This steakhouse-inspired dip captures the iconic flavors of a bloomin' onion without the heavy frying process. Whole sweet yellow onions take on a deep, wood-smoked char on the grill before being chopped and folded into a creamy base of sour cream, mayonnaise, and sharp horseradish. Spiced with paprika, garlic, and a hint of cayenne, it delivers an intensely savory, tangy spread perfect for dipping chips, pretzels, or fresh vegetables.
