Baked Fish with Orange-Chili Marinade

Baked fish with orange-chili marinade is the kind of weeknight seafood that tastes like restaurant-level technique without the fuss. Fresh orange juice does the same job for fish that lemon juice does for chicken: brightening, tenderizing, and adding a citrus backbone that lifts the natural sweetness of the fillets. The smoky heat from a chipotle (or two if you like it spicier) plays against the citrus in a way that’s classic Latin-American flavor pairing, while cilantro and garlic round it all out.

A 1-hour marinade is the sweet spot for fish. Any longer and the citrus acid starts to ceviche the flesh, turning it opaque and chalky before it even hits the oven. High oven heat then cooks the fillets fast and direct, using the 12-minutes-per-inch rule that works reliably across most thicknesses.

Pro Tips

• Use thick fish fillets, ideally 1 inch or more. Thin fillets dry out at high heat; thicker pieces stay moist.
• Pat fish dry before marinating. Wet fillets dilute the marinade and won’t pick up flavor properly.
• Discard the used marinade. It’s been in contact with raw fish so it’s not safe to spoon over the cooked fillets.
• Measure thickness at the thickest point and round up. Underdone fish is unsafe; slightly overdone is just dry.

Variations

• Sub salmon, mahi-mahi, or halibut depending on availability and budget.
• Swap chipotle for fresh jalapeño for cleaner heat without the smoke.
• Reserve a portion of the marinade before adding the fish, then spoon that fresh portion over rice or warm tortillas to serve alongside.
