Step 1

Bring a large pot of salted water to a boil over high heat.

Step 2

Heat the olive oil in a large skillet over medium-high heat. Add the pancetta and sauté, stirring occasionally, until rendered, about 3 minutes. Drain and discard half the fat, then add the garlic and shallot to the remaining fat and cook until aromatic, stirring, about 1 minute; season with some salt.

Step 3

Add the asparagus, corn, favas and red pepper flakes to the skillet and sauté for about a minute. Stir in the tomatoes and allow to blister and break down a little. Stir in the kale and cook just until it wilts, then swirl in the butter to melt.

Step 4

Add the pasta to the boiling water and cook until al dente, 45 seconds to 1 minute, then strain, reserving 1/2 cup of the cooking water. Toss the pasta in the sauce, adding some cooking water if needed to moisten. Garnish with some basil and Parmesan shavings, and serve.
