Instructions

Step 1: Preheat oven to 400°F. Place 4 cod fillets in a baking dish and drizzle with 1 tbsp olive oil, 2 tbsp lemon juice, 1 tbsp chopped fresh rosemary, 1 tsp salt, and 1/2 tsp black pepper. Let marinate for 10 minutes.
Step 2: Bake the cod for 12-15 minutes until the fish flakes easily with a fork and is opaque throughout.
Step 3: While the cod bakes, heat 2 tbsp olive oil in a large skillet over medium heat. Add 3 minced garlic cloves and sauté for 30 seconds until fragrant.
Step 4: Add 1 lb trimmed green beans to the skillet, season with a pinch of salt, and cook, stirring frequently, for 6-8 minutes until tender-crisp and bright green.
Step 5: Serve the baked cod fillets hot with garlic green beans on the side, garnished with extra lemon wedges if desired.
