Step 1: Caramelize the Onions
In a large skillet, melt the butter over medium-low heat. Add the sliced onions and a pinch of salt. Stir occasionally and let the onions cook slowly, stirring every few minutes, until they are golden brown and caramelized (about 25-30 minutes). Patience is key here—low and slow is the way to go!
Step 2: Add Garlic and Thyme
Once the onions are caramelized, add the minced garlic and thyme to the pan. Stir and cook for an additional 1-2 minutes until fragrant. Then, remove from heat and let it cool slightly.
Step 3: Mix the Dip Base
In a large bowl, combine the cream cheese, sour cream, and mayonnaise. Mix until smooth and creamy.
Step 4: Combine
Add the cooled caramelized onion mixture to the creamy base and stir everything together. Taste and adjust with salt and pepper to your liking.
Step 5: Chill and Serve
For the best flavor, refrigerate the dip for at least 30 minutes before serving to let all the flavors meld together. It’s totally worth the wait! Serve with your favorite chips, crackers, or fresh veggies, and get ready for the compliments.
