Ingredients
-
1/4 cup dried porcini mushrooms
-
6 tablespoons extra-virgin olive oil
-
1 small onion, cut into 1/4-inch dice
-
2 medium carrots, peeled and cut into 1/4-inch dice
-
1 baby eggplant (8 ounces), peeled and cut into 1/4-inch dice
-
1 pound cremini mushrooms, one-fourth sliced, the rest cut into 1/4-inch dice
-
8 ounces shiitake mushrooms, stemmed, caps cut into 1/4-inch dice
-
Kosher salt
-
Pepper
-
5 garlic cloves, minced
-
2 tablespoons tomato paste
-
1 tablespoon white miso
-
One 2-inch chunk of Parmigiano-Reggiano cheese, plus grated cheese for serving
-
One 28-ounce can whole peeled tomatoes, crushed
-
1 thyme sprig
-
1/2 teaspoon turbinado sugar
-
12 ounces spaghetti
-
2 tablespoons chopped parsley
Directions
-
In a small bowl, cover the porcini with 1 cup of boiling water; soak until softened, about 30 minutes. Finely chop the porcini, discarding any tough bits. Pour off and reserve 1/2 cup of the soaking liquid.
-
In a large enameled cast-iron casserole, heat 2 tablespoons of the oil. Add the onion and carrots and cook over moderate heat until light golden, about 8 minutes. Add the eggplant and 2 tablespoons of the oil and cook, stirring occasionally, until softened, 8 minutes. Stir in the cremini, shiitake, chopped porcini and the remaining 2 tablespoons of oil and season with salt and pepper. Cook, stirring occasionally, until the mushrooms are golden, 8 to 10 minutes. Stir in the garlic, tomato paste and miso and cook for 2 minutes. Add the chunk of cheese, the tomatoes and their juices, the thyme, sugar and reserved mushroom soaking liquid and bring to a simmer.
-
Cover and cook over low heat, stirring occasionally, until the sauce is very thick, about 1 hour and 30 minutes. Discard the thyme sprig; season the sauce with salt and pepper.
-
In a pot of salted boiling water, cook the spaghetti until al dente. Drain, reserving 1/4 cup of the pasta water.
-
Add the pasta, pasta water and parsley to the sauce; toss to coat. Serve in bowls, topped with grated cheese.
