To make these, we’re taking a batch of tanghzong dinner rolls, filling them with thinly sliced roast beef, plenty of cheese & a punchy horseradish mayo. We’re then pouring over a mustard butter sauce, sprinkling with poppy seeds then baking until the cheese is melted & gooey. Super easy stuff!

Components Of These Sliders
Dinner Rolls
Homemade dinner rolls (or Hawaiian rolls) make the best sliders, I used my tangzhong dinner rolls! Make sure to keep the rolls attached as a whole slab, which will make it easier to slice & assemble the sliders. Ready made rolls from a bakery/supermarket will also work, you’ll need 12.
Roast Beef
These sliders are a great way to use up leftover roast beef! I used leftovers from when I made my slow roasted sirloin of beef but any cut will work. Make sure to slice it nice & thin! I also like to remove some of the excess fat but that’s optional.
Cheese
We’re using 2 types of cheese for these sliders; nutty Emmental & sharp, mature cheddar. I used a mix of sliced & grated cheese but feel free to use just one type. You can also use different types of cheese if you’d prefer. Swiss cheese, Gouda & Gruyere will all work well.
Horseradish Mayonnaise
Roast beef & horseradish are a classic combination! For our sliders, we’re using ready made horseradish sauce (Colman’s is good!) mixed with mayo & plenty of salt and pepper. This tones down the heat from the horseradish whilst still providing plenty of flavour. Feel free to add more horseradish though, if you’d like your mayo to have more of a kick.
Mustard Butter
Classic slider almost always have a butter sauce poured over them before they are baked, which is what we’re going to be doing for ours!
To make our mustard butter, we place butter into a pan, along with Dijon mustard, Worcestershire sauce, garlic powder, salt & pepper. We then melt this over a low heat before pouring it over our assembled sliders. If you’d prefer your mustard butter to have more heat, use English mustard instead of Dijon.
Poppy Seeds
Another classic slider component! We’re sprinkling a generous amount of poppy seeds on top of our sliders before baking which gives them some extra crunch & a subtle nutty flavour. Feel free to leave these out if you’d prefer or you could use sesame or nigella seeds instead.
Frequently Asked Questions
To make the best sliders, I’d recommend using homemade dinner rolls or Hawaiian rolls. Ready made rolls from a supermarket/bakery will work as well.
Leftover roast beef sliders should be stored in the fridge & eaten within a day or two. You can serve the sliders cold or reheat them in the oven, covered in foil.
Roast beef sliders can be prepared in advance & stored in the fridge for 1-2 days. To prepare the sliders in advance, assemble them but don’t pour over the mustard butter until just before you cook them.
I like to serve my roast beef sliders with red wine gravy, as I tend to make sliders the day after making a roast dinner (with leftover beef & gravy). Gravy granules dissolved in water will work as well though.
