01 - Preheat the oven to 375°F.
02 - Heat olive oil in a large skillet over medium heat. Add onion and cook until softened, about 3 minutes. Add garlic and cook for 1 minute more.
03 - Add ground beef and cook, breaking it up with a spoon, until browned and cooked through, about 6-8 minutes. Drain excess fat if needed.
04 - Stir in cumin, chili powder, smoked paprika, oregano, salt, and black pepper. Cook for 1 minute until fragrant.
