1Combine flour, salt, and pepper in a shallow dish; add beef pieces. Toss to coat each piece evenly. Reserve remaining flour mixture for later use.
2Heat oil in a large non-stick skillet; cook and stir coated beef, working in batches, until browned on all sides, about 10 minutes per batch. Transfer cooked beef to a slow cooker.
3Cook and stir onion in the same skillet used for beef until golden, about 5 minutes. Add beer and garlic; bring to a boil for 1 minute. Scrape browned bits of food from bottom of the pan with a wooden spoon. Pour onion mixture into the slow cooker.
4Mix beef broth, parsley, thyme, and bay leaves into beef mixture in slow cooker.
5Cook on Low until beef is almost tender, 2 1/2 to 3 hours. Sprinkle in the reserved flour mixture; stir well. Add potatoes and carrots.
6Cook on High until potatoes are tender, about 1 hour.
7Preheat oven to 400 degrees F (200 degrees C).
8Arrange puff pastry on baking sheets; pierce each piece several times with a fork.
9Bake in the preheated oven until golden and crispy, about 10 minutes. Ladle stew into individual dishes; top each with a pastry square.
