Bring a large pot of water to a boil. Once the water is boiling, generously salt the water.
Boil the rigatoni until al dente. Before draining the pasta, reserve 1 cup of the pasta water.
½ lb Rigatoni pasta
Preheat the oven to 375°F.
In a large pot, heat ½ a tablespoon of olive oil. Brown the Italian sausage, taken out of the casing. Break the sausage apart into small crumbles. Once the sausage is mostly browned, add the onion and garlic. Sauté until fragrant and the onions are translucent.

Add the tomato paste and dried spices to the sausage, onion and garlic mixture. Combine everything well, and cook the tomato paste through for 2-3 minutes to get rid of the raw tomato flavor. Add the heavy cream once the tomato paste is cooked through, and combine well. Taste for salt, and adjust to your taste.
¼ cup Tomato paste, ½ cup Heavy cream, 1 ½ teaspoon Dried oregano, 1 teaspoon Red chilli flakes, Sea salt
Add the cooked rigatoni, and a generous splash of the pasta water to the pot. Toss well. Add more pasta water if you feel that the sauce is too thick.
1 cup Pasta water
Transfer the pasta to a 10.5 x 7.5" baking dish, and top with torn bocconcini cheese. Bake the pasta for 10-15 minutes, and then broil for 5 minutes on HI, until the cheese is fully melted and lightly browned.
