These are thin, crispy-edged beef sliders cooked on a flat-top griddle — fast to make, easy to multiply, and genuinely hard to mess up once you know the two things that matter. The Blackstone does the heavy lifting: one surface handles the patties, the buns, and cleanup is a quick scrape. If you need to feed a crowd without running multiple batches on a small pan, this is the recipe for that.
Ingredient notes
- 80/20 ground beef: Don’t swap this for leaner beef. The fat is what creates the crust and keeps the patty from drying out in the few seconds it’s on the heat. Leaner blends stick, crumble, and taste flat.
- American cheese: It melts faster and more evenly than cheddar or Swiss on a thin patty. If you want to use something else, pepper jack is the best substitute — it still melts quickly and adds a mild kick.
- Brioche slider buns: Any soft, small bun works. Potato rolls are a solid swap and hold up slightly better if the sliders sit for a few minutes before eating.
- Dill pickles: Bread-and-butter pickles will make the slider taste sweeter overall — fine if that’s your preference, but the acidity of dill pickles does more to cut through the fat.
Why this recipe works
Two things actually drive the result here. First, the smash itself: pressing the ball of beef flat immediately on contact with a screaming-hot surface maximizes how much meat touches the griddle at once, which is what produces that browned, slightly crispy crust. If you wait even 30 seconds before smashing, the exterior starts to set and you lose most of that effect. Second, cooking the buns in the residual butter and beef fat on the griddle rather than on a clean section — skip the egg in the mix, by the way, it makes the patty mushy and adds nothing to a smash-style cook — means you’re getting flavor from the fond already on the surface instead of washing it away between steps.
If something goes sideways
- Patties are sticking to the spatula when you smash: Press a square of parchment paper between the spatula and the meat ball before smashing. Peel it off right after — it releases cleanly and leaves the crust intact.
- Crust is pale and soft instead of brown: The griddle wasn’t hot enough. Give it an extra 3–4 minutes to preheat before the first batch. A drop of water should evaporate instantly on contact.
- Cheese won’t melt before the patty overcooks: Add a small splash of water to the griddle right next to the patty and cover with a dome lid or a metal bowl for 15–20 seconds. The steam finishes the melt without continuing to cook the beef.
- Sliders are greasy and falling apart: The beef balls were probably packed too loosely or too large. Keep them around 2 oz each and loosely formed — but the smash is what holds them together, not tight packing.
- Buns are burning before they toast: Move them to a cooler zone of the griddle or pull the burner under that section down to low. Brioche has sugar in it and browns faster than you expect.
Make-ahead notes
You can portion and loosely form the beef balls up to 24 hours ahead — store them on a plate covered with plastic wrap in the fridge. Don’t season them until right before cooking; salt draws out moisture and you’ll get a wetter surface that steams instead of sears. Cooked sliders don’t reheat well: the crust softens and the bun gets soggy. If you’re cooking for a crowd and need to stagger batches, keep finished sliders loosely tented with foil on a warm (200°F) sheet pan for up to 15 minutes — any longer and the texture drops off noticeably. Freezing cooked patties is possible (up to 2 months), but thaw in the fridge overnight and reheat on a hot griddle or cast iron, not a microwave, to get any crust back.
Smash Burger Sliders on the Blackstone Griddle
Ingredients
For the Burger Patty Mixture:
- 1 lb 80/20 ground beef use freshly ground beef for better flavor and texture
- 1 tsp kosher salt season to taste
- ½ tsp freshly ground black pepper
- ½ tsp garlic powder optional, for added savory depth
For Assembling:
- 4 pieces slider buns preferably brioche, toasted
- 4 slices American cheese mild cheddar or pepper jack can be substituted
- 1 small yellow onion finely diced for optional griddling
- 1 tbsp unsalted butter for toasting the buns
- 2 tbsp mayonnaise
- 2 tbsp dill pickles sliced thin
Instructions
- Preheat the Blackstone griddle to medium-high heat (about 400°F/200°C). Lightly oil the surface for a better crust.
- In a bowl, season the ground beef with salt, pepper, and garlic powder. Divide into 4 equal portions and roll into loose balls—do not pack tightly.
- Toast slider buns face-down in butter on the cooler side of the griddle. Once golden brown (about 1-2 minutes), remove and set aside.
- Place beef balls onto the griddle and press immediately with a spatula or burger press to flatten into thin patties. Hold for 10 seconds to form a crust.
- Optional: Add a spoonful of diced onion on top of each patty and press in gently. This adds a sweet-savory element as the onions griddle directly into the meat.
- Cook patties for about 2-3 minutes until the edges are crispy and juices begin to appear on top. Flip and immediately place cheese slice on the cooked side. Cook another 1-2 minutes until cheese melts.
- Assemble each Burger: Spread mayonnaise on bottom bun, add the cheesy patty, pickles, and cover with the toasted top bun. Serve hot.
Notes
- Use a burger press or heavy flat spatula to achieve that signature crispy smash crust.
- If using leaner meat, consider adding a touch of oil to the beef or surface to keep patties moist.
- Add a dash of Worcestershire sauce to the beef mixture for umami depth.

FAQ
Can I make these on a regular cast iron skillet instead of a Blackstone?
Yes, cast iron works fine for small batches. You’ll be limited to 2–3 sliders at a time, and you won’t be able to toast the buns simultaneously, so plan for a little more back-and-forth between steps.
How do I know when the patties are done — do I need a thermometer?
Ground beef needs to reach 160°F (71°C) internal temperature. At the thin size these patties cook to after smashing, they typically hit that temperature in under 2 minutes per side on a properly preheated griddle, but a quick-read thermometer is the only reliable way to confirm — don’t guess on ground beef.
Can I use frozen ground beef?
Thaw it fully in the fridge first — cooking from frozen means the outside burns before the center reaches a safe temperature. Overnight in the fridge is enough for a standard 1-pound package.
What if I don’t have a burger press or heavy spatula?
A wide, stiff metal spatula and firm hand pressure work just as well. The key is applying even, flat pressure across the whole ball at once — a small saucepan with a flat bottom also does the job in a pinch.
Can I double-stack the patties to make them more filling?
Absolutely — two smashed patties per slider is a common approach and works well. Add the second patty directly on top of the first before adding cheese, so the heat from both patties helps melt it through.
