Easy Brisket Sliders

These brisket sliders are beefy, savory, and insanely delicious. Similar to my Beef Dip Slider with Au Jus, but made with beefy Montreal spiced brisket, Havarti cheese, and a buttery garlic bun. YUMM! They’re sure to become your new favorite slider.

Reasons To Love These Sliders

Well, besides the flavor which goes without saying, they’re a super easy way to use up leftover brisket roast.
The savory, beefy flavor combined with the creamy, melted cheese and mustard makes for a delicious and satisfying bite.
Just like my Italian Sliders recipe, they can easily feed a crowd for any event, game day, backyard party, or picnic!

Groceries You’ll Need for These Beef Sliders

• Cooked brisket, shredded or thinly sliced: I used leftover brisket that I had cooked the day before, but if you don’t have any on hand, buying it from your local deli will be just as delicious.
• Slider buns – I’ve used both Hawaiian rolls and regular tray buns to make these sliders. As long as they are baked together and you can slice them horizontally, they’ll work.
• Seedy mustard – Old-fashioned seedy mustard is ideal but you can use Dijon or any type of mustard you prefer. I recommend not using honey mustard though.
• Havarti cheese – Sliced Havarti gives these sliders a creamy cheesy flavor and definitely worth every slice. Look below for other substitutions if you don’t care for Havarti.
• Butter, Garlic, and Parsley – This is for the topping that you brush on top of the buns before they go into the oven, and again after they come out. They give extra tasty flavor to each slider.
• Salt and pepper, to taste

Making These Beef Brisket Sliders  

Preheat your oven to help ensure an even melting of your cheese when you cook your sliders. 

Cut the tray buns in half horizontally, then place the bottom half of the slider buns in a baking dish and spread a thin layer of mustard.

Top each bun with cheese and then the leftover brisket. The thicker your layer, the thicker your slider will be.

Brush on the butter mixture over the tops of the buns.

Place the baking dish in the oven and bake for about 10 minutes or until the cheese is melted and bubbly.

Variations and Substitutions

Swap out the mustard for a BBQ sauce for a sweet and tangy twist on the classic. Try a spicy mustard if you would like to kick up the heat in your slides. You can totally replace the mustard with creamy horseradish as well.

Add some sliced jalapenos or banana peppers for a bit of heat and crunch.

You can use different types of cheese. I used Havarti because it melts really well and the flavor is very rich. You can use other cheeses like provolone, cheddar, or smoked gouda, to switch up the flavor profile to fit your preferences.

Serving the Sliders What Sides?

Place them on a platter with toothpicks for easy snacking or serving on a game day buffet table.

Similar to my Italian Sausage Meatball Sliders, I like to serve them with a side of coleslaw for a refreshing and crunchy addition to the savory, beefy flavor of the brisket. Dill Pickle Pasta Salad would be fantastic as well!

These of course go great with french fries or potato chips if you are looking for an easy option.
Having an assortment of sliced pickles, pickled onions, and olives is a great addition for their briny flavor that helps cut through the richness of the sliders.

Storing Leftovers

When it comes to eating the leftovers, I recommend reheating them in the air fryer, microwave, or oven in a safe baking tray.

I don’t recommend freezing them after cooking as the texture of the bread can become both hard and soggy at the same time leading to a less-than-pleasant experience.

They’ll stay great in the fridge, wrapped securely, for up to 4 days.
