Clean the onions and slice them finely, then place them in a pan with three tablespoons of oil and let them "sweat" slowly, without frying. Season with salt and pepper. While the onions are cooking, wash and dry the slices of dogfish, dust them with a light coating of flour, and cook them in hot oil with garlic for 5 minutes on each side. Pour in a glass of white wine and let it evaporate completely over low heat. Strain the onions and pour the puree into a saucepan. Add a teaspoon of flour and a tablespoon of butter. Stir over the heat and dilute with half a glass of white wine. Cook the sauce, stirring constantly, for five minutes. Then immerse the fish slices in it. Let everything infuse for another five minutes and serve.
One of the tastiest variations of dogfish in onion sauce is certainly the pairing with baked potatoes. In this preparation, the potatoes are diced and cooked in the oven with a drizzle of oil, rosemary, and a pinch of salt. During cooking, the potatoes absorb the aromas and flavors of the onion sauce, creating a dish that is a true triumph of flavors. The sweetness of the onions perfectly complements the soft texture of the potatoes, making each bite truly enveloping. This variation is ideal for a family lunch or a dinner among friends, as it offers an excellent combination of ingredients that satisfies any palate.

The onions, slowly sautéed, will maintain their intense flavor, while the dogfish will be equally tasty and tender. This preparation is perfect for those who want to maintain a healthy diet without sacrificing flavor. Additionally, by eliminating butter, the total calories of the dish are reduced, making it suitable even for those on a low-calorie diet.

Dogfish is a fish rich in protein and low in fat, ideal for a balanced diet. It is an important source of omega-3, essential fatty acids that promote cardiovascular health and reduce inflammation. Onions, on the other hand, are rich in antioxidants and vitamins, helping to strengthen the immune system. A serving of dogfish in onion sauce (about 150 grams) provides approximately 250 calories, making it a nutritious and filling dish. Thanks to the combination of these ingredients, this dish is not only tasty but also offers various health benefits, making it suitable for those who wish to take care of their well-being.
Freezing dogfish in onion sauce is possible, but it is important to follow some guidelines to preserve its quality. Before freezing, make sure that the fish and sauce are completely cooled. It is advisable to portion the dogfish into food bags, removing as much air as possible to avoid freezer burn. When you decide to consume it, simply thaw it slowly in the refrigerator overnight and then gently reheat it in a pan or in the microwave. Keep in mind that the texture of the onions may change slightly after freezing, but the flavor will still remain delicious. This solution is useful for those who love to prepare meals in advance and want to always have a tasty and nutritious dish on hand.
