Start by bringing a large pot of salted water to a boil over high heat. Add your pasta and cook according to the package instructions, usually around 8-10 minutes until al dente. Stir occasionally to prevent sticking, then drain the pasta in a colander and set it aside, making sure to reserve a little pasta water in case you need to adjust the sauce's consistency later.

In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Once the oil is shimmering, add the chopped onion and sauté for about 2-3 minutes until it becomes translucent and fragrant.

Next, stir in 3 cloves of minced garlic, along with a teaspoon of Italian seasoning. Cook for about 1 minute, stirring continuously until the garlic is fragrant.

Add the ground beef to the skillet, using a wooden spoon to break it apart. Cook the meat for about 5 minutes, stirring occasionally, until it’s no longer pink and starts to brown.

Pour in your marinara sauce, stirring well to combine it with the browned beef mixture. Bring the sauce to a gentle simmer and let it cook for approximately 8 minutes, stirring occasionally.

Once the sauce has thickened slightly, season it with salt and pepper to taste. Gently fold the cooked pasta into the skillet, ensuring each piece is well-coated.

Finally, remove the skillet from heat and sprinkle in a generous amount of grated Parmesan cheese. Stir until the cheese melts into the pasta.
