Sweet Onion Mac and Cheese Yes, a thousand times yes. The base of the dish is soubise, or onion sauce, made using the classic French technique of caramelizing sweet onions and blending them into a smooth purée. The addition of three cheeses and whole milk creates a smooth sauce for orecchiette. Crisp, flash-fried shallots are sprinkled on top of the dish before it's served, which ensures an addictive crunch in each bite.
