National Fast Food Day | Copycat Krystal Burgers – The Foodie Patootie

National Fast Food Day | Copycat Krystal Burgers

Welcome to National Fast Food Day! It’s been a very long time since I’ve had fast food, but I certainly don’t mind enjoying some of the homemade variety. I think White Castle burgers are more popular; they are packaged in the freezer section of your local grocery store, there is a whole movie centered around them, but here in Tampa, Krystal Burgers reign supreme. And anyway, they are basically the same thing.

The only thing I would change about Krystal/White Castle burgers would be to make them a little bigger. ‘Cause bite-size foods are usually so cute and awesome and make you want to eat more of them (both a good and bad thing), but come on now. Delicious greasy burgers deserve to be bigger than palm-size.

In my opinion, the best condiment on burgers is mustard so feel free to add that, or whatever else you feel like. These are homemade Krystal/White Castle burgers and you need to go with it. Enjoy!

Copycat Krystal Burgers

Ingredients:

  • 1 lb ground beef
  • 1 package dry onion soup mix
  • 1 Tbsp creamy peanut butter
  • 1/2 cup whole milk
  • 1/2 white onion, finely chopped
  • Hawaiian sandwich rolls, tops separated from bottoms
  • Sliced cheddar cheese
  • Condiments, as desired

Directions:

  1. Preheat the oven to 350*F. In a large bowl, combine ground beef, soup mix, peanut butter, and milk.
  2. On a baking sheet, spread out the hamburger mixture in an even layer, about 1/2 inch thick. Put diced onions all around the edges. Bake for 25 minutes.
  3. Remove from oven, spoon onions from edges onto meat, top with cheese slices. Bake until cheese is melted, about 5-7 minutes. Add the tops of the rolls and bake another 5 minutes.
  4. Remove burgers from oven, put any additional condiments or toppings on the bottom of the rolls, cut the burgers into squares underneath the top rolls and pair with bottom half.

      Every once in a while, I think about that tweet you sent me from someone who was pretty angry at Krystal burger haha.

    I’ll take a bag of 20 to go, mmm okay?
    ps- White castle>>>>> Krystal Burgers , but I think you have to be a Northerner to understand that 😛

      LOL I guess so because I love me some Krystal burgers!

    I recently figured out on my own that Krystal burgers tasted like White Castle. Maybe it took me so long because, in SoCal, White Castles are bought frozen, and in Florida, just go to the nearest Krystal Burger and get them fresh…then go home and freeze them. It’s the first place I went after being gone for almost 12 years. I was told there’s a secret ingredient in White Castle’s burgers and that it’s baby food.

    • Jennifer — June 25th, 2015 @ 7:12 pm

      Yes, Krystal Burger! I’ve never actually eaten at a White Castle – I’ve only had the frozen ones. That’s so interesting about the baby food, I had no idea!

    Peanut butter is really the secret ingredient??

    • Jennifer — August 29th, 2015 @ 8:19 am

      Yes! If you can believe it.

  5. Jen — August 15, 2016 at 8:13 pm

    You can use the beef baby food instead of peanut butter and they are very similar. My mom use to make them all the time.  It’s funny because I didn’t know you could use peanut butter instead of baby food lol Thanks for the recipe!

    • Jennifer — August 16th, 2016 @ 10:17 am

      Oh my gosh, that is great!! For both peanut butter AND the beef baby food, I wonder how people came to realize that would all work together, haha.

    I’m sorry but this doesn’t sound like Krystal burgers at all…Peanut butter? Soup mix? Beef mixture in the oven? The Krystal restaurants I’ve been to don’t serve their meat “sloppy joe” style, it’s patties, and they’re grilled on a flat top. They don’t all have cheese, and they are not served on sweet Hawaiian rolls. There is no way in h*** this tastes like Krystal burgers. I’m sorry to harsh your recipe, I don’t usually leave comments like this but this just looks insane to me.

    • Jennifer — January 6th, 2017 @ 1:18 pm

      I certainly appreciate your comments anyway! I take great pride in testing my recipes multiple times before putting it out there to my audience to try. I actually got inspiration for the peanut butter (which I thought was completely insane too!) from another source and I figured I might as well try it…and it worked! Don’t knock it ’til you’ve tried it is what “they” say, right? The Hawaiian rolls may not be what krystal actually uses, but that was my take because Hawaiian rolls are damn delicious. I don’t anticipate you trying this recipe based on your comment, which is totally fine!, but I still stand behind that it’s a copycat recipe, and extremely similar. Have a great day!

    Hey Jennifer! Thanks for being such a good sport. I appreciate that. 🙂 This is directly from Krystal corp in regard to the ingredients in their hamburgers, I’ll list the most important part first: Krystal Beef Patty: 100% USDA BEEF, SEASONING [ENCAPSULATED SALT (SALT, PARTIALLY HYDROGENATED SOYBEAN OIL), PEPPER].

    That’s it. The beef is lean and they use soybean oil on the flat top and season the patty with salt and pepper, but here is the complete ingredient list for a double cheese Krystal burger:
    Krystal Bun: UNBLEACHED ENRICHED WHEAT FLOUR [FLOUR, MALTED BARLEY FLOUR, NIACIN, REDUCED IRON, THIAMIN MONONITRATE (VITAMIN B1), RIBOFLAVIN (VITAMIN B2), FOLIC ACID (A B VITAMIN)], WATER, HIGH FRUCTOSE CORN SYRUP, YEAST, SOYBEAN OIL, CONTAINS 2% OR LESS OF EACH OF THE FOLLOWING: WHEAT GLUTEN, SALT, DOUGH CONDITIONERS (SODIUM STEAROYL LACTYLATE, CALCIUM STEAROYL-2-LACTYLATE, MONOGLYCERIDES, CALCIUM PEROXIDE, ETHOXYLATED MONOGLYCERIDES), SOY FLOUR, CALCIUM SULFATE, CALCIUM PROPIONATE (TO RETARD SPOILAGE), MONOCALCIUM PHOSPHATE, YEAST FOOD (AMMONIUM SULFATE). Krystal Beef Patty: 100% USDA BEEF, SEASONING [ENCAPSULATED SALT (SALT, PARTIALLY HYDROGENATED SOYBEAN OIL), PEPPER]. Cheese Slice: AMERICAN CHEESE (CULTURED MILK, SALT, ENZYMES, ARTIFICIAL COLOR), WATER, CREAM, SODIUM CITRATE, SALT, ARTIFICIAL COLOR, SORBIC ACID (PRESERVATIVE), SODIUM PHOSPHATE, ACETIC ACID, LECITHIN. Mustard: DISTILLED WHITE VINEGAR, WATER, MUSTARD SEED, MUSTARD BRAN, SALT, TURMERIC, CARAMEL COLORING, PAPRIKA, MUSTARD OIL. Chopped Onions: DEHYDRATED ONIONS. Dill Pickle Chip: CUCUMBERS, WATER, VINEGAR, SALT, CALCIUM CHLORIDE, ALUM, NATURAL FLAVORS, POTASSIUM SORBATE (PRESERVATIVE), POLYSORBATE 80, TURMERIC.

    Lots more chemicals and whatnot than I care for but, clearly, a much healthier, simpler version can be made at home. No milk, no peanut butter, no soup mix, and no loose beef.

    Thanks again for your awesome response to criticism. I apologize if my comment came across as rude, but I still stand by my statement that your recipe, though it may actually be tasty, is no Krystal burger substitute. 🙂
