Instructions

  1. Step 1: Pat dry 4 cod fillets and season both sides with 1/2 tsp sea salt and 1/4 tsp freshly ground black pepper. Heat 2 tbsp extra virgin olive oil in a large skillet over medium heat until shimmering.
  2. Step 2: Add cod fillets to skillet and cook undisturbed for 4-5 minutes until edges turn opaque and bottom is golden brown. Carefully flip and cook 3-4 minutes more until fish flakes easily with a fork. Remove cod from skillet and keep warm.
  3. Step 3: In the same skillet, add 1 tbsp extra virgin olive oil and 5 thinly sliced garlic cloves. Sauté over medium-low heat for 1-2 minutes until garlic is fragrant and just starting to turn golden.
  4. Step 4: Add 8 cups fresh spinach to the skillet, stirring frequently for 2-3 minutes until spinach is wilted and tender. Season with 1/2 tsp sea salt, 1/4 tsp black pepper, and 2 tbsp fresh lemon juice.
  5. Step 5: Serve cod fillets on a bed of garlic spinach, spooning any pan juices over the top for a light, Whole30-friendly seafood dish.

How do I store leftover Sautéed Cod with Garlic Spinach and Lemon?

How do I scale Sautéed Cod with Garlic Spinach and Lemon for a different number of people?
