French Onion Mashed Potatoes

French onion mashed potatoes are rich, buttery, and deeply savory — the ultimate comfort side with a gourmet twist. Yukon gold potatoes are blended with Gruyère, sour cream, and caramelized shallots for layers of creamy, nutty flavors that sing French onion soup. Topped with golden shallots and fresh thyme, this dish is pure cozy luxury in every bite.
