Place the beef, sweet potatoes, onion, and garlic in the slow cooker.
Add the chipotle peppers, adobo sauce, beef broth, diced tomatoes, cumin, smoked paprika, salt, and pepper. Stir everything until evenly mixed.
Cover and cook on low for 7 to 8 hours or on high for 4 hours until the beef is very tender.
Ladle the stew into bowls and sprinkle with chopped cilantro before serving.
