1.   Preheat your oven to 400 F or about 200 C. Lightly grease a casserole pan with 1 tbsp of the butter

2.   Pat dry the cod fillets. Salt and pepper both sides of the fillets. Place into the casserole dish

3.   Make the seasoned butter: into a small bowl add the room temperature butter and combine with the grated parmesan cheese, lemon zest, garlic powder, fresh or dried basil, Dijon mustard and the lemon juice. Mash with a fork until well combined

4.   Spoon the seasoned butter on top of the fish fillets. Use the back of a spoon to flatten the seasoned butter over surface of the fish. Cover with cling wrap and refrigerate until about 30 minutes before baking. Remove from fridge and let fish get to room temperature before baking

5.   Place into the middle position of the preheated oven and bake for about 15 – 20 minutes. Timing will vary due to thickness of the fish fillets. Adjust accordingly. Fish is done when it flakes easily if you insert a fork. When done, remove from casserole dish. Reserve the drippings

OPTIONAL Green French Beans

6.   In a separate pot, filled about half way with water, bring water to a brisk boil and then add the fresh or frozen French green beans. Cook until the green beans are al dente (cooked, but still crispy)

7.   Drain the water and immediately cover the green beans with very cold water/ice water. Let soak for 2-3 minutes until completely cooled, and drain the water

8.   Season with salt, and toss. When serving, use some of the fish sauce to pour over the green beans or just sprinkle some almond flour or slivered almonds on top
