Ingredients
- 1 lb pasta such as fettuccine, linguine, or rigatoni
- 2 tbsp unsalted butter
- 1 tbsp olive oil
- 2 large yellow onions thinly sliced
- 1 tsp sugar optional, to speed up caramelization
- 4 cloves garlic minced
- 1.5 tsp smoked paprika
- ¼ cup dry white wine or vegetable broth for deglazing
- 4 oz cream cheese softened and cubed
- ½ cup heavy cream
- 1 cup reserved pasta water more as needed
- ½ cup grated Parmesan cheese plus more for serving
- Salt and freshly ground black pepper to taste
- 2 tbsp fresh parsley chopped, for garnish
Instructions
- Bring a large pot of heavily salted water to a boil. Add the pasta and cook according to package directions until al dente. Just before draining, reserve at least 1.5 cups of the starchy pasta water. Drain the pasta and set aside.
- While the pasta cooks, heat butter and olive oil in a large skillet or Dutch oven over medium heat. Add the thinly sliced onions, a pinch of salt, and the optional sugar. Cook, stirring occasionally, for 20-25 minutes. The onions should be deeply golden brown, soft, and jammy. Don't rush this step – it's where all the flavor develops!
- Once the onions are caramelized, add the minced garlic and smoked paprika. Stir constantly and cook for about 1 minute until fragrant, being careful not to burn the garlic.
- Pour in the white wine or vegetable broth to deglaze the pan. Scrape up all the flavorful browned bits from the bottom of the skillet with a wooden spoon. Let the liquid simmer and reduce by about half, which should take 1-2 minutes.
- Reduce the heat to low. Add the cubed cream cheese and stir until it melts completely into the onions, creating a thick base. Slowly pour in the heavy cream and 1 cup of the reserved pasta water, whisking until the sauce is smooth and creamy.
- Stir in the grated Parmesan cheese until it melts. Season the sauce generously with salt and black pepper to taste. If the sauce is too thick, add more reserved pasta water, a tablespoon at a time, until it reaches your desired consistency.
- Add the drained pasta directly to the skillet with the sauce. Toss everything together until the pasta is thoroughly coated in the creamy, smokey sauce. Serve immediately, garnished with extra Parmesan cheese and fresh chopped parsley.
Notes
Chef's Tips: For truly fast caramelization, slice your onions very thinly. A mandoline slicer works wonders if you have one. Don't overcrowd the pan, as this will steam the onions instead of browning them.
Variations: Add crispy bacon or pancetta for extra saltiness, or stir in some baby spinach at the end until wilted for added greens.
Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop with a splash of milk or water to loosen the sauce.
