Preheat oven to 450 degrees F. While oven is preheating, spray the bottom of a large glass baking dish with avocado oil spray.

Place frozen tilapia filets in a single layer on the dish. Top each with a dollop of ghee – about ½ tablespoon each – and generously season with kosher salt and cracked black pepper.

Sprinkle rough-chopped garlic cloves all over the pan. Layer lemon slices right onto the tilapia.

Bake for 20 minutes. Serve with fresh, chopped dill or the herb of your choice.
