Pasta al Pesto (No Pine Nuts)

This basil pesto pasta is made without pine nuts — a deliberate budget choice. Traditional pesto genovese includes pinoli (€40+/kg); omitting them keeps the cost at €0.74 per serving without significantly altering the flavour. The cold-sauce technique is the same: fresh basil, Parmigiano Reggiano, garlic, and olive oil worked into a paste and loosened with hot pasta water at the moment of serving. Heat destroys basil's aromatic compounds; the sauce must never reach the stove.

Ingredients (4 servings)

• 320g dry pasta (trofie is traditional; spaghetti or linguine work)
• 80g fresh basil leaves, loosely packed
• 50g Parmigiano Reggiano DOP, finely grated
• 5g garlic (1 small clove)
• 60ml extra virgin olive oil

Instructions

1. Make the pesto Combine the basil leaves, garlic, and a pinch of salt in a food processor or mortar. If using a food processor, pulse rather than blend continuously — extended blending heats the basil and darkens the colour. Add the Parmigiano and olive oil gradually and work into a coarse paste. The texture should remain slightly grainy, not smooth.

2. Cook the pasta Bring a large pot of water to a boil. Salt generously. Cook pasta to package instructions. Reserve 100ml of pasta water before draining.

3. Combine off heat Drain the pasta. Remove from any heat source. Transfer to a bowl. Add 3–4 tablespoons of the hot pasta water to the pesto and stir quickly — the heat from the water loosens the pesto without cooking it. Pour the pesto over the pasta and toss until every strand is coated. Add more pasta water as needed to achieve a glossy coating.

4. Serve Serve immediately. Additional grated Parmigiano at the table.

Notes

To make traditional pesto genovese, add 30g of pine nuts (pinoli) to the paste — this raises the cost by approximately €1.20 for 4 servings. Traditional recipes also include a small amount of Pecorino Romano alongside the Parmigiano. The version here omits both to produce a costed, reproducible baseline.

Fresh basil quality is the single variable most affecting the outcome. Wilted or refrigerator-damaged basil produces a dark, bitter sauce with no remedy.

Cost Context

At Italian supermarket prices (Q1 2025), the ingredient cost for 4 servings is approximately €2.97 — roughly €0.74 per serving. Fresh basil (€0.96) and Parmigiano Reggiano (€0.88) are the two dominant cost drivers, together representing 62% of total cost. Compare to pasta al pomodoro at approximately €0.30/serving — pesto is roughly 2.5× more expensive.
