🤍 Recipe Highlights
I have summarised everything that you will come to know and love (LOVE ❤) about the recipe in the points below:
- Party food: the best thing at the party right 😉👍. These sliders are perfect for parties as they only need 1 hand to hold them, are more than 'just chips', offer a little substance and a whole lot of yum.
- Simple ingredients: you will be able to get everything you need to make these sliders from your local grocery store. They are year round available ingredients that will be easy to get your hands on.
- Easy recipe: anyone of all cooking skills and abilities will be able to make these roast beef sliders. We simply cut some bread, layer some cheese, roast beef and a sandwich spread into them and bake them till the cheese melts. It is a super easy, fun recipe that doesn't require any magic tricks. Although, you might think that there is some magic involved in the rate at which they disappear 😂.
- Sliders: I feel this point should be accompanied by a woot woot! They are such great 'fun food'.
- Taste and texture: there is the tang of the horseradish cream, the oozy melting cheese, the chewy roast beef and the soft mini buns. This combination ticks a lot of the taste and texture boxes and them some.
- Versatile: these work for brunch, a way to kick off a party, as an easy dinner recipe, an appetizer, snack food, super bowl treat or picnic food. They are very versatile, popular and lend themselves to a wide variety of serving ideas.
The photo below is to show you everything you need to make the roast beef sliders recipe. Please refer to the printable recipe card for specific ingredient measurements as well as detailed instructions.
As you can see the recipe calls for:
- Butter: surprisingly we are not using this to butter the buns! Rather, we use it to make a honey mustard glaze that we brush over the tops of the buns.
- Honey: golden and sticky it is brings the 'sweet' flavour to the glaze.
- Mustard: is such a great ingredient to use with deli meats. In this case we are using dijon mustard.
- Sesame seeds: we use these to top the buns with. They add a little extra texture to the slider.
- Horseradish cream: this is a condiment that you will find in the supermarket with the sauces and mustards. I joked with myself one day that it had a little 'nay' about it. It is a pungent unique spread that pairs exceptionally well with roast meats. Pale cream in colour with a few chunks in the texture, it is a great spread for sliders.
- Cheese: I recommend swiss cheese for this recipe. It melts very well even when baked for only a short period of time. It also has a lovely strong flavour.
- Roast beef: you can use deli roast beef or head to the fridge section at the supermarket where the sandwich meats and bacon is. It is prepped and ready to go, you will only need to make smaller roast beef slices out of it and you can see the size to aim for in the photo above.
- Buns: if you cannot see these in the bakery section of the supermarket, head to the bread aisle and check there. They are cute little mini burger buns, slider rolls or mini bread rolls.
Tasty Tip: I like to provide you with a number of substitutions and variations giving you an array of options when making my recipes. If in doubt of any of the above ingredients, or wanting alternatives, read this section (further below) before jumping into the instructions on how to make the recipe which are coming next 😉👌.
Here are the step by step instructions to make the recipe. We start by preparing the buns. You will need a serrated knife and chopping board for this initial step.

👩🍳 How to Make Roast Beef Sliders
Start by slicing each of the slider buns open. Then spread the horseradish cream on both the top and bottom of the buns.
Next place a cut slice of the swiss cheese onto the base of each bun.
Once done place 2-3 slices of roast beef on top of the cheese.
- Add another piece of swiss cheese (Photo 5)
- Close the sliders (Photo 6)
- Transfer them to a baking tray (Photo 7)
- Gather the honey mustard glaze ingredients (Photo 8)
Next place another piece of cut swiss cheese on top of each piece of the layers of roast beef.
Then close the sliders by putting the tops of the rolls.
When ready transfer the sliders to a silicon mat on a baking tray then started on making the savory butter sauce.
🧀 Mini Roast Beef Sandwiches
To begin add the butter to a heatproof bowl and melt it in the microwave on high in 20 seconds increments.
Once done add the honey, sesame seeds and mustard to the melted butter and stir till consistently combined.
- Whisk together the glaze ingredients (Photo 9)
Once you have combined the glaze, use a pastry brush to coat each of the sliders with the buttery topping. You can see this process in the photo below.
- Brush sliders with the glaze (Photo 10)
Once all of the sliders are glazed we want to put them in the oven and let them bake for 8 to 10 minutes.
This gives the cheese the chance to melt and the glaze to work its magic.

Once the sliders are cooked, you can use oven mits to remove the tray from the oven, place it onto a heat proof surface and get ready to get your party food on!
🍽 Serving Suggestions
How you want to serve these sliders will depend on what purpose you have in mind for them.
If you are having a party and they are one of the menu items, you can turn them into a platter of sliders like the photo below. Pop some potato chips on there too if you want to!
You can also have a look at all of my homemade sauces if you want to find one to suit your preferences.
Otherwise you will be pretty good to throw these melty cheese golden brown sliders on a plate add some fresh herbs for garnish and be careful to not blink cause you won't see them disappear!
👍 How to Guide
How to Store
Store leftover sliders on a plate with cling wrap or in an airtight container and place them into the fridge. They can be kept for 2 days and are best reheated before being consumed.
How to Reheat
Place leftover beef sliders onto a silicon mat and reheat in the oven for about 2-3 minutes.
You can also use the microwave on high which will take only 1 to 2 minutes.
How to Freeze
This recipe is best cooked and consumed without freezing leftovers.
As a means to be organised however, you can purchase the slider rolls and freeze them then remove and thaw when you are ready to make the recipe.
😉 Substitutions and Variations
Here are my sub ins and outs that you might be thinking about as you read the post and I will tell you if I think they will work or why they won't:
- You can use your favorite type of slider bun be it mini hawaiian rolls, dinner rolls, brioche buns or mini bread rolls.
- If you want to add onions to the sliders, you need to cook them before you add them. This is because we have a very short bake time and it is not enough to also cook onions.
- You can also add some poppy seeds to the honey mustard glaze if you wish to.
- You can use mustard in place of the horseradish as the spread for the sliders if you wish to or a thin layer of butter combined with your favorite roast beef sauce.
- Other cheeses that will work are blue cheese, mozzarella cheese, provolone cheese or cheddar cheese.
- If you want even more flavour in the glaze, add 2 teaspoon of Worcestershire sauce (I used it for the glaze in the Mini Croissant Sandwiches recipe).
💡 Tasty Tips
Here are my top tips and tricks that I want to share with you so that you master the recipe from the get go:
- Use either a mini whisk or spoon to combine the glaze ingredients until they are consistently mixed together.
- If your sliders 'slide' when you are baking them and that is the tops slide off the base, you can simply push them back together and the 2 parts will stick (because of the melted cheese).
🤓 Frequently Asked Questions
How long should sliders go in the oven?
The sliders need to be cooked for 8 to 10 minutes. This allows the cheese to melt and the glaze to work its magic.
How many sliders per person?
Aim for 1-2 sliders per person. If they are for a main dish, it is common for there to be 3 sliders offered with a side of fries.
What goes well with a roast beef sandwich?
Horseradish is great spread on a roast beef sandwich as well as a cheese such as swiss or blue cheese.
