What You’ll Need: Ingredients for Caramelized Onion Pasta

1 pound pasta (such as spaghetti, linguine, or fettuccine) – Choose a long strand pasta for optimal sauce cling.

¼ cup heavy cream (optional) – Adds richness and creaminess to the sauce.
¼ cup grated Parmesan cheese (optional) – Contributes a salty, nutty flavor.
1 tablespoon balsamic vinegar – Adds a touch of tanginess and complexity.

How To Make It: Step-by-Step Cooking Instructions for Caramelized Onion Pasta

Step 1: Cook the Pasta to Perfection

Begin by cooking the pasta according to package directions. Ensure you cook the pasta al dente, meaning “to the tooth” in Italian, with a slight bite. This prevents the pasta from becoming mushy when combined with the caramelized onions. Once cooked, drain the pasta, reserving about ½ cup of the pasta cooking water. This starchy water will be invaluable for adjusting the consistency of the sauce later on.

Step 2: Start Caramelizing the Onions

While the pasta is cooking, begin caramelizing the onions. Heat the olive oil in a large, heavy-bottomed skillet over medium-low heat. Add the thinly sliced onions and a pinch of salt. The salt will help draw out the moisture from the onions, kickstarting the caramelization process.

Step 3: The Key to Caramelization: Patience

This is where the magic happens, and patience is key! Cook the onions slowly over low heat, stirring occasionally, for at least 30-40 minutes, or until they are deeply golden brown and caramelized. The onions will first soften, then turn translucent, and finally develop a rich, sweet aroma and a deep brown color. Be sure to stir the onions frequently to prevent them from sticking and burning. If the onions start to dry out, add a tablespoon of water or vegetable broth to the skillet.

Step 4: Add Garlic and Deglaze

Once the onions are deeply caramelized, add the minced garlic and cook for another minute, until fragrant. Then, deglaze the skillet with the balsamic vinegar, scraping up any browned bits from the bottom of the pan. The balsamic vinegar will add a touch of tanginess and complexity to the sauce, balancing the sweetness of the caramelized onions.

Step 5: Simmer in Broth and Cream

Add the vegetable broth to the skillet and bring to a simmer. Cook for another 5 minutes, allowing the flavors to meld together. If desired, stir in the heavy cream and Parmesan cheese for a richer and creamier sauce. Season with dried thyme, salt, and pepper to taste.

Step 6: Combine the Pasta and Sauce

Add the cooked pasta to the skillet with the caramelized onion sauce and toss gently to combine, ensuring that all the pasta is evenly coated with the sauce. If the sauce is too thick, add a little of the reserved pasta cooking water to thin it out.

Step 7: Serve and Enjoy

Serve the Caramelized Onion Pasta hot, garnished with fresh parsley and any optional additions, such as roasted vegetables, toasted nuts, or crumbled goat cheese. A drizzle of olive oil can add a glossy sheen and enhance the overall flavor.
