Cook and prep the fava beans according to the package and set aside.
Cook the pasta and drain, making sure to reserve a cup of the cooking liquid.
Heat the oil and a pinch of red pepper flake in a large skillet or dutch oven. Saute the garlic for a minute or so.
Add the lemon juice and zest, the cream and the reserved cooking liquid. Adjust the heat so the liquid is just below a boil. Let thicken slightly then add the favas and pasta.
Allow to heat through. Season with salt and pepper to taste.
Just before serving stir in the grated cheese and basil.
