Start by peeling and thinly slicing your onions. Don’t worry about being perfect—once they caramelize, they’ll be soft and delicious.
Melt your butter in a pan over medium-high heat and toss in those sliced onions. Stir them occasionally to keep them from burning. Once they start to brown, lower the heat to medium-low and let them slowly cook to perfection. The trick is patience! Caramelizing takes about 20-25 minutes, but it’s worth it for that sweet, golden goodness.
While your onions are doing their thing, grab a food processor and add the cream cheese, sour cream, and mayonnaise. Season it up with salt and pepper, then blend until smooth and creamy.
Once your onions are beautifully caramelized, let them cool for a few minutes (about 5 minutes is perfect). Add them to the food processor and give it a quick pulse—just enough to mix the onions into the creamy base while still keeping some texture.
Scoop your caramelized onion dip into a bowl, sprinkle with chopped chives for a fresh finish, and serve it up with your favorite chips. This dip is also amazing with veggie sticks or even spread on bread for a twist!
