Halibut with Fennel, Peppers, and Tomatoes

Look for skinless halibut fillets, or ask the person at the fish counter to remove them for you. If you end up with fillets with the skin still on, just cook them skin-side down and sprinkle the tops with the Panko.

  • Prep time: 15 minutes
  • Cook time: 30 minutes
  • Yield: 4 servings


  • 4 halibut fillets (6 ounces each)
  • 4 teaspoons lemon juice
  • Leaves from 1 sprig rosemary
  • Leaves from 2 stems thyme
  • Leaves from 2 stems basil
  • Leaves from 2 stems oregano
  • 1/2 cup Panko breadcrumbs
  • 2 teaspoons plus 2 tablespoons plus olive oil
  • 1/2 medium red onion, sliced
  • 1 bulb fennel, cored and sliced
  • 1 yellow bell pepper, seeded and sliced into strips
  • 1 orange bell pepper, seeded and sliced into strips
  • 4 Roma (plum) tomatoes, halved lengthwise and cut into strips
  • 1/2 cup pitted Kalamata olives
  • 3 tablespoons chopped parsley (to garnish)
  • 1 lemon, quartered (to garnish)

Special equipment:


1 Prep the fish: Preheat the oven to 425° F. Place the halibut fillets on a large plate and season both sides with salt and pepper. Sprinkle each fillet with 1 teaspoon lemon juice.

2 Prep the herbs and Panko: Combine the herbs on a cutting board and coarsely chop. In a small bowl, combine the Panko, 2 teaspoons of the oil, and a pinch each of salt and pepper.

3 Cook the vegetables: In a large, oven-proof skillet, heat the remaining 2 tablespoons of oil over medium heat. Add the onion and cook for 3 to 4 minutes, or until it begins to soften. Add the fennel and bell pepper slices, and cook for 5 minutes. Add the tomatoes, olives, and the chopped herbs. Cook for 3 minutes. Salt and pepper to taste.

4 Bake the fish: Place the fish fillets on top of the vegetables in the skillet. Sprinkle each fillet with 2 tablespoons of the Panko mixture.

Place the skillet in the oven and bake for 6 minutes. Check the fish: if the panko is browning too quickly, place a piece of aluminum foil loosely on top of the fish.

Bake another 6 to 9 minutes (12 to 15 minutes total), until the center of the fish is opaque when probed with a small knife. If you have an instant read thermometer, the temperature of the center of the fish should register a 135°F.

    Is the fish to be baked skin-side up?
    Is the fish to be panko’ed on both sides?

    I have very little experience with fish. Thanks so much for saying to what temperature it should be baked!

    Thank you for this recipe.

      Hi, Art! Emma here, managing editor for Simply Recipes. Look for skinless fillets; if you can’t find skinless, then bake them skin side down. Just put panko on the top. Enjoy!

    This recipe came out great! I did substitute haddock for the halibut because it was so much cheaper! I also added green beans and feta on the side.

    I like your comment about your mom and summer. Where I grew up the second Tuesday of July was Fair Day. My Mom always said that was the last day of summer. She would never give a reason for thinking that. Thanks for jogging my memory. I am looking forward to giving this fish a try. Sounds great all flavours I like.
