Step‑by‑Step Instructions for Caramelized Onion Pasta with Chili Oil

Step 1: Caramelize the Onions
Begin by thinly slicing the large yellow onion to ensure even cooking. In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the onions and a pinch of salt, stirring occasionally. Cook for 25-30 minutes until the onions soften and turn a deep golden brown, releasing their sweet aroma. Five minutes before they’re done, stir in the minced garlic for extra flavor.

Step 2: Make the Chili Oil
In a small saucepan, drizzle in 3 tablespoons of olive oil and heat over medium-low heat. Once warm, add the sliced garlic from the chili oil ingredients and sauté until fragrant, about 1-2 minutes. Introduce 1 tablespoon of red chili flakes and 1 teaspoon of paprika, allowing them to infuse for 2-3 minutes. Finally, stir in 1 teaspoon of soy sauce before removing from heat, creating a flavorful chili oil.

Step 3: Cook the Pasta
Bring a large pot of salted water to a rolling boil. Add in 12 ounces of your preferred pasta, cooking according to package instructions until al dente, usually around 8-10 minutes. Before draining, reserve about 1 cup of the starchy pasta water—this will help adjust the sauce later. Drain the pasta and set aside while keeping it warm.

Step 4: Combine the Ingredients
In the skillet with the caramelized onions, add the drained pasta, tossing everything together with a generous drizzle of the chili oil. Mix well to ensure the pasta is evenly coated with the sweet and spicy sauce. If the mixture appears dry, gradually incorporate some of the reserved pasta water until you reach your desired consistency.

Step 5: Garnish and Serve
To finish your Caramelized Onion Pasta with Chili Oil, serve it hot, topped with a sprinkle of grated Parmesan cheese and a handful of chopped fresh basil or parsley for brightness. For those who love an extra kick, add a few more chili flakes on top before enjoying your delicious, warming meal!
