Fill a large pot with water and bring it to a boil. Add salt and pasta. Cook until slightly firm. Save half a cup of pasta water before draining the pasta completely.

Heat olive oil in a large skillet over medium heat. Add chopped onions and cook slowly for about five minutes. Stir often until soft, golden, and sweet-smelling.

Add minced garlic to the onions. Stir gently for one minute. The garlic should smell fragrant but not burnt. This step builds rich flavor for the creamy beef pasta sauce.

Add ground beef to the skillet. Break it apart with a wooden spoon while cooking. Cook until brown and fully done. Drain extra grease if the beef looks too oily.

Sprinkle salt, pepper, paprika, and Italian seasoning over the beef mixture. Stir well so every bite gets coated with flavor. The warm spices make this dish extra cozy.

Add tomato paste to the pan and mix well. Cook for two minutes. This helps deepen the flavor and gives the creamy sauce a richer taste and color.

Slowly pour beef broth into the skillet. Stir gently while scraping the bottom of the pan. Let the mixture simmer for five minutes to blend all flavors together.

Reduce the heat to low. Pour in heavy cream and add parmesan cheese. Stir slowly until the cheese melts fully and the sauce becomes creamy and smooth.

Add cooked pasta into the creamy beef sauce. Toss gently until every piece is coated. Add a little reserved pasta water if the sauce feels too thick.

Stir in butter and fresh parsley before serving. Spoon the creamy beef pasta into bowls and serve warm. The creamy texture tastes perfect on chilly evenings.
