Southern 3-Ingredient Baked Onion Dip

This 3-ingredient baked onion dip is the kind of dish that disappears quickly at church potlucks and neighborhood gatherings before you’ve even set the spoon down. It uses a classic Southern approach: combine a simple pantry staple like condensed soup with plenty of cheese, then let the oven bring everything together. The result is a bubbling dish of sweet onions folded into a creamy, cheesy base with golden, caramelized edges. Easy to make, quick to prepare, and always a conversation starter when people realize how simple it is.

Serve it hot straight from a cast iron skillet with sturdy dippers like thick-cut potato chips, toasted baguette slices, buttery crackers, or warm pita wedges. For a fresher contrast, add a veggie platter with celery sticks, bell pepper strips, and carrot coins. It pairs nicely with cold sides and iced tea at gatherings, or alongside heartier dishes like wings, ribs, or pulled pork for game day spreads.
