- Cook the tortellini according to packet instructions. Drain into a colander and cover to stay warm. Set aside.
- Meanwhile, heat the oil in a large frying pan over a medium high heat. Add the onion and bacon, and fry for 5 minutes or until the bacon begins to brown and the onion softens. Add the mushrooms and continue to fry for 3-5 minutes or until the mushrooms start to turn golden.
- Reduce the heat to low and stir in the cream, chopped parsley, and ¾ of the Parmesan. Simmer for a couple of minutes until the cheese has just melted. Season with salt and pepper. Add the cooked tortellini to the pan and stir well to coat the pasta.
- Sprinkle over the remaining Parmesan and serve
