Ingredients
For the Pepper-Crusted Tuna:
- Tuna Steaks: 2 sushi-grade Ahi or Yellowfin tuna steaks (about 6 oz / 170g each, 1 to 1.5 inches thick).
- Peppercorn Crust: 1.5 tbsp coarsely cracked black peppercorns (or a mix of black, pink, and white peppercorns).
- Seasoning: 1 tsp coarse sea salt or kosher salt, and ½ tsp garlic powder.
- Oil: 1 tbsp olive oil or avocado oil (for searing).
For the Creamy Dijon Pan Sauce:
- Butter: 1 tbsp unsalted butter.
- Shallots: 1 small shallot (finely minced).
- Garlic: 2 cloves minced.
- Broth: ¼ cup low-sodium chicken or vegetable broth.
- Dijon Mustard: 1.5 tbsp Dijon mustard (or 1 tbsp Dijon + ½ tbsp Whole Grain mustard).
- Heavy Cream: ¼ cup heavy cream or double cream.
- Fresh Herbs: 1 tbsp chopped fresh chives or parsley for garnish.
Step-by-Step Instructions
- Prep and Crust the Tuna:
- Pat the tuna steaks completely dry on all sides using paper towels.
- Rub each steak lightly with a few drops of olive oil, then season generously with coarse salt and garlic powder.
- Spread the cracked peppercorns on a plate and press both sides of the tuna steaks firmly into the peppercorns to create an even crust.
- High-Heat Sear:
- Heat 1 tablespoon of oil in a heavy cast-iron skillet over high heat until smoking hot.
- Carefully lay the tuna steaks into the pan.
- Sear for 60 to 90 seconds per side for a classic rare center with a dark, sizzling pepper crust.
- Transfer the tuna steaks to a cutting board to rest while you prepare the sauce.
- Make the Creamy Dijon Sauce:
- Reduce the skillet heat to medium. Add 1 tablespoon of butter.
- Add minced shallots and garlic, sautéing for 1 to 2 minutes until soft and fragrant.
- Pour in the broth and Dijon mustard, scraping up any delicious browned bits from the bottom of the pan.
- Stir in the heavy cream and let the sauce simmer for 2 minutes until it thickens into a silky texture.
- Slice and Serve:
- Slice the pepper-crusted tuna steaks thinly across the grain using a sharp knife.
- Spoon the warm, creamy Dijon sauce onto the serving plate and arrange the seared tuna slices on top.
- Garnish with fresh chopped chives and serve immediately!
Chef’s Tips for Success
- Coarsely Cracked Peppercorns: Use freshly cracked peppercorns rather than fine ground black pepper. Coarsely cracked pepper gives the tuna a satisfying crunch and balanced spice without burning easily.
- High Heat is Essential: A smoking hot pan ensures a fast, beautifully charred crust while keeping the interior rich, pink, and rare.
- Serving Suggestions: Pair with garlic mashed potatoes, steamed asparagus, or a warm quinoa salad.
