Place the beef stew meat in the bottom of the slow cooker.
Add the cubed butternut squash, sliced carrots, chopped onion, cubed potatoes, and minced garlic on top of the meat.
Pour the beef broth over the ingredients.
Sprinkle the dried thyme, salt, and black pepper across the top.
Stir everything together gently to distribute the seasonings.
Cover and cook on low for 8 hours until the beef is tender and the vegetables are soft.
Stir once more before serving.
