Easy Roasted Fish al Pastor Recipe: A Flavorful Twist 2026

Ingredients

Scale

1.5 lbs White Fish Fillets (Cod, Tilapia, or Mahi-Mahi work best)
3 tbsp Achiote Paste (look for authentic annatto-based paste)
1 cup Pineapple (fresh cubes are essential for searing)
1/4 cup Fresh Lime Juice (use freshly squeezed for brightness)

2 tbsp Olive Oil (extra virgin preferred for flavor)

Cook Mode Prevent your screen from going dark

Instructions

Whisk the achiote paste, olive oil, and fresh lime juice together in a medium glass bowl until smooth.
Coat each fish fillet thoroughly with the marinade, ensuring every side is covered for maximum flavor.
Refrigerate the fish for at least thirty minutes to allow the spices to penetrate the fillet surfaces.
Preheat your oven to 400 degrees Fahrenheit while the fish marinates in the refrigerator.
Place the marinated fish on a baking sheet lined with high-quality parchment paper or foil.
Scatter the fresh pineapple cubes around the fish to create a beautiful presentation for your Roasted Fish al Pastor recipe.
Roast the fish for 12 to 15 minutes, or until it flakes easily with a fork at the thickest point.
Remove the tray from the oven carefully once the fish is opaque and fully cooked through.
Garnish the finished Roasted Fish al Pastor recipe with freshly diced white onion and vibrant green cilantro.
Serve immediately while the dish is hot to experience the optimal texture of the Roasted Fish al Pastor recipe.

Notes

Ensure your oven is fully preheated before putting the fish in; a hot oven is critical for the Roasted Fish al Pastor recipe to develop a slight char. Use a meat thermometer to check for doneness; white fish should reach an internal temperature of 145 degrees Fahrenheit for safety. Dry the fish fillets with paper towels before applying the marinade; this allows the Roasted Fish al Pastor recipe flavors to cling better. Balance the acidity by adding a touch of agave nectar or honey to the marinade if you find the achiote paste too earthy. Do not overcrowd the baking sheet; allow enough space for the hot air to circulate around the fish and pineapple for even cooking.
