How to Make the Ultimate Reuben Sandwich
1. Prep Your Ingredients
- Drain the sauerkraut to prevent a soggy sandwich.
- Slice the corned beef thinly if it’s not already.
- Spread Thousand Island dressing on one side of each bread slice.
2. Assemble the Sandwiches
- Lay two slices of rye bread on a clean surface.
- Add one slice of Swiss cheese to each piece.
- Pile on warm corned beef, spreading it evenly.
- Top with sauerkraut and another slice of Swiss cheese.
- Place the remaining two slices of rye bread on top, dressing side down.
3. Grill Until Golden & Melty
- Heat a large skillet or griddle over medium-low heat.
- Butter the outside of each sandwich (just like making a grilled cheese).
- Cook for 3-4 minutes per side, pressing lightly with a spatula, until the bread is golden brown and crispy, and the cheese is melted.
💡 Tip: Low and slow is key! Cooking over medium-low heat allows the cheese to melt without burning the bread.
4. Serve & Enjoy!
- Slice the sandwich diagonally for that classic deli look.
- Serve with a pickle, chips, or a side of coleslaw for the full deli experience.
