In a large Dutch oven, cook chopped bacon until crispy. Remove and set aside. Leave the rendered fat in the pot.
Add ground beef to the pot. Cook until browned, seasoning lightly with salt and pepper. Drain excess grease if needed.
Add onion, bell pepper, and garlic. Cook 4–5 minutes until softened.
Stir in smoked paprika, chili powder, cumin, cinnamon, and tomato paste. Cook for 1 minute until fragrant.
Mix in sweet potatoes, crushed tomatoes, diced tomatoes, maple syrup, bacon, and 1 cup beef broth.
Cover and simmer 25–30 minutes, stirring occasionally, until sweet potatoes are tender. Add more broth if needed to reach your desired consistency.
Stir in lime juice and adjust seasoning: more salt for depth, maple syrup for sweetness, or chili powder for extra heat.
Top with shredded cheddar, sour cream or Greek yogurt, fresh cilantro, or crushed tortilla chips.
