Instructions

  1. Step 1: Bring a large pot of salted water to a boil. Add 1 lb trimmed asparagus spears and blanch for 2-3 minutes until bright green and tender-crisp. Drain and immediately plunge into ice water to stop cooking. Set aside.
  2. Step 2: Pat dry 4 cod fillets and season both sides with 1 tsp sea salt and 1/2 tsp black pepper.
  3. Step 3: Heat 2 tbsp olive oil in a large non-stick skillet over medium heat. Add cod fillets and cook for 4-5 minutes per side until opaque and easily flakes with a fork. Remove and keep warm.
  4. Step 4: In the same skillet, add 1 tbsp olive oil, 2 minced garlic cloves, and sauté for 30 seconds until fragrant.
  5. Step 5: Stir in 3 tbsp fresh lemon juice and 2 tbsp rinsed capers. Cook for 1-2 minutes until the sauce slightly reduces.
  6. Step 6: Pour the lemon caper sauce over the cooked cod and sprinkle with 2 tbsp chopped fresh parsley.
  7. Step 7: Serve the cod with the blanched asparagus on the side, seasoning asparagus with remaining 1/2 tsp sea salt and 1/2 tsp black pepper if desired.

How do I store leftover Sautéed Cod with Lemon Caper Sauce and Blanched Asparagus?

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

How do I scale Sautéed Cod with Lemon Caper Sauce and Blanched Asparagus for a different number of people?
