In a small bowl, mix the chili powder, cumin, paprika, garlic powder, salt, black pepper, and cayenne pepper. This blend gives the chili its signature bold flavor.
Step 2: Cook The Beef
Heat the cooking oil in a large pot over medium heat.
Add the ground chuck, breaking it up with a wooden spoon. Cook until browned and no longer pink. Drain any excess fat to avoid greasiness.
Step 3: Sauté The Onions
Push the beef to one side of the pot and add the chopped onions to the empty space.
Sauté for 3–4 minutes until the onions are soft and translucent, then mix them into the beef.
Step 4: Add The Liquid Ingredients
Stir in the tomato sauce and water, ensuring everything is well combined.
Step 5: Spice It Up
Sprinkle the spice blend evenly over the mixture and stir thoroughly.
Let the chili simmer on low heat for 45 minutes, stirring occasionally to prevent sticking.
Step 6: Thicken With Masa Harina
In a small bowl, mix masa harina with 2 tablespoons of water to form a paste.
Stir the paste into the chili and cook for an additional 5–10 minutes until the chili thickens to your liking.
