Ingredients

• Cod Fillets: 4 (6 oz each), patted dry
• Asparagus: 2 bunches (24 oz total), tough ends trimmed

   • Stir in lemon juice and scrape up any browned bits.
4. Combine and Finish:
   • Return cod to skillet, nestling into asparagus. Spoon sauce over cod.
   • Sprinkle with remaining lemon zest and parsley.
   • Garnish with lemon slices and extra parsley. Serve immediately.
