🥘 Ingredients

• 2 tablespoons Butter
• 3 medium Yellow onions
• 1 teaspoon Salt
• 0.5 teaspoons Granulated sugar
• 8 ounces Cream cheese

📝 Instructions

12 steps

1. Peel and thinly slice the yellow onions.

2. In a large skillet, melt the butter over medium heat.

3. Add the sliced onions and sprinkle with salt and sugar. This helps draw out moisture and enhances caramelization.

4. Cook the onions, stirring occasionally, for 25–30 minutes until they are deeply golden and caramelized. Lower the heat if they begin to brown too quickly.

5. In a medium mixing bowl, combine the cream cheese, mayonnaise, sour cream, shredded Gruyère cheese, garlic powder, thyme leaves, and black pepper.

6. Once the onions have caramelized, remove the skillet from the heat and let them cool slightly.

7. Chop the caramelized onions roughly into smaller pieces and add them to the cheese mixture. Stir until well combined.

8. Preheat your oven to 375°F (190°C).

9. Transfer the mixture to an oven-safe baking dish and spread it evenly.

10. Bake in the preheated oven for 15–20 minutes, or until the top is bubbling and lightly golden.

11. Remove the dish from the oven and let it cool slightly before serving.

12. Serve warm with crackers, toasted baguette slices, or fresh vegetable sticks.
