In a frying pan, sauté the onion and chopped garlic in a drizzle of olive oil. If you are using garlic powder, add it after the shrimp.
Add the mushrooms and cook for a few minutes, then add the peeled shrimp.
Season with salt and pepper, and let simmer until all the cooking juices have evaporated.
If you are using squid rings, first cook them in a little water for 15 minutes, drain, then add them to the pan along with the mushrooms and shrimp.
Turn off the heat and set aside until ready to serve.
Just before serving, pour the heavy cream over the shrimp and mushrooms, let it thicken for a few minutes over low heat, then add the cheese. Stir until it’s fully melted, then turn off the heat. The sauce should be nicely thick and coat the ingredients well.
Carefully take the salmon out of the oven, remove the aluminum foil, then place it with the parchment paper directly onto the serving dish. Gently peel away the parchment paper by sliding it out from under the fish.
Remove the skin from the top of the salmon using a knife or a flat spatula, then pour the creamy seafood sauce over the top.
Arrange the sautéed vegetables around the salmon for a beautiful presentation. You can also sprinkle some chopped dill or chives on top to add a touch of freshness and color.
Garnish with a few lemon slices and serve immediately!
