This baked onion dip recipe comes from a family friend! She used to have a catering business. This was the most popular item on her menu! It’s a crowd pleaser!

The dip tastes like a hot version of the cold french onion dip you can get from the store. It’s hot and bubbly and caramelized. So delicious!!

Should I use a vidalia onion, sweet onion, or yellow onion?

All of these will work in this dip! All basically the same kind of onion.

How to prevent your onion dip from turning out oily?

Make sure to use light mayo! This will reduce the amount of oil in the dip.

You can also use a cast iron if you want it even less oily. A cast iron will soak up all the grease that typically pools on the tops of baked dips!

What size baking dish should you use?

An 8×8-inch baking dish is the best! But a 9-inch pie plate or cast iron pan also works.

The pictures in this blog post are of the dip baked in a 10.25-inch cast iron. I wouldn’t go larger than 10.25 inch though.

What to serve with this hot onion dip?

We serve it with frito scoops. They’re super sturdy and pair really well with the onion flavor.

But you could also serve it with a sliced baguette.

What to do with the leftovers?

Melt it over steaks. It’s incredible!!

Make the steaks the way you normally would. Then spread some of the dip over top of each steak. Broil until the dip is melted.
