A delicious weeknight twist on the classic deli Reuben, featuring flaky golden crescent dough, savory corned beef, and tangy sauerkraut with a gooey Swiss cheese center and a gourmet caraway finish.
Heat the oven to 375 degrees F (190 degrees C). Grease an 8x8-inch baking dish, preferably a shallow one to allow better hot air circulation for crisping.
Set the sauerkraut out for a few minutes to take the chill off, which helps the filling heat more evenly during baking.
Mix the filling
In a small bowl, stir the dry sauerkraut and Thousand Island salad dressing together until the dressing evenly coats the shreds. Ensure the mixture is cohesive and not runny.
If you notice any liquid pooling at the bottom of the bowl, pause and squeeze the sauerkraut again to remove excess moisture.
Build the bottom crust and par-bake
Unroll the crescent dough and divide it in half. On a lightly floured surface, pinch the perforations of the first half closed to form a single smooth sheet.
Roll the dough sheet to a 12-inch square and nestle it into the baking dish, pressing it firmly into the corners and allowing it to climb the sides.
Repeat the perforation-pinching process with the second half of the dough, roll it into a 9-inch square, and set it aside for the top layer.
Place the baking dish in the oven and par-bake the bottom crust for 8 to 10 minutes until it is set and lightly golden.
Layer, seal, and bake
Remove the dish from the oven and lay 4 slices of Swiss cheese over the warm crust. Add the corned beef in an even layer, followed by the sauerkraut mixture.
Finish with the remaining 4 slices of Swiss cheese to encase the filling. Place the second dough sheet on top and press the edges firmly to seal against the dish.
Brush the surface with the beaten egg white. For the optional gourmet crust, brush with melted butter mixed with garlic powder and caraway seeds, then sprinkle with Everything Bagel seasoning.
Bake for 15 to 20 minutes until the top is deep golden brown and cheese bubbles at the edges. Let stand for 5 minutes before slicing into squares.
Notes
Moisture Management: Ensure the sauerkraut is squeezed until bone-dry in a clean kitchen towel. Any remaining moisture will turn to steam and make the crescent dough soggy.Par-Baking Necessity: Do not skip the 8 to 10 minute par-bake of the base dough. This step creates a sturdy foundation that stays crisp under the moist filling.Gourmet Twist: For authentic deli flavor, use caraway seeds in the topping to mimic the earthy notes of rye bread commonly found in classic Reubens.Reheating: For the best results, reheat leftovers in an air fryer at 350°F (175°C) for 3 to 5 minutes to restore the flaky texture of the crust.Nutrition information is estimated based on common ingredients and serving sizes and may vary.
