Pasta With Butternut Squash, Kale and Brown Butter

Preparation

1. Step 1

   Bring a large pot of salted water to a boil. Meanwhile, in a large Dutch oven or skillet, heat half the oil over medium-high. Add half the squash in a single layer, season with salt and cook, undisturbed, until browned underneath, 3 to 5 minutes. Scoot the squash to the side of the pot, piling it up as needed to make room, then add the remaining oil. Arrange the remaining squash in a single layer, season with salt and cook until browned, 3 to 5 minutes. (If there’s not enough room for the second batch, remove the browned squash to a plate while you cook the rest.)

2. Step 2

   When the water comes to a boil, add the pasta and cook according to package directions until al dente. During the last 3 minutes of the cooking, add the kale. Reserve 1 cup of the pasta water, then drain the pasta.

3. Step 3

   When all the squash is browned, return all the squash to the pot, if you set any aside while cooking the second batch. Reduce the heat to medium-low, add the butter and stir with the squash until the butter is golden, nutty smelling and foaming, 1 to 4 minutes. (If you’re using a dark pot, it can be hard to tell if the butter’s browned, so spoon some of the butter on the squash to see if the butter’s speckled brown.) Turn off the heat, add the garam masala and red-pepper flakes, and stir until fragrant, about 1 minute. Add 1 tablespoon of cold water (or an ice cube) and toss gently to stop the cooking, then set aside until the pasta is ready.

4. Step 4

   Add the pasta and ½ cup pasta water to the squash mixture. Set over low heat and toss gently until the pasta is glossed with sauce. (Some squash pieces might break apart, which can be a good thing: better disbursement through the pasta.) If the pasta looks dry, add more pasta water as needed. Remove from heat and stir in the lemon zest and juice. Season to taste with more lemon juice, red-pepper flakes and salt. Top servings with grated Parmesan.
