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
- 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.
- 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.
- 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.
- 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.
- Step 5: Serve the pasta topped with extra parmesan cheese and fresh chopped parsley.

- Swap linguine or buccatini with your favorite pasta shape like fettuccine or spaghetti.
- Adjust chili crisp amount to control the spice level.
