Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 25 minutes
• Total Time: 40 minutes
• Servings: 4
• Dietary Type: Dairy-Free

Ingredients

• 2 tablespoons olive oil
• 1 large onion, thinly sliced
• 1/4 cup celery, chopped
• 1/4 cup fresh Italian parsley, finely chopped
• 1 garlic clove, chopped
• 1 1/2 lbs ripe plum tomatoes, peeled, coarsely chopped
• 1 bay leaf
• 1 cup fresh basil, torn into bite-size pieces
• 4 (6 ounce) tuna steaks (about 1 inch thick)
• Fresh basil sprigs, for garnish
• Salt and pepper to taste

Equipment Needed

• Heavy large skillet
• Another heavy large skillet
• Platter

Instructions

1. Heat 1 tablespoon of olive oil in a heavy large skillet over medium heat.
2. Add the thinly sliced onion, chopped celery, finely chopped Italian parsley, and chopped garlic. Sauté until the onion is tender but not brown, approximately 10 minutes. Ensure you stir frequently to prevent burning.
3. Add the coarsely chopped ripe plum tomatoes and the bay leaf to the skillet.
4. Cover the skillet and cook until the sauce thickens, stirring occasionally, for about 15 minutes. This allows the flavors to meld and the tomatoes to break down, creating a rich sauce. At this stage, the sauce can be prepared a day in advance. Simply cover and refrigerate. Rewarm gently before continuing with the recipe.
5. Remove and discard the bay leaf from the sauce. It has imparted its flavor and is no longer needed.
6. Mix in the torn fresh basil into the tomato sauce. The heat will slightly wilt the basil, releasing its aromatic oils and intensifying the flavor.
7. Season the sauce to taste with salt and pepper. Adjust the seasoning according to your preference. Remember that the tuna will also be seasoned.
8. Sprinkle the tuna steaks with salt and pepper on both sides. Be generous with the seasoning to enhance the tuna’s natural flavor.
9. Heat the remaining 1 tablespoon of olive oil in another heavy large skillet over medium-high heat. The skillet should be hot enough to sear the tuna properly.
10. Add the seasoned tuna steaks to the hot skillet and cook until golden and just opaque in the center, about 3 minutes per side. For a perfect sear, avoid moving the tuna around in the skillet until it has formed a crust on the bottom. The internal temperature should reach approximately 145°F (63°C) for medium doneness.
11. Transfer the cooked tuna steaks to a platter.
12. Spoon the prepared tomato-basil sauce generously over the tuna steaks.
13. Garnish with fresh basil sprigs before serving to add a touch of freshness and visual appeal.

Expert Tips & Tricks

• For a richer flavor, use high-quality olive oil. It makes a significant difference in the overall taste of the dish.
• If you don’t have fresh plum tomatoes, you can substitute a can of good-quality crushed tomatoes. Just be sure to adjust the cooking time accordingly.
• To prevent the tuna from overcooking, ensure the skillet is hot before adding the steaks. This will create a nice sear and help keep the tuna moist.
• If you prefer your tuna more well-done, simply cook it for a minute or two longer on each side.
• Don’t overcrowd the pan when searing the tuna. If your pan is too small, cook the tuna in batches to ensure even browning.
• Adding a pinch of red pepper flakes to the tomato sauce will give it a pleasant kick.
• For a more intense basil flavor, add half of the basil during the last 5 minutes of the sauce cooking time, and the other half just before serving.
• If your sauce becomes too thick, add a splash of pasta water or vegetable broth to thin it out.
• A squeeze of lemon juice at the end brightens the flavors of the dish.

Serving & Storage Suggestions

Tonno Alla Livornese is best served immediately after cooking. The warm tuna and the vibrant sauce create a delightful combination. You can serve it with crusty bread for soaking up the delicious sauce, alongside a simple green salad, or with a side of roasted vegetables like asparagus or zucchini.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm the tuna and sauce in a skillet over low heat or in the microwave. Be careful not to overcook the tuna during reheating, as it can become dry. The sauce can also be frozen for up to 2 months. Thaw it in the refrigerator overnight before reheating.

Q: Can I use dried basil instead of fresh basil?
