In this tutorial, we learn how to cook a halibut filet with Dan Hernandez. To start, you will need to heat up your pan with oil on the inside of it until it's hot. While this is heating, combine salt, pepper, garlic, and crushed onions on a bowl and mix it together thoroughly. After this, apply the spice to the filet and push inside of it. Now, place the filet with the season side down onto the oil and cook until golden brown on this side. Meanwhile, make a sauce with flour, salt, milk, cheese, and cream in another pan. Once the filet is cooked on side, turn on the other and continue to cook until all the way finished. Then, serve the fish with the sauce over it and enjoy!
