Preheat the oven at 400°F. If you haven't cooked the Fusilli yet, do so using our instructions in the how-to-make section of this article. Follow the next steps to prepare the meat sauce while it's cooking.
Heat 1 tbsp olive oil in a skillet over medium heat. Add a few pieces of minced garlic and when they sizzle, add the rest (1 tbsp) and sauté for 30 seconds or until fragrant. Add 2 oz chopped onions and stir to cook for another 2 minutes.
Add 1 tbsp tomato paste to the skillet and stir so it cooks evenly in the oil and coats the aromatics. Tip 4 oz chopped tomatoes in and cook for 1 minute.
Add 12 oz ground beef to the skillet along with the herbs and seasonings: 2 tsp brown gravy mix, 1 tsp Italian seasoning, 1 tsp paprika, 1/2 tsp salt, and 1/2 tsp ground black pepper. Stir to cook for 2 minutes, breaking up the meat into little pieces while it cooks.
Pour 1/2 cup chicken broth in and simmer the sauce over low heat for another 5 minutes.
Turn the heat off and stir in 12 oz al-dente Fusilli. Pour everything into a baking dish.
Sprinkle 2 oz shredded cheddar and 1 oz shredded mozzarella on top, and slide it all into your preheated oven to bake for 7 minutes.
Sprinkle 2 tbsp finely chopped fresh parsley on top and serve.
