Set the puff pastry out at room temperature to thaw
Preheat the oven to 400 degrees
To a sautee pan, add the ground beef, garlic and onion and cook over medium heat until the ground beef is browned
Drain some of the fat, if desired
Season with salt and pepper
Add the flour and cook about 2 minutes
Increase the heat to medium high and deglaze with the red wine
Allow most of the wine to cook out (approximately 1-2 minutes), lower the heat to medium, then add the tomato paste, worcestershire sauce and beef broth and continue cooking until the mixture is combined and thickened (approximately 3-5 minutes)
Evenly divide the meat mixture between each of the 8 muffin tins
Roll the puff pastry out enough to press the seams together
Using a 2 1/2" biscuit cutter, cut 8 discs from the puff pastry sheet
Top each muffin tin with the puff pastry and pinch the edges together with a fork
Mix the egg with 1 tsp of water and brush the top of each pie with the egg wash
Cut a few slits in the top of the puff pastry to allow the steam to escape
Bake for 20 minutes
Serve with ketchup, if desired
