Bring a large pot of salted water to a boil and cook the rigatoni according to package directions until al dente. Drain the pasta and set it aside.
While the pasta cooks, place the chopped bacon in a large skillet over medium heat. Cook until the bacon turns crispy, then remove it with a slotted spoon and leave about 2 tablespoons of bacon fat in the pan.
Add the minced garlic to the skillet and cook for 30 seconds until fragrant. Stir in the frozen corn and cook for 2 minutes.
Pour the heavy cream into the skillet. Add the salt, black pepper, and Parmesan cheese. Stir until the cheese melts and the sauce thickens slightly, about 2 minutes.
Add the drained rigatoni and cooked bacon to the skillet. Toss everything together until the pasta is evenly coated. Sprinkle with fresh parsley before serving.
