Bring a large pot of salted water to a boil and cook tortellini according to package directions. Drain and set aside.
In a large skillet over medium heat, cook chopped bacon until crispy. Remove bacon and set aside, leaving drippings in the pan.
Add minced garlic to the skillet and sauté for about 30 seconds until fragrant.
Lower heat and pour in heavy cream, stirring to combine.
In a small bowl, whisk egg yolks with Parmesan. Slowly add a few spoonfuls of the hot cream mixture to temper the yolks, whisking constantly.
Pour tempered yolk mixture into the skillet, stirring until sauce thickens slightly. Do not boil.
Add cooked tortellini and crispy bacon back to the skillet, tossing to coat in the sauce.
Season with salt and pepper, garnish with parsley, and serve immediately.
