Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. In a small bowl, combine 4 tbsp softened unsalted butter, 1 tsp lemon zest, 2 tbsp lemon juice, 2 tbsp drained capers, and 1 minced garlic clove. Mix until well blended.
  2. Step 2: Place 4 cod fillets (5 oz each) in a greased baking dish. Season fillets evenly with 1/2 tsp salt and 1/4 tsp black pepper. Spread lemon-caper butter evenly over each fillet.
  3. Step 3: Bake cod for 12-15 minutes until fish is opaque and flakes easily with a fork.
  4. Step 4: Meanwhile, heat 2 tbsp olive oil in a medium saucepan over medium heat. Add 2 minced garlic cloves and sauté for 1 minute until fragrant.
  5. Step 5: Add 1 cup rinsed quinoa to the saucepan and toast for 2 minutes, stirring frequently. Pour in 2 cups low sodium vegetable broth and 1/2 tsp salt.
  6. Step 6: Bring quinoa to a boil, then reduce heat to low. Cover and simmer for 15 minutes until broth is absorbed and quinoa is fluffy.
  7. Step 7: Remove quinoa from heat and stir in 2 tbsp chopped fresh parsley and 1 tbsp chopped fresh dill. Season with additional black pepper to taste.
  8. Step 8: Serve baked cod fillets topped with the buttery lemon-caper sauce alongside garlic herb quinoa.
