Wash and chop the broccoli into small florets. Dice the onion and mince the garlic.

In a large skillet over medium-high heat, brown the ground beef, breaking it apart as it cooks.

Add the chopped onion to the beef and cook until soft and translucent. Drain excess grease, then stir in the garlic for 1 minute. Remove the mixture to a plate.

In the same skillet over medium heat, add the olive oil, broccoli, and beef broth. Cover with a lid and steam for 4-5 minutes until tender.

Remove the lid, let the liquid evaporate, and return the beef mixture to the skillet. Stir in the salt, pepper, garlic powder, and red pepper flakes.

Reduce heat to low, sprinkle the grated cheddar cheese evenly over the top, and cover for 2-3 minutes until melted.

Serve immediately from the skillet.
