⚾🍔 We tested Bad Daddy's new Ballpark Burger and it absolutely lives up to the stadium food hype! That seven-ounce patty is massive and incredibly juicy—cooked to a perfect medium with a nice char. The savory onion jus is what makes this special; it soaks into the brioche bun without making it soggy, creating this rich, French onion vibe. Compared to their regular burgers, the caramelized onions here are sweeter and more jammy. Honestly, it's worth the calories. Our verdict: stadium flavors done right.
Caramelize the onions: Thinly slice the onion. In a skillet over medium-low heat, add 1 tbsp butter and 1 tbsp olive oil. Add onions and a pinch of salt, then cook slowly until deeply golden and jammy (about 18–20 minutes). Stir in brown sugar and balsamic during the last 5 minutes.
Prepare the onion jus: In a small saucepan, combine beef stock, Worcestershire sauce, and 2 tbsp of the caramelized onions. Simmer over medium heat 3–5 minutes until reduced by half and rich, seasoning with black pepper to taste.
Form and season the patty: Shape the 7 oz ground chuck into a thick, even patty, taking care not to overwork. Season both sides generously with kosher salt and black pepper.
Grill the burger: Heat a cast iron skillet or grill to medium-high. Grill the patty 4 minutes per side for medium, topping with a slice of provolone in the last minute. Let rest 2 minutes off heat.
Bun and build: Butter the brioche bun and toast cut sides in a skillet until golden. To assemble, place the patty on the bottom bun, top with a generous mound of caramelized onions, and spoon the warm onion jus over. Add top bun. Serve immediately, stadium-style.
Craft burger tip: For true Bad Daddy's flavor, don't rush the caramelization—the jammy, sweet onions and deeply beefy jus set this apart!
