Ingredients

• 2 tablespoons Unsalted butter
• 1 tablespoon Olive oil
• 3 large Yellow onions (thinly sliced)
• 0.5 teaspoon Kosher salt
• 0.5 teaspoon Granulated sugar
• 8 ounces Cream cheese (softened)
• 0.5 cup Sour cream
• 0.25 cup Mayonnaise
• 1 cup Parmesan cheese (finely grated)
• 0.5 teaspoon Garlic powder
• 0.25 teaspoon Black pepper

Directions

Step 1

In a large skillet, heat the butter and olive oil over medium heat until the butter is melted.

Step 2

Add the sliced onions to the skillet, then stir in the kosher salt and granulated sugar to help with caramelization.

Step 3

Cook the onions over medium heat, stirring occasionally, until they are golden brown and caramelized, about 25-30 minutes. Lower the heat if necessary to prevent burning.

Step 4

Once the onions are caramelized, remove them from the heat and let them cool slightly.

Step 5

In a large mixing bowl, add the cream cheese, sour cream, and mayonnaise. Mix until smooth and creamy using a hand mixer or whisk.

Step 6

Fold in the grated Parmesan cheese, garlic powder, and black pepper until well combined.

Step 7

Chop the cooled caramelized onions into smaller pieces if desired, then fold them into the creamy mixture.

Step 8

Transfer the dip to a serving bowl and refrigerate for at least 30 minutes to allow the flavors to meld together.

Step 9

Serve the Onion Parmesan Dip chilled or at room temperature with your choice of crackers, bread, or fresh vegetables.
