Step‑by‑Step Instructions for Caramelized Onion Pasta Recipe

Step 1: Caramelize Onions
In a large skillet, heat 2 tablespoons of olive oil and 2 tablespoons of unsalted butter over low to medium heat. Once the butter melts, add 2 medium finely sliced onions. Cook them slowly for 20-30 minutes, stirring occasionally, until they turn golden brown and develop a sweet aroma. Patience is key here; this gradual process brings out the rich flavors essential for your Caramelized Onion Pasta.

Step 2: Make Sauce
Stir in 2 tablespoons of chili oil into the caramelized onions, allowing it to meld with their sweetness. Next, pour in 500ml of heavy cream along with 1 tablespoon of garlic powder, and sprinkle in salt and pepper to taste. Let the mixture simmer gently for about 5 minutes, stirring occasionally, until it thickens slightly and the flavors combine seamlessly, creating a luxurious base for your pasta.

Step 3: Cook Pasta
Meanwhile, in a separate pot, bring salted water to a rolling boil, then add your choice of pasta. Cook according to the package instructions until al dente, usually around 8-10 minutes, stirring frequently to prevent sticking. Once cooked, drain the pasta, reserving about a cup of the starchy cooking water, which can be used to adjust the sauce consistency later.

Step 4: Combine
Add the drained pasta directly to your skillet with the creamy sauce, gently tossing to coat everything well. If the sauce seems too thick, incorporate small splashes of the reserved pasta water until you reach your desired consistency. Allow the combined mixture to simmer for another 2-3 minutes over low heat, ensuring every piece of pasta is enveloped in the rich flavors of the Caramelized Onion Pasta.

Step 5: Finish and Serve
Remove the skillet from heat and stir in 4 tablespoons of chopped fresh parsley for a burst of color and freshness. Taste and adjust seasoning with more salt or pepper as needed. Allow your irresistible Caramelized Onion Pasta to cool slightly before serving, and consider sprinkling grated Parmesan on top for an extra touch of indulgence.

Make Ahead Options

This Simple Caramelized Onion Pasta Recipe is perfect for meal prep enthusiasts looking to save time during busy weeknights! You can caramelize the onions up to 24 hours in advance; simply allow them to cool before transferring to an airtight container and refrigerating. The creamy sauce can also be prepared ahead of time and stored in the fridge for up to 3 days. When you’re ready to enjoy your pasta, reheat the sauce gently on the stovetop, adding a splash of milk or cream to maintain its luxurious consistency. Cook the pasta fresh and combine everything just before serving for that delightful, restaurant-quality experience!
