Preparation
Step 1
Start by preparing the sauce. Use thick mayonnaise with at least 67% fat. Lemon juice thins the sauce, so if the mayonnaise is too runny, it won’t stick to the fish but will slide off. The thicker the mayonnaise, the better.
Step 2
In a bowl, mix mayonnaise, lemon juice, fish seasoning, paprika, salt, and pepper. If using a premade spice blend, check the ingredients - many already contain salt and pepper, so adjust accordingly to avoid overseasoning.
Step 3
Stir well until you get a smooth, slightly thick sauce.
Step 4
Prepare the fish. Choose a large crucian carp weighing at least 1 lb (500 g). You can use fresh or frozen fish. If frozen, thaw it properly first.
Step 5
Clean the fish by removing scales, guts, gills, and fins. Rinse thoroughly inside and out, then pat dry with paper towels. If the fish is large, make shallow cuts across both sides of the body.
Step 6
Chop the onion into small cubes or thin half-rings.
Step 7
Brush the fish inside and out with the mayonnaise sauce on all sides.
Step 8
Stuff the fish cavity with the chopped onion.
Step 9
Place the fish on a baking tray lined with foil and brush the top with the remaining sauce.
Step 10
Wrap the fish tightly in the foil, making sure the top layer of foil doesn’t touch the fish - otherwise, it may stick to the skin while baking and ruin the presentation.
Step 11
Place the tray in a preheated oven at 375°F (190°C). Bake for about 20 minutes (adjust timing based on your oven). Then open the foil and bake for another 10 minutes or until the surface becomes golden and crispy.
Step 12
Transfer the cooked fish to a serving plate, garnish with herbs and fresh vegetables, and enjoy!
