What Are Vidalia Onions?

Vidalia onions are known for being extra sweet and mild. They are only grown in Southeast Georgia. If it’s not grown in Georgia it’s not a Vidalia onion. The low sulfur soil they are grown in makes them sweeter. Vidalia onions have less bite than regular yellow onions, which makes them perfect for dips, casseroles, and many Southern recipes.

When baked into this dip, the onions become soft, buttery, and slightly caramelized.

How to Make Vidalia Onion Dip

1. Preheat your oven to 375F.
2. Melt the butter in a 10″ cast iron skillet over medium heat. Add the chopped Vidalia onions and cook for 12–15 minutes, stirring often until the onions are soft and lightly golden. After the onions are cooked remove the pan from the heat and allow onions to slightly cool.
3. In a large mixing bowl, beat together the cream cheese, sour cream, and mayonnaise until smooth.
4. Stir in the Mozzarella, Gruyere, Dijon mustard, hot sauce, Worcestershire sauce, garlic powder, and salt.
5. Fold in the cooked onions until everything is evenly combined.
6. Spread the mixture into the cast iron skillet (same one you used to cook the onions) or a greased 8×8-inch baking dish.
7. Sprinkle the grated Parmesan cheese over top the onion dip.
8. Bake for 25–30 minutes until hot, bubbly, and the top is lightly golden.
9. Garnish with chives or green onions and serve warm.

Tips for the Best Vidalia Onion Dip

• If you like a more caramelized onion flavor, cook the onions a few extra minutes before adding them to the dip.
• Let the cream cheese soften first so the dip mixes smoothly.
• Make sure your Worcestershire sauce is vegetarian friendly. Many brands contain anchovy paste.
• If you don’t have a cast iron skillet you can bake this dip in small casserole dish but with the cast iron you can go straight from stove top to the oven.
• Serve the dip warm for the creamiest texture.

Make Ahead Instructions

You can assemble the dip up to 24 hours in advance.

Simply prepare the dip, spread it into the baking dish, cover tightly, and refrigerate. When you are ready to serve, bake as directed. You may need to add 5 extra minutes to the baking time if the dip is cold from the refrigerator. If using cast iron, going straight from a chilled fridge to a hot oven can cause the metal to crack or warp. To bake safely, place the cold pan into a cold oven and let them heat up gradually together.

Storage

Store leftover Vidalia onion dip in an airtight container in the refrigerator for up to 3 days.

Reheat in the microwave or warm in a 350F oven until heated through.

Variations

Caramelized Vidalia Onion Dip

Cook the onions longer until deeply golden and caramelized for an even richer flavor.

Spicy Vidalia Onion Dip

Add more hot sauce and a pinch of cayenne pepper for a spicy version.

Slow Cooker Version

Mix everything together and cook on low for 2–3 hours, stirring once or twice, until hot and melted. The slow cooker version is perfect for football tailgates!
