Instructions

  1. Step 1: Pat dry 4 Istrian trout fillets (6 oz each) and season both sides with sea salt and freshly ground black pepper to taste.
  2. Step 2: Heat 2 tbsp extra virgin olive oil in a large non-stick skillet over medium-high heat until shimmering, about 2 minutes.
  3. Step 3: Place trout fillets skin side down and cook for 4-5 minutes without moving until skin is crisp and golden; flip and cook the other side for 2-3 minutes until fish is opaque and flakes easily.
  4. Step 4: While trout cooks, combine 1/2 cup chopped black olives, 2 tbsp rinsed capers, 2 minced garlic cloves, 1 tbsp finely chopped rosemary, 1 tbsp finely chopped thyme, 1 tsp lemon zest, 2 tbsp fresh lemon juice, and 1 tbsp extra virgin olive oil in a bowl; mix well to create tapenade.
  5. Step 5: Remove trout from skillet, plate, and spoon the olive and herb tapenade generously over each fillet while still warm to release aroma and flavors.

How long does Pan-Seared Istrian Trout with Herb and Olive Tapenade take to make?

How do I store leftover Pan-Seared Istrian Trout with Herb and Olive Tapenade?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish).

How do I scale Pan-Seared Istrian Trout with Herb and Olive Tapenade for a different number of people?
