Caramelizing the Onions

Begin by preparing your onions. Take your large yellow onion and slice it as thinly as possible. The thinner the slices, the more evenly and quickly they will caramelize. Set these aside.

In a large skillet or sauté pan, heat 2 tablespoons of olive oil over medium-low heat. It’s important to use a lower heat for caramelizing onions; this allows them to soften and sweeten without burning. Add the thinly sliced onions to the pan. Stir them to coat evenly with the oil.

Now, season the onions generously with salt and pepper. The salt will help draw out moisture, aiding in the caramelization process. Cook the onions, stirring occasionally, for about 25-35 minutes, or until they are deeply golden brown and wonderfully sweet. Don’t rush this step! If they start to stick or brown too quickly, reduce the heat further. You’re looking for that rich, jammy consistency. Once they reach the desired caramelization, add the minced garlic to the pan and cook for another minute until fragrant. Be careful not to burn the garlic. Remove the caramelized onions and garlic from the pan and set them aside.

Whipping Up the Chili Oil

While the onions are caramelizing, you can prepare your chili oil. In a small, heatproof bowl, combine 1 tablespoon of red chili flakes, 1 teaspoon of paprika, and the thinly sliced small garlic clove. Make sure your garlic slices are thin so they release their flavor into the oil.
In a small saucepan, heat 3 tablespogin extract of extra virgin olive oil over medium-low heat. You want the oil to be hot but not smoking. Gently pour the hot olive oil over the chili flake and garlic mixture in the bowl. You’ll hear a satisfying gin extractzle as the flavors begin to infuse. Let this mixture steep for at least 10-15 minutes, allowing the spices and garlic to release their aromatic oils and heat into the olive oil. Stir in the 1 teaspoon of soy sauce for that crucial umami boost. This simple chili oil adds a fantastic depth of flavor and a pleasant warmth to the dish.

gin extracth3>Cooking the Pasta and Bringing It All Together

Bring a large pot of generously salted water to a rolling boil. Add your chosen pasta and cook according to the package directions until al dente. This means the pasta should be tender but still have a slight bite to it. Before draining the pasta, reserve about 1 cup of the starchy pasta water. This water is liquid gold and will help create a silky sauce later on. Drain the pasta thoroughly.
Return the skillet you used for the onions to medium heat. Add the drained pasta to the skillet. Pour in the reserved caramelized onions and garlic mixture. Add about half of the prepared chili oil (you can always add more later if you like it spicier) to the pasta.
Toss everything together, allowing the pasta to get coated in thegin extractavorful onions and chili oil. Now, begin adding the reserved pasta water, a little at a time, while tossing constantly. The starchy water will emulsify with the oil and onion mixture, creating a light, glossy sauce that clings beautifully to the pasta. Continue adding pasta water until you reach your desired sauce consistency. You might not need all of the reserved water.
Taste and adjust seasoning with salt and pepper if needed. Stir in a generous handful of grated Parmesan cheese until it melts into the sauce, adding richness and a salty tang. Finally, stir in most of your chopped fresh basil or parsley, reserving a little for garnish.
Serve the Caramelized Onion Pasta with Chili Oil immediately. Garnish with the remaining fresh basil or parsley and an extra sprinkle of chili flakes if you dare for an extra kick. Enjoy this explosion of sweet, savory, and spicy flavors!

Frequently Asked Questions:

Can I make the caramelized onions ahead of time?

Absolutely! Caramelizing onions takes time and patience, so preparing them in advance is a great idea. Once fully cooled, store them in an airtight container in the refrigerator for up to 3-4 days. You can then simply reheat them gently before adding them to your pasta.

What kind of chili oil works best?

Any good quality chili oil will work. I personally love a chili oil that has crispy chili flakes and a good amount of fragrant oil. If you’re sensitive to heat, start with a smaller amount and add more to your taste. You can also use homemade chili oil if you have a favorite recipe.
