Ingredients

Scale

Primary Ingredients

  • 2 large sweet onions (Yellow or Vidalia), thinly sliced
  • 3 tablespoons olive oil
  • 3 garlic cloves, minced
  • 12 ounces pasta (spaghetti, fettuccine, or preferred type)
  • 1/4 cup white wine or broth (optional, for deglazing)
  • 1/2 cup freshly grated Parmesan cheese
  • 2 tablespoons fresh herbs (thyme or parsley), chopped
  • Salt and freshly ground black pepper, to taste

Instructions

  1. Prepare the Onions: Thinly slice the sweet onions and heat olive oil in a wide skillet over medium-low heat. Slowly sauté the onions, stirring frequently to prevent burning, allowing their natural sugars to develop and turn golden brown. This process takes about 20-25 minutes.
  2. Add Garlic and Deglaze: Once the onions are tender and richly caramelized, add the minced garlic and cook for about 1 minute until fragrant. Then pour in a splash of white wine or broth to deglaze the pan, scraping up any flavorful browned bits from the bottom.
  3. Cook the Pasta: Bring a large pot of salted water to a boil. Cook your pasta according to package instructions until al dente. Reserve one cup of pasta water before draining to adjust the sauce consistency later.
  4. Combine Pasta and Onions: Toss the drained pasta into the skillet with the caramelized onion mixture. Stir gently while gradually adding reserved pasta water to create a silky, cohesive sauce that clings perfectly to each strand.
  5. Finish with Cheese and Herbs: Remove the skillet from heat. Sprinkle generously with freshly grated Parmesan cheese and chopped herbs. Toss briefly, then season with salt and pepper to taste. Serve warm.

Notes

  • Patience is key: Take your time caramelizing onions slowly on low heat for optimal flavor without burning.
  • Use a wide pan: A large surface area allows even cooking and easier stirring of onions.
  • Reserve pasta water: It’s rich in starch and perfect for loosening the sauce and improving texture.
  • Freshly grate cheese: Pre-grated cheese can have additives that reduce melting quality.
  • Season gradually: Add salt and pepper throughout cooking to layer flavors, avoiding over-seasoning at the end.
