Spiced Sliders With Date Ketchup

• 1 tablespoon olive oil
• 1/2 small red onion, finely chopped
• 1 cup ketchup
• 1 cup Medjool dates, pitted, chopped
• 1/2 cup pale lager
• 2 tablespoons apple cider vinegar
• Kosher salt, freshly ground pepper
• 1/2 small red onion, finely chopped
• 2 garlic cloves, finely chopped
• 1 pound ground lamb
• 8 ounces ground beef
• 1/4 cup finely chopped fresh flat-leaf parsley
• 1 tablespoon baharat (spice blend)
• Kosher salt, freshly ground pepper
• 1 tablespoon vegetable oil
• 12 slider buns, split, toasted
• Bibb lettuce, caramelized onions, and sliced feta (for serving)

1. Heat oil in a small saucepan over medium heat. Cook onion, stirring occasionally, until beginning to brown, 5-8 minutes. Add ketchup, dates, and beer; bring to a boil, reduce heat, and simmer, stirring occasionally and adding water as needed to prevent burning, until thick and slightly darkened, 20-25 minutes.
2. Remove pan from heat and stir in vinegar. Let mixture cool slightly. Puree in a blender, thinning with water if needed, until smooth; season with salt and pepper. Let cool.
3. DO AHEAD:
4. Using your hands, gently mix onion, garlic, lamb, beef, parsley, and baharat in a large bowl; season with salt and pepper. Form scant 1/4-cupfuls of lamb mixture into twelve 2"-diameter patties.
5. Heat oil in a large skillet over mediumhigh heat. Place patties in skillet and immediately reduce heat to medium. Cook about 3 minutes per side for medium-rare. Serve patties on buns with date ketchup, lettuce, caramelized onions, and feta.
