Creating Caramelized Onion Pasta with Chili Oil is simple if you follow these easy steps:

1. Cook Pasta: Begin by boiling a large pot of salted water. Add the pasta and cook according to package instructions until al dente. Reserve 1 cup of pasta water before draining.
2. Caramelize Onions: While the pasta cooks, heat olive oil in a large skillet over medium heat. Add the sliced onions and a pinch of salt. Cook for about 15-20 minutes, stirring occasionally, until the onions are golden brown and caramelized.
3. Add Garlic: Once the onions are caramelized, add minced garlic to the skillet. Cook for an additional 1-2 minutes until fragrant.
4. Combine Pasta and Sauce: Add the drained pasta to the skillet with the caramelized onions. Toss to combine, adding reserved pasta water as needed to create a silky sauce.
5. Add Chili Oil: Drizzle chili oil over the pasta, tossing to coat evenly. Adjust the amount of chili oil according to your spice preference.
6. Season: Taste and season with salt and pepper as needed.
7. Garnish: Remove from heat and garnish with fresh basil or parsley. Serve immediately, topped with grated Parmesan cheese if desired.
