Dip Variations
This recipe is easily customizable and can easily be served as a warm, and cheesy, onion dip variation!
Follow the recipe above but instead of placing the dip in the fridge, put the dip in an oven safe baking dish, sprayed with non-stick spray, and fold in a ½ cup of mozzarella cheese.
Then top with your favorite cheese! Cheddar or mozzarella cheese would be perfect here! Then place in the oven on 350 degrees Fahrenheit for 20-25 minutes until the cheese is melty and bubbly! Serve with some chips, veggies, or your favorite crackers!
Equipment
For this recipe, all you need is a medium-sized frying pan for caramelizing the onions and then a large mixing bowl for making the onion dip. That is all! Two pieces of equipment!
If making the warm variation, you will need an additional oven safe baking dish and a spatula to fold in the cheese. No fancy equipment needed for this recipe!
Dip Storage
Store your onion dip in an air tight container in the fridge for up to 4-5 days. Each day that you store the onion dip in the fridge, the flavor develops more and more!
I would avoid freezing this recipe due to this dip not holding up well to freezing and then defrosting.

Frequently Asked Questions (FAQs)
Caramelized onion dip is made of caramelized onions, yogurt or sour cream, onion powder, and mayo. This recipe is mixed together well and then stored in the fridge until ready to serve.
To caramelize onions quickly, I recommend using a pan set to medium heat, seasoning your onions with salt to help the onions break down, and add a little sugar to encourage the onions to caramelize quicker.
You can caramelize onions with butter or oil. I often will use olive oil to caramelize onions for savory recipes. Either butter or oil will add the liquid needed to help the onions break down and caramelize.
