Baked Cheddar Roast Beef Sliders makes delicious weeknight dinner, game day grub, or party appetizer. Layers of roast beef, onions, and cheese are topped with a creamy horseradish sauce and buttery buns.
I always related tailgating and game-watching parties with sliders until I made this post. While experimenting with these Baked Cheddar Roast Beef Sliders, I realized sliders are perfect for busy weekday dinners. Sliders are also a good way to use leftover Slow Cooker Roast. Or, I’m I the only one that has leftover pot roast? Maybe I get roasts that are too big…🤔
Baked Cheddar Roast Beef Sliders is basically an ‘assembly only’ recipe. That is if you don’t cook your ribeye roast. I purchased deli-sliced roast beef which made this meal mega quick and easy.
Baked Cheddar Roast Beef Sliders Tips
- I used deli-sliced roast beef for a shortcut, but you can use any kind of beef steak for this sandwich.
- Most sliders have a buttery mixture that is poured over the top of the buns. However, I really dislike how sloppy this makes them to eat. Therefore, I pour a Worcestershire and butter mixture over the roast beef. This keeps the meat moist and the bun from being messy.
- I choose a buttery Hawaiian roll, the kind you have to pull apart, for my buns. However, you can use any bun that you choose.
- Another option, add a fried egg to your sandwich. This makes a hearty brunch sandwich.
- Roast beef and sautéed onion go together like peanut butter and jelly, in my opinion. Of course, if you don’t like onions, leave them off. Actually, I caramelize my onions instead of just getting them soft. Caramelizing them brings out their natural sweetness and pairs beautifully with beef, cheese, and horseradish sauce.
- Speaking of horseradish sauce, instead of mixing just mayo and horseradish, I also added lemon juice and Worcestershire sauce. This combination really kicks up the flavor.
- I find some cheese to be salty. I recommend salting your sandwich with a light hand. You can always add later.
