Step-by-step instructions.
Preheat and brown
Preheat the smoker to 250°F. On the stovetop, brown the beef in an uncovered Dutch oven over medium-high heat for 8–10 minutes, breaking it up. Cook ground beef to 160°F and drain excess grease, leaving about a tablespoon.
Build the base
Add onion and cook 5–7 minutes until softened. Add garlic, tomato paste, chili powder, cumin, paprika, and oregano. Stir for 1 minute so the spices smell fragrant without scorching.
Smoke the chili
Stir in tomatoes, broth, salt, and pepper. Bring to a simmer on the stovetop. Transfer the uncovered Dutch oven to the smoker and cook 2 hours, stirring every 30 minutes. Add a little broth if it gets too thick.
Adjust and serve
Taste and simmer up to 30 minutes longer for a thicker chili. Stir in vinegar and adjust salt. Serve hot. For extended serving, hold at 140°F or above. On the stovetop, the same chili can simmer partly covered on low for 1½–2 hours; stir regularly.
Ground beef must reach 160°F; keep finished chili at 140°F or above during extended hot holding. Check the thickest part with a thermometer, away from bone or the hot pan.
