Sauté the Aromatics: In a large pot or Dutch oven, heat the oil over medium-high heat. Add the ground beef and cook, breaking it apart, until well-browned. For the best flavor, let the beef develop a nice sear. If there is excess grease, drain it off.
 - 
Build the Flavor Base: Add the chopped bell pepper, onion, celery, and jalapeño (if using) to the pot. Sauté for 5-7 minutes, until the vegetables have softened. Stir in the minced garlic and cook for another minute until fragrant.
 - 
Combine Everything: Pour in the tomato sauce and diced tomatoes. Add the pinto and kidney beans with their canning liquid—this helps create the chili’s signature thick texture. Stir everything to combine.
 - 
Season and Simmer: Add the chili powder, cumin, oregano, salt, and pepper. Stir well to incorporate the spices. Bring the chili to a boil, then immediately reduce the heat to low to maintain a gentle simmer.
 - 
Slow Cook to Perfection: Cover the pot, leaving the lid slightly ajar. Let the chili simmer for at least 2 hours, stirring occasionally. This slow cooking time is essential for the flavors to fully develop. If the chili becomes too thick, add a splash of water or beef broth. If it’s too thin, simmer with the lid off for the last 30 minutes.
 - 
Serve and Enjoy: Taste and adjust seasoning if needed. Let the chili rest for 5 minutes before serving. Ladle into bowls and top with your favorite garnishes like shredded cheese, sour cream, or diced onions.
 
Chef’s Tips for the Best Chili
- 
Brown for Flavor: Don’t rush browning the beef. Those caramelized bits at the bottom of the pot are packed with flavor.
 - 
Make-Ahead Magic: Chili almost always tastes better the next day. Make it ahead and reheat it for an even more robust and rich flavor.
 - 
Customize It:
- 
For more heat: Add a pinch of cayenne pepper or a dash of your favorite hot sauce.
 - 
For a smoky twist: Stir in 1 teaspoon of smoked paprika with the other spices.
 - 
For an herby note: Add a bay leaf during simmering and remove it before serving.
