Cod with Brown Butter and Capers (Keto)

This is a very simple fish dinner that requires only a little effort. Skinless cod fillets are very gently baked in the oven while butter is browned and infused with garlic on the stove top. After straining, I warm the butter through with little capers (which add great bursts of salty flavour) then pour it over the fish along with a generous squeeze of lemon. The night we enjoyed this, we had it with Fresh Tomato and Garlic relish which was an excellent accompaniment and highly recommended. I have not included the macros for this condiment because it is optional. However, it was sensational and I highly recommend you include it. Enjoy!

Cod with Brown Butter and Capers (Keto)

A delicious and interesting way to pimp your white fish. The capers add a good amount of saltiness and the browned butter and a squeeze of lemon make the end-result irresistible! (For my UK readers, scroll to the end of the recipe to see image ads of the products I use.)
Course Main Dish
Cuisine General
Prep Time 10 minutes
Cook Time 30 minutes
Total Time 40 minutes
Servings 4 people


  • 4 cod fillets (approx 125g / 4.4oz each), skinless and deboned
  • 1 TB olive oil
  • salt and white pepper
  • 60 g (2.1 oz) unsalted butter
  • 3 cloves garlic, peeled and smashed
  • 10 g (0.4 oz) small capers, drained (approx. 1 heaped TB)
  • 10 g (0.4 oz) unsalted butter, additional
  • freshly squeezed lemon, to finish
  • freshly snipped chives, to garnish

Optional condiment


  • Preheat the oven to 180°C (fan oven). This is 200°C for conventional ovens (or 400°F / gas mark 6).
  • Remove the cod fillets from the packaging and pat them dry with good quality kitchen paper. Place them into a tray lined with parchment paper. Season with a little salt and ground white pepper. Drizzle over the olive oil. Place into the oven for 10-12 minutes.
  • At the same time, heat the (first reference to) butter in a pan and leave to melt. Once it starts to foam, add the smashed garlic cloves and reduce the heat. Cook the garlic gently as the butter starts to 'brown', approx. 4-5 minutes. You will notice a beautiful nutty aroma as the milk solids in the butter start to brown while the garlic infuses the butter.
  • Remove the pan from the heat. Pour it into a strainer lined with muslin or cheesecloth into a small, clean pan. Discard the burnt milk solids and garlic caught in the muslin.
  • Place the clean pan of browned, garlic-infused butter on the heat over a low temperature. Add the (second reference to) butter along with the drained capers.
  • This will have melted perfectly around the same time the fish in the oven has cooked through.
  • Serve the cooked cod fillets with the browned caper butter poured over. The capers will add enough saltiness, so a crack of black pepper and a good squeeze of fresh lemon juice will finish the dish perfectly.
    If you have any herbs (I used snipped chives), scatter them over too.
  • We had ours with the Fresh Tomato and Garlic Relish (Fats of Life recipe) alongside which complemented the flavours beautifully and is highly recommended.
