The dip has a slightly crispy, bubbly cheese layer on top with visible melted cheese and soft cooked onions mixed throughout. On the right side of the skillet, several toasted slices of bread are partially dipped into the creamy cheese mixture.

Ingredients

2 large chopped sweet onions (Vidalia recommended)
2 tablespoons unsalted butter
1 cup mayonnaise
4 ounces softened cream cheese
1 teaspoon garlic powder
1 teaspoon dried thyme
½ teaspoon salt
1 cup shredded cheddar cheese
1 cup shredded smoked gouda cheese
Chopped parsley (for garnish)

Instructions

Step 1: Preheat your oven to 375 degrees Fahrenheit. In a large oven-safe skillet, melt 2 tablespoons of unsalted butter over medium heat.
Step 2: Add the chopped sweet onions to the skillet and cook, stirring occasionally, until they are soft and tender, about 15 minutes.
Step 3: Remove the skillet from the heat. Stir in the mayonnaise, softened cream cheese, garlic powder, dried thyme, salt, shredded cheddar cheese, and shredded smoked gouda cheese until everything is well combined.
Step 4: Transfer the skillet to the oven and bake the dip for 25 minutes or until it is bubbly and golden on top.
Step 5: Remove from the oven, garnish with chopped parsley, and serve warm with crackers, crostini, or bread.

Tips & Variations

Use a mix of sweet onions like Vidalia for the best natural sweetness and depth of flavor.
For extra smokiness, add a pinch of smoked paprika to the mixture before baking.
Substitute cream cheese with Greek yogurt for a lighter dip without sacrificing creaminess.
Try adding a splash of Worcestershire sauce or hot sauce for an added zing.

Storage

Store any leftover dip in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven until warmed through, stirring occasionally to maintain a smooth texture.
