- Add raw ground beef to the bottom of your slow cooker. 
- Sprinkle in chopped onion, garlic, taco seasoning, and salt/pepper. 
- Pour in tomato sauce and broth (and green chilies or salsa if using). 
- Stir gently to combine. Don’t worry if it’s not fully mixed yet. 
- Cover and cook on LOW for 5–6 hours or HIGH for 2.5–3 hours. 
- Once cooked, stir well and break up the beef with a spoon or spatula. 
- If too liquidy, cook uncovered for 15–20 minutes on HIGH to reduce moisture. 
- Taste, adjust seasoning if needed, and serve!
