Heat a large skillet over medium-high heat.
Add the ground beef to the hot skillet and break it up with a spatula.
Add the finely chopped onion and minced garlic to the beef, then sprinkle in salt, black pepper, smoked paprika, chili powder (if using), ground cumin, garlic powder, and onion powder.
Stir to combine all ingredients and continue cooking, breaking up any remaining large pieces, until the beef is no longer pink.
Reduce heat to medium and simmer for about 5 minutes, stirring occasionally, until most of the liquid has cooked off and the flavors are melded.
Remove from heat and serve the taco meat in tacos, bowls, or as desired.
