Instructions

Whisk the achiote paste with lime juice, orange juice, and a pinch of salt until smooth.
Coat the fish fillets thoroughly with this mixture in a glass bowl.
Let the fish sit for fifteen minutes to allow the flavors to penetrate the surface of the meat.
Preheat your oven to 400 degrees Fahrenheit to ensure your Roasted Fish al Pastor recipe cooks effectively.
Line a large baking sheet with parchment paper to prevent sticking and simplify your cleanup afterward.
Arrange the marinated fillets on the tray with space between them for even heat circulation.
Scatter the diced pineapple and onions around the fish to create a flavorful base.
Roast the tray in the center of the oven for twelve minutes until the fish flakes easily.
Broil the fish for an additional two minutes if you prefer a deeper, charred crust.
Remove the dish carefully and garnish with fresh cilantro immediately before serving your finished Roasted Fish al Pastor recipe.

Notes

Use a shallow baking pan so the air circulates freely, ensuring the moisture evaporates to create a perfect glaze for your Roasted Fish al Pastor recipe. Keep the fish pieces uniform in thickness to guarantee they finish cooking at the same time and retain their delicate juiciness. Add the fresh cilantro only after removing the tray from the oven to maintain its bright color and avoid wilting. Taste your marinade before applying it; it should be bold and tangy to stand up to the mild profile of the white fish in this Roasted Fish al Pastor recipe. Consider using a meat thermometer to ensure the internal temperature reaches 145 degrees Fahrenheit, which guarantees safety and perfect texture.
