As a huge fan of White Castle hamburgers, I had been buying the frozen kind when living in places that don't have them -- like the West Coast and in Texas. Thankfully, I found this simple and easy recipe so I can make 'em up in advance and have 'em whenever I want.
- Lay beef across a sheet of parchment paper. Top with the second sheet of parchment paper.
- Roll out beef about ¼-inch thick into 7-10 inch rectangle.
- Trim meat edges and use scraps to pat into a rectangle patty.
- Season meat generously with salt and pepper. Cut six 3-by-3-inch patties into the square using a spatula.
- Poke 5 holes in each patty with a straw in each corner and center.
- Melt butter in 12 inch skillet. Add diced onion, sauté for 1-2 minutes.
- Turn heat to medium-low. Top bed of onions with patties, 4 or more at a time, seasoning side down.
- Cover and cook patties around 4 minutes, until cooked through and no longer pink.
- Dampen kitchen towel and wrap 6 buns. Place in microwave for 10-15 seconds to steam. Add thin slice of American cheese or Velveeta if desired.
- Assemble burgers with 1 tablespoon of cooked onions on bun. Top with pickle slice and Serve with condiments as desired.
- Alternatively, omit step 9 and assemble burgers with onion only. Wrap each burger in plastic wrap or small storage bag. Place in larger double wrapped plastic storage bags and store in freezer.
- When ready to eat, remove burger from plastic wrap, add cheese if desired and microwave for 10-15 seconds. Add pickle to the burger at the end and serve with condiments as desired.
