How to Make Caramelized Onion Pasta with Chilli Oil

Step 1: Cook the Pasta

Start by bringing a large pot of salted water to a boil. Add your chosen pasta and cook according to package instructions until al dente. Remember, perfectly cooked pasta will hold up beautifully against those caramelized onions.

Step 2: Prepare the Caramelized Onions

In a large skillet, heat olive oil and butter over medium-low heat. Add the thinly sliced onions along with a pinch of salt. Stir occasionally; this helps ensure even cooking. If you’re using sugar, sprinkle it over the onions now—it aids in achieving that deep golden-brown color we love. Allow them to cook for about 25-30 minutes until they are beautifully caramelized. The longer they cook, the sweeter they become!

Step 3: Make the Chili Oil

While your onions are cooking, prepare the chili oil. In a small saucepan, combine olive oil, chili flakes, minced garlic, smoked paprika (if using), and salt. Heat gently over low heat for about 5 minutes to infuse all those flavors together—it’s aromatic and adds such depth to your dish!

Step 4: Combine Everything

Once your pasta is done cooking and drained (don’t forget to save some pasta water!), toss it into the skillet with your caramelized onions. Drizzle over that lovely chili oil and mix everything well! If it seems dry, add a splash of reserved pasta water until you reach your desired consistency.

Step 5: Serve It Up

Plate up your delicious Caramelized Onion Pasta with Chilli Oil and sprinkle over fresh parsley if desired. A little extra chili oil or grated cheese can take it over the top! Enjoy every single bite—you’ve earned it!

Pro Tips for Making Caramelized Onion Pasta with Chilli Oil

Creating the perfect Caramelized Onion Pasta with Chilli Oil is all about patience and technique. Here are some pro tips to ensure your dish comes out beautifully every time!

• Choose the right onions: Yellow or sweet onions work best for caramelizing because they become sweeter as they cook, enhancing the flavor of your pasta.
• Low and slow is key: Cooking your onions on medium-low heat allows the natural sugars to caramelize without burning, resulting in a rich, deep flavor that pairs perfectly with pasta.
• Taste as you go: Adjusting salt and pepper during cooking ensures your flavors are balanced. Remember, it’s easier to add than to take away!
• Customize your spice level: Feel free to adjust the amount of chili flakes in the chili oil. Start with less if you’re unsure, as you can always add more to achieve your desired spice level.
• Leftovers make great meals: This dish keeps well in the fridge for a couple of days, making it a fantastic option for meal prep or quick lunches throughout the week!
