Brown the Beef: Heat the olive oil in a large skillet over medium-high heat. Add the beef cubes and cook until browned on all sides, about 5-7 minutes. Remove the beef from the skillet and set aside.
Sauté the Aromatics: In the same skillet, add the chopped onion and garlic. Sauté for 2-3 minutes, until fragrant and softened.
Cook the Rice: Add the rice to the skillet and stir to coat it in the oil and aromatics. Add the beef broth, Worcestershire sauce, dried thyme, salt, and pepper. Bring the mixture to a simmer.
Simmer and Stir: Reduce the heat to low, cover the skillet, and let the rice cook for about 15 minutes, until most of the liquid is absorbed and the rice is tender.
Add Cream and Beef: Stir in the heavy cream and the cooked beef. Cover and simmer for another 5 minutes, until everything is heated through and the sauce is creamy.
Serve: Taste and adjust seasoning with salt and pepper if needed. Garnish with fresh parsley, if desired. Serve warm and enjoy!
