Oven Roasted Toothfish Fillets with Shallow Fried Marrow

Patagonian toothfish, also called Chilean sea bass, is a flaky, buttery and flavoursome white fish. This deep-water fish lives in the waters around Antarctica and is rich in omega-3 fatty acids. The fishing of this species is controlled to avoid overfishing which makes it a relatively expensive product but well worth the cost.

What species is toothfish?

Patagonian toothfish is best comparable to black cod, and its alternative name of Chilean sea bass has nothing to do with a sea bass but was named as such in 1977 for marketability reasons. This ugly looking fish has sharp teeth, hence its name but the flesh is firm, flaky and slightly sweet.

We refer to this dish as a ‘lazy’ recipe as the fish just needs seasoning and then the oven does the rest of the work. We advise serving with our stress-free marrow recipe on the side as it pairs very well with the fish.  A tomato coulis adds acidic flavour and a bright appealing colour.

  • To degorge a vegetable is the process of sprinkling salt over it to eliminate excess water. Courgettes, marrows, aubergines, cucumbers, and cabbage are often salted, rinsed and patted dry before cooking.
  • Some vegetables need to be coated with starch prior to deep frying (courgettes, marrows, aubergines). This prevents the food from breaking up and preserves their shape and texture. The coating seals in the moisture and the flavour during the frying and prevents it from absorbing too much oil.
