How to Make Caramelized Onion Pasta with Chili Oil: A Sweet and Spicy Flavor Bomb
-
CARAMELIZE THE ONIONS: In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the thinly sliced onion, a sprinkle of salt, and cook, stirring occasionally, for about 15-20 minutes until the onions turn a lovely golden brown. Add the minced garlic in the last couple of minutes and stir until fragrant.
-
MAKE THE CHILI OIL: In another small saucepan, combine 3 tablespoons of olive oil, red chili flakes, paprika, and thinly sliced garlic. Heat gently over low heat until it sizzles slightly, allowing the flavors to meld for about 5 minutes. Stir in the soy sauce to finish.
-
COOK THE PASTA: While the onions are caramelizing, bring a large pot of salted water to a boil and cook the pasta according to package instructions until al dente. Reserve a cup of pasta water, then drain the pasta.
-
COMBINE THE PASTA AND ONIONS: Add the drained pasta to the skillet with the caramelized onions. Pour in the chili oil (discarding the garlic slices if desired), and add a bit of the reserved pasta water to help the sauce coat the noodles. Toss everything gently to combine, seasoning with salt and pepper to taste.
-
GARNISH AND SERVE: Divide the pasta among bowls, sprinkling generously with grated Parmesan and the freshly chopped basil or parsley. For those who love a kick, sprinkle extra chili flakes on top. Enjoy your warm, cozy meal!
