Wonderful recipe. So easy! I do recommend that you slice the onions into thin slices. Wait until they caramelize before putting them on top of the biscuits. Onion/Poppy Seed flavor rocks!
So easy and quick to make! Next time I will use less onion for our taste. I also used a glass square baking dish instead of round pan. Sliced this while warm and we had a nice tasting snack.
