Black Gill Rockfish in Orange Cream Sauce

Rated as 4 out of 5 Stars

"My Peruvian MIL makes this dish, and it remains a favorite for the whole family (even the picky ones)! It's a delicate sauce that complements a variety of fish types. This dish in Peru is served with white rice, and I love this sauce with asparagus!"

  1. Place potatoes into a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until tender, about 20 minutes. Drain. Run potatoes under cold water until completely chilled; drain. Remove and discard potato peels. Slice potatoes into 1/2-inch rounds.
  2. Preheat oven to 300 degrees F (150 degrees C). Lightly grease small casserole dish with oil.
  3. Arrange potatoes into the prepared casserole dish; top with rockfish. Season rockfish and potatoes with pepper.
  4. Melt butter with olive oil in a large skillet over low heat. Stir flour, Greek seasoning, paprika, and salt into the butter mixture; cook, stirring occasionally, until fragrant and you have a roux that is beige in color, 5 to 8 minutes.
  5. Whisk half-and-half into the roux; cook until thickened, 3 to 5 minutes. Stir orange juice, lemon juice, and thyme into the half-and-half mixture; whisk over heat until warmed. Remove from heat and season with salt and pepper to your taste.
  6. Pour the sauce from the skillet over the potatoes and rockfish; top with the chopped orange.
  7. Bake in preheated oven until the fish is cooked through, 15 to 20 minutes. Switch oven to Broil and continue cooking until the top is lightly browned, about 10 minutes more. Cool at room temperature for 10 minutes before serving.


  • Cook's Notes:
  • Any mild, firm, thick, and pale-fleshed fish will work for this recipe.
  • Chives can stand in for the thyme in the sauce for a variation on flavor.

Yum! My only change is I used a little bit of ranch seasoning in place of Greek. The flavors are super subtle, creamy and delicious. I'd never had rockfish before. We made a second batch of rice...

The fish was amazing. The orange flavor of the sauce was exquisite. I didn't serve it with rice, but I wish I had the sauce was so good.

It was OK. I thought the sauce would have more flavor.

My wife and I enjoyed this very much. I wasn't sure if 300 degrees would be enough, so I turned the heat up to 350 or so for the last ten minutes and I kept an eye on it while broiling so I coul...
