"This is my first review. Since I had all ingredients I made w/ gruyere and no yolk noodles. (BJ's carries gruyere - much less $ than local market.) I agree with using more bacon - I used 4 strips and would make it 6-7 strips.
As to the wine - I used whatever white was opened and feel wine,
when asked for, adds to the taste. I did use flour as sauce was runny - I think 2 tablespoons, if not a bit more and the sauce did disappear in baking. Would add a little more of the liquids to make extra sauce. Oh! And I used fat free half and half, mixed with a little heavy cream. I gave this 4 stars but with a little tweaking it could become 5 stars. Would like to make with leftover roast turkey - it would be even better. I used ground turkey to which I addded 1 shredded chicken breast as I was short.
