Here is one for all of you out on the East Coast (there aren’t any White Castle’s out here in the West). I have only had a White Castle burger once, and it was long long ago.. but I remember that it was good. I found this recipe on the Cooking With Carrie Blog and I made a few changes. These turned out so good! And what’s really great about them.. you can have them for lunch the next day– just pop them in the microwave whole for about 40-50 seconds and they taste just as good as the night before! For those of you who have always wanted to try a White Castle burger… this recipe is for you!
1 1/2 pounds hamburger
1 onion, finely chopped
1 package Lipton onion soup mix
1 tablespoon peanut butter (yes, peanut butter.. trust me)
1/2 cup milk
Sara Lee Classic Dinner Rolls (or the really soft small-sized dinner rolls from the bakery), sliced in half
Cheese slices (you can use Kraft Singles or sliced Velveeta cheese.. we used Velveeta)
In a large bowl mix (with your hands or a spoon) the hamburger, Lipton onion soup mix, peanut butter, and milk. Spread the meat mixture on a cookie sheet with a lip. Use a cup or rolling pin to roll over the meat to smooth it out.
Put it in a 350 degree oven for about 10 minutes. The meat will shrink. Take it out of the oven and put the diced onions all around the edges to flavor the meat. Place back in the oven for about 15 minutes.
Take it out of the oven. If you want onions on your sliders then spoon them onto the meat from the sides. Add your cheese slices. Put it back in the oven for 7-10 minutes (until cheese is melted). Then add the tops of your rolls (the bottom part of the rolls will just sit on the counter) and place back in the oven for about 5 more minutes. 
Take it out of the oven. Slice the meat with a pizza cutter and pick up the slider/top bun with a spatula and set it on the bottom bun.
These look delicious! What a great idea to put the meat on a cookie sheet. That makes it really easy to make. Thank you for all of the great ideas and recipes.
How did I not know about this blog before? Looks awesome!! I'm trying these tonight.
Made these tonight. Huge hit! Husband says they are better than the real thing! Thanks!
I made these for my sons 14th Birthday-he loved them & so did everyone else. They were very similar to White Castle-not quite as good, but a great substitute. I am from an area w/WC burgers-well 20 m away. My husband made many long trips there for pregnancy cravings~ I am surprised I didn't give birth to one;)
I was not sure about the peanut butter, LOVE IT. This is a keeper. Thanks for sharing..
Love it..I was not sure about the peanut butter but it works well. Thanks for sharing….:-)
I made these for my husband and he loved them! :0)
Do you have to put in the peanut butter? Nut allergy in family.
You can try it without! It might not be as creamy but ya gotta do whatcha gotta do!
Want to try these but I am allergic to peanuts. Any substitute suggestions?
I would try almond butter (if you aren’t allergic to almonds) or just leave that part out. It will still taste fine.
Just finished eating these for dinner and they were wonderful! The only change I made was using potato bread rolls instead (just personal preference). Thank you so much for this great recipe that will be joining the monthly rotation!
These are so good! My kids loved them! I am sending the left overs with my son to school lunch tomorrow. He is so excited to show them off to his friends.
