Mushrooms and spinach together is always a match made in heaven. I use a mix of wild and regular white or cremini mushrooms for this, but don’t hesitate to make it if regular mushrooms are all that is available.
1/2 ounce (about 1/2 cup) dried porcini mushrooms
2 tablespoons extra virgin olive oil
1/2 medium onion or 2 shallots, chopped
2 garlic cloves, minced
1 pound mixed regular and wild mushrooms or 1 pound regular white or cremini mushrooms, trimmed and cut in thick slices (or torn into smaller pieces, depending on the type of mushroom)
Salt and freshly ground pepper
1/4 cup fruity red wine, such as a Côtes du Rhone or Côtes du Luberon
2 teaspoons chopped fresh thyme or a combination of thyme and rosemary
6 ounces baby spinach or 12 ounces bunch spinach (1 bunch), stemmed and thoroughly cleaned
3/4 pound penne
Freshly grated Parmesan to taste
1. Place the dried mushrooms in a Pyrex measuring cup and pour on 2 cups boiling water. Let soak 30 minutes, while you prepare the other ingredients. Place a strainer over a bowl, line it with cheesecloth or paper towels, and drain the mushrooms. Squeeze the mushrooms over the strainer to extract all the flavorful juices. Then rinse the mushrooms, away from the bowl with the soaking liquid, until they are free of sand. Squeeze dry and set aside. If very large, chop coarsely. Measure out 1 cup of the soaking liquid and set aside.
2. Heat the olive oil in a large, heavy, nonstick skillet over medium heat and add the onion or shallots. Cook, stirring often, until tender, about 5 minutes. Turn up the heat to medium-high and add the fresh mushrooms. Cook, stirring often, until they begin to soften and sweat, about 5 minutes. Add the garlic and salt to taste, stir together for about 30 seconds, then add the reconstituted dried mushrooms and the wine and turn the heat to high. Cook, stirring, until the liquid boils down and glazes the mushrooms. Add the herbs and the mushroom soaking liquid. Bring to a simmer, add salt to taste, and cook over medium-high heat, stirring often, until the mushrooms are thoroughly tender and fragrant. Turn off the heat, stir in some freshly ground pepper, taste and adjust salt.
3. Bring a large pot of water to a boil and salt generously. Fill a bowl with ice water. Add the spinach to the boiling water and blanch for 20 seconds only. Remove with a skimmer and transfer to the ice water, then drain and squeeze out water. Chop coarsely and add to the mushrooms. Reheat gently over low heat.
4. Bring the water back to a boil and cook the pasta al dente following the timing suggestions on the package. If there is not much broth in the pan with the mushrooms and spinach, add a ladleful of pasta water. Drain the pasta, toss with the mushrooms and spinach, add Parmesan to taste, and serve at once.
Yield: Serves 4
Advance preparation: The mushroom ragout will keep for 3 or 4 days in the refrigerator and tastes even better the day after you make it.
