“Fish, glorious fish! I am a huge fan of all seafood and am trying to include more fish in my diet. A well-cooked piece of fish needs nothing more than a little salt and acidity (like lemon juice) to make a satisfying, healthy dinner (along with some high fibre, keto-friendly vegetables of course). These sea bass fillets have a lovely crispy skin and melt-in-the-mouth flesh, but you can use any fish that you like. I had some fun playing around with a flavoured butter to accompany my fish, so I combined softened butter with chili powder, lime juice and salt, before setting in the fridge and slicing cute discs to melt over. (You could also use cayenne pepper and you can adjust the amount to your liking) Be sure to check out Side Dish ideas on the site to serve alongside the fish for the perfect keto dinner.” – Monya

More on Sea Bass with Chilli Lime Butter…
Sea bass is a delicious and nutritious choice for individuals following the ketogenic diet. It is an excellent source of high-quality protein and heart-healthy omega-3 fatty acids. These essential nutrients not only support muscle growth and repair but also help maintain optimal brain and cardiovascular health.

FOLLOW MONYA:
Moreover, sea bass is naturally low in carbohydrates, making it an ideal choice for those seeking to minimize their carb intake while still enjoying a flavourful meal.
To enhance the taste of sea bass while staying keto-friendly, a flavoured butter can be prepared. I used lime and chili powder to create a zesty and spicy infusion that pairs well with the mildness of sea bass. The citrusy notes from the lime provide a refreshing contrast, while the hint of chili powder adds a subtle kick to the dish.

It is important to note that to maintain ketosis, it’s essential to track carbohydrate intake and ensure it aligns with your daily macro goals. Consulting with a healthcare professional is advised before making significant dietary changes.

Sea Bass with Chilli-lime Butter
Per serving
Equipment
Ingredients
For the butter
- 30 g (1.1 oz) unsalted butter, softened (room temp)
- generous pinch chili powder
- 1 TB fresh lime juice
- generous pinch salt
For the fish
- 2 boneless sea bass fillets
- salt and white pepper
- 15 g (0.5 oz) unsalted butter
To finish
- finely grated lime zest
Instructions
- Start with the butter, as it requires an hour in the fridge to set. (Even better if you can make it the day before and save you time). Simply mix together the softened butter, chili powder (or cayenne pepper), lime juice and salt.
- Place the butter into the centre of square piece of clingfilm. Create a little parcel of butter, rolling the clingfilm around it and twisting the ends closed. Shape the little fat log, imagining that you will be slicing the set butter into 4 equal-size discs later once it has set. Place in the fridge for at least an hour.

- When ready to cook, pat the fish dry with good quality kitchen paper. Season both sides with salt and white pepper.
- Melt the butter (not the one you have prepared) in a non-stick pan and once hot, place the sea bass in the pan skin side-down.

- Cook until the skin is crispy, then gently turn the fish over, cooking the flesh side. Note: this does not take long, the fish will cook very quickly.
- While the fish is cooking, unwrap the butter and slice into 4 equal-sized discs.

- Serve immediately with the flavoured butter discs on top of the fish (2 per piece) and use a microplane to finely grate over fresh lime zest.
