Deeeelicious! We love this style of sandwich, and this one did not disappoint! We really liked how with this recipe, you put two-thirds the butter-onion mixture in the sandwich rather than all of the mixture on the top. To mince the onion, I just put it in my small chopper and let it do the work. The oven times were spot on for me. Fifteen minutes covered and 7 minutes uncovered. Thanks whizgee, for sharing your version of this popular sandwich. It is a keeper. Read More

I have made this several times with the exception, I use dried minced onions and omit the poppy seeds. Also, I make ahead of time (at least 3 hours) and refrigerate. This allows the bread to absorb the butter which creates a caramelized bottom bun!!! Always a big hit!!! Read More

I followed the recipe for the most part, but did not use onions or poppy seeds, and made just 4 sandwiches. I used black forest ham and substituted Swiss for Havarti cheese. My husband LOVED this recipe, and described it as "restaurant-quality". This recipe would be easy to make for a larger group, and would be excellent for tailgating or potlucks. This one is a definite winner - thank you! Read More

Have made these soooo many times its ridiculous! It's an addiction I have created amongst family and friends. The only thing I do differently is use way less butter and used dried chopped onion and what really makes it is.....I use a peach or peach-mango preserve on the bottom bun for a sauce and once you heat it OMG....magical party in your mouth lol Read More

Made it for lunch today. I have a house filled with picky eaters and everyone ate at least one or more. :) Did make a few substitutions based on what we had on hand. I used 1/2 tsp celery seed instead of poppy seeds, and onion powder rather than real onion. Also, turkey and provolone rather than ham and swiss. Okay, so I changed a lot since I didn't want to run to the store, but the recipe still turned out great! Read More

The only change I made was using reconstituted dried minced onion. These things are addictive! I've made these several times. If you separate your rolls rather than leaving them hooked together they turn out better - at least mine did! Don't skip the step of spreading some of the butter mixture on the rolls before piling on the ham and swiss! There is nothing healthy about these sandwiches so don't even go there. Just enjoy!

Very good, but a little too much butter. I used sesame seeds instead of the poppy seeds. I, too, like the idea of putting the sauce inside the bread and on top too. I used 2/3's of a loaf of french bread for the bread and they turned out very tasty, except for too much butter. I'd make this again for sure! Read More
