Sure. But you must change a couple of steps. Cornstarch & flour are thickeners. Flour is added to melted shortening. Cornstarch must be added to a liquid to dissolve. So, I'd melt the butter, saute the onions, then add the cornstarch mixture (2T.cornstarch to 1/4 c. water or broth blended well).....cook slightly until thickened, then add the remaining ingredients. I'm sure it'll be just fine.
