Step 1

Preheat the oven to 400F degrees.

Step 2

In a baking dish, drizzle half the amount of olive oil to coat the bottom completely. Top with sliced onions scattered all over the bottom of the dish.

Step 3

To prep the fish, pat it dry using paper towels and place it in the baking dish. Rub the entire fish with the rest of the olive oil.

Step 4

Squeeze half of the lemon on top of the fish. Then coat it with salt, pepper, garlic powder, cumin, and lemon zest. Make sure you sprinkle all the seasoning inside the fish as well. Place the sliced half of the lemon inside the fish.

Step 5

Bake the fish for 10 minutes. While it's baking make the tahini sauce. Mix the tahini, lemon juice, garlic, coriander, cayenne, salt and water until well combined.

Step 6

Remove the fish from the oven and cover in most of the sauce and jalapenos. Leave some of the sauce for serving. Bake for another 8-10 minutes, or until the fish is tender and registers at 145F degrees.

Step 7

Remove from the oven and top with fresh cilantro and toasted nuts.

Step 8

Serve warm over a bed of turmeric rice or saffron rice.
