Heat olive oil in a large, deep skillet over medium heat until shimmering. Add the chopped onion and minced garlic, cooking until they become soft and fragrant, about 3-4 minutes.
02 -
Add the ground beef to the skillet, breaking it apart with a wooden spoon as it cooks. Continue cooking until the meat is fully browned with no pink remaining, about 5-7 minutes. If there's excess fat, carefully drain it off.

Pour in the beef broth, heavy cream, and diced tomatoes with their juice. Stir everything together until well combined, scraping up any browned bits from the bottom of the pan.

Bring the mixture to a gentle boil, then reduce to a simmer. Add your pasta directly to the skillet and stir to incorporate. Let it cook in the sauce until tender but still slightly firm (al dente), about 10-12 minutes. Stir occasionally to prevent sticking.

Once the pasta is cooked, remove the skillet from heat and stir in the grated Parmesan cheese until melted and creamy. Season with salt and pepper to taste. Serve hot in bowls with extra Parmesan on top if desired.
