This homemade French onion dip takes the familiar party favorite and elevates it with deeply caramelized onions, warm spices and a creamy base that feels nostalgic and fresh at the same time.

Slowly cooking onions in butter brings out their natural sweetness, turning them soft, golden and full of flavor. When folded into a blend of sour cream and mayo, they create a dip that’s rich, savory and irresistibly scoopable.

It’s the kind of recipe that makes you rethink store-bought dip. The homemade version is brighter, richer and packed with real onion flavor. Whether you’re making this for game day, a holiday spread or a simple movie night snack, it’s a dip that keeps everyone coming back for another bite.

I’ve made this dip at least a dozen times since I first tried it and it’s become a staple for hosting people and game days! It’s so easy to make with two simple steps, cooking the onions in seasoning and mixing with the sour cream and mayonnaise. I normally have all of the ingredients on hand, which makes it extra simple! It’s perfect for making ahead because it needs to refrigerate for a few hours!
