A rich, savory pasta where deeply caramelized onions, smoky bacon, and a creamy chile crisp sauce come together to coat bucatini in bold, irresistible flavor.

Ingredients (Serves 3–4)

• 
  

  250–300 g bucatini (or spaghetti)

  
  


• 
  

  2 large onions, thinly sliced

  
  


• 
  

  4–5 strips bacon, chopped

  
  


• 
  

  2 tablespoons olive oil

  
  


• 
  

  2 tablespoons butter

  
  


• 
  

  2–3 tablespoons chile crisp (adjust to taste)

  
  


• 
  

  1/2 cup heavy cream

  
  


• 
  

  1/4 cup grated Parmesan cheese

  
  


• 
  

  2 cloves garlic, minced

  
  


• 
  

  Salt and black pepper to taste

  
  


• 
  

  1/2 teaspoon sugar (optional, helps caramelization)

  
  


• 
  

  Pasta water (as needed)

  
  

Instructions

1. 
   

   Caramelize the onions
   Heat olive oil and butter in a large pan over medium-low heat. Add sliced onions and cook slowly, stirring occasionally, for 20–25 minutes until soft, golden, and jammy. Add a pinch of salt and sugar to enhance caramelization.

   
   


2. 
   

   Cook the bacon
   In the same pan (or separately), cook chopped bacon until crispy. Remove and set aside, leaving some fat in the pan for extra flavor.

   
   


3. 
   

   Boil the pasta
   Cook bucatini in salted boiling water according to package instructions until al dente. Reserve about 1 cup of pasta water before draining.

   
   


4. 
   

   Build the sauce
   Add garlic to the onion mixture and sauté briefly. Stir in chile crisp and cook for a minute to release its aroma. Pour in heavy cream and mix well.

   
   


5. 
   

   Combine everything
   Add the cooked pasta directly into the sauce. Toss well, adding a splash of reserved pasta water to loosen and coat the pasta evenly.

   
   


6. 
   

   Finish the dish
   Stir in Parmesan cheese and crispy bacon. Season with black pepper and adjust salt if needed.
