Description

Light Mediterranean Seared Tuna Steaks over Braised Cavolo Nero with olives & capers. A flavorful, easy weeknight meal.


Ingredients

Scale
  • For the Tuna:
  • 2 (6-8 oz each) fresh tuna steaks, about 1-inch thick
  • 1 tbsp olive oil (for searing)
  • Salt and freshly ground black pepper, to taste
  • For the Braised Cavolo Nero:
  • 1 tbsp olive oil
  • 3 cloves garlic, minced
  • 1/4 tsp red pepper flakes (optional)
  • 1 large bunch (about 1 lb) cavolo nero, tough stems removed, chopped
  • 1/2 cup vegetable broth
  • 1/4 cup pitted Kalamata olives, halved
  • 1 tbsp capers, drained
  • 1/2 lemon, juiced
  • Finishing Touches:
  • 2 tbsp fresh parsley, chopped
  • Extra virgin olive oil, for drizzling
  • Lemon wedges, for serving

Instructions

  1. Prep the Cavolo Nero for Braising:: First things first, let’s get those greens ready. Wash your cavolo nero really well – sometimes those leaves hide a bit of grit, and nobody wants that! Trim off the tough bottom stems, then roughly chop the leaves into bite-sized pieces. I usually pile them up, then just go for it with a sharp knife. It doesn’t have to be perfect, just manageable for eating. This step always feels like I’m getting ready for something hearty and comforting, you know?
  2. Sauté the Aromatics:: Heat a glug of olive oil in a large, deep skillet or Dutch oven over medium heat. Toss in your minced garlic and a pinch of red pepper flakes. Sauté them gently for about a minute until fragrant – don’t let that garlic burn! I learned this the hard way once, and the whole dish tasted bitter. You want a lovely, golden aroma, not a harsh, acrid smell. This is where the magic really starts to happen, honestly.
  3. Braise the Cavolo Nero:: Add the chopped cavolo nero to the skillet. It’ll look like a mountain, but it’ll wilt down, promise! Pour in the vegetable broth, then stir in the pitted Kalamata olives and capers. Give it a good stir, cover the skillet, and let it braise for about 10-15 minutes, or until the cavolo nero is tender. I peek in occasionally, just to make sure it’s not drying out. The smell filling my kitchen at this point is just divine!
  4. Prepare the Tuna Steaks:: While the greens are braising, turn your attention to the tuna. Pat those beautiful steaks bone dry with paper towels. This is crucial for a good sear, trust me! Season both sides generously with salt and freshly ground black pepper. I always go a little heavy on the pepper, I just love that zing. Make sure they’re evenly coated; this is where the flavor really gets locked in.
  5. Sear the Tuna Steaks:: Heat another tablespoon of olive oil in a separate heavy-bottomed skillet (cast iron is my favorite for this!) over medium-high heat until it’s shimmering. Carefully place the tuna steaks in the hot pan. Sear for 1-2 minutes per side for rare to medium-rare, depending on their thickness and your preference. I like mine quite rare in the center, so I keep a close eye on the clock. Don’t overcrowd the pan, or you’ll lose that crisp sear!
  6. Assemble and Serve Your Seared Tuna Steaks over Braised Cavolo Nero:: Once the tuna is seared to your liking, remove it from the pan. Check the cavolo nero – it should be tender and flavorful. Give it a final squeeze of fresh lemon juice and a sprinkle of fresh parsley. Plate the braised cavolo nero first, then nestle a seared tuna steak right on top. A final drizzle of good extra virgin olive oil and maybe another lemon wedge on the side? Perfection! It always looks so vibrant and inviting.
