Ham and Spinach Dip

Preheat oven to 425 degrees. Melt butter in a medium saucepan over medium heat. Add onion and cook, stirring, until softened, about 3 minutes. Add flour and cook, stirring, 1 minute more. Add milk and whisk until mixture has thickened, about 4 minutes. Remove from heat; stir in paprika, ham, 3/4 cup cheese, and spinach. Season with salt and pepper.
Transfer mixture to a 1-quart baking dish. Top with remaining 1/2 cup cheese and sprinkle lightly with more paprika. Bake 10 minutes. Adjust oven to broil; broil until golden brown, about 3 minutes. Let cool 5 minutes and serve.
