Baked French Onion Dip

Baked French Onion Dip
Ingredients
1 tablespoon unsalted butter
2 medium yellow onions, coarsely chopped
8 ounces cream cheese, brought to room temperature
1 cup sour cream
⅓ cup mayonnaise
1 cup shredded Swiss or Gruyère cheese
½ teaspoon onion powder
½ teaspoon garlic powder
1 teaspoon Worcestershire sauce
½ teaspoon freshly ground black pepper
Kosher salt, as needed
Instructions
Caramelize the Onions
Melt the butter in a large, heavy skillet over medium-low heat.
Add the chopped onions, season lightly with salt, and cook slowly, stirring every few minutes, until they become deeply golden and caramelized, about 20 minutes.
Heat the Oven
Preheat the oven to 350°F (175°C).
Prepare the Creamy Base
In a medium mixing bowl, stir together the softened cream cheese, sour cream, and mayonnaise until smooth and fully blended.
Combine the Flavors
Fold in half of the grated cheese, the caramelized onions, onion powder, garlic powder, Worcestershire sauce, and black pepper.
Mix until evenly incorporated, then adjust salt to taste.
Assemble and Bake
Spoon the mixture into a baking dish and spread evenly.
Sprinkle the remaining cheese over the top.
Bake Until Golden
Bake for 20–25 minutes, or until the dip is hot, bubbly, and lightly browned on top.
Serve warm and enjoy.
