Creamy Asparagus and Prosciutto Sauce

Steps

1. 1

   Prepare the ingredients

   • Trim the asparagus by snapping off the woody ends at the natural breaking point (usually the bottom 1–2 inches / 2.5–5 cm).
   • Rinse and cut the tender parts into 1-inch (2.5 cm) pieces.
   • Mince the garlic cloves.
   • Juice the lemon into a small bowl (you'll need about 3 tablespoons / 45 ml) and finely zest it into another small bowl (about 2 teaspoons / 3 g).
   • Slice the prosciutto into thin strips if it isn't already.

   Tip: Snapping asparagus at its natural breaking point ensures you remove only the tough, woody ends and keep all the tender, delicious spears.

2. 2

   Render the prosciutto

   • Place the prosciutto strips in a 12-inch (30 cm) skillet over medium heat.
   • Cook, stirring occasionally, for 3–4 minutes.
   • You're looking for the prosciutto to become crispy at the edges and golden, and the fat to render out into the pan, creating a rich, porky aroma.
   • Transfer the prosciutto to a small plate using a slotted spoon, leaving all the rendered fat in the pan.

   Tip: Don't discard the rendered prosciutto fat—it's liquid gold for flavor.

3. 3

   Cook garlic and asparagus

   • Add 2 tablespoons (30 g) of the butter to the pan with the prosciutto fat.
   • Once melted and foamy, add the minced garlic and cook for about 30 seconds until fragrant.
   • Immediately add all the asparagus pieces and stir for about 1 minute to coat them thoroughly in the fat and heat.

   Tip: Garlic burns easily on its own, so add the asparagus quickly after the garlic to prevent browning.

4. 4

   Simmer asparagus

   • Let the asparagus simmer over medium heat, stirring occasionally, for 5–7 minutes.
   • You're looking for the pieces to turn a bright, vibrant green and become tender but still with a slight resistance when you pierce them with a knife or fork.
   • The center should be just cooked through, not mushy.
   • This keeps the asparagus elegant and prevents it from falling apart when you toss it with the pasta.

   Ready when: asparagus is bright green and tender-crisp, pierced easily but still with slight resistance

   Tip: Overcooked asparagus becomes mushy and dull; these first 5–7 minutes are crucial for keeping the sauce elegant.

5. 5

   Build the cream sauce

   • Pour the heavy cream and lemon juice into the pan with the asparagus, stirring gently to combine everything.
   • Bring the mixture to a gentle simmer over medium-high heat, about 2–3 minutes.
   • You'll notice the sauce beginning to thicken slightly as it heats and the cream starts to bubble gently around the edges.
   • Taste the sauce and season it with salt and freshly ground black pepper.
   • Remember that the prosciutto and cheese will add saltiness, so taste before adding too much.

   Ready when: cream is warm and bubbling gently at the edges; sauce has thickened slightly

   Tip: Don't let the cream boil hard, or it may break and look curdled instead of silky.

6. 6

   Finish the sauce

   • Remove the pan from the heat.
   • Crumble or stir in the reserved prosciutto.
   • Add the lemon zest and the remaining 1 tablespoon (15 g) of butter, stirring until the butter is completely melted and the sauce looks silky and glossy.
   • If using Parmigiano-Reggiano, stir in about 2 tablespoons (20 g) now.
   • Taste and adjust seasoning if needed.
