My dad makes this 3 ingredient classic for every single cookout.

This 3-ingredient French onion dip is the kind of no-fuss classic my dad makes for every single cookout. It’s the one everyone hovers around, chip in hand, and it disappears so fast we’ve learned to make a double batch before guests even ring the doorbell. This version leans on the Midwestern pantry staple combo of dry onion soup mix and sour cream, a shortcut that dates back to the 1950s when home cooks started stirring soup packets into dairy to mimic the slow-cooked French onion flavor.

The result is thick, creamy, and packed with savory onion and a hint of beefy depth—perfect for casual gatherings when you want maximum payoff with minimal effort.

Serve this French onion dip well-chilled in a clear glass bowl so the creamy white base and dark brown flecks of dehydrated onion are visible. Pair it with sturdy potato chips, ridged if you have them, plus a platter of raw vegetables like carrot sticks, celery, bell pepper strips, and snap peas.

It’s also great with pretzels, pita chips, or spread on burgers and grilled chicken sandwiches instead of mayo. For a full cookout spread, set it next to grilled brats, burgers, and corn on the cob so guests can use it as both a dip and a quick sauce.
