Equipment

  • Large pasta pot At least 6-quart capacity
  • Large skillet or sauté pan 12-inch recommended for proper mushroom searing
  • Colander For draining pasta
  • Wooden spoon or silicone spatula
  • Chef's knife
  • Cutting board
  • Measuring spoons and cups
  • Microplane or box grater For Parmesan and lemon zest
  • Ladle or heatproof mug For scooping pasta water
  • Tongs For tossing pasta

Ingredients
  

  • 12 oz spaghetti or linguine 340g
  • 3 tablespoons extra virgin olive oil divided
  • 4 garlic cloves minced
  • 1 lb cremini or baby bella mushrooms 450g, sliced into 1/4-inch thick pieces
  • 5 oz fresh baby spinach 142g, about 5 packed cups
  • 1/2 teaspoon red pepper flakes optional, for heat
  • 1/2 cup reserved pasta water starchy cooking liquid; scoop before draining
  • 1/2 cup Parmesan cheese freshly grated; about 50g; plus more for serving
  • salt and black pepper to taste

Optional Add-Ins

  • 1 tablespoon unsalted butter optional; adds richness to the sauce
  • 1 lemon optional; zested; brightens the finished dish

For Garnish

  • fresh parsley chopped; for serving
  • extra virgin olive oil drizzle over finished bowls for serving
  • Parmesan cheese extra grated; for serving

Instructions
 

  • Fill a large pot with at least 4 quarts of water, add 1 to 1.5 tablespoons of salt, and bring to a rolling boil over high heat. Cover the pot to speed up the process.
  • Wipe mushrooms clean with a damp paper towel and slice into 1/4-inch pieces. Mince the garlic, zest the lemon if using, and chop the parsley; measure out all remaining ingredients and set aside.
  • Cook the pasta in the boiling salted water according to package directions until al dente, then reserve 1/2 cup of pasta water before draining. Do not rinse the pasta after draining.
  • Heat a large skillet over medium-high heat, add 2 tablespoons of olive oil, then add mushrooms in a single layer and cook undisturbed for 3 to 4 minutes until golden brown. Flip and cook another 2 to 3 minutes; season with salt and pepper.
  • Reduce heat to medium, push mushrooms to the side, and add the remaining 1 tablespoon of olive oil to the clearing. Add minced garlic and red pepper flakes and cook for 30 to 60 seconds until fragrant, then stir into the mushrooms.
  • Add all the fresh spinach to the skillet and fold it into the mushrooms using tongs, cooking for 1 to 2 minutes until just wilted and bright green.
  • Add the drained pasta to the skillet and toss with the mushroom spinach mixture over medium-low heat, adding reserved pasta water a few tablespoons at a time until a light, silky sauce forms. Stir in butter if using.
  • Remove from heat, add the grated Parmesan and lemon zest if using, and toss quickly until the cheese melts into a creamy coating. Taste and adjust seasoning with salt and black pepper.
  • Divide pasta into bowls, top with extra Parmesan, chopped parsley, and a drizzle of olive oil, and serve immediately.

Notes

  • Don't crowd the mushrooms: Cook in batches if needed — overcrowding causes steaming instead of browning and you'll lose the deep umami flavor.
  • Always save pasta water: The starchy liquid is essential for creating a silky sauce without cream; scoop it out before draining every time.
  • Use freshly grated Parmesan: Pre-shredded cheese contains anti-caking agents that prevent smooth melting; grating fresh from the block makes a noticeable difference.
  • Cook pasta to al dente: Pull it 1 to 2 minutes early since it continues to cook in the skillet; overcooked pasta will turn mushy when tossed.
  • Frozen spinach substitute: Thaw completely and squeeze out all excess water before adding to the pan; fresh spinach is strongly preferred for texture and color.
  • Make it creamy: Stir in 1/3 cup of heavy cream or a tablespoon of cream cheese with the Parmesan for a richer, more indulgent sauce.
  • Make it vegan: Omit butter and Parmesan and replace with 2 to 3 tablespoons of nutritional yeast plus a generous drizzle of good olive oil.
  • Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days; this dish is not recommended for freezing due to the spinach.
  • Reheating: Reheat in a skillet over medium heat with a splash of water or olive oil, tossing frequently; finish with fresh olive oil and Parmesan before serving.
  • Mushroom varieties: Cremini are classic, but a blend of shiitake, oyster, and cremini mushrooms produces a more complex, deeply savory result.
