Creamy Shells with Cheese & Nuts

This pasta shells dish is the kind of weeknight Italian that feels fancier than the effort required. Cooked al dente shells get tossed in melted butter and silky mascarpone, then finished with sharp parmesan and a generous handful of toasted walnuts for crunch.

No flour, no roux, no long simmer. The mascarpone is the sauce, melting smoothly into the warm pasta and clinging to the shell ridges so every bite carries cheese and a bit of nut.

Chef Tips

• Cook the pasta a minute shy of al dente. It will finish in the warm sauce and shouldn’t go past tender.
• Reserve a half cup of pasta water before draining. A splash loosens the sauce if it tightens up too much.
• Don’t let the mascarpone boil. High heat splits it and the silky texture turns grainy. Warm gently and remove from the heat as you toss.
• Toast the walnuts in a dry skillet for 3 to 4 minutes before chopping. The flavor difference between raw and toasted is significant.
• Use a fireproof or oven-safe serving dish if possible. The residual heat keeps the sauce silky from kitchen to table.

Variations

• Swap walnuts for toasted pine nuts or chopped hazelnuts for a different nutty profile.
• Stir in 1 tablespoon fresh chopped sage or a pinch of nutmeg for a classic Northern Italian touch.
• Add a handful of arugula or wilted spinach at the end for color and a peppery contrast.
