Step 1

Heat oil in a large Dutch oven over medium-high. Add onion, poblano, and garlic, and cook, stirring often, until tender, about 5 minutes. Add ground chuck, and cook, stirring occasionally, until beef crumbles and is no longer pink, 8 to 10 minutes. Drain beef mixture well, and return to Dutch oven over medium-high.

Step 2

Add tomato paste, ancho chile powder, cumin, salt, pepper, thyme, and oregano, and cook, stirring often, 2 minutes.

Step 3

Increase heat to high. Stir in beans, tomatoes, chicken broth, and beer, and bring to a boil. Reduce heat to medium-low, and simmer, stirring occasionally, until heated through, about 30 minutes. Serve chili with desired toppings.
