Ingredients:

12 oz pasta (spaghetti, penne, or linguine recommended)
2 tablespoons olive oil (for sautéing)
1 large yellow onion, thinly sliced
3 cloves garlic, minced
Salt and pepper, to taste
3 tablespoons extra virgin extract olive oil (for chili oil)
1 tablespoon red chili flakes
1 teaspoon paprika
1 small garlic clove, thinly sliced
1 teaspoon soy sauce
Grated Parmesan cheese, for serving

Caramelizing the Onions

Step 1: Prepare the Onions and Garlic

Start by thinly slicing your large yellow onion. The thinner the slices, the more evenly and quickly they will caramelize. Aim for slices that are about 1/8 inch thick. Mince your 3 cloves of garlic. Set these aside for now.

Step 2: Sauté the Onions

Heat 2 tablespoons of olive oil in a large skillet or Dutch oven over medium heat. Add the thinly sliced yellow onion. You want to cook these gently, stirring occasionally, until they start to soften and become translucent, which usually takes about 5-7 minutes. Don’t rush this process; patience is key to good caramelization. Once softened, season generously with salt and pepper. The salt will help draw out moisture and encourage browning.

Step 3: Slow and Low Caramelization

Reduce the heat to low. This is where the magic happens. Continue to cook the onions, stirring every 5-10 minutes, allowing them to slowly turn golden brown and then a deep, rich caramel color. This process can take anywhere from 30 to 45 minutes, or even longer, depending on your stove and pan. You’re looking for a deep, sweet flavor and a jam-like consistency. As the onions cook down, they will shrink considerably. If they start to stick too much to the bottom of the pan, you can add a tablespoon of water or broth to deglaze and loosen them up. In the last 5 minutes of caramelization, add the minced garlic and cook until fragrant, being careful not to burn it.

Making the Chili Oil

Step 4: Infuse the Chili Oil

While your onions are diligently caramelizing, it’s time to make the chili oil. In a small saucepan, combine 3 tablespoons of egin extracta virgin olive oil, 1 tablespoon of red chili flakes, 1 teaspoon of paprika, and the thinly sliced small garlic clove. Heat this mixture over very low heat. The goal here is to gently infuse the oil with the flavors of the chili and garlic without burning them. You should see small bubbles gently rising, but you don’t want a vigorous fry. Let it simmer very gently for about 5-7 minutes, stirring occasionally. This allows the flavors to meld beautifully. After the infusion period, stir in 1 teaspoon of soy sauce. This adds a wonderful layer of umami. Remove the saucepan from the heat and let the chili oil steep while the onions finish.

Assembling the Pasta

Step 5: Cook the Pasta and Combine

Bring a large pot of generously salted water to a rolling boil. Add your 12 oz of pasta and cook according to package directions until al dente. While the pasta is cooking, make sure your caramelized onions are ready and your chili oil is fragrant. Once the pasta is cooked, drain it, reserving about half a cup of the pasta water. Add the drained pasta directly to the skillet with the caramelized onions. Pour the infused chili oil over the pasta and onions. Toss everything together well, using tongs to ensure every strand of pasta is coated. If the pasta seems a little dry, add a splash of the reserved pasta water, a tablespoon at a time, until you achieve your desired consistency. The starchy water will help create a luscious sauce that clings to the pasta.

Step 6: Finishing Touches and Serving

Serve the Caramelized Onion Pasta with Chili Oil immediately. Garnish generously with grated Parmesan cheese. The salty, nutty cheese is the perfect counterpoint to the sweet onions and spicy oil. Sprinkle with fresh chopped basil or parsley for a bright, herbaceous finish. If you enjoy an extra kick, feel free to add a sprinkle of extra chili flakes over the top. This dish is a beautiful balance of sweet, savory, and spicy, and the textures are wonderful. Enjoy every delicious bite!
