In this delicious and simple pasta recipe, halibut is “cooked” ceviche-style in a zesty lemon marinade then tossed with warm spaghetti. While the fish marinates, throw together a salad for an easy and healthy dinner.

  • 12 ounces halibut, skinned and cut in ½-inch cubes
  • 6 tablespoons lemon juice
  • ¼ cup extra-virgin olive oil
  • 3 tablespoons finely chopped red onion

  • ¼ teaspoon crushed red pepper
  • ½ teaspoon salt plus 1 tablespoon, divided
  • 1 small Yukon Gold potato (about 2 ounces)
  • 12 ounces spaghetti

  • Ready In

  1. Combine halibut, lemon juice, oil, onion, parsley and crushed red pepper in a large bowl. Season with ½ teaspoon salt and mix well. Let stand at room temperature, stirring occasionally, until the fish is opaque throughout, at least 1 hour and up to 2 hours.
  2. Place potato in a large saucepan, cover with cold water and bring to a boil. Reduce heat to medium and cook until very tender, 12 to 15 minutes. Remove the potato; peel when it's cool enough to handle. Keep the potato-cooking water and add enough water to the pot to make about 2 quarts total for cooking the pasta.
  3. When the fish is done marinating, return the water to a boil. Add the remaining 1 tablespoon salt, then stir in pasta until all the strands are submerged. Cook according to package instructions until just tender.
  4. Meanwhile, mash the potato through a ricer or with a fork. Add to the bowl with the fish and stir until well combined.
  5. When the pasta is done, drain well and toss with the fish mixture. Serve at once.

Gummy Pasta This dish was not a success in my kitchen. As individual ingredients, fish ceviche and simple spaghetti, the items would be have been better. When combined, the riced potato stuck to the pasta similar to a glue. In the photo, it also looks as though there were more red pepper flakes added -- which would be good since it needed a touch more of flavor. I would also suggest garnishing each plate with more lemon and parsley. Pros: Fresh, easy recipe Cons: Potato made pasta gooey. Fish needed more than an hour to marinate.
