Start by washing, de-stemming, and slicing your kale into ribbons. Crush the garlic, grate the parmesan, and have everything lined up and ready to go because this comes together fast.
1 medium bunch Tuscan kale, 2 cloves garlic, ½ cup grated Parmesan
Set a large pot of water over high heat and bring to a boil. Salt well, and add your pasta shapes to it. Fresh pasta takes only a few minutes to cook, but if you're using dried you will need to plan for 8-12 minutes of cooking time.
14 oz fresh pasta shapes
When the pasta is al dente, scoop out 1 cup of pasta water and reserve for later. Then, drain the pasta and set aside.
While the pasta is cooking, heat a large heavy-bottomed skillet over medium-high heat. Add the butter, olive oil, garlic, and red pepper flakes. Allow this to cook for 1-2 minutes, until the garlic has just barely started to brown.
1 Tablespoon butter, 1 Tablespoon olive oil, Pinch red pepper flakes
Add the kale ribbons to the garlic butter, and sauté, stirring frequently, until the kale begins to soften - about 2-3 minutes.
1 medium bunch Tuscan kale
Pour the heavy cream into the kale, and stir to combine well. Reduce the heat to medium, and let the kale simmer in the cream for 2-3 minutes.
1 ¼ cups heavy cream
Add the cooked pasta to the kale mixture, along with the lemon zest and Parmesan cheese. Stir to combine well.
Zest of 1 lemon, ½ cup grated Parmesan
Add a bit of pasta water, splash by splash, to loosen the sauce up until it has reached the desired consistency. I find that 2-3 Tablespoons is usually enough.
Serve hot, with extra Parmesan and red pepper flakes for garnish.
