Preheat oven to 400-degrees.
Prepare cream sauce (see instructions below) and set aside, keeping warm.
Spray a 9x13 baking dish with cooking spray and place cod fillets in the dish. Sprinkle with salt.
Combine melted butter and garlic and brush over fillets, reserving any leftover butter mixture.
Sprinkle seasoned breadcrumbs over fillets and pour remaining butter mixture over the top.
Pour cream sauce in the spaces between the cod fillets so it fills up the baking dish and just the tops of the fillets are visible.
Place in the preheated oven and bake for 25-30 minutes or until the cream sauce starts bubbling.
When the sauce starts bubbling up, set oven to "broil" and broil for about 3-5 minutes or until the fillets start to turn golden brown.
Keep a CLOSE eye on it to make sure it doesn't start to burn.
Remove from oven and serve with potatoes, rice, or vegetables.
