Are you ever going to look good making this one. Your guests will be so impressed they won’t know what hit them. Be prepared for someone to cry foul and accuse you of bringing in a ringer for the dinner. Actually, preparing this halibut is not as difficult as if might seem at first glance. So read through the recipe closely — read it twice, just to be sure — and have everything ready before you start cooking.
Beat the egg yolks with a little salt and pepper in a shallow pan, a pie pan works great, to make an egg wash.
Combine the potato flakes with the thyme leaves and spread out on a plate or shallow pan.
Season the fillets with salt and pepper on 1 side.
Dip just the seasoned side of the fish into the egg wash, being careful not to let any egg wash drip down the sides of the fish.
Dip the egg-washed side of the fish into the seasoned potato flakes and press down a bit to make them adhere. Set aside, crust-side down.
Repeat with the remaining fillets.
Pour the olive oil into a large sauté pan, arrange the fillets crust-side down in the pan, and place on the burner over medium-high heat. Do not preheat the sauté pan.
After about 3 minutes, the crust should be golden brown, if it is not, raise the heat to high and continue cooking.
When the crust has turned golden brown, season the fish with salt and pepper, flip it over and cook for 1 minute.
Remove from heat and leave the fillets in the pan for 1 minute.
Deglaze the pan with the lemon juice, being careful not to squeeze it directly on the fish, which would soften the crisp crust you have worked so hard to develop. Swirl the pan a few times to incorporate the lemon juice.
Remove the fish from the pan and serve!
