Restaurant-Style Creamy Pappardelle with Wild Mushrooms & Spinach | Beurre Blanc Method

Instructions

1. 1

   Begin mise en place: mince garlic into two separate piles (2 cloves for beurre blanc, 3 for mushrooms), slice mushrooms uniformly to ¼-inch thickness, hand-tear spinach, and measure all liquids into separate containers for controlled incorporation.

2. 2

   Bring 6 quarts of salted water (2 tablespoons sea salt) to a rolling boil over high heat in a large pot, then add fresh pappardelle and cook for 2-3 minutes until al dente with a slight firm bite (or 8-9 minutes for dried pasta), reserving 1 cup of pasta water before draining.

3. 3

   While pasta cooks, heat 2 tablespoons butter in a large stainless-steel skillet over medium-high heat until foaming subsides, then add mushroom slices in a single layer and resist stirring for 3-4 minutes to develop golden fond on the pan bottom.

4. 4

   Toss mushrooms and continue cooking without crowding for another 2-3 minutes until deep caramel color appears on the edges, then season with ¼ teaspoon fleur de sel and 2 cloves minced garlic, stirring constantly for 30 seconds until fragrant.

5. 5

   Deglaze the skillet with dry white wine by pouring it slowly while scraping the fond with a wooden spoon, then allow to reduce over medium-high heat for 2 minutes until the liquid becomes syrupy and the raw alcohol flavor dissipates, setting mushrooms aside in a bowl.

6. 6

   In the same skillet, reduce heat to medium and add the remaining 2 cloves minced garlic directly to the pan residue, stirring for 15 seconds, then whisk in the cornstarch using a small sifter to create a smooth paste.

7. 7

   Temper the milk by warming it separately in a small saucepan to 120°F, then add it slowly to the starch mixture while whisking vigorously to prevent lumping, continuing to stir for 1 minute until completely smooth.

8. 8

   Pour in the heavy cream while whisking continuously, then adjust heat to medium-low and maintain a gentle simmer for 3-4 minutes, stirring with a rubber spatula every 30 seconds, until the sauce coats the back of a spoon and leaves a clear trail when you draw your finger across it.

9. 9

   Season the sauce deliberately in layers: add ½ teaspoon fleur de sel, whisk for 10 seconds to fully incorporate, then add the freshly ground black pepper and microplaned nutmeg, tasting after each addition and adjusting if needed.

10. 10

    Remove from heat and allow the sauce to cool slightly to 160°F (about 1 minute), then fold in the hand-torn spinach using a gentle spatula motion for 90 seconds until fully wilted and the vibrant green color sets.

11. 11

    Perform the final emulsification: whisk the grated Parmigiano-Reggiano into the sauce in three additions, adding the next portion only after the previous batch has fully melted and incorporated, ensuring a silky, cohesive texture.

12. 12

    Create a finishing beurre blanc by whisking the 4 tablespoons of cold European butter into the sauce one tablespoon at a time, off the heat, waiting 5 seconds between additions for proper emulsification—the sauce should become glossy and coat your whisk.

13. 13

    Add the cooked pappardelle to the sauce and toss gently for 20 seconds using pasta tongs, then add reserved pasta water one tablespoon at a time while tossing, using only enough liquid to achieve a flowing, creamy consistency that clings to each ribbon.

14. 14

    Return the sautéed mushrooms to the pan, folding them in carefully with a final toss to distribute evenly throughout the pasta.

15. 15

    Plate immediately in warmed shallow bowls by twirling pasta onto a carving fork and transferring to the center of each bowl, creating height and visual elegance, then spoon extra sauce around the perimeter.

16. 16

    Garnish each plate with a small nest of fresh parsley chiffonade at the peak of the pasta, scatter 3-4 Parmigiano-Reggiano shards on top, add a light grating of fresh nutmeg, and finish with 2-3 grains of Maldon sea salt flakes on the sauce, then drizzle ½ teaspoon of peppery extra virgin olive oil around the rim for accent and aroma.
