- 1 cup ketchup
- 3 tablespoons bourbon or rye whiskey
- 2 tablespoons apple cider vinegar
- 4 tablespoons brown sugar
- 1 tablespoon Worcestershire sauce
- 1 tablespoon smoked paprika
- 1 teaspoon garlic powder
- 1 teaspoon minced onion
- 1 teaspoon hot sauce
- ½ teaspoon black pepper
- ½ teaspoon kosher salt
- 2 pounds sirloin steak, cut into 1 ½-inch cubes
- 1 teaspoon kosher salt
- 1 teaspoon black pepper
- 1 teaspoon smoked paprika
- 1 teaspoon garlic powder
- 2 tablespoons grapeseed oil (or other neutral oil)
- 1 teaspoon flaky sea salt
- ⅛ cup fresh flat-leaf parsley, chopped
- Combine all barbecue sauce ingredients in a small saucepan over medium heat.
- Bring the sauce to a gentle simmer. Cook for 8 to 10 minutes, stirring occasionally, until slightly thickened. Remove from heat and set aside.
- Pat the steak cubes completely dry with paper towels. Toss with salt, pepper, smoked paprika, and garlic powder until evenly coated.
- Heat oil in a large cast iron skillet over high heat until smoking.
- Add steak bites in a single layer, working in batches if needed to avoid overcrowding. Sear for 1 to 2 minutes per side, until deeply browned on all sides.
- Remove the steak bites from the pan, pour half of the barbecue sauce over them, and toss to coat. Return to pan, and cook on medium heat for 1 minute until the sauce caramelizes slightly around the bites.
- Transfer the bites to a serving platter.
- Drizzle steak bites with remaining barbecue sauce, sprinkle with flaky salt and parsley, and serve with toothpicks.
