Seared Tuna with Caramelized Onions

Category: Main Course
Servings: 4

Ingredients

Ingredient Quantity
Tuna (steaks) 880g
White onions 720g
Tomato passata (sauce) 35g
White wine 300g
Water 200g
Sugar 1 teaspoon
Fresh parsley 1 bunch
Extra virgin olive oil to taste
Fine salt to taste
Black pepper to taste

Instructions

  1. Prepare the Onions
    Start by peeling the white onions. Slice them in half, then cut them into thin slices.

  2. Cook the Onions
    Heat a generous drizzle of extra virgin olive oil in a saucepan over medium heat. Add the sliced onions to the pan and sprinkle in the sugar to help caramelize them. Stir occasionally and cook until the onions soften and turn a golden brown. This may take around 20 minutes.

  3. Sear the Tuna
    In a separate pan, heat a bit more olive oil over medium-high heat. Place the tuna steaks in the pan and sear them for about 2-3 minutes on each side, depending on your preferred level of doneness. Once seared, remove the tuna steaks from the pan and set them aside.

  4. Combine the Ingredients
    After the onions are caramelized, take a larger pan and heat a little more olive oil over medium-high heat. Add the caramelized onions to the pan. Stir them gently, then pour in the white wine to deglaze the pan, allowing the alcohol to cook off. This should take a few minutes.

  5. Add Tomato Sauce and Simmer
    Once the alcohol has evaporated, add the tomato passata (sauce) into the pan. Season with salt and pepper to taste. Stir everything well.

  6. Finish the Sauce
    Pour in the water and bring everything to a gentle simmer, allowing the flavors to meld together for another 5 minutes.

  7. Serve
    Place the seared tuna steaks on a serving dish, then spoon the caramelized onion and tomato sauce over the top. Garnish with freshly chopped parsley and serve immediately, either hot or at room temperature for a delicious meal.
