Lemon Butter Fish – Keto & Low Carb

lemon butter fish

This lemon butter fish is one of the easiest keto-friendly fish recipes you can follow. It takes only 10 minutes to prepare, so it’s the perfect recipe to try for a quick dinner meal that does not involve meat.

As you know, fish is a very keto-friendly food. It’s packed with protein and provides a good source of vitamin B, selenium, iodine, and omega 3 fatty acids. The Omega 3 content of  white fish is a lot lower than in oily fish.

Unfortunately, not a lot of people are big fans of fish due to the smell. But, this lemon butter fish from Tanya, one of the team at KetoVale, recipe bursts with lemony butter flavor, which overpower any pungent “fishy” odor.

Fish that is very fresh should not have a fishy odor so make sure that what you buy is very fresh. White fish fillets you could use for this dish would be talapia, halibut, sole, haddock or cod.


Talapia is a very popular fish for white fish dishes but the quality varies according to whether it’s farmed or wild. Some fish farms have better practices than others so it pays to do a bit of research first.

One criticism of talapia you often hear is that the all important omega 3 ratio to omega 6 fatty acids is low. Oily fish are noted for their high healthy Omega 3 content but white fish is low in it.

It’s the omega 6 fats that many people have too much of and not enough omega 3s. Although we need both they have to be in proper balance for good health.

Omega 6 fatty acids are pro-inflammatory and Omega 3 fats are anti-inflammatory. As inflammation is at the root of many chronic diseases it pays to make sure that you have the right ratio in your cells.

For a fish dish with higher amounts of Omega 3 you could try this low carb Garlic Butter Salmon Recipe or this refreshing Keto Avocado Salmon Salad.

Lemon Butter Fish

Serves 2


  • 2 white fish fillets, as fresh as you can get them
  • 1 tbsp avocado oil
  • 3 tbsp almond flour
  • 2 tbsp grass-fed butter plus another 1 tbsp
  • ½ tbsp organic lemon juice
  • 1 tsp chopped organic parsley
  • Redmond Real Sea Salt
  • Black pepper to taste


1. First, you need to prepare the sauce. To do this, start by melting the 2 tbsp butter in a small saucepan over medium heat. Leave it until it becomes a nice nutty brown color, which should take about 3 minutes. Take care not to let it burn. Remove from heat and place in a bowl. Add the lemon juice and season with salt & pepper to taste. Keep warm.

2. Next season the fish fillets with some salt and pepper.  If you’re using skinless fillets, then season both sides. Then coat with almond flour on the skinless part patting it on.

3. Heat the avocado oil in a skillet and add the 1 tbsp butter. Once melted, fry the fish fillets gently for two minutes on each side.

4. Remove the fish from the skillet and place it onto your serving plates. Drizzle each fillet with the butter lemon sauce you prepared earlier then garnish with some chopped parsley.

5. Serve your lemon butter fish with some leafy greens or green salad.
