Keto White Fish in Lemon Sauce

author avatar Dr. Eric Berg 08/31/2023


This is a super tasty keto recipe. It's a white fish in a creamy lemon sauce. You can use any hardy white fish, so use your favorite! If you're looking for a main dish, you've got to try this recipe out. We also use parsley in this dish. What's interesting about parsley is that it's used simply as a garnish in many recipes, but it may actually be the healthiest thing on the plate! Parsley has a certain phytonutrient that has potential anti-cancer properties. It's healthy. It's fast. It's simple. Give it a try!


  • 2 large white fish fillets (here we use Barramundi, but you can use any white fish)

  • 4 Tbsp unsalted butter

  • ¼ cup heavy cream

  • 5 cloves of garlic, minced 

  • 1 Tbsp Dijon mustard

  • 1½ Tbsp lemon juice

  • salt and pepper to taste 

  • 1½ Tbsp minced shallots

  • parsley for garnish (optional) 


Preheat the oven to 375 degrees F.

In a small saucepan over low heat, combine the cream, butter, lemon juice, mustard, salt and pepper to taste, and garlic. Mix until the butter is melted, for about 3 minutes.

Lightly grease a baking dish with butter or olive oil and lay your fish in it. Top with onions and the cream sauce. 

Bake in the oven for about 15 minutes.

Garnish with parsley and enjoy!
