How to Make Creamy Mustard Baked Mackerel on a Bed of Onions
Step 1. Start by thawing the mackerel if it’s frozen. Make sure to gather all the necessary ingredients.
Step 2. In a large bowl, combine the sour cream, salt, mixed pepper, both types of mustard, and soy sauce. Mix them thoroughly using a whisk.
Step 3. Peel and thinly slice the red onions into half-rings. Add the sliced onions to the marinade and mix well.
Step 4. Remove the heads, tails, and fins from the mackerel. Cut the fish along the belly to remove all the innards, blood, and dark membranes, which can cause bitterness. Cut the mackerel into 1.5-2 cm thick slices, ensuring you remove any bones, which are usually easy to take out.
Step 5. Place the mackerel slices in the marinade with the onions. Ensure they are well coated with the creamy mustard mixture. Leave them to marinate for about 30 minutes.
Step 6. After 15 minutes of marination, preheat your oven to 180°C (356°F).
Step 7. In a baking dish, make a small bascket with parchment. Place there the marinated onions as a base.
Step 8. Put the marinated mackerel slices on top of the onions. Bake the fish and onions in the preheated oven for 30 minutes.
Step 9. Serve: Once baked, your creamy mustard mackerel with onions is ready to be enjoyed. It’s aromatic and delicious, and it can be served hot or cold.
