- 1 tsp salt, divided

How to Make Caramelized Onion Dip and Beans
Step-by-Step Instructions
Prepare the Caramelized Onions: Heat butter in a large skillet over medium-low heat. Add sliced onions, half the salt, and sugar if using. Cook slowly, stirring occasionally, for 25-30 minutes until onions turn deep golden brown and become jammy in consistency. The key is patience – rushing this process will result in burnt rather than caramelized onions.
Cool the Onions: Remove caramelized onions from heat and let them cool completely. This prevents the dairy ingredients from curdling when mixed.
Create the Dip Base: In a mixing bowl, combine sour cream, mayonnaise, remaining salt, black pepper, Worcestershire sauce, and lemon juice. Whisk until smooth and well incorporated.
Combine Ingredients: Fold the cooled caramelized onions into the creamy base, mixing gently to distribute evenly while maintaining some onion texture.
Chill and Serve: Refrigerate the dip for at least 2 hours to allow flavors to meld. Garnish with fresh chives or parsley before serving.
Helpful Tips
Start the onion caramelization process early, as it cannot be rushed. Low and slow cooking is essential for developing the proper sweetness and color. If onions begin to stick or brown too quickly, reduce heat and add a splash of water. For extra depth, add a splash of balsamic vinegar during the last few minutes of caramelizing. Taste and adjust seasoning after chilling, as flavors can change once cooled.

For a lighter version, substitute Greek yogurt for mayonnaise, which adds protein while maintaining creaminess. The dip can be made vegetarian by using olive oil instead of butter. To make it dairy-free, use vegan sour cream and mayonnaise alternatives. The caramelized onions can be made up to 3 days ahead and stored in the refrigerator, making this recipe perfect for meal prep.
