  1. 4 stars
    The guys loved it. I made a few adaptions because of what I had or didn’t have but turned out great. They already want it again.
    I did not have chives so just omitted them. As unusual as it is in my house, I only had cheddar and parmesan cheese so I used that. I did not have the half and half but used whole milk. I figured with everything else all the fats would be fine.
    I added a little of the fried onions from the can to the casserole as well as the dip and an onion I sauted on the stove. I decided it was too neutral in color so I added some lightly steamed broccoli florets before i topped with more cheddar and frenchs fried onions on top. I did cover for 30 mins and then uncovered for a little longer so the onions would toast and cheddar melted.
