Cooking steps
  1. 1

    Bring a large pot of water to a rolling boil; season with 1 tsp salt. Peel and cube the potatoes into 1-inch pieces.

  2. 2

    Add potatoes to boiling water and cook over medium-high heat for 8 minutes. Add trenette pasta and simmer for 4 minutes.

  3. 3

    Add green beans to the pot and continue cooking for another 6–7 minutes, until pasta is al dente, beans are crisp-tender, and potatoes are soft. Drain, reserving 0.5 cup pasta water.

  4. 4

    Meanwhile, for the pesto: In a food processor, blend basil, pine nuts, garlic, and remaining 0.5 tsp salt on low speed. Slowly stream in olive oil for an emulsified, creamy texture. Pulse in Parmesan and pecorino cheeses.

  5. 5

    Toss the hot pasta, potatoes, and green beans with pesto in a large bowl. Add reserved pasta water to loosen, tossing vigorously to coat. Season with black pepper and serve immediately.

Personalized Q&A
Q. What's the key ingredient in this recipe?
The core ingredient in Trenette al Pesto is the homemade basil pesto, which combines fresh basil leaves, pine nuts, garlic, Parmesan, and pecorino cheeses. These give the dish its signature herbaceous, creamy flavor and set it apart from simple pasta recipes.
Q. How should I control the heat to ensure perfect texture?
Use medium-high heat to boil the potatoes, pasta, and green beans together, monitoring the timing closely: potatoes go in first, then pasta, and finally beans. This sequence ensures potatoes become tender without overcooking green beans, and trenette pasta stays perfectly al dente.
Q. How can I prevent the pasta from becoming mushy or sticky?
Drain the cooked pasta, potatoes, and beans as soon as the pasta reaches al dente. Toss everything immediately with pesto and a splash of reserved pasta water, which prevents stickiness and ensures a silky sauce.
Q. How many calories and what is the macronutrient breakdown per serving?
Each serving provides approximately 520 kcal, with carbohydrates at 73g (56%), protein at 13g (10%), and fat at 20g (34%). This offers a balanced profile suitable for vegetarian and Mediterranean diets.
