1 pound spaghetti
2 cups chicken stock
2 pinches saffron
1 tablespoon extra virgin olive oil (EVOO)
3 small or 2 medium zucchini (about 3/4 pound), cut into small cubes or thinly sliced
6 tablespoons butter, cut into 6 pieces
1 cup grated Parmigiano Reggiano cheese
Heat your oven to its lowest setting, then place a large pasta platter or bowl inside to warm. Bring a large pot of water to a boil, salt it, add the pasta and cook until al dente. Drain, reserving a ladleful of the pasta cooking water. While the pasta is working, in a medium saucepan, bring the chicken stock and saffron to a boil and cook until reduced to about 1 cup, about 10 minutes. In a medium skillet, heat the EVOO, one turn of the pan, over medium-high heat. Add the zucchini and cook until crisp-tender, about 5 minutes. Remove the platter from the oven and scatter the butter on it. Add the pasta, zucchini and saffron-infused stock, then add the cheese and toss vigorously for 1 minute to form a yellow, glossy sauce. Add the reserved pasta cooking water as desired if the sauce is too thick.
