Linguine with Hot Chile, Caramelized Onion & Gremolata

This pasta has a rich mediteraneon flavour with the combination of lemon, garlic and parsley .

2 tbsp. extra-virgin olive oil

1 large yellow onion, very thinly sliced

1/2 tsp. crushed red pepper flakes

Salt

1 Serrano or other fresh small, hot red or green chile, seeded and finely diced

1/2 cup unsalted butter, cut into about 5 pieces

3 tbsp. fresh lemon juice

1 lb. dried linguine

1/3 cup roughly chopped fresh parsley

1 large clove garlic, finely chopped

1 tsp, finely chopped lemon zest

1/2 cup grated Parmesan cheese; more for garnish


Bring a large pot of well-salted water 10 a boil.

Meanwhile, heat the oil in a 10-inch skillet over medium heat. Add the onion and red pepper flakes, season with a big pinch of salt, and cook, stirring frequently, until tender and nicely browned, about 15 minutes (reduce the heat to medium low if the onion is browning too fast). Add the diced chile and continue to cook for 1 minute. Turn off the heat add the butter, and swirl the pan to melt. Add the lemon juice and another pinch of salt. Keep warm.


Cook the linguine in the boiling water until al dente, about 10 minutes.


Meanwhile, make the Gremolata: Combine the parsley, garlic, and lemon zest on a cutting board and chop them together with a chef's knife until the parsley is finely chopped and mixed well with the lemon and garlic.


Drain the pasta and return it to its cooking pot. Over medium heat, add the onion mixture to the pasta and toss to combine. Add the 1/2 cup Parmesan cheese, quickly toss again, and add salt to taste. Transfer the pasta to a platter or shallow bowls. Sprinkle liberally with the Gremolata and more Parmesan and serve. Makes 4-6 servings.
