For an even richer flavor, consider using brown butter instead of regular melted butter. Brown butter will add a nutty depth to the sauce. If you don't have Chardonnay, a dry Sauvignon Blanc or Pinot Grigio can be substituted. You can also use chicken broth in a pinch, but it will alter the flavor profile slightly. Freshly grated Parmesan cheese is highly recommended for the best flavor and texture. A sprinkle of fresh parsley or chives can add a pop of color and freshness to the finished dish.

Follow The Directions
01
StepIn a large saucepan or Dutch oven, melt butter with olive oil over low heat. Add the sliced onions, minced garlic, sugar, and salt. (2 minutes)
02
StepCover the pan and cook, stirring occasionally, until the onions are very soft, translucent, and just beginning to caramelize. This process is key for developing the sauce's sweetness, so be patient and don't rush it. (20 minutes)
03
StepMeanwhile, bring a large pot of lightly salted water to a rolling boil. Add the spaghetti and cook according to package directions, until al dente. Reserve about 1 cup of pasta water before draining. (7 minutes)
04
StepPour the Chardonnay into the onion mixture. Increase the heat to medium and bring to a simmer, scraping up any browned bits from the bottom of the pan. Allow the wine to reduce by about half, concentrating its flavor. (3 minutes)
05
StepReduce the heat to low. Stir in the heavy cream and simmer gently, allowing the sauce to thicken slightly. Taste and adjust seasoning as needed. (2 minutes)
06
StepAdd the drained spaghetti to the sauce. Toss to coat thoroughly. If the sauce is too thick, add a little of the reserved pasta water until it reaches your desired consistency. (2 minutes)
07
StepServe immediately, garnished with freshly grated Parmesan cheese and a generous grind of black pepper.
