Who knew that making a big honkin’ loaf-sized sandwich and flattening it under cement blocks, rocks, or gym weights could be so fun (or so delicious)?
I’d seen other Big Flat Sandwiches around Pinterest and other blogging circles, but when Wardee first presented the idea of making a real food Big Flat Sandwich, I immediately knew I needed to try my all-time favorite sandwich — the Reuben.
The classic Reuben is a real food sandwich teeming with cultured and fermented foods — it’s a sandwich to be celebrated, with traditional corned beef, Swiss cheese, sauerkraut, and Thousand Island dressing layered between thick slices of toasted sourdough rye bread.
I love Reuben sandwiches so much that a few years ago, I created a picnic version which carefully encloses all the delectable ingredients inside the dough for an easily portable picnic bun. Need I say more to declare my love for this classic sandwich? 🙂
After making this version of a Big Flat Sandwich, I’m definitely inclined to try other. It’s an easy way to make a big meal for a crowd, and you can serve up a hearty dish for supper without hearing complaints that you made sandwiches again.
The only caveat I’ll make for creating Big Flat Sandwiches is that they are dense! You’re packing a lot of bread, meats, and cheeses into each portion.
(That, and I wish I’d had an excuse to add bacon… I think I see a BLT Big Flat Sandwich somewhere in my upcoming menu plan!)
Classic Reuben Big Flat Sandwich
These quantities are definitely changeable. Use whatever you have and in whatever quantities you like! Just remember, the higher it’s stacked, the more likely you’ll have spillage during the squashing phase.
- 1 loaf sourdough rye (preferably dark rye)
- 2 cups Thousand Island dressing (spread approximately 3/4 cup on the loaf and save the rest for dipping)
- 4 to 6 tablespoons Dijon or honey mustard
- 1-1/2 pounds thinly sliced corned beef or beef pastrami
- 8 to 10 slices Swiss cheese
- 1 to 2 cups sauerkraut, well-drained (be sure to keep the brine for future fermenting projects!)
Serves 6 to 10.
Slice the rye loaf open horizontally (the long way). Partially scoop out the inside of each half of the loaf, then slather the mustard and the Thousand Island dressing on both the top and the bottom halves.
If you’re making your own dressing, I recommend leaving out the vinegar in order to keep the dressing as thick as possible. Keep in mind that the runnier the dressing (and the more you slather on), the more it’s either going to ooze out of the bread during the squishing stage or seep into the bread, thus making it soggy. Personally, in future loaves, I might leave the dressing out and just serve it as a dip on the table.
Add the corned beef, followed by the Swiss cheese slices, and top with the sauerkraut.
Replace the top half of the loaf and drool in anticipation. 🙂 Tightly wrap the stuffed loaf in either parchment paper or aluminum foil. If you have kitchen twine, tie it up like a package to help keep everything intact while flattening.
Place the wrapped loaf on a hard, flat surface in an cool area, then place a wide, flat board on top. Layer on several heavy items, such as cement blocks, weight-lifting weights, bricks, large books, rocks, etc. Just be careful to place the heavy objects somewhat centered over the loaf so it flattens equally across the sandwich.
The pictures below show 2 different weighting setups.
Let sit for 4 to 6 hours, then remove weights, unwrap, slice into individual portions, and serve.
