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

Instructions

  1. Step 1: Cut the onions in half and remove the peel, then thinly slice all the onions lengthwise. Transfer them 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 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 1 ½ cups.
  3. Step 3: Increase the heat to medium. Add the chopped sundried tomatoes, chili crisp, and heavy cream to the pan. Bring to a simmer, then stir in the parmesan cheese and reduce heat back to medium-low.
  4. Step 4: Cook the cream sauce gently for 3-4 minutes, then add the cooked pasta and toss to combine. Let the pasta cook in the sauce for another minute, then serve with extra parmesan cheese and fresh parsley.

Tips & Variations

  • For a milder heat, reduce the amount of chili crisp or use a mild chili paste instead.
  • Add a splash of white wine when simmering the cream sauce for extra depth of flavor.
  • Use gluten-free pasta if you prefer to make this dish gluten-free.
  • Fresh thyme or rosemary can be added with the onions for an herbal note.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a pan over low heat, adding a splash of cream or water if the sauce has thickened too much.

How to Serve

A white speckled plate holds a single layer of creamy pasta mixed with caramelized onions, creating a light brown sauce that covers the noodles. The pasta is topped with fresh green parsley pieces scattered across and lightly sprinkled with grated white cheese and black pepper. The edges of the plate have some natural spots and the entire setup sits on a white marbled surface, with part of a white cup visible in the top right corner. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make caramelized onions ahead of time?

Yes, caramelized onions can be made a day or two in advance and stored in the refrigerator. This makes the cooking process quicker when you’re ready to prepare the pasta.

What is the difference between chili crisp and chili crunch?

Both chili crisp and chili crunch are spicy chili-infused oils with crunchy bits, but chili crisp usually has a more balanced flavor with garlic and sometimes fermented notes, while chili crunch is often spicier and more straightforward in heat. Use whichever you prefer or have on hand.

Other Ingredients

  • 1 Tbsp chili crisp or chili crunch
  • ⅓ cup grated parmesan cheese
  • 1 lb linguine or buccatini, cooked al dente
  • Salt and pepper, to taste

Instructions

  1. Prepare the onions: Cut the onions in half and peel them. Thinly slice all the onions lengthwise and transfer them to a large pot or wide sauté pan. Pour in the ⅓ cup of olive oil and season with salt and pepper.
  2. Caramelize the onions: Set the pan over medium heat until the onions just start to sizzle. Reduce the heat to medium-low and cook, stirring every 5 to 7 minutes, for about 45 minutes or until the onions are deeply caramelized and reduced to about 1 ½ cups in volume.

  5. Toss pasta in sauce: Add the cooked linguine or buccatini to the pan and toss well to combine the pasta with the creamy onion sauce. Let it cook together for 1 more minute so the pasta absorbs the flavors.
  6. Serve and garnish: Plate the pasta and garnish with extra parmesan cheese and fresh chopped parsley for a fresh finish.

Notes

  • Cook the onions low and slow to develop a deep, rich caramelization without burning.
  • Use good quality olive oil and parmesan cheese for the best flavor.
  • Chili crisp adds a subtle spice and crunch; substitute with chili flakes if unavailable.
  • Reserve some pasta water before draining to adjust sauce consistency if needed.
  • This dish is best served immediately but can be reheated gently with a splash of cream or water.
