Corned Beef Sliders with gooey Swiss cheese, deli corned beef, homemade Russian dressing and sauerkraut even got rave reviews from the man who had declared his dislike of corned beef for decades!
Preheat the oven to 350º.
Make homemade Russian dressing by whisking together mayonnaise, ketchup, horseradish, Worcestershire and salt and pepper to taste. Set aside.
Cut slider buns in half horizontally. Place the bottom buns in an oven safe dish (I did not separate them).
Spread dressing on buns. Layer with half the corned beef, half the cheese, the sauerkraut, the rest of the corned beef and the rest of the cheese. Add the top buns.
Make the butter topping by mixing together all the ingredients. Drizzle over buns. May sprinkle with more Parmesan if desired.
Cover the buns with foil and bake for 30 minutes or until the cheese is melted and sandwiches are heated through. Remove foil and broil for just a minute if desired.
Cut into individual sliders and serve warm.
