Trofie alla Genovese

1 . Stage

Start by making the pesto: Heat a dry pan over medium-low heat. Add pine nuts and roast, tossing occasionally, until fragrant, 3 to 5 minutes. Transfer to a food processor.

2 . Stage

Add basil, Parmesan cheese, 1/2 cup olive oil, and garlic to the pine nuts; pulse until pesto is smooth. Add more olive oil if pesto is too thick. Season with salt and pepper and let rest for 1 hour.

3 . Stage

Prepare pasta: Bring vegetable stock to a boil in a large pot. Add haricots verts and boil for 5 minutes. Reduce heat to a simmer, add potato, and cook until both are fork-tender, about 20 minutes. Remove vegetables with a slotted spoon, leaving broth in the pot.

4 . Stage

Add trofie pasta to the broth and boil until tender yet firm to the bite, 7 to 8 minutes for dry pasta and 3 to 4 minutes for fresh. Drain.

5 . Stage

Combine potatoes, green beans, and pasta with the reserved pesto and toss together. Plate immediately with a wedge of lemon.
