- Requires less cooking oil
- Produces healthier results
- Takes less than 15 minutes
The quick cooking process preserves the fish’s rich texture and prevents overcooking.
How to Choose the Best Spanish Mackerel
Fresh fish is essential for achieving the best broiled Spanish mackerel recipe.
Look for These Signs of Freshness
- Bright, shiny skin
- Firm flesh

Preparing the Spanish Mackerel
Before broiling, proper preparation helps maximize flavor and texture.
Step 1 – Clean the Fish
Rinse the fillets gently under cold water and pat dry thoroughly using paper towels.
Removing excess moisture helps the fish broil evenly and develop a beautiful crust.
Step 2 – Remove Pin Bones
Run your fingers along the flesh and remove any remaining pin bones using tweezers.
Step 3 – Score the Skin
Lightly score the skin with shallow cuts. This helps the seasoning penetrate the fish and prevents curling during broiling.

Step-by-Step Guide to Broiling Spanish Mackerel
1. Prepare the Fish
Wash the Spanish mackerel thoroughly and pat it dry with paper towels. Cut the fish into medium-sized pieces or leave it whole if preferred. Place it in a bowl and season with salt, black pepper, garlic, lemon juice, and a little olive oil. Let it marinate for 15–20 minutes for better flavor.

Turn on your oven broiler and allow it to heat for about 5 minutes. Line a baking tray with foil or lightly grease it to prevent sticking. Arrange the fish pieces evenly on the tray.

Place the tray under the broiler. Cook the fish for about 6–8 minutes on one side until slightly golden and crispy. Carefully flip the fish using tongs.
