Bring a large pot of salted water to a boil. Add the pasta and cook until al dente according to package instructions.
1 lb Pasta
While the pasta cooks, whisk together the ricotta, Romano or Parmesan, olive oil, lemon zest, and lemon juice in a bowl until smooth. Season to taste with salt, pepper, and red pepper flakes.
1 cup Whole milk ricotta, 1 Fresh lemon, 1/4 cup Extra virgin olive oil, 1/2 cup Grated Romano or Parmesan cheese, Kosher salt, Freshly ground black pepper, Red pepper flakes
Reserve 1 cup of pasta water, then drain the pasta and return it to the pot.
Add the ricotta mixture, butter, and about 1/4 cup of pasta water to the pasta. Toss over low heat until the sauce is creamy and coats the noodles.

Add more pasta water as needed until the sauce reaches your desired consistency. Taste and adjust seasoning if needed.
