Ingredients

Scale

For the Pasta:

  • 12 oz pasta (spaghetti, penne, or linguine recommended)
  • 2 tablespoons olive oil
  • 1 large yellow onion, thinly sliced
  • 3 cloves garlic, minced
  • Salt and pepper, to taste

For the Chili Oil:

  • 3 tablespoons olive oil (extra virgin recommended)
  • 1 tablespoon red chili flakes
  • 1 teaspoon paprika
  • 1 small garlic clove, thinly sliced
  • 1 teaspoon soy sauce

For Garnishing:

  • Grated Parmesan cheese
  • Fresh basil or parsley, chopped
  • Extra chili flakes (optional)

Instructions

  1. Caramelize the Onions: Thinly slice the onion into even rings for even cooking. Heat 2 tablespoons of olive oil in a large, deep skillet over medium heat. Add the onions with a pinch of salt to help release moisture, stirring occasionally. Cook for 25-30 minutes, stirring every 5-7 minutes, until the onions are golden and soft. Add minced garlic about 5 minutes before finishing, cooking until fragrant but not burnt. Season with salt and freshly ground black pepper, then set aside.
  2. Make the Chili Oil: Warm 3 tablespoons olive oil in a small saucepan over medium heat. Add the sliced garlic and sauté for 1-2 minutes until fragrant but not browned. Stir in red chili flakes and paprika, cooking for another 2-3 minutes to infuse flavors. Add 1 teaspoon soy sauce, stir well, and simmer for 2 more minutes. Remove from heat and set aside.
  3. Cook the Pasta: Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Before draining, reserve 1 cup of pasta water. Drain pasta and set aside.
  4. Combine Pasta and Onions: Add the caramelized onions to the cooked pasta and stir to coat thoroughly. Drizzle the chili oil over the pasta and toss to combine, ensuring every noodle is glossy. If the mixture appears dry, add reserved pasta water gradually to loosen the sauce.
  5. Garnish and Serve: Generously sprinkle grated Parmesan cheese over the pasta. Add chopped fresh basil or parsley for freshness and color. Optionally, sprinkle extra chili flakes for more heat. Serve immediately while hot as a main dish or with a side salad.

Notes

  • For best results, slice onions evenly to ensure uniform caramelization.
  • Adjust the quantity of red chili flakes to control the spice level.
  • Reserve pasta water before draining to help achieve a smooth sauce consistency.
  • Use extra virgin olive oil in chili oil for best flavor.
  • Parmesan cheese adds creaminess but can be omitted or substituted for a vegan option.
  • Fresh herbs like basil or parsley brighten the dish and add freshness.
