Spaghetti With Burrata and Garlic-Chile Oil

Bring a large pot of generously salted water to a boil. Crack the fennel seeds with the flat side of a large knife or the backside of a heavy skillet. Heat the oil, sliced fennel, garlic, fennel seeds and red-pepper flakes in a large skillet over low. Cook, stirring occasionally, until the garlic and fennel are softened and the oil is deeply flavored, 12 to 15 minutes.

Meanwhile, cook the pasta according to package directions until al dente. Drain and return pasta to pot. Reserve a few tablespoons of the seasoned oil and fennel mixture, then add the rest to the pot with the pasta and toss to coat.
