Step 1

Cook the spaghetti in a large pot of salted boiling water until al dente according to package instructions.

Step 2

While the pasta is cooking, heat the olive oil in a large skillet over medium heat. Sauté the kale until the leaves start to soften, about 5 minutes.

Step 3

Add the garlic, red pepper flakes, salt, pepper and lemon zest. Continue cooking until fragrant, about 1 minute. Then add the lemon juice.

Step 4

Use tongs to transfer the spaghetti from the pot to the skillet with the kale. Toss to coat in the olive oil. Stir in the pecorino cheese.

Step 5

Divide onto serving plates or into bowls. Top with additional cheese before serving.
