Cheesy Roast Beef Sliders


Cheesy Roast Beef Sliders are the perfect recipe for a crowd. You can easily make a large batch of these sliders for a party or holiday potluck and bet that everyone will be thoroughly satisfied. Made with melted Brie, these sliders are as elegant as they are delicious. They are also super easy to make! All you need are a few ingredients and about a half hour from start to finish. If you're familiar with funeral sandwiches, this recipe is very similar. We've substituted roast beef in place of ham, and Brie in place of Swiss, but other than that, the basic recipe is the same. These sliders are the perfect thing to make for a potluck and are sure to delight!

These do look remarkably similar to the Arby's sliders they're currently offering. One of my favorites is the jalapeno roast beef, and I think when I make these, I'll add a bit of chopped jalapeno to make it close to what they serve. I know they don't use brie but some jack cheese would work well. I found a bottled horseradish sauce I really like at Aldi's, but I should try the homemade version given in this recipe.

Pretty much anything on Hawaiian rolls is amazing...and this without doubt is no exception to the rule. It's kinda like an upscale version to the traditional Arby's roast beef sandwich. (Which I happen to love) You can even make this on the bigger rolls as a meal if you wanted to and switch it up to your liking or customize each one for the picky eaters in your family.

These roast beef sliders look totally delish. I love the idea of melted Brie. That must taste really awesome. I would most definitely drizzle the butter over and top with poppy seeds. Even in small amounts poppy seeds provide iron, calcium and zinc. I cant wait to make these.

I love recipes that inspire me, and this is one of those recipes. I remember as a child going to a famous fast food restaurant for roast beef sandwiches with horseradish sauce. This recipe seems to be a great take on that sandwich. I was looking for a sandwich to serve at my Super Bowl party along with the usual Buffalo wings. This is exactly what I was looking for. I may substitute Swiss cheese for the Brie, just a personal preference.

If you need to prepare something to eat for many people at once, these Cheesy Roast Beef Sliders is very practical. You need several rolls, filled in with brie cheese, roast beef, mayonnaise, butter, caramelized onion, salt and pepper then baked until the bread turns brown. I imagine this to be a very handy recipe for mom when her son or daughter's friends come to their house. Just put this preparation in the oven and the boys and girls will have happy tummy.
