- 0.5 tsp (1.2g) sweet paprika
Step-by-Step Directions
- Preheat your oven to 360°F (182°C) and line a large baking sheet with a piece of parchment paper to prevent sticking.
- Arrange the 4 mackerel fillets (21.2 oz (600g)) on the prepared baking sheet, ensuring they are spaced out evenly for even heat distribution.
- Drizzle 2.0 tbsp (30ml) of olive oil and 2.0 tbsp (30ml) of fresh lime juice directly over the fish, then sprinkle with 0.5 tsp (1.2g) of sweet paprika.
- Rub the oil and seasonings gently into the flesh of each fillet using your hands or a pastry brush to ensure full coverage.
- Bake at 360°F (182°C) for 30 minutes, or until the fish is opaque and flakes easily with a fork.

Pro Tips for the Best Lime Mackerel
- Choose Freshness First: When buying fish for your Lime Mackerel, look for bright, clear eyes and shiny, metallic skin. Mackerel is an oily fish that spoils faster than white fish, so freshness is key to avoiding a "fishy" aftertaste.
- Don't Skip the Room Temp Rest: Take your mackerel fillets out of the fridge about 10–15 minutes before baking. This ensures the Lime Mackerel cooks evenly from edge to center.
- Pat it Dry: Before adding your oil and lime, pat the skin side of the mackerel with a paper towel. This helps the seasoning stick better and prevents the fish from steaming rather than roasting.
- Zest for Extra Zing: For a more intense citrus aroma, grate 0.1 oz (3g) of lime zest over the fillets before they go into the oven. The oils in the zest provide a deeper flavor than the juice alone.
Frequently Asked Questions (FAQ)
Can I use frozen fillets for this Lime Mackerel recipe? Yes, you can use frozen mackerel! Just ensure they are completely thawed in the refrigerator overnight and patted dry with a paper towel before you begin the preparation to ensure the seasoning adheres properly.
How do I know when the Lime Mackerel is fully cooked? The Lime Mackerel is done when the flesh turns opaque and flakes easily with a fork. Since mackerel is a denser fish, it should reach an internal temperature of 145°F (63°C). Be careful not to overcook it, as it can become dry quickly.
What can I substitute for sweet paprika in this dish? If you want a different flavor profile for your Lime Mackerel, you can swap sweet paprika for smoked paprika for a deeper, wood-fired taste, or use 0.5 tsp (1.2g) of chili powder if you prefer a bit of heat.
How should I store leftovers of this Lime Mackerel? Store any leftover Lime Mackerel in an airtight container in the refrigerator for up to 2 days. To reheat, place it in a pan over medium-low heat with a splash of water or extra lime juice to keep it moist.
