Prepare rice according to package directions.

While the rice cooks, heat olive oil in a large skillet over medium-high heat. Add the chopped onion and cook until softened, about 3-4 minutes. Stir in the minced garlic and cook for 1 more minute until fragrant.

Add the ground beef to the skillet. Cook, breaking it apart with a spoon, until fully browned. Drain any excess grease from the skillet.

Stir in the taco seasoning and water or beef broth. Bring to a simmer and let it cook for 2-3 minutes, stirring occasionally, until the sauce has thickened.

To assemble the taco rice bowls, divide the cooked rice among four bowls. Top with the seasoned ground beef, black beans, corn, and your desired toppings.
