Blackstone Smash Burger Recipe: Crispy, Juicy & Easy
The smash burger was made for the flat-top. You need screaming-hot, flat steel to get those crispy, lacy edges — and the Blackstone delivers exactly that. This recipe gives you a double smash burger with a simple special sauce that beats anything from a fast food counter.
The technique is the whole game here: a cold beef ball smashed hard against a ripping hot surface, then left alone until the crust releases. Do that right and you get the perfect contrast of crispy exterior and juicy, fatty center. Do it wrong (too low a heat, not enough pressure, moved too early) and you just have a flat burger. This recipe walks you through it properly.

Ingredients
The Burgers
- 1.5 lbs 80/20 ground beef
- 1 tsp kosher salt
- ½ tsp black pepper
- 8 slices American cheese
- 4 brioche burger buns, toasted
- Avocado oil or butter for the griddle
Special Sauce
- ½ cup mayonnaise
- 2 tbsp ketchup
- 1 tbsp yellow mustard
- 1 tbsp sweet pickle relish
- 1 tsp white vinegar
- ½ tsp garlic powder
- ½ tsp onion powder
- Pinch of smoked paprika
Toppings
- Shredded iceberg lettuce
- White onion, finely diced
- Dill pickle slices
- Tomato slices (optional)
Instructions
Step 1: Make the Special Sauce
Mix all sauce ingredients in a small bowl. Refrigerate until ready to serve — it gets better as it sits.
Step 2: Portion the Beef
Divide the ground beef into 8 equal balls, roughly 3 oz each. Do not overwork the meat — just gently roll into a loose ball. Cold beef smashes better, so keep them refrigerated until the griddle is ready.
Step 3: Preheat the Blackstone
Set to high heat and preheat for 10–15 minutes. You want the surface as hot as possible — 450–500°F. Add a thin layer of avocado oil right before cooking.
Step 4: Smash
Place a beef ball on the griddle. Immediately place a piece of parchment paper over it and press down hard with a heavy spatula or burger press for 10–15 seconds. The patty should be about ¼ inch thick. Season the top with salt and pepper. Do not move it.
Step 5: Cook and Flip
Cook for 2–3 minutes until the edges are visibly crispy and brown and the patty releases cleanly. Flip once. Immediately place 2 slices of American cheese on top. Cook 1 more minute.
Step 6: Stack and Serve
Toast the brioche buns cut-side down on the griddle for 30–60 seconds. Spread special sauce on both bun halves. Stack two patties per burger, add onion, pickles, and lettuce, and serve immediately.
Tips for the Best Blackstone Smash Burger
- 80/20 beef is non-negotiable. The fat content is what gives you the crispy edges and juicy interior. Leaner beef produces a dry, sad smash burger.
- The hotter the better. Don’t rush the preheat. A hot griddle is the single biggest factor in getting crispy edges.
- Smash fast and hard. You have about 10 seconds after the ball hits the griddle before the exterior starts to set. Get the parchment on it and press immediately.
- American cheese melts best. It’s the right call here — it melts evenly over the whole patty and creates that classic diner finish.
- Cook in batches if needed. Don’t crowd the griddle. Each smash needs room or the surface temp drops too fast.
Frequently Asked Questions
What beef is best for smash burgers on a Blackstone?
80/20 ground beef (80% lean, 20% fat) is the standard for smash burgers. The fat renders against the hot griddle surface and creates the crispy, caramelized crust. Anything leaner and you lose that texture and flavor.
Do you need a burger press for smash burgers?
No — a heavy stainless spatula and some force works just as well. The key is to apply firm, even pressure for a full 10–15 seconds. A burger press just makes it easier and more consistent.
How hot should the Blackstone be for smash burgers?
As hot as it gets — ideally 450–500°F. The high heat is what causes the Maillard reaction that creates the crispy crust. Medium heat produces a steamed, grey patty instead of a seared one.
How long do smash burgers take on a Blackstone?
About 2–3 minutes on the first side, 1 minute on the second — 3–4 minutes total per batch. The whole recipe including prep takes under 20 minutes.
Can I make smash burgers ahead of time?
The sauce can be made 2–3 days ahead. The beef balls can be portioned and refrigerated for up to a day. The burgers themselves are best cooked fresh and eaten immediately — they don’t hold well.
