Savory Mackerel with Herbed Potatoes and Caramelized Onions

Instructions for Making Savory Mackerel with Herbed Potatoes and Caramelized Onions

1. Prepare the Herbed Potatoes

• Preheat your oven to 400°F (200°C).
• Wash and peel the potatoes if desired (you can leave the skin on for extra texture and nutrients). Cut them into small cubes or wedges, depending on your preference.
• In a large bowl, toss the potatoes with olive oil, rosemary or thyme, garlic powder (if using), salt, and pepper. Make sure the potatoes are evenly coated with the herbs and oil.
• Spread the seasoned potatoes in a single layer on a baking sheet and bake for 25-30 minutes, or until golden and crispy on the outside and tender on the inside. Flip them halfway through cooking for even crispiness.

2. Caramelize the Onions

• While the potatoes are baking, heat butter or olive oil in a large skillet over medium-low heat.
• Add the thinly sliced onions to the skillet and stir to coat them in the fat. Sprinkle with a pinch of salt and sugar. The sugar will help the onions caramelize and become soft and golden brown.
• Cook the onions over low to medium heat, stirring occasionally, for about 15-20 minutes, or until they are deeply caramelized and soft. If the onions start to burn or stick to the pan, add a small splash of water or balsamic vinegar to deglaze the pan and add extra flavor.
• Once the onions are caramelized, remove them from the heat and set them aside.

3. Cook the Mackerel

• While the potatoes and onions are cooking, prepare the mackerel. Pat the mackerel fillets dry with paper towels and season both sides with salt, pepper, and smoked paprika (if using).
• Heat a tablespoon of olive oil in a skillet over medium-high heat.
• Once the oil is hot, carefully place the mackerel fillets in the skillet, skin-side down. Cook for 3-4 minutes on the first side until the skin is crispy and golden brown. Flip the fillets and cook for another 2-3 minutes, until the fish is cooked through and opaque.
• Remove the mackerel from the pan and set it aside.

4. Assemble the Dish

• Once everything is cooked, arrange the herbed potatoes on serving plates. Top with a generous spoonful of caramelized onions.
• Place the mackerel fillets on top of the potatoes and onions.
• Garnish with freshly chopped parsley for a pop of color and freshness.

Tips for the Best Savory Mackerel with Herbed Potatoes and Caramelized Onions

• Fresh Herbs: If possible, use fresh rosemary or thyme for the potatoes. Fresh herbs add a more vibrant flavor than dried and complement the mackerel beautifully.
• Crisp Skin: For the crispiest skin on the mackerel, make sure your skillet is hot before adding the fillets. Don’t overcrowd the pan, and avoid moving the fish around while it cooks to ensure the skin gets crispy.
• Customize the Potatoes: Feel free to swap out the rosemary or thyme for other herbs, such as oregano or sage, depending on your flavor preferences. You could also add a squeeze of lemon juice to the potatoes after they’re cooked for a bit of brightness.
• Sweeten the Onions: Adding a touch of sugar while caramelizing the onions helps them achieve a deep golden color and brings out their natural sweetness. You can also add a splash of white wine or balsamic vinegar for an extra layer of flavor.

Health Benefits of Mackerel and Potatoes

• Mackerel: This oily fish is an excellent source of protein and omega-3 fatty acids, which are known to support heart health, reduce inflammation, and improve brain function. Mackerel is also rich in vitamins D and B12.
• Potatoes: Potatoes are a great source of carbohydrates and are high in potassium, which supports muscle function and helps balance blood pressure. When baked with olive oil and herbs, they make for a satisfying and wholesome side.
• Onions: Caramelized onions add a rich sweetness to the dish, and onions themselves are packed with antioxidants and beneficial compounds like quercetin, which support immune health.
