Cook the Pasta: Fill a large pot with water and bring it to a boil. Add salt and penne pasta, cooking until al dente (10-12 minutes). Drain and set aside.

Sauté the Garlic: In a large skillet, heat olive oil over medium-high heat. Add minced garlic and sauté until fragrant (about 1 minute).

Brown the Ground Beef: Add ground beef to the skillet, breaking it up as it cooks for 6-8 minutes until browned. Drain excess fat if necessary.

Season the Meat: Stir in salt, black pepper, and Italian seasoning, along with optional crushed red pepper flakes. Cook for 1-2 minutes to blend flavors.

Create the Creamy Sauce: Reduce heat to medium, add beef broth and heavy cream. Simmer for 3-4 minutes to thicken.

Combine Pasta and Sauce: Stir in the drained pasta until well-coated. Heat for an additional 1-2 minutes.

Stir in the Cheese: Gradually mix in grated Parmesan cheese until melted and sauce thickens.

Melt the Mozzarella: Sprinkle shredded mozzarella over the pasta and cover to let it melt (3-5 minutes).

Garnish and Serve: Top with fresh parsley before serving. Enjoy your comforting meal!
