Ingredients

  • 4 large onions
  • ⅓ cup olive oil
  • ¼ cup chopped sundried tomatoes
  • 1 Tbsp chili crisp or chili crunch
  • 1 cup heavy cream
  • ⅓ cup grated parmesan cheese
  • 1 lb linguine or buccatini, cooked al dente
  • Fresh chopped parsley
  • Salt and pepper to taste

Instructions

  1. Step 1: Cut the onions in half and remove the peel. Thinly slice all the onions lengthwise and transfer to a large pot or wide sauté pan. Pour in the olive oil and sprinkle with salt and pepper.
  2. Step 2: Set the pan over medium heat until the onions just start to sizzle. Reduce the heat to medium-low and cook, stirring every 5-7 minutes, for about 45 minutes or until the onions are deeply caramelized and reduced to about 1½ cups.
  3. Step 3: Increase the heat to medium, then add the chopped sundried tomatoes, chili crisp, and heavy cream. Bring to a simmer, then add the parmesan cheese and reduce heat back to medium-low.
  4. Step 4: Cook the cream sauce gently for about 3-4 minutes, then add the cooked pasta and toss to combine. Let cook for 1 more minute in the sauce.
  5. Step 5: Serve the pasta topped with extra parmesan cheese and fresh chopped parsley.

Tips & Variations

  • Use a wide, heavy-bottomed pan to caramelize the onions evenly without burning.
  • For a vegetarian version, ensure the parmesan is vegetarian-friendly or substitute with nutritional yeast.
  • Add toasted pine nuts or walnuts for extra texture and flavor.
  • Swap linguine or buccatini with your favorite pasta shape like fettuccine or spaghetti.
  • Adjust chili crisp amount to control the spice level.

Storage

Store leftover pasta in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove with a splash of cream or water to loosen the sauce, stirring occasionally until warmed through.

How to Serve

A white round plate holds a mound of thin spaghetti noodles mixed with a light brown sauce. The spaghetti is topped with small bits of browned ingredients and freshly ground black pepper, adding specks of dark texture throughout. The noodles appear oily and slightly glossy, twisted and piled high in the center of the plate. A woman's hand with a natural nail color gently supports the plate from below, and the whole scene sits on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7
