In a large pot, bring water to a boil. Once boiling, salt generously, and cook your rigatoni according to the package instructions, just 1 to 2 minutes before al dente. Drain your pasta, and set aside about 1/2 cup of pasta water.
In the meantime, make your sauce. In another medium skillet, heat a drizzle of sundried tomato oil over medium to medium-high heat. Then add your sausage in large chunks. Allow the sausage to slightly brown before using a spatula to mash the sausage into smaller pieces. I like to keep them into smaller chunks, and not into fine crumbles. Brown for 4 to 5 minutes, tossing occasionally until a nice golden crust forms on the sausage.
Add in your tomatoes, garlic, pepper, and salt. Toss to combine and allow the tomatoes to burst to create your sauce. Use the back of a spatula to squish and burst them, if needed, about 8 to 10 minutes.
Transfer about 1/4 cup of pasta water into the sauce, along with your pasta. Stir to combine and add in your parmesan cheese. Finish with a toss of basil leaves, adjusting with salt, pepper, and pasta water, as needed to taste.
Serve in bowls, topping with more parmesan, and basil leaves.

Notes
Brown your Sausage: Let your sausage sit untouched in medium chunks before stirring, and allow the time to brown the sausage before finishing your sauce.
Make it Creamy: Add a splash of heavy cream to your pasta sauce if you want a creamier finish.
Make it Vegetarian: Swap with a plant-based sausage meat alternative.
Storing: Store the pasta in an airtight container in the refrigerator for up to 2 to 3 days, and you can store the sausage tomato sauce in the freezer for up to 2 months.
Reheating: Reheat on the stovetop, low and slow, and add a splash of water if needed to add moisture. Stir to warm through and serve.
