I have loved Reuben sandwiches for as long as I can remember. The combination of all the savory flavors makes for an awesome sandwich.
These sliders are a great way to use leftover flat-cut corned beef, but I often use deli corned beef to enjoy these sandwiches all year long.
Ingredient notes
- Corned beef - Both deli-sliced and leftover corned beef can be used.
- Swiss cheese - Thin, deli-sliced cheese melts well in these sliders.
- Slider-style rolls are readily available in supermarkets these days. They typically come in packages of 12, which is needed for this recipe. Any soft slider roll - like potato, brioche, or Hawaiian rolls - works great in this recipe.
- Thousand Island dressing and sauerkraut are the classic condiments on Reubens. Store-bought dressing and canned sauerkraut add to the convenience of this dish.
- Butter and seasonings including dill, ground mustard, paprika, parsley, minced onion, coriander, and clove add flavor to the top of the rolls.

Step-by-Step Instructions
See the recipe card for complete instructions and ingredient amounts.
- Spray a baking dish with non-stick baking spray. Arrange the bottom of the rolls in the casserole. Spread the rolls with half of the Thousand Island dressing and half of the Swiss cheese.
- Add the corned beef, followed by the sauerkraut and the remaining cheese. Spread the remaining Thousand Island dressing on the inside of the tops of the rolls.
- Place the tops of the buns on top of the sliders. In a small saucepan, melt the butter and stir in the seasonings. Brush the mixture over the top of the rolls.
- Cover the casserole with aluminum foil and bake at 350℉ for 30 minutes. Uncover and bake for another 5 minutes.
Expert Tips
- Save the extra spice blend to use as a rub on meat or chicken or to season roasted vegetables.
- To reheat, cover the casserole dish with foil and reheat it in a 350℉ oven. For individual portions, wrap the sliders in a paper towel and heat them in the microwave for 30-45 seconds.
Reuben sliders are perfect for lunch or dinner, game-day snacks, or potlucks. Leftovers reheat well so this is a convenient dish for weeknight meals.
