Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine the lump crab meat, shredded cheddar cheese, mayonnaise, green onions, garlic powder, Worcestershire sauce, Old Bay seasoning, salt, and pepper. Mix until well combined.
Gently fold in the crushed Ritz crackers until evenly distributed throughout the mixture.
Spoon the mixture into a greased baking dish or onto a lined baking sheet, forming small mounds or patties.
Bake in the preheated oven for 15-20 minutes, or until golden brown and bubbly.
Remove from the oven and let cool slightly before garnishing with chopped parsley. Serve warm.
