Place the beef stew meat in the slow cooker. Add the minced chipotle peppers, adobo sauce, onion, garlic, cumin, smoked paprika, salt, and black pepper.
Pour the beef broth over the meat and spices. Stir once to combine everything evenly.
Add the potatoes and carrots on top of the broth mixture. Cover and cook on low for 7 hours.
After 7 hours, stir in the sliced red bell peppers. Cover again and cook on low for 1 more hour until the peppers are tender.
Taste and adjust salt if needed. Ladle into bowls and sprinkle with chopped cilantro before serving.
