Elevate cacio e pepe pasta with crispy shiitake mushrooms. The trick to crisping the mushrooms is to start them in a cold dry pan. Heating them this way allows the moisture to release, crisping them up, before adding butter for flavor.

Ingredients

Kosher salt

12 ounces spaghetti

7 ounces shiitake mushrooms, stemmed and thinly sliced

2 sprigs fresh thyme

7 tablespoons unsalted butter

1/4 cup olive oil

1 tablespoon plus 1 teaspoon coarsely ground black pepper, plus more for serving

2 cups (1/2 pound) freshly grated Parmesan, plus more for serving

Directions

  1. Bring a large pot of salted water to a boil. Cook the pasta according to the package directions until al dente. Reserve 2 cups of the cooking water then drain the pasta.
  2. While the pasta is cooking, arrange the mushrooms in a large skillet in an even layer. Turn the heat to medium-high and let the mushrooms cook, untouched, until they begin to release their liquid, 3 to 4 minutes. Add the thyme, 3 tablespoons of the butter and 1/2 teaspoon salt. Cook and melt the butter, stirring the mushrooms occasionally, until they are a deep golden brown, have released all their liquid and crisp up, 4 to 5 minutes.
  3. Remove the mushrooms to a plate and reduce the heat to medium-low. Add the olive oil and remaining 4 tablespoons butter to the skillet and heat until the butter is melted and the foam subsides, about 1 minute. Add the 1 tablespoon plus 1 teaspoon pepper and cook, stirring, until lightly toasted, about 1 minute. Add the pasta and 1 1/2 cups of the reserved cooking water to the skillet and toss to coat. Sprinkle the 2 cups Parmesan on top and continue to cook, tossing until the cheese is melted and the pasta is well coated, about 2 minutes. If necessary, add a little more of the reserved cooking water to loosen the sauce. Transfer the pasta to a large bowl and top with the mushrooms. Garnish with more pepper and Parmesan, if desired.

This is the second time I’ve made this dish with shiitake mushrooms purchased from Sam’s club and it is fabulous. I use a plant-based spread instead of butter to keep the cholesterol down. Have fresh thyme from the garden, organic extra virgin olive oil and, as some have recommended, a good squirt of fresh lemon to brighten it up. Don’t put in as much pepper as the recipe states but can always add later. Also, just add grated cheese when serving but I’ve also found that it’s great without it and makes it Vegan. Going to try it with goat cheese and see if it’s even better. It’s simple to make, is earthy and flavorful. Pair it with a salad and makes a satisfying dinner. Thanks for this recipe. It’s a keeper!
