Caramelized Onion and Bacon Bucatini is a creamy, savory pasta dish built on deeply caramelized onions, crispy bacon, and roasted garlic simmered in a rich tomato-cream sauce. The 20–25 minute onion caramelization is the key to its complex, restaurant-quality flavor.

Preheat your oven. Slice the tops off two heads of garlic, place on a cutting board or baking sheet, season with salt and pepper, and drizzle with about 1 tablespoon of olive oil. Roast until soft and caramelized.
While the garlic roasts, prepare the other ingredients. Thinly slice the onions, chop the chives, and chop the bacon into small pieces.
In a large pan over medium heat, add the remaining 2 tablespoons of olive oil. Add the chopped bacon and cook until crispy. Remove the bacon bits with a slotted spoon, leaving the rendered fat in the pan.
Add the sliced onions to the pan with the bacon fat. Season with salt and pepper and cook slowly, stirring occasionally, until the onions are deeply caramelized and soft, about 20-25 minutes.
Pour in the chicken broth to deglaze the pan, scraping up any browned bits from the bottom.
Squeeze the roasted garlic cloves out of their skins and into the pan with the onions. Stir to break them up and incorporate them into the mixture.
Stir in the tomato paste, chili crisp, paprika, onion powder, garlic powder, and red pepper flakes. Cook for one minute until fragrant.
Reduce the heat and pour in the heavy cream. Stir until the sauce is well combined and has a creamy consistency.
Return the crispy bacon bits to the sauce and stir to combine.
Add the cooked bucatini pasta to the pan with the sauce. Toss well to coat everything evenly. Stir in the chopped chives.
Serve immediately, garnished with grated Parmesan cheese, fresh parsley, and another crack of black pepper if desired.
Refrigerate leftovers in an airtight container for up to 3 days. Reheat gently on the stovetop with a splash of cream or broth to restore creaminess.
About 20–25 minutes over medium heat, stirring occasionally. Don't rush this step; the deep color and soft texture are what make the dish special.
Yes. Prepare the sauce (through step 9) up to 1 day ahead, refrigerate, then reheat gently before tossing with fresh cooked pasta.
The recipe doesn't specify an oven temperature. Use a standard 400°F and roast for 35–45 minutes until the garlic is soft and caramelized.
Yes. Any long pasta like spaghetti, fettuccine, or linguine works well. Avoid short pasta, which won't capture the creamy sauce as effectively.
No; it contains heavy cream and Parmesan cheese. You can substitute heavy cream with coconut milk or cashew cream, but the flavor will differ.
