Portobello Mushroom Pappardelle Recipe
Introduction
Portobello Mushroom Pappardelle is a rich and earthy pasta dish that combines tender mushrooms with fresh herbs and a savory tomato-based sauce. This comforting meal is perfect for a cozy night in or when you want to impress with simple yet elegant flavors.

Ingredients
- 3 tablespoons (45 ml) extra-virgin olive oil
- 2 medium shallots, halved lengthwise and thinly sliced (about 2 ounces each)
- Kosher salt
- 3 (350 g) portobello mushroom caps (10-12 ounces), sliced into 1-inch pieces
- 8 ounces (225 g) pappardelle pasta, fresh or dried
- 1 garlic clove, finely sliced
- 2 teaspoons finely chopped fresh rosemary leaves
- ½ teaspoon crushed red pepper
- 2 tablespoons (30 g) tomato paste
- 1 teaspoon balsamic vinegar
- 2 tablespoons (30 g) unsalted butter
- 1 chunk (50 g) Parmigiano Reggiano or Parmesan cheese
Instructions
- Step 1: Heat the olive oil in a large skillet over medium heat. Add the shallots and a pinch of kosher salt. Cook, stirring frequently, until the shallots are softened but not browned.
- Step 2: Add the sliced portobello mushrooms to the skillet. Cook for several minutes until the mushrooms start to brown, then stir and sprinkle with ½ teaspoon kosher salt. Continue cooking until the mushrooms are tender and their liquid has evaporated.
- Step 3: Meanwhile, bring a large pot of water to a boil. Add 2 tablespoons of kosher salt and cook the pappardelle pasta until al dente according to package instructions. Reserve ¾ cup of the pasta water, then drain the pasta.
- Step 4: To the mushrooms, add the garlic, rosemary, crushed red pepper, tomato paste, balsamic vinegar, and butter. Pour in ½ cup of the reserved pasta water and stir over medium heat until the sauce is smooth and glossy.
- Step 5: Add the cooked pasta to the skillet and toss gently with tongs to coat it evenly with the sauce. Add more pasta water if the sauce seems too dry. Taste and adjust seasoning as needed.
- Step 6: Use a vegetable peeler to shave curls of Parmigiano Reggiano over the pasta before serving.
Tips & Variations
- If cooking for larger portions or using one pound of pasta, increase the shallots to 3 and the portobello mushrooms to 4 or 5. Double the tomato paste, balsamic vinegar, and butter, and add up to 1 cup of pasta water to adjust consistency.
- For a creamy twist, stir in a splash of heavy cream or a sprinkle of grated Pecorino Romano before serving.
- Fresh pappardelle works beautifully, but dried pasta is a convenient and tasty alternative.
Storage
Store any leftover pasta and sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat, adding a splash of water or broth to loosen the sauce if necessary.

FAQs
Can I use other types of mushrooms?
Yes, you can substitute cremini or shiitake mushrooms if portobellos are not available. Mixed wild mushrooms also add great flavor.
Is it necessary to save pasta water?
Reserving pasta water is important because it contains starch that helps the sauce cling to the pasta and creates a silky texture. Add it gradually to achieve the right consistency.

Ingredients
For the Sauce
- 3 tablespoons (45 ml) extra-virgin olive oil
- 2 medium shallots, halved lengthwise and thinly sliced (about 2 ounces each)
- Kosher salt, to taste
- 3 (350 g) portobello mushroom caps (10–12 ounces), sliced into 1-inch pieces
- 1 garlic clove, finely sliced
- 2 teaspoons finely chopped fresh rosemary leaves
- ½ teaspoon crushed red pepper
- 2 tablespoons (30 g) tomato paste

- 2 tablespoons (30 g) unsalted butter
Pasta
- 8 ounces (225 g) pappardelle pasta, fresh or dried
Toppings
- 1 chunk (50 g) Parmigiano Reggiano or Parmesan cheese, for shaving
Instructions
- Sauté Shallots: Heat the olive oil in a large skillet over medium heat. Add the halved and thinly sliced shallots along with a pinch of kosher salt. Cook, stirring frequently, until the shallots soften and become translucent but do not brown, about 3-4 minutes.
- Cook Mushrooms: Add the sliced portobello mushrooms to the skillet. Cook for a few minutes until they start to brown and release moisture. Stir occasionally and add ½ teaspoon kosher salt. Continue cooking until the mushrooms are tender and their liquid has evaporated, about 8-10 minutes.
- Boil Pasta: While the mushrooms cook, bring a large pot of water to a boil. Add 2 tablespoons kosher salt to the boiling water. Cook the pappardelle pasta until al dente according to package instructions, usually 4-6 minutes for fresh pasta or 10-12 minutes for dried. Reserve ¾ cup of the pasta water before draining.
- Make Sauce: To the mushroom mixture, add the sliced garlic, finely chopped rosemary, crushed red pepper, tomato paste, balsamic vinegar, and unsalted butter. Pour in ½ cup of the reserved pasta water and stir over medium heat until the sauce thickens and becomes glossy.
- Combine Pasta and Sauce: Add the drained pasta to the skillet with the sauce. Toss gently with tongs to evenly coat the pasta with the sauce. Add more reserved pasta water as needed to achieve the desired sauce consistency. Adjust seasoning with salt to taste.
- Serve: Using a vegetable peeler, shave curls of Parmigiano Reggiano cheese over the pasta just before serving. Serve immediately while warm.
Notes
- Leftover pasta and sauce can be refrigerated and kept for up to 3 days.
- This sauce is designed to coat up to 8 ounces of pasta. For larger servings or if cooking 1 pound of pasta, increase shallots to 3, add 1-2 additional portobello mushrooms, and double the tomato paste, balsamic vinegar, and butter. Use up to 1 cup of reserved pasta water as needed for consistency.
