While I have yet to post a black cod (sablefish) recipe on my blog, it actually happens to be one of my favourite fish varieties!

I often purchase it for special occasions (or when it’s on sale) because it has SUCH a beautiful and luxurious taste and texture. That said, this recipe is perfect for a healthy weeknight dinner!

This baked black cod recipe is a super simple, yet flavourful way to cook sablefish in the oven. It’s only 10 ingredients and packed with Mediterranean flavours!

As a dietitian, I’m happy to share that black cod has plenty of nutrition benefits (covered below). This dish is also a great source of veggies, and I’ve included some serving ideas for making this recipe a complete meal as well. Enjoy 🙂

Recipe Modifications & Ingredient Swaps

  1. You could try making this recipe with a different type of fish, like regular cod, halibut, or even salmon. Please note that cooking times may differ depending on the type of fish and on the thickness of the cut! A quick Google search for cooking your specific fish variety should do the trick 🙂
  2. Feel free to use only one type of olive here, instead of both green and black (if desired). My personal preference would be to go for the green ones!
  3. If you want to try adding some chopped shallots or onions, that would likely work well too.

What To Serve This Recipe With

As this sablefish recipe is a delicious mix of protein, healthy fats, and fiber-rich veggies, I would recommend serving it with a type of starch to make a complete meal! Some ideas:

  • whole grains, like quinoa, farro, millet, or brown rice
  • boiled or roasted potatoes (I love using mini ones!)
  • pasta (the veggie mixture would make great, light sauce!)

Ingredients

  • 1 pound black cod fillets (450g; cut into 4 pieces)
  • 1 large bell pepper, cored + chopped (red, orange, or yellow)
  • 1 cup cherry tomatoes, halved
  • 5 large green olives, pitted + diced (I used Gordal)
  • 8 small black olives, pitted + diced (I used Hojiblanca)
  • 2 large cloves garlic, minced
  • 1/4 cup parsley, chopped
  • 2 Tbsp olive oil
  • 1 lemon, juice only
  • Salt + pepper, to taste
  • Fresh basil, chopped (to garnish)

Instructions

  • Preheat oven to 400F.
  • Place sablefish fillets in a large baking dish.
  • In a large bowl, toss together the peppers, tomatoes, olives, garlic, parsley, olive oil, lemon juice, salt, and pepper.
  • Pour vegetable mixture over top of fish fillets. Spread out evenly so that the fish is visible and the vegetable mixture surrounds it. Season fish with additional salt and pepper.
  • Place baking dish in the oven for about 20 minutes, or until desired doneness (for the fish).
  • Remove from oven and garnish with fresh basil. See notes for some serving ideas!
