Get the Dutch oven hot over medium heat or low steady flame.
Start cooking the beef by adding it to the Dutch oven. Stir occasionally as you work on browning the meat.
1 1/2 pounds ground beef
Season the ground meat with salt and pepper. Remove the meat from the Dutch oven and drain any excess grease from it without rinsing. Set the ground beef aside for now.
1/2 teaspoon kosher salt, 1/2 teaspoon pepper
Chop the onion and peppers into small pea-sized bits before putting them in the Dutch oven.
1 red bell pepper, 1 green bell pepper, 1/2 purple onion
Sauté the vegetables for eight to 10 minutes until they're tender and the onions have become translucent. Next, add the minced garlic and sauté for another two minutes.
2 tablespoons garlic
Put the ground beef back into the Dutch oven and mix it with the vegetables.
Add both the tomato sauce and crushed tomatoes to the pot and mix them in. Cover the Dutch oven and allow a slow boil to start to further cook the ground meat.
1 cup crushed tomatoes, 1/4 cup tomato sauce
Remove the lid and add all the remaining spices before mixing well. Place the cover back and let the chili simmer for 30 minutes over medium heat.
3 tablespoons chili powder, 1 tablespoon ground cumin, 2 teaspoons paprika, 1/2 teaspoon cayenne, 1 teaspoon oregano
Remove the lid and stir in the masa harina. Reduce the heat and then cover the Dutch oven. Let it cook on low heat for an hour or 300 F.
2 tablespoons masa harina

Serve the chili with your preferred toppings. Savor and enjoy.
