Dutch Beef Croquettes, or 'Bitterballen', are a traditional Dutch snack that boast a crisp, golden exterior and a savory, succulent beef filling. Historically, these croquettes have delighted palates as both a street food and a beloved bar snack, bringing Dutch flavors to hearts and tables far and wide.
In a large pot, combine the beef, beef stock, and bay leaf. Simmer over low heat until the beef is tender and the stock has reduced by half, about 1 hour.
Remove the bay leaf. Shred the beef with two forks in the remaining stock.
In a separate pan, melt the butter over medium heat. Add the chopped onion, sautéing until translucent.
Stir in the flour to form a roux, cooking for 2-3 minutes until lightly golden.
Gradually whisk in the beef mixture to the roux, ensuring a smooth blend. Add the nutmeg, and season with salt and pepper to taste. Cook until the mixture thickens.
Let the mixture cool, then refrigerate until firm, approximately 2 hours.
Shape the chilled beef mixture into small logs.
Dredge each log in flour, dip in beaten egg, and coat with breadcrumbs.
Heat oil in a deep fryer to 180°C (350°F). Fry each croquette until golden brown and heated through, about 3-4 minutes.
Drain on paper towels, then serve hot.

Notes
For a lighter version, try baking the croquettes until golden. For an extra kick, add a teaspoon of mustard to the filling mixture.
