Ingredients
Scale
3 large yellow onions, thinly sliced
2 tablespoons unsalted butter
1 tablespoon olive oil
1 teaspoon salt, plus more to taste
1/2 teaspoon black pepper
1 teaspoon fresh thyme leaves
8 ounces cream cheese, softened
1 cup sour cream
1/4 cup mayonnaise
1 clove garlic, minced
1/4 cup grated Gruyere cheese (optional, for extra richness)
Instructions
Heat the butter and olive oil in a large, heavy-bottomed skillet over medium heat. Add the sliced onions and 1 teaspoon of salt.
Cook the onions slowly, stirring every 5 to 7 minutes, for 45 to 60 minutes. Reduce the heat to low if the onions start to brown too quickly. You want them deeply golden brown and sweet, not burnt.
When the onions are fully caramelized, stir in the fresh thyme and minced garlic. Cook for 1 minute until fragrant. Remove the skillet from the heat and let the onions cool slightly.
In a medium bowl, combine the softened cream cheese, sour cream, and mayonnaise. Mix until smooth.
Fold the cooled caramelized onions and thyme mixture into the cream cheese base. If using, stir in the grated Gruyere cheese.
Season the dip with black pepper and adjust salt as needed.
For the best flavor, cover the dip and chill it in the refrigerator for at least 2 hours to allow the flavors to meld.
Serve cold or warm it gently in an oven-safe dish at 350°F (175°C) for 15 minutes before serving as a warm onion dip appetizer.
Notes
Serve this ultimate dip for gatherings with sturdy potato chips, toasted baguette slices, or fresh vegetable sticks like carrots and celery.
For a Gordon Ramsay-inspired depth, ensure you cook the onions low and slow; this step creates the essential savory base.
This dip tastes better the next day, making it an excellent make-ahead party snack.
