These Smashed French Onion Potatoes turn a classic soup into a crispy, cheesy, hand-held bite that’s perfect for parties. Each potato is smashed into a muffin tin to form a golden cup, then filled with jammy caramelized onions and topped with melted Gruyère. A quick trip under the broil creates bubbling, browned tops and crispy edges. Think of them as the ultimate French onion soup, no spoon required!
