Place the beef stew meat in the bottom of the slow cooker.
Add the potato chunks, butternut squash cubes, diced onion, and sliced carrots on top of the beef.
Pour the beef broth over the ingredients.
Sprinkle the minced garlic, dried thyme, salt, and black pepper across the top.
Stir gently to combine everything, then cover the slow cooker.
Cook on low for 8 hours until the beef is tender and the vegetables are soft.
