Ingredients:
- 3 tablespoons extra-virgin olive oil

- Kosher salt
- 10-12 ounces portobello mushroom caps (sliced into 1-inch pieces)
- 8 ounces fresh or dried pappardelle pasta
- 2 tablespoons tomato paste
- 2 finely sliced garlic cloves
- 2 teaspoons finely chopped fresh rosemary leaves
- ½ teaspoon crushed red pepper
- 2 teaspoons balsamic vinegar
- 3 tablespoons unsalted butter
- 1 chunk Parmigiano Reggiano or Parmesan cheese
Cooking Instructions
Prepare the Mushrooms and Aromatics
We’re starting by building a rich, earthy base for our pappardelle. First, get your portobello mushrooms prepped. Wipe them clean with a damp paper towel; no need to wash them as they can absorb too much water. Then, slice the caps into substantial 1-inch pieces. We want them to have a nice bite and absorb all that delicious sauce. Next, thinly slice your shallots. You’re looking for about half a cup in total. Shallots have a milder, sweeter flavor than onions, which will complement the mushrooms beautifully. Don’t forget to finely slice your garlic cloves; two should be just right to add a punch without being overpowering. Finely chop your fresh rosemary leaves – about two teaspoons’ worth. Fresh rosemary is really key here for its piney, robust aroma.
Sauté the Mushrooms
In a large skillet or Dutch oven, heat the 3 tablespoons of extra-virgin olive oil over medium-high heat. Once the oil is shimmering, add your sliced portobello mushrooms. Spread them out in a single layer as much as possible. Don’t crowd the pan; if you have to, cook them in two batches. This is important for getting a good sear on the mushrooms, which develops their flavor and prevents them from becoming watery and sad. Let them cook undisturbed for about 3-4 minutes until they start to brown. Then, give them a stir and continue cooking for another 5-7 minutes, until they’re tender and nicely browned. Season them generously with kosher salt. Once they’re done, scoop the mushrooms out of the skillet and set them aside on a plate. They’ll rejoin the sauce later.
Build the Sauce Base
Lower the heat to medium and add the 2 tablespoons of tomato paste to the same skillet. Stir it around, letting it cook for about 1-2 minutes until it darkens slightly. This step is called ‘toasting’ the tomato paste and it really deepens its flavor, getting rid of any raw taste. Now, add the 2 medium thinly sliced shallots to the skillet. Cook them, stirring frequently, until they’re softened and translucent, which should take about 3-4 minutes. Next, add the 2 finely sliced garlic cloves and the ½ teaspoon of crushed red pepper. Stir and cook for about 30 seconds until the garlic is fragrant. Be careful not to burn the garlic, or it can turn bitter. This is where the magic starts to happen, creating a deeply flavored foundation.
Incorporate Liquids and Herbs
Pour in the 2 teaspoons of balsamic vinegar. Stir it into the shallots and garlic, scraping up any browned bits from the bottom of the pan – that’s where a lot of flavor is hiding. Let the balsamic vinegar reduce for about 30 seconds. Now, add the 2 teaspoons of finely chopped fresh rosemary leaves. Give it a good stir. If the pan seems a little dry, you can add another tiny drizzle of olive oil, but usually the residue from the mushrooms is enough. We’re building layers of flavor here, and this combination of balsamic, rosemary, and the toasted tomato paste is fantastic.
Cook the Pappardelle and Finish the Dish
While the sauce base is simmering, bring a large pot of generously salted water to a rolling boil for your 8 ounces of fresh or dried pappardelle pasta. Cook the pasta according to package directions until it’s al dente. Fresh pappardelle cooks very quickly, often in just 2-4 minutes, so keep a close eye on it. If you’re using dried, it will take longer. Just before draining the pasta, reserve about 1 cup of the starchy pasta water. Drain the pasta well. Return the skillet with the sauce base to medium heat. Add the cooked mushrooms back into the skillet. Then, add the drained pappardelle to the skillet. Toss everything together to coat the pasta evenly with the sauce. If the sauce seems a little thick, add a splash of the reserved pasta water, a tablespoon at a time, to loosen it up and help the sauce cling to the pasta. Stir in the 3 tablespoons of unsalted butter until it’s melted and the sauce is glossy. Taste and adjust seasoning with more kosher salt if needed. Serve immediately, gratinating a generous amount of Parmigiano Reggiano or Parmesan cheese over each serving. The nutty, salty cheese is the perfect finishing touch.

Conclusion:
This Portobello Mushroom Pappardelle is a wonderfully satisfying dish that’s perfect for a weeknight meal or a casual dinner party. The earthy mushrooms, combined with the rich sauce and tender pappardelle, create a comforting and flavorful experience that’s hard to beat. It proves that delicious, hearty meals don’t need to be complicated. I hope you give it a try and discover how easy it is to make something truly special in your own kitchen.
Serving Suggestions: This pasta is fantastic on its own, but a simple side salad with a light vinaigrette or some crusty bread to sop up any extra sauce would be wonderful accompaniments. A sprinkle of fresh parsley can also add a nice touch of color.
Variations: Feel free to add other vegetables like spinach, kale, or even some roasted red peppers. For a non-vegetarian version, crispy beef pancetta or beef prosciutto can be added at the end. If you don’t have pappardelle, fettuccine or even linguine will work well.
FAQ: Can I use dried mushrooms instead of fresh portobellos?
Yes, you can rehydrate about 2-3 ounces of dried porcini or mixed wild mushrooms and use them. Make sure to reserve the soaking liquid (strained) to add to the sauce for extra depth of flavor.
FAQ: What if I don’t have shallots?
You can substitute with one small yellow onion or two green onions (white and light green parts only), finely chopped. The flavor will be slightly different but still delicious.
