Ingredients
  

  • 1 to 1.5 pounds cod fillets, skinless (cut into 4 portions)
  • 1 bunch asparagus, woody ends trimmed
  • 3 tablespoons unsalted butter
  • 2 tablespoons olive oil
  • 1 large lemon (zest and juice)
  • 2 garlic cloves, minced
  • 1/4 cup dry white wine or low-sodium chicken broth (optional but recommended)
  • 2 tablespoons fresh parsley, chopped (or 1 tablespoon chives)
  • Salt and black pepper, to taste
  • 1/4 teaspoon red pepper flakes (optional, for a little heat)
  • Lemon wedges, for serving

Method
 

  1. Prep the cod: Pat the fillets very dry with paper towels. Season both sides with salt and pepper. Zest the lemon and set the zest aside for later.
  2. Heat the pan: Place a large skillet over medium-high heat. Add 1 tablespoon olive oil and 1 tablespoon butter. When the butter foams and the pan is hot, it’s ready.
  3. Sear the asparagus: Add the asparagus in a single layer with a pinch of salt and pepper. Cook, turning occasionally, until bright green and just tender with some caramelized spots, 4–6 minutes depending on thickness. Transfer to a plate.
  4. Sear the cod: Add another tablespoon of olive oil to the pan. Place the cod in the skillet and let it sear undisturbed until it releases easily and is golden on the first side, about 3–4 minutes. Carefully flip and cook another 2–4 minutes, depending on thickness, until the fish flakes easily. Transfer the cod to the plate with the asparagus and tent loosely with foil.
  5. Build the sauce: Turn the heat to medium-low. Add the remaining 2 tablespoons butter to the pan. Stir in the garlic and cook 30 seconds until fragrant, not browned.
  6. Deglaze: Pour in the white wine or broth and scrape up any browned bits. Let it bubble for 1–2 minutes to reduce slightly. Stir in the lemon juice, lemon zest, red pepper flakes if using, and a pinch of salt and pepper. Taste and adjust—more lemon for brightness, more butter for richness, a pinch of salt if needed.
  7. Finish and serve: Return the asparagus to the pan and toss in the sauce. Nestle the cod on top and spoon sauce over the fish. Sprinkle with fresh parsley. Serve immediately with extra lemon wedges.
