Time 55m

Yield 6 to 8 servings

Number Of Ingredients 16

1 pound rigatoni
Kosher salt
2 tablespoons extra-virgin olive oil
1 pound assorted mushrooms, stemmed, sliced into 1/3-inch pieces
3 tablespoons unsalted butter
3 cloves garlic, smashed and peeled
3 tablespoons all-purpose flour
3 cups whole milk
2 1/2 cups grated Parmesan
2 cups grated Gruyere
2 cups chopped Tuscan kale (3 to 4 leaves)
1 cup grated Gruyere
1 cup panko breadcrumbs
1/2 cup smoked almonds, chopped
1/4 cup extra-virgin olive oil
2 teaspoons lemon zest (2 lemons)

Steps:

Preheat the oven to 375 degrees F.
For the pasta: Cook the rigatoni in a large pot of generously salted boiling water until al dente, about 3 minutes less than the package directions. Drain, reserving 1/2 cup of the cooking water.
Heat the olive oil over medium-high heat in a large Dutch oven. Sear the mushrooms, undisturbed, for 3 minutes; stir, and season with 1 teaspoon salt. Sear on the reverse side an additional 2 minutes. Remove the mushrooms from the pan.
Lower the heat to medium and melt the butter in the Dutch oven. Add the garlic and flour, and cook, stirring, for 1 minute. Whisk in the milk and simmer gently until the sauce just thickens, 5 minutes. Remove from the heat and add the Parmesan, Gruyere and 1/2 teaspoon salt. Let cool slightly, then add half of the seared mushrooms, and puree with an immersion blender.
In a large bowl, toss the pasta with the sauce and the remaining half of the mushrooms, adding about 1/4 cup of the reserved pasta water or more if desired. Transfer to a baking dish.
For the gremolata: In a medium bowl, combine the kale, Gruyere, panko, smoked almonds, olive oil and lemon zest.
Scatter the gremolata over the pasta and bake until golden on top and bubbling, about 40 minutes.
