Easy Beef Brisket Sliders

These beef brisket sliders are beefy, savory, and insanely delicious. Similar to my Beef Dip Slider with Au Jus, but made with tender Montreal spiced brisket, Havarti cheese, and a buttery garlic bun. YUMM!

If this beef slider doesn’t become one of your favorites, I’ll be amazed. Get your napkins ready because you’ll want more than one or two,.. or three!

Things I Love About These Beef Brisket Sliders

Leftovers: When I make a brisket (or any beef roast for that matter), there are almost always leftovers. This slider recipe is a delicious way to use leftover brisket roast.
Flavor Combination: I love the combination of savory beefy flavors mixed with the creamy, melted cheese and mustard. The toasty bun with it all makes for a delicious and satisfying bite.
Sliders feed a crowd: Just like my Italian Sliders recipe, this slider recipe can easily feed a crowd for any event, game day, backyard party, or picnic!

Ingredients And Substitutions

• Cooked Brisket (shredded or thinly sliced): I used leftover beef 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. You can also use smoked beef brisket or even shredded roast beef if that’s what you have handy.
• 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 – 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.
• 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. You can leave the butter topping off if you choose, but expect the tops of the buns to be a little dry.
• Salt and pepper– to taste

How To Make Beef Brisket Sliders  

PREP: Preheat your oven to help ensure an even melting of your cheese when you cook your sliders. I like to line the baking dish with parchment paper so it’s easy to pull the sliders out all at once. You can line a sheet pan as well if that’s what you use, for easy cleanup.

STEP 1 – Cut The Buns – 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.

STEP 2 – Add The Toppings -Lay the cheese first and then the leftover brisket. The thicker your layer, the thicker your slider will be. Add the top layer of buns.

STEP 3 – Butter The Tops – Brush on the butter mixture over the tops of the buns.

STEP 4 – Bake The Sliders – Bake the sliders till toasted and the cheese is melted and bubbly. Remove from the oven when cooked and brush the remaining buttery mixture over the sliders before serving to keep the bun tops soft and flavorful.

Variations and Substitutions

Condiments: 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 sliders. You can replace the mustard with creamy, bitey horseradish as well. (My fave!)
Additions: Add some sliced jalapenos or banana peppers for a bit of heat and crunch.

Serving the Sliders

Place these tasty beef brisket buns on a platter with toothpicks and napkins 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 Sliders

They’ll stay great in the fridge, wrapped securely, for up to 4 days. It’s important to wrap them securely. I like to use plastic wrap to prevent any air from hardening the buns.

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.

The Second Act: How to use up leftover Beef Brisket Sliders

If you have leftovers, don’t throw them away. Repurpose these sliders by using them in a few different ways.

1. Beef Brisket Tortillas: Remove the buns and use the shredded brisket and additional cheese (if needed) to make quesadillas.
2. Beef and Havarti Stuffed Potatoes: Remove the buns and use the meat and additional cheese (if needed) to baked potatoes cut in half horizontally. Scoop out the cooked potato, mix with the beef and restuff the potato halves, and bake.
