Best Portobello Mushroom Recipes, Including Mushroom Spinach Pasta

0 Bring a large pot of salted water to a boil. 
1 Place a large (12-inch) pan over medium heat. Add the olive oil and shallots to the pan along with ½ teaspoon kosher salt. Cook until the shallots are softened, stirring frequently, about 5 minutes.
2 Add the mushrooms to the pan in one layer. Cook undisturbed for 5 minutes, then sprinkle with ½ teaspoon salt and stir them around with the shallots. Stir in the garlic, chili and black pepper and continue cooking 5 more minutes, or until they are softened and have released their juices.
3 While the mushrooms cook, add the pasta to the boiling water and cook according to package directions. Note that fresh pasta will usually be done in 2-4 minutes and dried pasta in 10-12 minutes. Drain.
4 Raise the heat under the mushrooms to medium-high and pour in the wine. Let it bubble and cook for 2 minutes. Stir in the butter until it melts. Remove the pan from the heat and add ¼ cup cheese and spinach to the pan. Stir until the leaves are wilted.
5 Add the cooked pasta to the pan and toss gently with the sauce.  Serve in bowls with additional cheese sprinkled over the pasta. Pour a glass of wine and enjoy!
