While the spaghetti cooks, melt the unsalted butter and olive oil in a large skillet or Dutch oven over medium-low heat. Add the thinly sliced yellow onions and cook, stirring occasionally, for 30 to 40 minutes, or until the onions are deeply caramelized and browned. This process requires patience to achieve the desired sweetness and color.

Stir in the chili crisp. Pour in the heavy cream and bring to a gentle simmer. Reduce the heat to low and stir in the 1/2 cup of grated Parmesan cheese until melted and the sauce is smooth and creamy. If the sauce is too thick, add a splash of the reserved pasta water to reach your desired consistency.

Add the cooked and drained spaghetti directly into the skillet with the sauce. Toss thoroughly with tongs until every strand is coated in the rich, creamy sauce. If needed, add a little more reserved pasta water to loosen the sauce.
