How to Make Caramelized Onion Pasta with Chilli Oil: An Incredible Ultimate Recipe
Step 1: Caramelize the Onions
Set a large skillet over medium heat and swirl in the olive oil and butter. Once melted and shimmering, add your thinly sliced onions. Stir them often and be patient: caramelizing onions takes about 30 to 40 minutes, but the payoff is in those deeply golden, almost jammy strands with layer upon layer of savory sweetness. If they start sticking, lower the heat slightly or drizzle a splash of water in to deglaze.
Step 2: Infuse with Garlic and Chilli Oil
When the onions are dark and richly caramelized, stir in the minced garlic and let it cook for 1 to 2 minutes until fragrant — you’ll know it’s time when your kitchen smells absolutely amazing. Next, pour in the chilli oil: this is where Caramelized Onion Pasta with Chilli Oil: An Incredible Ultimate Recipe takes on its spicy, aromatic edge.
Step 3: Create the Creamy Sauce
Turn the heat down to low and add the heavy cream to your skillet, stirring as it blends with the caramelized onions, garlic, and chilli oil. Then, sprinkle in the freshly grated Parmesan and Italian seasoning. Stir until the cheese melts and everything transforms into a glossy, lush sauce.
Step 4: Cook the Pasta
Meanwhile, in a large pot of well-salted boiling water, cook your spaghetti or linguine until it’s just al dente. Before draining, scoop out about 1/2 cup of that starchy pasta cooking water — you’ll need it to bring the sauce together perfectly.
Step 5: Combine and Finish
Add the drained pasta straight to the skillet with your sauce, tossing everything together so each noodle gets coated. Splash in a little pasta water at a time until you have a silky, clinging consistency. Taste and season generously with salt and black pepper. Serve immediately, and don’t forget that extra dusting of Parmesan, a sprinkle of parsley, and another drizzle of chilli oil for dramatic flair.
