A holiday staple in many households, creamed onions are usually bathed in a rich white sauce made with heavy cream. In this version, we roast the onions for an added layer of flavor and lighten up the sauce with low-fat milk. The result is a luxuriously silky sauce with a sweet roasted onion flavor for far fewer calories and less fat. We like the smaller size of pearl onions, but boiling onions also work well.
I agreee... I used 1 lg sweet onion, slivered. I skipped the thyme and lemon juice and also added some red-fat Parm to the sauce. It was a tad too runny without it. Otherwise, these were for my dad, and he loved them!!!
