Fill a medium saucepan with water, add a generous amount of kosher salt, and bring to a boil.
You should cook the pasta according to the instructions on the package until it is al dente.
Before draining, reserve ½ cup of the pasta cooking water and set aside.
Heat 2 tablespoons of extra virgin olive oil in a large, deep pan over medium heat until shimmering.
Add the shallots, garlic, and a pinch of salt. Cook, stirring frequently, for about 1 minute.
Stir in the chopped sun-dried tomatoes and cook for another 1–2 minutes until softened.
Pour in the milk and ¼ cup of the reserved pasta water. Cook for 1–2 minutes, stirring occasionally, until warmed through. Add the oregano and red pepper flakes and stir to combine.
Turn off the heat. Add the cooked pasta and Parmesan cheese to the pan. Toss well to coat the pasta evenly. If the sauce is too thick, add a splash more of the reserved pasta water.
Depending on your taste, add more salt and pepper if needed.
Stir in torn fresh basil and serve immediately.
