Pasta Ricotta e Limone

A cold-fold pasta sauce built from ricotta, lemon zest, and Parmigiano Reggiano. The technique is the same as pasta al pesto: the sauce is never cooked — it is assembled in a bowl and the hot pasta melts everything together. Ready in 15 minutes with no active cooking beyond boiling pasta.

Ingredients (4 servings)

  • 320g dry pasta (spaghetti, linguine, or rigatoni)
  • 250g fresh ricotta (ricotta vaccina)
  • 2 lemons — zest of both, juice of 1
  • 50g Parmigiano Reggiano DOP, finely grated
  • 2g black pepper (pepe nero), freshly cracked
  • Salt

Instructions

1. Make the ricotta base In a large serving bowl, combine the ricotta, lemon zest, lemon juice (from 1 lemon), and half the Parmigiano. Season with salt and cracked black pepper. Stir to a smooth, loose paste. The bowl will be used for finishing the pasta — set it aside near the stove so it stays warm.

2. Cook the pasta Bring a large pot of well-salted water to a boil. Cook pasta to 1 minute less than package time.

3. Combine off heat Before draining, ladle 150ml of pasta cooking water into the ricotta bowl and stir — the hot water loosens the mixture. Drain the pasta and transfer immediately to the bowl. Toss vigorously for 60–90 seconds. Add more pasta water in small amounts to achieve a creamy, coating consistency. The sauce should cling to the pasta without pooling.

4. Finish and serve Scatter the remaining Parmigiano over the top. Add a final grind of black pepper. Serve immediately — the sauce thickens quickly as it cools.

Notes

Do not reheat the ricotta sauce on the stove. Ricotta breaks when boiled: the proteins coagulate and the whey separates, producing a grainy result that cannot be recovered. The pasta water is the only heat source the sauce needs.

The zest of both lemons and the juice of only one is the standard ratio. Using juice from both lemons risks overpowering the ricotta — adjust to taste.

This is a vegetarian dish. It does not pair with cheese-and-meat combinations.

Cost Context

At Italian supermarket prices (Q1 2025): pasta-secca (€1.65/kg), ricotta (€6.50/kg), limone (€2.20/kg), parmigiano-reggiano (€17.50/kg), pepe-nero (€20.00/kg). Total for 4 servings: approximately €3.51 — roughly €0.88 per serving.

Ricotta (€1.63 for 250g) is the dominant cost at approximately 46% of total ingredient spend. Compare to pasta al pesto (€0.74/serving, similar cold-sauce technique) and pasta cacio e pepe (€0.43/serving, Parmigiano-and-pepper base without dairy richness).
