Ingredients
Method
Cooking the Onions
- In a large skillet, heat butter and oil over medium heat. Add the onions and cook on medium-low, stirring occasionally, until deep and caramelized. If they start to stick to the pan, add a splash of water.
Cooking the Pasta
- Cook the pasta according to package instructions. Drain when finished, reserving ¼ cup of pasta water for later use.
Finishing the Sauce
- Once the onions are fully caramelized, add the garlic, seasonings, chili crisp, and soy sauce. Cook for another 1-2 minutes until garlic is fragrant.
- Stir in the heavy cream and return to a gentle simmer until slightly thickened.
- Remove from heat and add grated Parmesan cheese. Stir in the cooked pasta to coat, adding reserved pasta water to thin if needed.
- Top with additional chili crisp before serving if desired.
Notes
Patience is key for caramelizing onions; aim for 30-40 minutes over medium-low heat for the best flavor. Taste and adjust salt after adding cheese, as Parmesan adds salinity.
