with 1/4 teaspoon salt. Let stand for 15 minutes. Squeeze excess liquid from the cucumber.

Step 3

Combine squeezed cucumber, sour cream, yogurt, lemon juice, olive oil, and garlic in a bowl. Season with salt and pepper. Refrigerate tzatziki sauce for at least 2 hours.

Step 4

Place halibut in a lightly oiled baking dish. Pour lemon juice over top and sprinkle with salt and pepper. Rub fillet, then let stand for 20 minutes.

Step 5

Top halibut with parsley and dill. Spread 1/2 of the tzatziki sauce in an even layer over fish.

Step 6

Bake in the preheated oven until fish is still moist but flakes easily with a fork, about 20 minutes.

Step 7

While the fish is baking, place potatoes into a large saucepan and cover with cold salted water. Bring to a boil over medium-high heat. Cook until potatoes are tender, about 15 minutes.

Step 8

Drain potatoes and return to the pot. Add remaining tzatziki sauce, parsley, and 1/4 cup Parmesan cheese. Season with salt and pepper to taste. Smash potatoes gently until slightly mashed, but still chunky.

Step 9

Remove halibut from the oven. Turn on the broiler.

Step 10

Top halibut with remaining 1/4 cup Parmesan. Return to the oven and broil until Parmesan has browned slightly and formed a crust, 5 to 8 minutes.

Step 11

Remove from the oven and let rest for 5 minutes. Serve alongside potatoes.
