This easy caramelized onion dip is the perfect party food! Serve with chips for the perfect appetizer or snack.
In a large nonstick skillet, melt the butter over medium heat and add the olive oil. Add the onions and stir until they are well coated in the butter and olive oil. Move the onions around so they are in a single layer in the pan. Cook for about 10 minutes, stirring occasionally.
Keep the dip covered in the refrigerator for up to 4 days. It can be made in advance.
