Smash Burger Sliders

Recipe Note

Recipe FAQ

Why use brisket blend beef instead of regular ground beef for smash burgers?

Brisket blend beef has a higher fat content and a deeper, more complex flavor than standard 80/20 ground beef. That extra fat matters specifically in smash burgers — when the ball of beef hits a screaming hot griddle and gets pressed flat, the fat renders rapidly and drives the Maillard reaction that creates the crispy, lacy edge crust. Leaner beef produces a drier, less flavorful patty at this thinness. If Creekstone Farms brisket blend isn't available, an 80/20 ground chuck is the closest substitute.

Why put the onions on top of the beef before smashing instead of cooking them separately?

Placing thin-sliced onions on top of the beef ball before smashing embeds them directly into the patty as it flattens. When you flip, those onions hit the hot griddle surface and caramelize in the beef fat — they become part of the crust rather than a separate topping. It's the same technique behind Oklahoma-style onion burgers, and it's what gives these sliders their savory, deeply flavored surface beyond what the rub alone provides.

Why keep the grill lid open during the cook?

Keeping the lid open maintains true direct-heat grilling conditions at 450°F. Closing the lid on a pellet grill at high heat turns it into a convection oven — the circulating hot air steams the patties from above rather than searing them from below. For smash burgers, you want all the heat driving upward from the griddle surface to maximize crust development. The open lid also lets you monitor the browning in real time so you can flip at exactly the right moment.

Why steam the buns in a foil pan with a damp paper towel?

Steaming the brioche slider buns for about 3 minutes makes them soft, pillowy, and warm without toasting or drying them out. A toasted bun on a smash burger slider competes texturally — you want a soft, yielding bun that gives way to the crispy patty rather than adding its own crunch. The damp paper towel in the foil pan creates a gentle steam environment that warms the buns evenly without making them soggy.

Can I cook this Indoors?

We rate this a 3 out of 5 for cooking indoors. Works indoors with adjustments, but the grill is recommended. A cast iron griddle or skillet on the highest stovetop setting replicates the smash technique well — the Maillard crust, the onion embedding, and the cheese melt all happen exactly the same way. What you give up is the subtle hickory backdrop from the pellet grill, which adds a quiet smoky note to the crust that an indoor kitchen can't reproduce.

Recipe Highlights & Insights

• The smash itself needs to happen within the first 30 seconds of the beef hitting the griddle — before any crust forms on the bottom. Once the exterior starts to set, pressing down no longer spreads the patty effectively and you lose the maximum surface contact that creates the lacy, crispy edge. Press hard, press fast, and use parchment paper between the press and the beef so nothing sticks.

• Meat Church Blanco is an intentional seasoning choice for this recipe. It's an all-purpose seasoning built around salt, pepper, garlic, and a clean, savory backbone — exactly what a smash burger needs. High-sugar rubs burn on a 450°F griddle in under a minute. Blanco has low enough sugar content that it seasons the crust without scorching, and its garlic note pairs cleanly with the spicy garlic pickle in the finished slider.

• American cheese is non-negotiable for smash burgers and it's not a compromise — it's the technically correct choice. American cheese melts at a lower temperature than any natural cheese and goes fully liquid-smooth in seconds on a hot patty. It coats the surface completely, sealing in moisture and binding the caramelized onions to the patty. Cheddar, Swiss, or provolone all either take too long to melt or break into greasy pools at this temperature.
