Blackstone Smash Burger Recipe with Onions
Description
This recipe prepares smash burger meatballs using ground chuck mixed lightly with kosher salt, garlic powder, black pepper, and optionally beef bouillon for enhanced flavor. After chilling briefly, the meatballs are flattened on a high-heat surface to develop a crispy sear called the 'smash'.
Caramelized onions are prepared separately by sautéing thinly sliced onions in butter with a pinch of salt over medium heat until they are softened and golden, adding a sweet counterpart to the savory burger. Brioche buns are buttered and then grilled to a golden-brown crust, bringing a soft yet slightly crisp vehicle for the burger and toppings.
Optional toppings include a homemade smash sauce, shredded lettuce, tomato slices, and pickles to complete the assembly. Leftover patties and pre-formed meatballs can be stored refrigerated for several days or frozen to maintain freshness and convenience. The smash sauce is a simple mix of mayonnaise, sweet pickle relish, Dijon mustard, lemon juice, and seasoning salt, chilled before serving.

Instructions
Prepare Smash Burger Balls
- In a medium bowl add ground chuck, and sprinkle the following evenly over the meat; kosher salt, black pepper, garlic powder, and if using bouillon. Mix quickly, careful not to overwork the meat. Divide meat into 8 similar-sized meatballs.
- Return the burger balls to the refrigerator or freezer until ready to grill, no longer than 20 minutes in the freezer.
Prepare Smash Sauce (optional)
- Mix all the sauce ingredients in a small bowl, and place in the fridge until ready to use.
Grill Onions
- If making caramelized onions, on the flat top grill, over medium heat, melt butter and add sliced onions, sprinkling with salt. Grill, tossing occasionally until caramelized, about 15 minutes. Scoot to the back and side, where they can continue cooking, stirring occasionally.
Grill Buns
- Butter buns and grill until golden brown, set aside. Have toppings sliced and ready to build your smashburger.
Grill Smash Burgers
- Increase grill temperature to the higher side of medium-high heat. Once hot, place 4 burger balls onto the griddle, to keep the meat from sticking, place a square of parchment paper onto the top of the meatball, then immediately smash straight down on the burgers, so they become a thin patty.
- Use a wide steel spatula, you may have to use your hand or something else to push down on the spatula or a burger press (you may also use the bottom of a large glass or jar).
- Grill for 2 minutes, flip, add cheese if desired, and cook for 1-2 minutes. Add cheese during last minute or two until melted.
- Build your burger, by adding smash sauce to the bottom bun, adding shredded lettuce, a slice of tomato, and pickles, then add burger(s) and top with caramelized onions topping with the top bun.
Notes
- Use 80/20 ground chuck for optimal flavor and texture in smash burgers.
- Store leftover patties in an airtight container in the refrigerator for up to 4-5 days.
- To freeze, store pre-portioned meatballs or cooked burgers in freezer-safe containers and thaw before cooking or reheating.
- Smash sauce combines mayonnaise, sweet pickle relish, Dijon mustard, fresh lemon juice, and seasoning salt; refrigerate until needed.
