Cook the Pasta: Bring a large pot of salted water to a rolling boil. Add uncooked pasta and cook until al dente, about 8-10 minutes. Drain and set aside.

Sauté the Onion: Heat olive oil in a skillet over medium-high heat. Add chopped onion and sauté for 4-5 minutes until soft and translucent.

Brown the Beef: Add ground beef to the skillet and cook for about 8 minutes until browned. Drain excess fat if necessary.

Add Flavors: Stir in minced garlic and cook for 1 minute. Add canned tomatoes, tomato paste, mustard, and seasoning. Simmer for 4-5 minutes.

Incorporate the Cream: Reduce heat to low, add heavy cream and stir. Simmer for another 3-5 minutes until thickened.

Final Seasoning and Combine: Season with salt and pepper. Fold drained pasta into the sauce until well-coated.

Serve and Garnish: Serve generous portions and sprinkle with grated Parmesan cheese if desired. Enjoy!
