• Garlic: Adds that irresistible aromatic base to the sauce.
• Olive Oil: For sautéing the onions and garlic. A good-quality olive oil will make a big difference in the flavor.
• Salt and Pepper: To taste, bringing everything together.

For the Chili Oil:

• Olive Oil: The base of the chili oil, it helps carry the flavors and adds richness.
• Dried Chili Flakes: The heat source for the chili oil. Adjust the amount depending on how spicy you like it.
• Garlic: A little extra garlic to infuse the oil with flavor.
• Fresh Herbs (optional): You can add herbs like thyme or rosemary to the oil for an aromatic twist.

Instructions

Step 1: Make the Chili Oil

Start by making the chili oil. In a small saucepan, heat the olive oil over medium heat. Add the garlic and dried chili flakes, and cook for about 2-3 minutes until the garlic is golden and fragrant. Be careful not to burn the garlic. Once done, remove from heat and set aside to infuse.

Step 2: Caramelize the Onions

While the chili oil is cooling, heat a tablespoon of olive oil in a large skillet over medium-low heat. Add the sliced onions and a pinch of salt. Cook, stirring occasionally, for about 20 minutes until the onions become soft, golden brown, and jammy. The slow caramelization is key here, so be patient—these onions are worth the wait!

Step 3: Cook the Pasta

While the onions are caramelizing, cook the pasta according to package instructions. Once al dente, reserve 1 cup of pasta water before draining. This will help create a silky sauce later.

Step 4: Combine the Pasta and Onions

Once the onions are caramelized, add the garlic to the skillet with the onions and cook for an additional 1-2 minutes. Then, add the cooked pasta directly into the skillet. Toss the pasta and onions together, adding reserved pasta water as needed to create a smooth, slightly saucy consistency.

Step 5: Drizzle with Chili Oil

Finally, drizzle the homemade chili oil over the pasta and toss again, ensuring the pasta is coated with the fragrant oil. If you want an extra kick, add more chili flakes to taste.

Step 6: Serve and Enjoy

Serve the pasta hot, garnished with fresh herbs or a sprinkle of Parmesan cheese, if desired. The caramelized onions and chili oil will make every bite flavorful and satisfying.

How to Serve Caramelized Onion Pasta with Chilli Oil

With a Fresh Salad

A simple green salad with arugula, lemon, and olive oil will balance the richness of the pasta beautifully. The freshness of the greens pairs wonderfully with the deep, savory flavors of the caramelized onions.

Crusty Bread

A warm loaf of crusty bread is perfect for mopping up the extra chili oil and caramelized onion goodness. You can toast the bread with a little garlic butter for added indulgence.

Roasted Vegetables

Roasted vegetables like zucchini, bell peppers, or cherry tomatoes make a colorful and nutritious side that complements the rich pasta.

A Light Cheese Plate

Pair the pasta with a light cheese plate of fresh mozzarella or goat cheese, which will provide a creamy contrast to the spicy, savory pasta.

Additional Tips

• Adjust the Spice: You can control the level of heat in the chili oil by adjusting the amount of chili flakes. Start with a little and add more if you like it spicier.
• Make It Vegan: For a vegan version, skip the Parmesan cheese and use a plant-based pasta if desired.
• Make Ahead: The chili oil and caramelized onions can be made ahead of time and stored in the fridge for up to 3 days. Simply reheat before tossing with the pasta.
