Heat the olive oil in a large skillet over medium heat.

Add the ground beef to the skillet and cook, breaking it apart with a spatula, until browned and cooked through, about 6 to 8 minutes.

Stir in the diced onion and minced garlic and cook for 3 minutes, stirring occasionally, until the onion is translucent and fragrant.

Add the broccoli florets to the skillet and stir to combine with the beef mixture.

Season with salt, black pepper, garlic powder, onion powder, and red pepper flakes if using, then stir until the seasonings are evenly distributed.

Cover the skillet and cook for 5 to 7 minutes, stirring once or twice, until the broccoli is tender but still crisp.

Reduce the heat to low and pour in the heavy cream, stirring until it coats the beef and broccoli in a creamy sauce.

Add the Worcestershire sauce if using and stir to incorporate.

Sprinkle the shredded cheddar cheese evenly over the top, cover the skillet, and cook for 2 to 3 minutes, until the cheese is fully melted.

Remove from the heat and serve hot directly from the skillet.
