I spotted several recipes in which people were riffing on Claudia Rosen’s recipe for fish baked in a tahini-lemon sauce, so I decided to try the original recipe, which is in her classic The New Book of Middle Eastern Food (which replaced my worn-out copy of her original 1972 book).
We enjoyed it with home-made pitas, but I think it would also be good with rice. This version will serve 6 and will take about 30 minutes to prepare. (The photo actually shows 2 servings minus the parsley garnish.)
2 lbs. fish fillets, cut into 6 equal pieces (I used salmon)
Salt
2 large onions, cut into thin slices
3 Tbs. extra virgin olive oil
1 cup tahini paste
½-2/3 cup fresh lemon juice
1 cup water
¼ cup chopped Italian parsley
2 lemons cut into wedges for serving.
Preheat the oven to 400 degrees.
Season the fish with salt.
In a large skillet, heat the olive oil over medium heat. Add the onions and sweat them until they are translucent, a few minutes. Remove from the heat.
Beat together in a bowl the tahini, lemon juice, and water to form a light and creamy sauce. (It will be tight at first but will loosen.) Add salt to taste.
Select a baking dish just big enough for the fish fillets to be placed in a single layer. Cover the bottom with the softened onions. Top the onions with the fish fillets. Pour over it all the tahini-lemon sauce. Bake for about 20-30 minutes until the fish flakes easily. Sprinkle with parsley and serve with lemon wedges.
