Creamy White Cheddar Onion Dip with Caramelized Onions

This white cheddar onion dip is hot, bubbly, and packed with sharp white cheddar, cream cheese, herbs, and the mild sweetness of Vidalia onion. Perfect for parties or casual snacking.

I get cravings for dips all the time. They’re ideal for unpredictable gatherings: easy to prepare, simple to reheat if plans change, and generous enough to feed a crowd or just a hungry household. For a recent Fourth of July I grabbed some blue tortilla chips to be festive, shredded cheese, diced Vidalia onion, mixed everything in a bowl, and baked it. In about 30 minutes the dip was hot, golden, and ready to serve. It’s one of those recipes that disappears quickly because people love the creamy cheese and mild onion flavor.

WHITE CHEDDAR ONION DIP

CHOOSING AND STORING ONIONS

• Choose onions with smooth, dry, papery skin and tightly closed necks.
• Avoid onions with soft spots, dark patches under the skin, or sprouts.
• Vidalia onions are sweeter and have higher water content, so they won’t store as long as standard yellow onions.

STORAGE TIP

• Store onions in a cool, dark, well-ventilated place, like a pantry. Vidalias will last about 1–2 weeks when stored properly.

Tip: seasonal produce guides and recipe roundups often include helpful selection and storage information for onions and other vegetables.

WHAT YOU’LL NEED

Start by shredding the white cheddar and dicing the Vidalia onion. For the best texture and sharpness, shred a block of cheddar rather than using pre-shredded cheese when possible.

Preheat your oven to 375°F (190°C).

In a medium bowl, combine:

• 3 cups shredded white cheddar (about one 8-ounce block)
• 2/3 cup finely diced Vidalia onion (about one small-medium onion)
• 2/3 cup mayonnaise
• 6 ounces cream cheese, softened
• 1 teaspoon freshly ground black pepper
• 1/2 teaspoon Italian seasoning
• 1/2 teaspoon Old Bay seasoning

Mix until well combined. Transfer the mixture to a baking dish and spread it evenly. Bake at 375°F for 25–30 minutes, until the top is golden brown and the dip is hot and bubbly throughout.

Remove from the oven and let rest a few minutes before serving. This dip is rich and creamy, with a pleasant tang from the mayonnaise and cream cheese and a savory hit from the white cheddar and seasonings. Serve warm with tortilla chips, pita chips, toasted baguette slices, or a selection of fresh vegetables for dipping.
