Instructions
Prepare + Cook Cod:
Mix together all of the blackening seasoning ingredients in a small bowl.Brush an oven-safe pan with half the oil (1 tablespoon). Alternatively, use a sheet pan.Add the cod to the pan, and generously season the top of the fish with the blackening spices.Extra Seasoning Note: You will probably use about half the blackening seasoning. Reserve the remaining seasoning for another use.
Drizzle the remaining 1 tablespoon oil on the fish, and use your fingers to rub the oil into the seasoning.
Move an oven rack to about 4" away from the broiler. Preheat broiler to high.Slide the pan into the oven.Cook cod for 4 minutes per ½" thickness, or until the fish is tender and easily flakes apart with a fork.Do not flip the fish halfway through cooking.
While the fish broils, make the avocado sauce. Add the yogurt, avocado, and lemon juice to a blender or food processor and purée until smooth. Add more lemon juice to thin out the sauce if desired. Optionally, you could use a fork to mash the avocado into the yogurt and lemon juice. Your sauce will likely be less smooth.Serve the cod right away along with the avocado sauce.
