Sweet Vidalia onions are the star of this hot homemade onion dip.
What are Vidalia onions
If you’re not from the South you may not be familiar with Vidalia onions. They are a sweet onion that is grown in Vidalia Georgia. It seems that the soil in that area produces a sweeter less pungent onion. These onions are milder than a standard onion which means it’s great to serve on sandwiches or salads.
They have a higher sugar content and lower sulfer content than yellow onions which gives them their great flavor without making your eyes water.
These mild and sweet qualities make them perfect for a hot onion dip.
This creamy Vidalia onion dip is best served warm, so if you’re making it for a party, a chafing dish is helpful. At our house, this crowd-pleasing dip doesn’t stay around long enough to get cold. If it does, you can warm it in the microwave.
Since it’s a thicker dip, similar to an artichoke dip, or bacon cheese dip, you’ll want to serve it with crackers or toasted baguettes or strong tortilla chips. It’s also great on homemade herbed pita chips which are super simple to make.

What you’ll need
- Vidalia Onions – Grate with a cheese grater or food processor and be sure to squeeze them dry, they will have lots of water and that will make the dip soupy.
- Swiss cheese – you don’t need an expensive aged cheese for this dip.
- Mayonnaise – my favorite is Hellman’s
- Sriracha – a little hot sauce adds flavor without making it spicy, you could use any brand that you like. If you don’t want hot sauce, you could substitute Worcestershire sauce
- Parmesan cheese – this adds flavor
- Paprika – this is sprinkled on the top and adds a little flavor but also come color
How to make this Vidalia onion dip recipe
Step 1
First you need to grate the onions. A food processor is handy but you can also use a cheese grater. Once grated, place it in a colander to squeeze out the onion juice, then press it with a paper towel to absorb as much liquid as possible.
Pro Tip: A food processor works great to grate both the onions and the cheese. Just drain out the liquid from the onions before grating the cheese.
Step 2
Combine the onions and mayonnaise along with the parmesan and Swiss cheeses in a medium bowl.
Pour into 8×8 casserole dish. Sprinkle the top with paprika.
Step 3
Bake at 400 degrees Fahrenheit for 30 minutes or until brown and bubbly
Try serving this before your next dinner party, or have it on hand for Sunday afternoon football.
Pro tip: You can prepare this the day before and bake it before you’re ready to serve.
