Ingredients and Their Purpose
- 1 tablespoon butter – The foundation for caramelization, butter adds richness and helps develop the onions’ deep golden color.
- 2 medium yellow onions, roughly chopped – Yellow onions are ideal for caramelizing thanks to their natural sweetness and balanced flavor.
- 8 oz cream cheese, softened – Provides a thick, creamy base and luxurious mouthfeel.
- 1 cup sour cream – Adds tang and lightness, balancing the richness of the cream cheese.
- 1/3 cup mayonnaise – Enhances creaminess and gives the dip a smooth, cohesive texture.
- 1 cup Swiss or Gruyère cheese, grated – These cheeses melt beautifully and contribute nutty, savory depth reminiscent of classic French onion soup.
- 1/2 teaspoon onion powder – Reinforces the onion flavor without overpowering the fresh caramelized onions.
- 1/2 teaspoon garlic powder – Adds gentle warmth and savory balance.
- 1 teaspoon Worcestershire sauce – Delivers umami richness and complexity.
- 1/2 teaspoon black pepper – Provides subtle heat and contrast.
- Kosher salt, to taste – Essential for enhancing all flavors.
Step-by-Step Preparation
1. Caramelize the Onions
In a large heavy-bottomed skillet over medium-low heat, melt the butter. Add the chopped onions and season lightly with salt. Cook slowly, stirring every few minutes, allowing the onions to soften, release moisture, and gradually turn deep golden brown. This process takes about 20 minutes and is key to achieving the dip’s signature flavor. Do not rush this step.
2. Preheat the Oven
Preheat your oven to 350°F (175°C). Lightly grease a small baking dish or oven-safe skillet.
3. Mix the Creamy Base
In a medium mixing bowl, combine the softened cream cheese, sour cream, and mayonnaise. Mix until completely smooth and lump-free.
4. Build the Flavor
Fold in half of the grated cheese, the caramelized onions, onion powder, garlic powder, Worcestershire sauce, and black pepper. Taste and adjust salt as needed.
5. Bake to Perfection
Transfer the mixture to the prepared baking dish. Sprinkle the remaining cheese evenly over the top. Bake uncovered for 20–25 minutes, or until the dip is hot, bubbly, and lightly golden on top.
6. Rest and Serve
Allow the dip to cool for 5 minutes before serving. This helps the flavors settle and improves texture.
