Substitutions and Ingredient tips

The Fish

Using a mild flavoured white fish and cooking it quickly makes this dish not too fishy! I love it with Ling fillets or Basa personally.

All the other ingredients are straight forward – but as always, fresh is best! If you can bothered to crush your own garlic it gives it a lovely mild flavour.

I like to serve this with cauliflower mash as pictured, but you can really use whatever side dish you preffer.

Tips for making Keto Baked Fish with Lemon Butter

Can you believe that this Keto Baked Fish with Lemon Butter takes only 20 minutes to prepare. Here are the steps:

  • Preheat oven to 220C / 428F. Line a baking dish with baking paper. 
  • Finely grate the rind of one lemon and cut half of it into small segments. 
  • Pat dry fish then season with salt and pepper. Drizzle with olive oil and half the grated lemon rind. Place in the oven and bake for 12 – 14 minutes until just falling apart and cooked through. 
  • Steam the broccolini in the microwave until just tender (around 4 mins). Drain and set aside to dry.
  • Meanwhile, in a frying pan heat the butter over medium heat until just turning golden, around 3 – 4 minutes. Add the remaining half lemon rind and garlic and cook for a further 1 minute. Stir in the lemon segments and steamed broccolini. 
  • Serve the fish topped with broccolini and lemon sauce on a bed of cauliflower mash. 

One tip: This can be easily served with broccolini but just as great with beans or asparagus. Serve on a bed of creamy cauliflower mash to soak up the sauce.
