How to Make Caramelized Onion Pasta

Step 1: Prepare the Onions

Start by peeling and slicing the onions into thin, even strips so they cook uniformly. Heat olive oil or butter in a large pan over medium-low heat, then add the onions, stirring occasionally. Let them cook slowly for about 30-40 minutes until they become deeply golden and soft, releasing their natural sweetness.

Step 2: Cook the Pasta

While the onions caramelize, bring a large pot of salted water to a boil. Cook your pasta according to the package instructions until al dente. Drain and save a cup of pasta water to adjust the sauce consistency later.

Step 3: Add Garlic and Combine

Add minced garlic to the pan with the caramelized onions, cooking gently for 1-2 minutes until fragrant. Then toss in the drained pasta, stirring well to coat every strand in the luscious onion mixture. Use reserved pasta water to loosen the mixture if needed.

Step 4: Finish with Cheese and Season

Sprinkle freshly grated Parmesan cheese over the pasta, stirring to create a creamy, flavorful coating. Season generously with salt and freshly ground black pepper, tasting as you go to make sure the balance is just right.

Step 5: Garnish and Serve

Add freshly chopped herbs like basil or thyme for a burst of freshness and serve immediately while warm and aromatic.

Pro Tips for Making Caramelized Onion Pasta

• Low and Slow Cooking: Patience is key when caramelizing onions to develop their sweetness fully without burning.
• Use a Wide Pan: A broad surface area helps onions cook evenly and reduce sogginess.
• Reserve Pasta Water: This starchy water helps bind the sauce to the pasta for a silky finish.
• Season Gradually: Add salt during cooking but adjust final seasoning at the end to avoid over-salting.
• Freshly Grate Cheese: Fresh Parmesan melts better and adds rich, mellower flavor than pre-grated options.

Reheating

Reheat gently in a pan over low heat, adding a splash of water or broth to prevent drying out, or warm briefly in the microwave, stirring occasionally for even heat distribution.
