Preheat your oven to 350°F (175°C).

In a skillet over medium heat, add a tablespoon of olive oil and the finely chopped onion. Cook for about 8-10 minutes until soft and golden.

Add the minced garlic to the skillet and sauté for 1-2 minutes until fragrant.

In a large mixing bowl, combine the softened cream cheese, sour cream, and mayonnaise. Blend until smooth.

Add the grated smoked Gouda, Worcestershire sauce, Dijon mustard, and the onion-garlic mixture to the bowl. Stir gently.

Season the dip with salt and pepper to taste.

Transfer the dip mixture into a baking dish and spread it evenly.

Bake for 20-25 minutes until heated through and bubbly.

Allow to cool for a few minutes, then garnish with fresh chives before serving.

Serve warm with tortilla chips, toasted bread, or fresh vegetables.
